Biological Warfare Agents

The use of biological agents in warfare has been in existence since the time of the well poisoners in ancient Greece and Rome. Only in modern times has Biological Warfare (BW) become a concept which has frightened those who understand the ramifications. Their contagiousness and reproductive abilities, the very features which makes biological agents effective, also make them highly uncontrollable and likely to attack the users as well as the targets. One only has to consider the spread of HIV and Ebola from Central Africa to every nation of the world to understand how uncontrollable a disease organism can be. BW is essentially the intentional release of disease organisms into the atmosphere and those organisms' spread can be just as dramatic.

The rules in this chapter consider biological agents which have been examined by modern military forces and provides data on their application and symptoms. The agents are broken down into viral, rickettsial, bacterial, and mycotal agents.
 
 
 
Biological Weapons
The term biological weapon refers to a means of attack where the offensive item is a biological agent. Biological agents are living organisms which are intended to cause diseases or death in human, animal, or plant life. They are organisms which are highly contagious and rely on this and their ability to reproduce to maintain their impact on a targeted population. This makes the agents strategic weapons, and they are quite capable of devastating entire cities or nations with their effect being limited only by how much contact the infected have with the rest of the population.
In many of these agent's cases, medical science does not allow anything more than therapy of symptoms, there being no therapy to treat the agent itself. In such cases, human and animal targets must rely on their own immune systems to combat an infection, and often, the immune system is simply inadequate.
 
Modern Background:
Research into the nature of disease organisms in the ninteenth century brought forward the idea among militaries that bacteria and other agents could be controlled and used as a means of attacking an enemy. The ability to control such agents, and use them to attack enemy troops was an appealing one, for disease at the time was more lethal than any other weapon. Prior to the twentieth century, disease had been a factor among militaries on campaigns and more troops had died of disease than of enemy steel and fire.
Advances in firearms during the late ninteenth century made disease a less prominent feature on the battlefield, and it was not until firepower bogged down in the muddy trenches of World War I that the idea of alternative weapons such as chemical and biological agents was seriously considered.
Biological weapons were not used in that war, and in 1925, the Geneva Protocol, recognizing the danger of "alternative weapons," banned the use of bacterial agents. Despite the protocol, research into such weapons continued.
During World War II, the British, in cooperation with the Americans and Canadians tested bacteriological and chemical weapons. One of the weapons systems tested was anthrax, code named Agent N, which was placed into bombs which were dropped from cranes on Gruinard Island, just off the coast of Scotland. The testing has contaminated the island's soil with anthrax, and the island remains under quarantine to this day. In Europe, the Nazi governement of Germany was conducting horrible medical experiments on concentration camp prisoners, including exposing them to potential BW agents.
On the other side of the world, the Japanese were testing biological agents on prisoners of war. The Japanese Unit 731 was officially titled the "Kwantung Army Anti-Epidemic Water Supply and Purification Department", but its real purpose was to experiment with bacteria as weapons of war. At least 3000 prisoners of war, ranging from Chinese to Soviet to American, were exposed to biological agents, and more than 1000 of those prisoners died as a result. Also, there are reports that Unit 731 was involved in the release of anthrax and paratyphoid (not listed) bacteria on eleven Chinese cities between 1940 and 1944.

Following the war, captured members of Unit 731 were brought to the United States and offered amnesty in return for their researches. This began a more intensive research program by the United States into the potentials of BW. Agents were developed and stockpiled by the United States and the United Kingdom, and quite likely by the Soviet Union as well, although the Soviet government has always denied ever possessing BW agents or munitions.
Then, in 1972, these three nations signed the Biological Weapons Convention, which banned all stockpiling of biological agents and biological toxins and their delivery systems. There are at least 100 other signatory nations to this document.
Though there have been allegations that major superpowers are violating the agreement, there is no incontrovertable evidence to support the allegations. The United States points to the Soviet Union's sudden outbreak of anthrax at Sverdlovsk in 1979 as being a BW accident and the reports of Yellow Rain (See Section 2.8) as being evidence of a BW capability. Conversely, the Soviet Union points to the United States' continued research into these agents as evidence of development of a BW capability. Despite these allegations, at present, no nation is expected to possess stockpiles of biological agents for use in a future military conflict.
This does not preclude the use of biological agents as terrorist weapons. The chapter on Chemical weapons has already mentioned the 1980 raid on a West German Red Army Faction safehouse which uncovered a bathtub of botulism culture, and the 1984 efforts of two Canadians to acquire botulism and tetanus culture from a Maryland research facility. These two incidents underscore the potential for use of biological agents by terrorist forces.

