Can people be immune to COVID?

During the first wave of the pandemic, prior to vaccines, Swadling and other researchers in the U.K. studied a group of health-care workers whose bodies were able to fight SARS-CoV-2 without creating specific antibodies to do so. This means they were able to fend off the virus before ever testing positive.

Should I isolate and get tested if I have recovered from COVID-19 but I have symptoms again?

If a previously infected person experiences new symptoms consistent with COVID-19 3 months or more after the date of the previous illness onset (or date of last positive viral diagnostic test [RT-PCR or antigen test] if the person never experienced symptoms), the person should undergo repeat viral diagnostic testing. However, serologic testing should not be used to establish the presence or absence of SARS-COV-2 infection or reinfection. These people who have a positive test result should be considered infectious and remain isolated until they again meet criteria for discontinuation of isolation or of transmission-based precautions. Contact tracing during the person’s second episode of symptoms is warranted.

Can Vitamin D help treat COVID-19?

There is evidence that vitamin D may enhance immune functions in human cells and reduce the spread of some viruses in the laboratory setting. However, there is very limited information about the safety and effectiveness of using vitamin D for treating or preventing COVID-19 (as of August 7, 2020)(source). If your healthcare professional finds that you have a Vitamin D deficiency, it should be treated regardless of COVID-19. The best way to learn how to treat COVID-19 is to conduct randomized controlled clinical trials.
