Human Immunodeficiency Virus (HIV)

HIV is the virus that gradually weakens the immune system of the infected person, leaving that person unable to fight off other infections. This leads to acquired immunodeficiency syndrome (AIDS) and will ultimately cause death.

HIV-infected persons may have no symptoms or may experience symptoms such as swollen lymph nodes, fatigue, weight loss, diarrhea, persistent dry cough and fever.

HIV & AIDS Trends

According to CDC statistics, HIV-related illness was the sixth leading cause of death among young adults between the ages of 25 and 44 years old in 2007. It is still the sixth leading cause of death for this age group today.

HIV Model

In 2009, CDC reported that new HIV infections are stable at about 50,000 a year. However, the rate of new cases in younger men is increasing.

Medical advances

Medical advances have been made in recent years regarding HIV treatment. Several antiviral drugs, called protease inhibitors, have been found to slow the replication of the virus, but this is NOT a cure.

A protocol has been developed by the Public Health Service (PHS) for administering a series of drugs after a high-risk exposure to a known HIV-infected source. The series of drugs is expected to reduce the likelihood that the exposed person will become HIV-infected. This protocol has been adopted by LBNL as well as by many healthcare facilities nationwide.

Occupational Exposure

Healthcare workers are generally considered to have the highest risk of having an occupational exposure to blood or other potentially infectious materials.

To date, a total of 57 healthcare worker exposures resulting in sero-conversion (the worker became infected with HIV) have been reported to CDC.

Picture

The majority of these cases were suspected to be the result of needle stick accidents or exposures through a break in the skin.  The body fluid involved in the majority of these cases was human blood.