At present, the great fear of medical researchers is the potential genetic engineering offers to BW research and development. Although genetic engineering can be used to develop effective vaccines and treatments against many diseases, the risk is that it may be used to make BW agents more lethal or make them more selective. A possible development in BW using genetic engineering is the creation of an ethnic disease, a weapon that attacks only targets of certain racial/genetic characteristics. These are only two of the possibilities which make the future of BW a frightening
one.
 
Administration of Biological Agents
Biological agents use identical methods and munitions as chemical agents. However, the nature of the biological agents upon release and infection varies tremendously from chemical agents.

This section provides rules for resolving contamination and dispersal effects of biological agents.
 
Active Period:
A biological agent upon release passes through an active period during which time it can contaminate and infect its targets without requiring a host body to survive. The active period is listed below for aerial and water release:
 
Active Period
 Agent Type  Aerial  Water
 Virus  36 hrs  7 days
 Rickettsia  48 hrs  7 days
 Bacteria*  4 days  15 days
 Fungi  4 days  4 days
 
* Note that anthrax can survive in spore form indefinitely by infecting the soil. Normally, such a case would require heavy bombardment--a single weapon would be insufficient to cause such contamination. Under heavy anthrax bombardment, the
contaminated zone is deemed permanently contaminated.
 
 
Contamination: Aerial Release
Aerial release methods include groundbursts, aerial spraying, and projectors, and are usually military biological munitions. They are release methods which characterize popular conceptions of biological warfare (BW).

Aerial release methods work by introducing the biological agents into the atmosphere in an aerosol form, much like common chemical chemical agents. When an aerial release munition discharges, it produces a cloud of the agent which proceeds to move downwind at the wind speed and will continue to do so for the full length of the active period. Any area which has been touched by the cloud is contaminated as long as the active period has not elapsed.
Any unprotected person or animal inside a contaminated area during the active period runs a chance of being infected. The contaminated area is deemed to be non-contaminated at the end of the active period.
 
Contamination: Water/Food Release
A less common concept of BW is the use of biological agents to contaminate water or food supplies of targeted populations. It is a very slow, but effective method of attacking a city population or attacking the export/agricultural economy of a nation. By simply introducing the agent into a city's water supply, an attacker could have the agent delivered to his target's kitchen faucet. Modern urban-water supply filtration systems will normally pick out harmful biological agents (and even chemical agents) to prevent such an attack, but if the agent were introduced after the filtration process or if there was no filtration system in place, the effects on the city population would be devastating. The mere hysteria among the targeted population could be as devastating as the effects of the agent.

Also, the introduction of biological agents into food supplies, like grain bins, livestock, processing plants, supermarkets, or restaurants can have similar devastating effects. If biological agents were introduced into imported food shipments prior to inspection, and then discovered, all shipments from the exporter nation to the inspecting nation would stop, causing tremendous harm to the exporter's economy.

The foregoing are reasons why terrorist groups view biological attack through water and food supplies as valuable weapons. Such attacks allow them to target city populations or national economies in a highly effective, yet inexpensive manner.
Biological agents released into water or food supplies behave quite differently than aerial-release weapons. A water-released agent will spread through the entire water system. A food-released agent will not spread and will have an active period equal to the aerial-released active period.
Any person ingesting the water or the food during the active period will be exposed to the biological agent and may become infected.
 
Vectors:
Because the active period has elapsed in a contaminated area does not mean that the area is safe. People and animals can still become infected if they are exposed to vectors.

