Why humidity matters
Professor Ward said there are biological reasons why humidity matters in transmission of airborne viruses.
"When the humidity is lower, the air is drier and it makes the aerosols smaller," he said. "When you sneeze and cough those smaller infectious aerosols can stay suspended in the air for longer. That increases the exposure for other people. When the air is humid and the aerosols are larger and heavier, they fall and hit surfaces quicker."

Specifically, differences in temperature and humidity affect how stable and transmissible viruses are. For instance, some data reviewed in the new paper suggest that cold, dry, unventilated air may contribute to the transmission of influenza in the winter.
