A potentially fatal viral infection that attacks the central nervous system. Rabies is carried by wild animals (particularly bats and raccoons) and finds its way to humans by many routes. Most cases of rabies can be traced to animal bites, but cases have been documented in which the virus was inhaled in bat caves, contracted in lab accidents, or received from transplanted donor tissue. Symptoms include fever, aching muscles, and headache, potentially progressing to inflammation of the brain, confusion, seizures, paralysis, coma, and death. There is no cure for rabies after it has settled in the brain, so immediate emergency care for any suspicious animal contact is imperative. Rabies immunoglobulin shots, antibiotics, and rabies vaccine may be used immediately after contact with a suspected rabies carrier. To prevent rabies, pets should be vaccinated against the virus, and people should avoid contact with wild or unknown animals. A human rabies vaccine is available, but it is recommended only for those in high-risk occupations (such as game wardens, zookeepers, and animal control officers).
- Raccoon roundworm infection
Infection by the raccoon roundworm is also called Baylisascaris. The species commonly found in raccoonsis Baylisascaris procyonis. When infective eggs of this roundworm are ingested by humans, Baylisascaris larvae hatch in the intestine and travel through the organs and muscles. This is the larva migrans syndrome. Infected raccoons shed millions of eggs in their feces. […]
An ethnic stock or division of humans. Naturalists and ethnographers have long divided humans into a variable number of distinct races. However, DNA and other genetic studies have revealed that that most genetic variation, about 94%, is within so-called racial groups while these racial groupings differ from one another only in about 6% of their […]
- Race-based drug
A drug designed for a particular racial group. The first race-based drug was BiDil, a combination of two old drugs that increase levels of nitric oxide. BiDil was tested in African-Americans and reported in 2004 to reduce deaths from heart disease. The very concept of race-based therapy is highly controversial. While some black cardiologists hailed […]
