Surgical masks may help prevent infected people from making others sick with seasonal viruses, including coronaviruses, according to new research that could help settle a fierce debate spanning clinical and cultural norms.

A new publication in PLoS Pathogens by an international team of investigators shows that flu virus might spread via air rather than through contact and large droplet spray, as commonly thought. A large part of the evidence about how respiratory illnesses like COVID-19 are transmitted comes from research on influenza. These new data provide more support for the recommendation by scientists that we include precautions against airborne spread of Covid-19 to have an impact on slowing infection rates.

Staying active can help older people prevent depression while following the COVID-19 social distancing guidelines, according to a new University of Maryland School of Public Health study published in the American Journal of Geriatric Psychiatry.

Climate change affects the timing of spring and is leading to an increase in asthma hospitalizations , according to a new study led by Amir Sapkota of the University of Maryland School of Public Health. The study, published in the Journal of the American Medical Association (JAMA), is the first to provide quantitative data on the connection between climate change, changes in plant phenology and asthma hospitalizations.

Plant phenology is the study of periodic plant cycles and how seasonal and yearly variations in climate influence them.
