⚠ Data for the years 2021 & 2022 are preliminary. Due to the impact of the COVID-19 pandemic, data for the year 2020 should be interpreted with caution.

COVID-19 disruptions in HIV diagnosis, care and reporting of deaths during 2020 have also made incidence, prevalence, and knowledge of status estimates derived from a CD4-based model, unreliable. Therefore, a 2020 edition of the HIV Surveillance Supplemental Report “Estimated HIV Incidence and Prevalence in the U.S.”, which provides data on estimated incidence, prevalence, and knowledge of status in the U.S., was not published by CDC.

Viral Suppression

If taken as prescribed, HIV medicine reduces the amount of HIV in the body (viral load) to a very low level, which keeps the immune system working and prevents illness. This is called viral suppression—defined as having less than 200 copies of HIV per milliliter of blood.