Vectors are sources of infection which have been established by the biological agent. What has happened is the agent has infected a person, an animal, or even the soil, and the agent can then travel from that Vector to attack an uninfected target using its normal method of transmission. The Vector will remain active until cured, treated, or destroyed. For example, the British experimented with anthrax bombs on Gruinard Island off the coast of Scotland and contaminated the island's soil with anthrax. Though the island is quarantined, thus preventing the infection from spreading, the vector--the contaminated soil--is still dangerous, even fifty years later.

Any person or animal which was infected by the original biological agent cloud or through transmission of the disease from another vector becomes a vector. Soil will almost never become a vector because the required amount of agent to which the soil must be exposed is enormous. Gruinard Island's soil became a vector only after repeated bombing with anthrax.
 
Infection and Disease Rules
The effects of biological agents on characters are determined in three steps: infection, symptoms, and treatment.
 
STEP 1: INFECTION
A character can become infected in two ways. Either he is infected by being in the area contaminated by a biological agent cloud while the cloud is still active, or he can be infected by exposure to a vector.
 
Infection via Contamination:
If a character is exposed without protection to contamination during the active period, he must make a 00-99 roll against the Contraction Number. If he rolls over the contraction Number, he avoids being infected. How the disease is normally transmitted (TRX) does not apply in this situation.
 
Infection via Vectors:
If the character is exposed a vector, the gamemaster checks the Disease Tables to find out how the disease is transmitted (TRX). If the character has been in any of those situations while exposed to the vector, the gamemaster then rolls 00-99 to determine if the character contracts the disease. If the roll is greater than the Contraction Number, the character has managed to avoid being infected.
 
Rolling Under the Contraction Number:
If in either of the above cases, however, the roll is less than or equal to the contraction number, the character becomes infected and contracts the disease, and the gamemaster proceeds to the next step--symptoms. The character will never know that he has been infected until the symptoms manifest themselves. For this reason, the gamemaster should make the contraction roll in secret.
 
Contraction Number:
The contraction number is calculated by taking the disease's Contraction Chance (CTC) and subtracting the character's current HLT score. Any fractions in the HLT score are rounded off to the nearest whole number.

Contraction Number = CTC - Current HLT
 
Example: Niki gets caught in an anthrax-contaminated area after the active period has elapsed, so she is safe from infection that way. However, she comes across a dead soldier and removes her mask to examine him. The dead soldier is a vector for the anthrax used in the attack, and Niki has just contaminated herself by taking in his airborne anthrax particles. The gamemaster secretly rolls 00-99 and rolls a 35. The CTC of Anthrax is 75 minus Niki's HLT of 14 = 61. Since the roll is under the Contraction Number, Niki has contracted anthrax.
 
Methods of Transmission:
Disease transmission through contact with bodily fluids requires that the infected fluid must enter the victim's body in some way. This can include bites, blood transfusions, infected needles, oral contact (such as a kiss), or sexual intercourse unless otherwise specified. Transmission through bites only occurs if the bite breaks the skin. The bite must pass through any clothing and the skin itself before the disease-carrying saliva of the can enter the victim's body. Bites will not penetrate boot-thick leather or any type of armor. The same applies to infected needles.

Disease transmission through airborne particles means that any characters in the proximity of the disease source run the risk of becoming infected. Characters who use air-filtration gear or have an independent air supply are not at risk provided that they decontaminate their clothing prior to removing the air filtration gear. The airborne particles can attach themselves to clothing and later be inhaled by the wearer.

Disease transmission through contaminated food and water only occurs if the characters actually ingest the food or water. Note that this applies even to food obtained or prepared in a settlement.
Disease transmission through contact or contact with infected feces occurs in two stages. The contact itself is harmless, but the character's skin is contaminated. If the contaminated skin comes into contact with a cut on the skin, membranes in the nose, eyes, or mouth, or by contaminating food or water the character ingests, then the character has a chance of contracting the disease.
Disease transmission through flies, fleas, or body lice occurs when the character is in close proximity with the insects. Only an isolation suit that is decontaminated prior to being removed will prevent the insects from passing on their diseases.
 
