Tularemia is a rare bacterial infection that can be deadly. Governments have studied its use as a germ-warfare weapon. As a weapon, it would be released in the air. The disease occurs naturally after exposure to infected animals or insects, or contaminated water or food. There are different types of the disease, depending on where the exposure and symptoms occur:
causes tularemia. There are two strains of the bacteria. One causes infection more easily than the other. The bacteria are normally found in small animals, such as mice and rabbits. The germs can survive for weeks in a cool, moist environment. Naturally, people can catch the disease if bitten by an infected animal, tick, or deer fly. It can occur through contact with an infected animal's tissues or contaminated water, food, or soil. The bacteria also can enter the body through the lungs, the eyes, mucous membranes, or skin. People cannot pass the infection to other people.
A risk factor is something that increases your chance of getting a disease or condition. The main risk factor for tularemia is exposure to the bacteria from:
Hunting, trapping, or butchering infected animals
Working with infected animals or their tissue
Working in a laboratory with the bacteria
Eating meat from an infected animal
Being bitten by an infected mosquito or tick
Symptoms usually occur 3 to 5 days after exposure, but they can begin earlier or later. Symptoms vary depending on where the bacteria enter the body. Other factors include the amount of bacteria, its strength, and the ability of the person's immune system to fight the germs.
The doctor will ask about your symptoms, medical history and possible source of exposure, and perform a physical exam. Other cases in the area may alert healthcare workers of the possibility of a bioterrorism attack.
Examining body fluids using special techniques and precautions
Skin test to assess immune response
Culture of body fluids to check for bacteria
Blood test to detect antibodies to the bacteria
Antibiotics typically produce a quick response to the lung disease. The drugs are injected in a muscle or given through a vein. Later in treatment, some drugs can be given by mouth. Treatment lasts 10 to 14 days. Lymph nodes may require draining. Cases are reported to public health officials.
Streptomycin, with or without chloramphenicol
Quinolone antibiotics, such as Ciprofloxacin
Antibiotics may be ordered in the event of a terrorism exposure. People may be placed on a "fever watch," receiving drugs after developing a fever or flu-like symptoms. A vaccine exists to help prevent tularemia. It only is partially effective. The vaccine is not available in the US and not recommended for the general population. It is recommended for laboratory workers who are in regular, close contact with large quantities of the organism.
Measures to prevent the disease from natural causes include:
Do not handle sick or dead animals.
Wear gloves, mask, and goggles if skinning or butchering.
Completely cook game meats.
Wear protective clothing if in areas where ticks or deer flies live.
