Are HIV patients high risk for COVID19? Or do antiretrovirals have a protective effect?
gpt
HIV antiretrovirals only destroy retroviruses. COVID19 is a coronavirus therefore antiretroviral medications do NOT have a protective effect on COVID19. 

HIV patients do not have an increased risk for COVID19 if they are currently undetectable and have an acceptable/normal amount of CD4 cells.