STEP 2: SYMPTOMS
Symptoms progress through three phases: incubation, early symptoms, and advanced symptoms. During any of these times, the progress of the disease can be arrested by making a Disease Recovery Roll (DRR). This is calculated by taking the RR value of the disease and subtracting the character's current HLT score as well as any modifiers for treatment. If a 00-99 roll is lower than this number, the progress of the disease is arrested. Otherwise the disease continues to the next phase.
 
DRR = RR + HLT + (Treatment Modifiers)
 
A DRR can only be made once at the end of each symptomatic phase.
 
Incubation Period
All diseases pass through an incubation period (IP). During this time, there are no symptoms, and the disease cannot be diagnosed by any medic. However, medics can initiate a program of treatment if they suspect that the circumstances would mean that a disease has been contracted. An example of such a situation would be an animal bite, where the animal was shown or suspected to be infected with a disease. If a DRR indicates that the disease is arrested in the incubation period, then there are no further ill effects.
 
Example: Niki contracted anthrax in the last example, and has been undergoing the Incubation Period unaware of any problem and has not had any treatment. The Incubation Period lasted (random roll of 3 on a (5) = ) 3 days. At the end of the third day, the gamemaster makes a DRR for her. He determines her DRR to be an anthrax RR of -10 plus her HLT of 14 for a DRR of 4. The gamemaster rolls a 72 on a 00-99 and determines that she advances to the early symptomatic phase of the disease.
 
Early Symptomatic Phase
If the disease is not arrested during the incubation phase, the early symptoms begin at the end of the IP. These symptoms will usually debilitate the character and prevent him from engaging in any activity other than resting. A character is treated as being fatigued during this time in addition to suffering from the associated Early Symptoms. The early symptoms last for the amount of time indicated in the brackets.
A medic can attempt to make a diagnosis of the disease based on the symptoms by making a medical skill test (Base Odds = 7). Failure means that he misdiagnoses the disease and he will believe it to be a disease listed under Differential Diagnosis of the disease descriptions. If there is no differential diagnosis listed, then the medic simply cannot identify the disease.
As an alternative, the gamemaster can hand the disease descriptions to the player of the medic character and let him figure out what the disease is based on the description of the symptoms.

A DRR can be made at the end of the early symptomatic phase and if successful, the disease is arrested during this period and the character suffers a debility period equal to the listed Healing Time (HT). During this time, the character is treated as being fatigued. The fatigue associated with the disease is removed at the end of the HT. If the DRR is failed, the disease progresses to the advanced symptomatic phase.
 
Example: Niki, in the early symptomatic phase of anthrax, has been feeling fever and malaise and having labored breathing and coughing. On the first day of the symptoms, the medic attempts to diagnose the problem and rolls a 12 on a 3(6), thus exceeding the needed base odds of 7 plus his own SL of 3. The medic has no idea what the problem could be, but attempts to relieve her symptoms anyhow and confines her to bed. After 3 days, Niki must make another DRR. Since she has not received the treatment required, her DRR remains at RR of -10 plus HLT of 14 for a 4. She rolls a 23 and fails again. She advances to the advanced symptomatic phase.
 
Advanced Symptomatic Phase
During the advanced symptomatic phase, the early symptoms continue and the advanced symptoms are added to the character's list of sufferings. These symptoms last for the amount of time listed in brackets. At the end of this time, a final DRR is allowed. If this DRR is failed, the character dies of the disease. If, however, the DRR is successfully rolled, then the character suffers debility for the HT as he would for the early symptoms.
 
Example: In the advanced symptomatic phase of her anthrax, Niki's symptoms have become much worse. The medic, in desperation, tries a broad-spectrum antibiotic as treatment. After 5 days, Niki makes her final DRR. This time, it is an RR of -10 plus Niki's HLT of 14 plus 30 for the antibiotic therapy for a 34. Niki rolls a 17 and survives the disease. She now suffers a debility of 5 days before she is fully recovered. Had she failed this DRR, she would have died at the end of the advanced symptomatic phase.
 
STEP 3: TREATMENT
The progress of a disease can be arrested through the application of the proper treatment. Each disease has a list of appropriate treatments and only those treatments listed will be effective in combatting the infection. Short descriptions of the various types of treatment are given below. The listed treatments can be used in conjunction with one another.

