Winter will worsen Coronavirus
Researchers said in most situations, respiratory droplets travel longer distances than the 6-foot social distance recommended.
The virus was found to be particularly persistent in cooler temperatures.
New research aims to help arm people with better knowledge of how SARS-CoV-2 spreads as the seasons change.
Winter is on its way. And in this year of coronavirus, comes the potential for a second wave of COVID-19. Add in flu season and our tendency to head inside and close our windows to the cold, wet weather, and it appears the next several months are going to present us with new health challenges.
The new study investigates the secret of this virus’s unusual success: its transmissibility, or how it manages to get from host to host. The dominant mode, it turns out, changes according to environmental conditions.
We found that in most situations, respiratory droplets travel longer distances than the 6-foot social distance recommended by the CDC,” Zhu says. This effect is increased in the cooler and more humid environments to distances of up to 6 meters (19.7 feet) before falling to the ground in places such as walk-in refrigerators and coolers, where temperatures are low and humidity is high to keep fresh meat and produce from losing water in storage.
In addition to its ability to travel farther, the virus is particularly persistent in cooler temperatures, remaining “infectious from several minutes to longer than a day in various environments,” according to several published studies.
