A Professor of Medicine in residence at the University of California, San Francisco, Steven Deeks M.D., is an expert on HIV-associated immune dysfunction. Using his 30 years of experience researching viral illness, Deeks has turned his hand to the study of the long term impacts of COVID-19 on our immune systems.  The parallels that he draws between HIV and Long Covid are startling.  Studying a community cohort for the past two years, Deeks believes that we are beginning to unravel the mechanisms of Long Covid, and there is hope that some of these are treatable.
