When the COVID-19 virus hit two years ago, AUB Associate Professor of pathology, virology and immunology Hassan Zaraket spiked to a new level of action. He adjusted his lab research -- on the genetic makeup of viruses and their spread, mutations, and vaccine responses -- to develop new diagnostic tests that can be used on the front line of public health action in Lebanon and across the region. He also shifted slowly to assess other respiratory transmissions, and the impact of masks and distancing. He talks about his research on infected patients and staff in the hospital emergency rooms, to determine the impact of more fresh air on the virus’ spread, and shares what he has learned about the best ways to reach the public with practical tips on staying healthy.
