This is a prospective observational study being conducted to learn about late (2+ weeks or more) effects of COVID-19 in people living with and without HIV. The investigators plan to do this by studying people who have COVID-19 and people who have not had COVID-19, and by studying people living with HIV and people who are HIV-negative. The investigators will investigate the average duration of symptoms after COVID-19, how these symptoms affect quality of life, and what medical complications are common after COVID-19 in people with and without HIV.
Participation involves:
* Participant completion of surveys about themselves, their health history, their quality of life and mood in the recent past, and about COVID-19 or HIV if the participant has a history of either infection. The investigators will ask participants to answer questions in up to 5 follow-up surveys over the course of a year about their symptoms, mood, quality of life, and changes in health. Participants will also complete a series of short tests of thinking, memory, and reaction speed at certain follow-up surveys.
* Up to two visits to the participant's home (or an acceptable location of their choosing) by a phlebotomist. The phlebotomist will collect about 3.5 tablespoons of blood, as well as measure height, weight, and vital signs when laying down and standing up.
This is a fully remote study and all study activities can be done from home or another location of the participant's choosing.
