A study conducted in Sydney during the early epidemic stage of COVID-19 has found an association between lower humidity and an increase in locally acquired positive cases.

The research led by Professor Michael Ward, an epidemiologist in the Sydney School of Veterinary Science at the University of Sydney, and two researchers from our partner institution Fudan University School of Public Health in Shanghai, China, is the first peer-reviewed study of a relationship between climate and COVID-19 in the southern hemisphere.

Why humidity matter?

~ "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."

~ Studied 749 locally acquired cases of COVID-19 between February 26 and March 31. The team matched the patients' postcodes with the nearest weather observation station and studied the rainfall, temperature, and humidity for the period January to March 2020.

~ The study found lower humidity was associated with increased case notifications; a reduction in relative humidity of 1% was predicted to be associated with an increase of COVID-19 cases by 6 percent.

"This means we need to be careful coming into a dry winter," Professor Ward said.