The effectiveness of treatment varies with the phase of the disease. Each description has a series of effectiveness ratings given in parentheses after the title. The series consists of three numbers separated by slashes. The first number is the effectiveness of the treatment being applied during the incubation period. The second gives the effectiveness of the treatment if it is applied during the early symptoms phase, and the final number is the effectiveness of the treatment if applied during the advanced symptoms phase.
 
Treatments:
 
Antibiotics (5/15/30)
This is a program of pharmaceuticals given to the patient. The pharmaceuticals can either be in pill or injection form. These antibiotics are deemed to be broad-spectrum, meaning that one antibiotic type will be effective against all diseases listed.
 
Restore Fluids (0/5/10)
The restoration of fluids ensures that the patient is not dehydrated by vomiting or excessive sweating. In most cases, this treatment is simply regularly giving the patient something to drink, but in more severe cases, intravenous fluids are used.
 
Relieve Symptoms (0/10/20)
The relief of symptoms is the use of pharmaceuticals or physical means to alleviate the patient's pain or to lower his fever.
 
Rest (0/5/10)
Rest means bedrest and sleep. The patient cannot perform any work if this treatment is to be applied. If he does, then any benefit gained from the treatment is lost.
 
Vaccine (90/65/10)
The vaccine treatment is the injection of a weakened form of the virus into the patient's body in order to build up a resistance to the disease by the body's immune system. Each vaccine is specific to one disease and there is no broad-spectrum vaccine available. There are, however, mixtures of numerous vaccines available where one mixture will protect against a variety of diseases. Note that only the diseases with vaccine listed can use this treatment.
 
SPECIAL NOTE ON VACCINES: The most common use of a vaccine is not as a therapy after infection, but to build up the immune system to prevent infection. Vaccines will provide effective protection to a person for an average of six months following injection. They are normally administered through individual injections of killed or weakened agent into the combatant, although American researchers are expected to be working on aerosol vaccines. Aerosol vaccines would allow, for example, an aircraft to spray and thus immunize an entire city against a specific disease. If an agent has a vaccine, it will be listed in the notes accompanying the agent's description. A vaccinated population will be unaffected by the natural occurrence of the disease, but also by the intentional attacks of the disease-causing agent.
 
Viral Agents
Viral agents have been examined as an integral part of BW research. In many cases, they are the preferred agents because they are easy to manipulate and study, highly contagious, difficult to diagnose, and often cannot be treated except by treating the symptoms.

Viruses are organisms consisting of a protien shell encasing simple genetic material. They are normally inert except when they come in contact with a specific cell. At that point, they link up with the cell wall and inject the genetic material into the cell itself. This genetic material alters the functioning of the cell, possibly by altering the cell's own genetic code. In any case, the cell is now producing more genetic material to match that of the original virus and using the cell's own energy to do it. Eventually, the cell ruptures, releasing hundreds to thousands of new viruses. In some cases, the cell does not rupture, but reproduces itself normally, albeit with its altered genetic code.
The agents discussed in this section have been examined by militaries as potential BW weapons or have been threatened to be used as BW weapons by non-military groups.

Treatment: Relieve Symptoms, Replace Fluids.
RR: 10 HT: 3 Weeks
Notes: Vaccine available. Common in horses and other equine animals. Agent intended to kill.
 
