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....

A virus is a small infectious agent that replicates inside the living cells of organisms. It is a small infectious agent that can replicate only inside the living cells of organisms. Most are too small to be seen by anything but a microscope and they infect all organisms from animals to plants to bacteria. The first one discovered was the tobacco virus in 1898. Since then around 5,000 viruses...

Vaccinia virus (VACV or VV) is a large, complex, enveloped virus belonging to the poxvirus family. It is well-known for its role in eradicating smallpox. It was the first human disease to to successfully be eradicated by science. The World Health Organization was the one who completed the endeavor. The vaccinia virus saw renewed interest in the early 21st century due to concerns about the...

Simian immunodeficiency virus

Simian immunodeficiency virus (SIV), also known as African Green Monkey virus, is a retrovirus able to infect at least 33 species of African primates. SIV has been present in monkeys and apes for at least 32,000 years, probably longer. Strains from two of these primate species have crossed the barriers into humans resulting in HIV-2 and HIV-1. Contraction involves contact with the blood of...

Molluscum contagiosum
2011-02-23 17:00:17

The Molluscum contagiosum virus, MCV, is a virus, in the poxvirus family, that causes the disease Molluscum contagiosum in humans. The virions have a complex structure that is consistent with the structure of the poxvirus family. Since the virus cannot routinely be cultured diagnosis is made on the clinical appearance. It can be confirmed by excisional biopsy. There are four types of MCV...

Mumps Virus
2011-02-17 17:26:28

Mumps virus causes mumps which is a common childhood disease characterized by swelling of the parotid glands and other epithelial tissues causing high morbidity in some cases deafness. Infection is currently restricted to humans while the virus is transmitted by direct contact, droplet spread, or via contaminated objects. It is a vaccine preventable disease although significant outbreaks have...

Monkeypox virus causes monkeypox in both humans and animals. It was first found in 1958 in macaque monkeys that were being used as laboratory animals. The monkeys are often used for neurological experiments. The virus is typically found in rainforest regions of central and West Africa. It was first discovered in 1970 in humans and from 1970 to 1986 there were over 400 cases reported in...

Human immunodeficiency virus (HIV), a lentivirus, causes acquired immunodeficiency syndrome (AIDS) which is a condition in humans were the immune system begins to fail, leading to life-threatening opportunistic infections. Infection is transferred through bodily fluids where HIV is present as both free virus particles and within infected immune cells. The four most common routes of infection...

Herpes Simplex Virus 1 and 2
2011-01-20 19:35:34

Herpes simplex virus 1 and 2 (HSV-1 and HSV-2), are two members of the virus family Herpesviridae that infect humans. They are both ubiquitous and contagious and can spread when an infected person is producing and shedding the virus. Symptoms include watery blisters in the skin, mouth, lips, or genitals. Lesions usually heal with a scab characteristic of herpetic disease. HSV-1 and -2 remain...
