Yellow Fever
2011-03-04 17:38:30

Yellow fever is an acute viral hemorrhagic disease with a 40 to 50 nm enveloped RNA virus with positive sense of the Flaviviridae family. It is transmitted by the bite of female mosquitoes and is found in tropical and subtropical areas in South America and Africa, but not in Asia. Primates and a few kinds of mosquitoes are the only known hosts. The origin of the disease is most likely Africa....

West Nile virus (WNV) is a virus of the family Flaviviridae. It is part of the Japanese encephalitis antigenic complex of viruses and is found in both tropical and temperate regions. It primarily infects birds but can infect humans, horses, dogs, cats, bats, and other mammals. Humans are generally infected through the bites of mosquitoes and about 90% of West Nile Virus infections are without...

St. Louis Encephalitis is a disease caused by the Culex mosquito borne St. Louis Encephalitis virus. It is related to Japanese encephalitis virus and is a member of the Flaviviridae subgroup. It mainly affects the United States and occasionally hits Canada and Mexico. The name goes back to 1933 within five weeks in autumn an encephalitis epidemic of explosive proportions broke out in the...

Rotavirus is the most common cause of diarrhea among infants and young children and is one of several viruses that cause the stomach flu. It is in the family Reoviridae and is a genus of double-stranded RNA. Most children have been infected by the age of five. Each infection builds on previous immunity and thus subsequent infections are less severe and adults are rarely affected. The fives...

Rift Valley Fever

Rift Valley Fever (RVF) is a viral zoonosis that causes fever. It is spread through infected mosquitoes. It was first reported in 1915 in Kenya were it infected livestock. Outbreaks occur across sub-Saharan Africa, and in the "˜77-"˜78 outbreak several million people were infected and thousands died during a violent epidemic. In 1998 the virus killed 400 Kenyans and in 2000 an outbreak...

Respiratory syncytial virus

Respiratory syncytial virus (RSV) causes respiratory tract infections and is a major cause of lower respiratory tract infection and hospital visits during infancy and childhood. For premature infants and infants with congenital heart disease there is a prophylactic medication. During winter months in temperate climates there is an annual epidemic. Infection in tropical climates is most...

Rabies Virus
2011-02-23 17:45:51

The rabies virus is neurotropic virus, transmissible through the saliva of animals, that causes fatal disease in human and animals. Rabies is the type species of the Lyssavirus genus of Rhabdovirdae family. They are enveloped and single stranded RNA genome with negative-sense. All replication takes place in the cytoplasm. The virus has a bullet-like shape. Rabies enters the host cells through...

Poliovirus, the causative agent of poliomyelitis and a member of the family of Picornaviridae, is a human enterovirus. It is composed of an RNA genome that is a single-stranded positive-sense RNA. It was first isolate in 1909 and was published in 1981. It is one of the most well characterized viruses and has become a useful model system for understanding the biology of RNA viruses. It...

Cottontail Rabbit Papilloma Virus
2011-02-22 18:15:54

The cottontail rabbit papilloma virus (CRPV), is a type I virus under the Baltimore scheme and posses a non-segmented dsDNA genome. It infects rabbits by causing keratinous carcinomas usually near the animal's head. These tumors eventually interfere with the host's ability to eat and can lead to starvation. The virus provided the first mammalian model of a cancer caused by a virus. The name...

B19 Virus
2011-02-22 18:09:06

The B19 virus, referred to as parvovirus B19, was first known human virus in the family of parvovirus. It causes a childhood rash called fifth disease or commonly called slapped cheek syndrome. Discovered in 1975 by Yvonne Cossart, the virus gained its name because it was found in well B19 of a large series of Petri dishes. The virus is mainly spread through infected respiratory droplets....

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