Human Immuno-Deficiency Virus (H.I.V)
Differential Diagnosis: None.
TRX: Contact with bodily fluids. Airborne particles?
CTC: 99
IP: 10(10) Months
Early Symptoms [5 + (3) Months]:
H.I.V. progresses to Acquired Immune Deficiency Syndrome (A.I.D.S.). The immune system is slowly destroyed. Substantial weight loss occurs in later part. Persistent fatigue. Diarrhea. Enlarged lymph glands. Night sweats or fevers. Hairy leukoplakia--a hairy white/grey growth on the toungue.
Advanced Symptoms [3 + (3) Months]: Any or all of the following may develop:
  • Pneumocystis carinii pneumonia (PCP) - Severe shortness of breath and heavy cough.
  • Kaposi's sarcoma - skin cancer manifesting as purplish lumps or patches on the skin or in the gastro-intestinal tract.
  • Brain Infection - confusion, disorientation, loss of concentration.
By this point, the immune system has been destroyed, and the person is highly susceptible to other communicable diseases. His HLT is effectively a -10.
Treatment: Antibiotics? Relieve symptoms
RR: -50 HT: n/a
Notes: Not a lethal virus per se, although at this point in time, H.I.V. is 100% fatal. H.I.V. attacks the human immune system and cripples it permanently. Death does not necessarily come by viral action, but through secondary infections, such as pneumonias, tuberculosis, etc. The gamemaster should use such secondary infections in determining the outcome of an H.I.V. infection. As H.I.V. is a very infectious virus, and thus possibly of military or terrorist interest, it has been included in this book. Potential applications in a BW context include water-release or poisoning a blood supply. It is also possible that the virus could be dispersed as an aerosol from a groundburst, spray tank, orprojector. Whether airborne particles could infect targets is a matter of debate. For the purposes of this book, it is assumed that such infection can occur.
No vaccine available. Agent is intended to kill.
 
At the time of writing, there was a great deal of speculation on the infectious nature of H.I.V. At present, conventional medical thought is that HIV can only be trasnmitted by contact with bodily fluids.

Rickettsial Agents
Rickettsia are the causes of obscure but still dangerous diseases. The difficulty in diagnosing such diseases makes them attractive to BW researchers because it prevents a targeted enemy from being able to effectively counteract them.

Rickettsia are between viruses and bacteria in size and are structurally similar to bacteria. Rickettsia follow similar life patterns to bacteria. However, Rickettsia do not have an adequate cell membrane and, like viruses, are prone to destruction by drying out.

Bacterial Agents
Bacterial agents once made up the bulk of BW agents, although much of the focus has now shifted to viral agents. Part of the reason for the shift of focus is the ease of manipulating viruses, but also there is the drawback that most bacterial infections can be treated quite well with modern antibiotics. Nevertheless, bacterial agents remain an important component of BW.

Notes: Pulmonary Anthrax is common in livestock. It can survive indefinitely in the soil in spore form, although it would require very heavy bombardment for a permanently contaminated anthrax zone to be established. Vaccine available. Agent intended to kill.
 
Brucellosis
Differential Diagnosis: None.
TRX: Airborne particles. Contact.
CTC: 40
IP: 3(10) Days
Early Symptoms [7 Days]:
Chills, fever, weakness with fatigue and exhaustion, severe headache and backache. Night sweats. Abdominal pains.
Advanced Symptoms [14 Days]: Continued, but worsening.
Treatment: Antibiotics.
RR: 30 HT: 1 Week
Notes: Vaccine available. Agent intended to kill.
 
Cholera
Differential Diagnosis: Baccilary Dysentery
TRX: Contaminated food and water
CTC: 50
IP: (5) Days
Early Symptoms: [2 Days]
Diarrhea passing greyish feces, abdominal cramps, vomiting.
Advanced Symptoms: [6+(4) Days] Dehydration, loss of color, clammy skin, shallow breathing, 20% chance of coma.
Treatment: Restore fluids, antibiotics, relieve symptoms, rest.
RR: -5 HT: 14 Days
Notes: Common disease found in unsanitary conditions where food and water may be contaminated by sewage. Vaccine available. Agent intended to kill.
 
Baccilary Dysentery
Differential Diagnosis: Cholera
TRX: Flies, contaminated food and water, contact with infected feces.
CTC: 80
IP: (3) Days
Early Symptoms: [3 Days]
Blood and mucus in feces, fever, chills, abdominal cramps.
Advanced Symptoms: [7 Days] Convulsions, lethargy, anorexia, delerium, 50% chance of coma.
Treatment: Restore fluids, relieve symptoms.
RR: 20 HT: 17 Days
Notes: Dehydration may also result from sweating and diarrhea.
 
