To Mask or Not to Mask...that is the Question! Do masks protect you against COVID-19 or not? Why are masks so controversial right now? When should you get tested? What about face shields? What about anti-body testing? Who can we trust for true information on what we should and shouldn't do? Is there a conspiracy? To get to the bottom of these questions, my guest is not only an MD who treats Covid-19 patients, Dr. Alya Khan also has a Master's degree in Environmental Toxicology AND is the Program Director of the Occupational Medicine Residency Program and Assistant Clinical Professor and UC Irvine.
