HIV 101 & Ending the HIV Epidemic in the U.S.

Welcome to HIV 101 & Ending the HIV Epidemic in the U.S.

This training is a self-paced introduction to the basics of Human Immunodeficiency Virus (HIV); the content ranges from the biology of HIV to the current federal policies and programs in place to assist jurisdictions with their efforts to advance diagnosis, treatment, prevention, and response. The Population Health and Innovation team at ASTHO hopes this microlearning will be helpful to new members of the public health workforce and can serve as an accessible starting point for expanding knowledge of HIV, EHE, and the federal programs that exist to improve the lives of people living with HIV.
