HIV

Human Immunodeficiency Virus (HIV) is a virus that attacks the immune system causing the individual to be at risk for opportunity infections, or infections that come about because the immune system is weak. It is a slow progressive disease that is present throughout the body. Humans can get infected with HIV through contact with tissues, such as vaginal, anal area, mouth, eyes, or a break in the skin, such as a wound. It is diagnosed with blood tests and treated with a combination of drug therapies. There has been no cure found for HIV, so the person ends up dying from the virus in the long run.

The most common way HIV is spread is through sexual contact, needle sharing, and transmission from an infected mother to a baby through pregnancy, labor, or breastfeeding. It is spread by body secretions of an infected person to tissues of another person. When secretions of the infected person comes into contact with tissues in the vaginal, anal area, mouth, eyes, or cuts and punctures in the skin, such as wounds or needle holes, the virus is spread to the other person. HIV can also be spread through blood transfusions. HIV is present in blood, semen, vaginal fluid, injections, and breast milk as free virus particles and virus within infected immune cells.

HIV comes in three stages. The initial stage starts within weeks of contact. It often comes with flu like symptoms of body aches, fever, fatigue, headache, swelling of the lymph nodes, and runny nose. After an infected person overcomes these symptoms, they go through the second stage, which is a long duration period of eight to ten years with no symptoms at all.

The second stage is called the asymptomatic period.
