The Human Immunodeficiency Virus (HIV) is the virus responsible for causing Acquired Immunodeficiency Syndrome (AIDS). The HIV virus was originally identified on December 1st, 1981.
Statistics
The human immunodeficiency virus attacks and suppresses the immune system, reducing a person’s ability to fight infection. The virus specifically targets the cells crucial for fighting infection from pathogens. This allows diseases and infections to progress without resistance.
Within a few weeks of being infected with HIV, some people develop flu-like symptoms that last for a week or two, but others have no symptoms at all. People living with HIV may appear and feel healthy for several years. However, even if they feel healthy, HIV is still affecting their bodies. Untreated early HIV infection is also associated with many diseases including cardiovascular disease, kidney disease, liver disease, and cancer.
Scenario
Stacy is a police officer employed by the city of Denver, Colorado. She is regularly required to respond to emergency medical situations, often arriving before the local ambulance company. As a result, Stacy is frequently exposed to human blood.
Is Stacy likely to contract HIV from exposure to infected blood?
No. If Stacy follows universal precautions she is not likely to contract HIV. Universal precautions involve the use of protective barriers such as gloves, gowns, aprons, masks, or protective eyewear, which can reduce the risk of exposure of the first aid provider’s skin or mucous membranes to potentially infective materials.
