Rabies is a viral disease that causes encephalitis in humans and other mammals. [1] It was historically referred to as hydrophobia ("fear of water") because its victims would panic when offered liquids to drink. Early symptoms can include fever and abnormal sensations at the site of exposure. [1]
The prevalence of rabies, a deadly viral disease affecting mammals, varies significantly across regions worldwide, posing a persistent public health problem. Almost all human deaths caused by rabies occur in Asia and Africa. There are an estimated 59,000 human deaths annually from rabies worldwide. [1]
Rabies is present in humans in two separate stages, Dr. Drake Matuska, family physician at Mayo Clinic Health System in La Crosse, Wis., tells Yahoo Life. “Rabies does have an early-disease ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
Human and pet animal deaths from rabies virus infection have greatly reduced since the 1960s, when rabies was a more common cause of death in dogs.
3D still showing rabies virus structure. Rhabdoviruses have helical symmetry, so their infectious particles are approximately cylindrical in shape. They are characterized by an extremely broad host spectrum ranging from plants [citation needed] to insects [citation needed] and mammals; human-infecting viruses more commonly have icosahedral symmetry and take shapes approximating regular polyhedra.
That's not the case elsewhere, where exposure to rabid dogs is the cause of nearly all human rabies deaths worldwide, the CDC said. Protect your pet by: Keeping rabies vaccinations up to date.
Most cases of humans contracting rabies from infected animals are in developing nations. In 2010, an estimated 26,000 people died from the disease, down from 54,000 in 1990. [6] The World Health Organization (WHO) reports that dogs are the main source of human rabies deaths, contributing up to 99% of all transmissions of the disease to humans. [7]
