Human Immunodeficiency Virus (HIV)
| Morphology |
HIV is a member of the Retroviridae family, genus Lentivirus. Are double stranded DNA viruses enclosed within an icosahedral capsid. HIV is an
icosahedral, enveloped virus, of approximately 100 to 110 nm in diameter, and has
a single-stranded, linear, positive-sense RNA genome
|
|---|---|
| Disease |
HIV is the causative agent of AIDS. AIDS is characterized by symptoms and infections
caused by the breakdown of the immune system due to HIV infection. Due to immunodeficiency,
patients succumb to various fungi, parasites, bacteria, and/or viruses and are prone
to certain tumors.
|
| Zoonosis |
none.
|
| Host Range | Humans |
|---|---|
| Modes of Transmission |
Exposure of the virus to oral rectal, or vaginal mucosa during sexual activity. Transfusion
of contaminated blood products, using contaminated equipment during injection drug
use. Mother to infant during pregnancy.

| Signs and Symptoms |
