The most commonly affected organs are the skin, eyes, lungs and lymph nodes but rarely internal organs may also be affected. Tularemia may lead to number of complications like inflammatory changes in the protective covering of the brain, the meninges (meningitis), lung tissue (pneumonia), protective covering of the heart, pericardium (pericarditis) and infection of the bone (osteomyelitis). The disease spread from mammals, birds, fish and contact with infected soil, water or dead animals.

What is rabies?

Rabies is a viral disease where the infecting rabies virus is transmitted to humans through bite of infected dogs. However, in the United States, the infection may spread by other animals like coyotes, raccoons, bat and skunks. The disease is almost always fatal after the appearance of symptoms.
