Tularemia could be a rare and extremely communicable disease caused by Francisella tularensis microorganism. It's additionally known as zoonotic disease or cervid fly fever. The microorganism will infect a large variety of animals, as well as rabbits and hares, beavers, muskrats, squirrels, and mice, and transmit the sickness to folks. Cases of tularaemia have occurred in social unit pets, like dogs, cats, and hamsters.

Their square measures few reportable cases of tularaemia within the US (about one hundred to two hundred cases reportable per year), and it's thought-about a rare sickness. However, some cases are also misdiagnosed or go unreported as a result of the symptoms of the sickness given those of alternative diseases. A majority of the confirmed cases have occurred in rural components of Arkansas, Kansas, Missouri, and OK. folks of all ages will become infected, though males square measure at higher risk than females.

Wild animals often die once being infected, however those who receive prompt treatment will get over zoonosis. Someone infected with zoonosis cannot pass the infection on to a different person. However, F. tularensis microorganism square measure terribly infectious and might survive for long periods within the surroundings.

Tularemia does not occur naturally in humans and is not famous to pass from person to person. However, zoonosis happens worldwide, particularly in rural areas, as a result of several mammals, birds and insects square measure infected with F. tularensis. The organism will live for weeks in soil, water and dead animals.

  • Insect bites. Although a variety of insects carry deer fly fever, ticks and cervid flies are presumably to transmit the malady to humans. Tick bites cause an oversized share of cases of ulceroglandular deer fly fever. 

  • Exposure to sick or dead animals. Ulceroglandular deer fly fever can even result from handling or being bitten by an infected animal, most frequently a rabbit or hare. bacteria enter the skin through little cuts and abrasions or a bite, associated ulceration forms at the wound web site.

  • Infection around the brain and spinal cord (meningitis). Meningitis could be a serious and typically grave infection of the fluid and membranes (meninges) close to the brain and neural structure. 

  • Irritation around the heart (pericarditis). This is swelling and irritation of the thin membrane that surrounds the heart (pericardium).