Meningicoccal Meningitis
Differential Diagnosis: None
TRX: Airborne Particles.
CTC: 45
IP: 5 Days
Early Symptoms [4 Days]:
High fever, chills, and headache. Pain in the back, abdomen, and extremities. Rash on skin and mucous membranes.
Advanced Symptoms [4 Days]: Confusion and delerium leading to coma. Shock (decreased blood pressure). Muscular spasm. Stiff neck. Exaggerated reflexes. Rash has faded.
Treatment: Antibiotics.
RR: 10 HT: 3 Weeks
Notes: A dangerous infection and inflammation of the meninges, a set of membranes which envelop the brain and spinal column. Vaccine available. Agent intended to kill.
 
Pneumonic Plague
Differential Diagnosis: Flu, Influenza, various Pneumonias.
TRX: Contact with rat-borne fleas. Pneumonic is spread by airborne particles (see notes).
CTC: 80
IP: (5) Days
Early Symptoms: [5 Days] Fever, swollen lymph nodes, abdominal pain,
Advanced Symptoms: [10 Days] All early symptoms become progressively worse. Also delerium and black rash (rash is for bubonic only--see notes).
Treatment: Antibiotics, relief of symptoms.
RR: -20 HT: 80 Days
Notes: Both the bubonic and pneumonic plague are caused by the same disease organism. The pneumonic form infects the body through the lungs and so the characteristic black rash does not appear. No vaccine available. Agent intended to kill.
 
Tularemia
Differential Diagnosis: Various pneumonias, cat scratch fever, and menigicoccal and rickettsial infections.
TRX: Airborne particles. Contact.
CTC: Contact with animal tissues. Contact with Insects. Ingestion of contaminated meat or water.
IP: 2(5) Days
Early Symptoms [(3) Days]:
Fever, nausea, and headache begin suddenly, with a papule or pimple forming at the point where
the agent contacted the skin. This papule soon ulcerates. If the agent was ingested, there is gastro-intestinal disturbance, stupor, and delerium.
Advanced Symptoms [(6) Days]: Delerium. Prostration. General aches. Lymph nodes become enlarged and tender and start forming pus.
Treatment: Antibiotics.
RR: 10 HT: 2 Weeks
Notes: A common disease among wild rodents (particularly rabbits) which is normally passed on to man through his interactions with the animals. One attack of tularemia generally confers immunity. Vaccine available. Agent intended to kill.
 
Typhoid Fever (Enteric Fever)
Differential Diagnosis: Viral Pneumonia
TRX: Contaminated food and water.
CTC: 50
IP: 4 + (10) Days
Early Symptoms: [7+(3) Days]
Increasing fever, chills, malaise, coughs, vomiting.
Advanced Symptoms: [7+(3) Days] Stabilizing fever, diarrhea, listlessness.
Treatment: Antibiotics, relief of symptoms, rest.
RR: 10 HT: 7+(3) Days
Notes: 1% of those infected can become carriers. These people do not develop the symptoms but are treated as being vectors for disease transmission purposes. Vaccine available. Agent intended to kill.
 
Fungal/Mycotal Agents
Fungal/Mycotal agents have not been the subject of a great deal of research in the BW field from a disease standpoint. Rather, the focus has been on mycotal toxins, such as trichothecene mycotoxins, a potential component of "Yellow Rain". At present, the United States Army does not consider fungi themselves as antipersonnel weapons. The Soviet Union and its allies have been alleged to be experimenting with mycotal weapons, but this seems to be a drive for mycotal toxins rather than using the organisms themselves as the weapon. Fungal/Mycotal weapons are not expected to be stockpiled nor used in a future conflict. Vaccines do not exist for fungal/mycotal agents, but the United States is examining the possibility of a trichothecene vaccine.
 
Coccidioidomycosis
Differential Diagnosis: Any flu-like disease (not listed). Influenza.
TRX: Airborne particles.
CTC: 60
IP: 3(10) Days
Early Symptoms [(2) Days]:
Fever and chills, severe pain in lungs, muscular ache, backache, cough, general weakness.
Advanced Symptoms [15 Days]: Prostration. Anorexia. Measle-like rash soon followed by development of painless ring-type patches.
Treatment: Rest. Relieve symptoms. Antibiotics.
RR: 45 HT: 4 Weeks.
Notes: Agent intended to incapacitate
