Molecular HIV surveillance

Did you know that molecular HIV surveillance (MHS) is the collection of HIV genetic data used to support local and state health departments in monitoring trends in HIV transmission and drug resistance? Learn more about MHS and how health departments and CDC use this data to guide HIV prevention efforts.


What is MHS?

Curious about molecular HIV surveillance? Download 10 Molecular HIV Surveillance FAQs, a plain-language document that explains what MHS is and how it is used by health departments to identify transmission patterns and detect HIV drug resistance.


What can we learn from MHS data?

Colin Flynn, ScM, the Chief of the Center for HIV Surveillance, Epidemiology and Evaluation at the Maryland Department of Health explains what we can learn from MHS data.


How do health departments use MHS data to guide prevention efforts?

Learn NYC's strategy to end the HIV epidemic and how it is using MHS data to respond to HIV clusters and guide prevention efforts. Download the NYC Strategy to Ending the HIV Epidemic and Using Molecular HIV Surveillance Data to Guide Public Health Practice in NYC presentations. Also, download overview from the District of Columbia and learn how they collect data, investigate clusters, and partner with Maryland and Virginia to improve the public’s health.


How do health departments communicate MHS data to their communities?

As MHS evolves, the Houston Health Department is committed to moving forward in a thoughtful and meaningful way with strategic partners and community members. To learn how they use MHS data to response to HIV clusters and foster community engagement, download the health department's presentation slideshealth advisory from the Texas Department of State Health Services, community invitation from the mayor of Houston, MHS genotype cluster talking points referenced in Houston's Molecular HIV Surveillance Cluster Response and Community Engagement presentation.
