Most effective face-mask practices to reduce spread of infection of Covid-19: Study
ARLINGTON: A new study has provided guidance for increasing the effectiveness of face masks to reduce the spread of respiratory infectious pathogens including SARS-CoV-2. The research has been published in the 'American Journal of Infection Control'. Face masks are used to reduce the spread of infectious viruses such as SARS-CoV-2 that are transmitted by respiratory aerosols and droplets produced during activities such as talking, breathing and coughing. The US Centers for Disease Control and Prevention (CDC) recommended a mask that is multi-layered, covers the nose and mouth and forms a tight seal against the face. "The performance of face masks as devices that control infection spread depends upon both the ability of the mask material to filter aerosols and on how well the mask fits the wearer," said Francoise M. Blachere, MSc., Research Biologist, of the National Institute for Occupational Safety and Health (NIOSH), and the paper's lead author. Blachere and
