The Human Immunodeficiency Virus (HIV) can cause Acquired Immunodeficiency Syndrome (AIDS) and is typically spread by exposure to body fluids or tissue from an infected individual. Sex and injection drug use (IDU) are the most common ways of becoming infected with HIV. IDU, including use of opioids like heroin, can increase a person’s risk for HIV and Hepatitis C infections. Sharing injecting equipment with other persons can increase the risk of these infections. 

HIV Surveillance Program
Laboratories and medical providers report data on new and on-going HIV and hepatitis C to the Department of Health. These data are used to estimate the number of new diagnoses and the number of persons living with HIV disease in each county. The department of publishes an annual report that provides more detailed analyses of these data and produces custom data analyses upon request. Visit the HIV surveillance website to learn more about the program.
