An epidemic is the rapid spread of disease to a large number of people in a given population within a short period of time; in meningococcal infections , an attack rate in excess of 15 cases per 100,000 people for two consecutive weeks is considered ...
The mechanism of transmission of this disease starts with the injection of the parasite into the victim's blood when malaria-infected female Anopheles mosquitoes bite into a human being. The parasite uses human liver cells as hosts for maturation where it will continue to replicate and grow, moving into other areas of the body via the bloodstream.
The Florida panther had for a long time been considered a unique cougar subspecies, with the scientific name Felis concolor coryi proposed by Outram Bangs in 1899. [10] A genetic study of cougar mitochondrial DNA showed that many of the purported cougar subspecies described in the 19th century are too similar to be recognized as distinct. [11]
