"Masking and Ventilation Key in Preventing COVID-19: UCSD Study"
A UC San Diego-led study published in Clinical Infectious Diseases found that infection prevention measures such as universal masking and high ventilation standards were effective in preventing SARS-CoV-2 transmissions during the COVID-19 pandemic. The study used electronic health and contact tracing records to analyze virus transmission among patients and healthcare workers, revealing that personal protective equipment virtually eliminated healthcare-associated transmission. The study collected 12,933 virus samples and concluded that most transmissions occurred outside of healthcare settings, emphasizing the importance of universal masking and proper ventilation in preventing COVID-19 spread.
