New research adds to the growing body of evidence that low humidity, dry air can increase the risk of Covid-19 virus.

The study, published in the journal Transboundary and Emerging Diseases, focused on the Greater Sydney area during the early epidemic stage of Covid-19 found an association between lower humidity and an increase in community transmission.

"This second study adds to a growing body of evidence that humidity is a key factor in the spread of Covid-19," said study researcher Michael Ward from the University of Sydney in Australia.

The estimate is about a 2-fold increase in Covid-19 notifications for a 10 per cent drop in relative humidity.

According to the researchers, dry air appears to favour the spread of Covid-19, meaning time and place become important.

Accumulating evidence shows that climate is a factor in Covid-19 spread, raising the prospect of seasonal disease outbreaks.
