In countries where dogs commonly have the disease, more than 99% of rabies cases in humans are the direct result of dog bites. [11] In the Americas, bat bites are the most common source of rabies infections in humans, and less than 5% of cases are from dogs. [1] [11] Rodents are very rarely infected with rabies. [11]
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.
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]
Even in the U.S., there are approximately one to three human deaths annually from rabies. That number is so low because most possible or known rabies-exposure patients receive prophylactic ...
Rabies is a particular risk associated with dog bites. In the United States between 16,000 and 39,000 people come in contact with potentially rabid dogs and other animals and receive rabies pre-and post-exposure prophylaxis against the rabies virus each year. [25]
The woman, later identified as Leah Seneng, 60, marks the first human case of rabies in Fresno County since 1992. "In general, rabies is a disease that affects the brain, and it is very rare.
This can include people who are at a high risk of developing rabies because of their jobs or locations, such as those who: work with the rabies virus in laboratories have contact with bats
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]
