Measles, also known as Rubeola or Morbilli, is caused by a virus and infects the respiratory system. Morbilliviruses are enveloped, single-stranded, negative-sense RNA viruses. Symptoms include fever, cough, runny nose, red eyes and a generalized maculopapular erythematous rash. It is spread through respiration and is highly contagious. 90% of people without immunity who share a living...

2011-02-17 16:02:53

Lymphocytic choriomeningitis (LCM) is a viral disease, spread by rodents, that presents as aseptic meningitis, encephalitis, or meningoencephalitis. Lymphocytic Choriomeningitis Virus (LCMV) is the causative agent and is a member of the Arenaviridae family. The name is from the tendency of an individual to have high levels of lymphocytes during infection. It is spread by the common house...

Lassa Fever
2011-02-17 15:14:03

Lassa fever, first described in 1969 in Lassa, is an acute viral hemorrhagic fever. Clinical cases were known a decade before this but were not associated with this viral pathogen. It is endemic in West African countries and causes approximately 5,000 deaths. The Natal Multimammate Mouse is the primary animal host. The rodent is a source of protein but the virus is usually transmitted by...

Kaposi's sarcoma-associated herpesvirus (KSHV) one of seven currently known human cancer virus, is also the eighth human herpesvirus. Kaposi's sarcoma, caused by the virus, is common in AIDS patients, primary effusion lymphoma, and some types of multicentric Castelman's disease. Moritz Kaposi discovered the blood vessel tumor, in 1872, which would eventually be names Kaposi's sarcoma. It...

Influenza A Virus

Influenza A virus causes influenza in birds and some mammals. It is a genus of the Orthomyxoviridae family of viruses. Although the virus is uncommon several strains have been isolated from wild birds. Some can cause severe disease in domestic poultry and sometimes in humans. They are negative sense, single-stranded, segmented RNA viruses. Each subtype has mutated into a variety of strains with...

A human papillomavirus (HPV), a member of the papillomavirus family, is capable of infecting humans. HPVs establish productive infections in the skin or mucous membranes.

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...

Herpesviridae
2011-01-24 12:59:16

The Herpesviridae, a large family of DNA viruses, causes disease in animals and humans. Members of this family are known as herpesviruses. They all share a common structure where they are composed of relatively large double-stranded, linear DNA genomes encoding 100-200 genes encased within an icosahedral protein cage called the capsid. The whole particle is known as a virion. They are all...

Herpes Zoster
2011-01-24 12:56:26

Herpes zoster (or zoster), is known as shingles or zona and is a viral disease characterized by painful skin rash with blisters in a limited area on one side of the body.
