Strict adherence to public health measures effective in combating COVID-19

Until a vaccine is developed, public health measures are the best defense against SARS-CoV-2, the virus that causes COVID-19. These measures include masking, hand hygiene and physical distancing. \"Strict adherence to those things is a very powerful antidote to this virus,\" says Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic’s Vaccine Research Group.

On the Mayo Clinic Q&A podcast, Dr. Poland discusses the latest news on COVID-19, including what has been learned about herd immunity and contact tracing, as well as the effectiveness of different types of masks.
