Tularemia is an acute natural focal disease of a person with multiple pathways of infection, food, contact, air-dust, vector-borne. Tularemia is characterized by many symptoms, fever, lymph node damage and others.
Tularemia, description, symptoms, first aid and treatment methods, prevention.
More than 40 species of animals living in the northern hemisphere are susceptible to tularemia. Infection of animals in nature (the circulation of an infectious agent) occurs as a result of biting blood-sucking arthropods, eating corpses of sick animals, and drinking contaminated water. Human infection can occur by contact during the shooting of skins of commercial rodents.
Tularemia, infection, symptoms, course and stages of the disease in humans, prevention.
The contact pathway of infection with tularemia is the main one for hunters. Infection occurs when skinning muskrat and other species of near-water commercial rodents and insectivores. Possible infection by eating insufficiently thermally processed meat of sick hares.
At the site of penetration of the microbe into the human body, a primary inflammatory focus is formed in the form of a skin ulcer, conjunctivitis, bronchitis or pneumonia. Then, during the development of the disease, inflammation of the lymph nodes occurs with the formation of external or internal buboes. Intensive bacterial reproduction occurs in them..
This reproduction leads to damage to many organs and tissues. The incubation period lasts 3-7 days. Tularemia begins suddenly with a sharp rise in temperature. Recovery is slow, relapses and various complications are possible. Sick people are not dangerous to others.
There is a specific live tularemia vaccine. The vaccine is produced by the smallpox method. Full immunity develops 20-30 days after vaccination. Revaccination is carried out after 5 years. All rural residents in intensive foci and hunters involved in the fishing of water rats and muskrats are subject to vaccination..
Hunters during epilepsy of tularemia are not recommended to get commercial rodents. In some cases, hunting may be prohibited. In the case of the extraction of animal skins, it is necessary to dry it outside for at least 45 days. You can not enter them in the room, as well as feed the carcasses of rodents to domestic animals. When exporting skins from areas where an epizootic of tularemia is noted, they must be treated with chloropicrin.
