He explained these surfaces include those touched very often, such as a door handle or touch screen. “Their size is on the order of width of human hair.” “The droplets could be expelled from mouth/nose in the event of coughing, sneezing, or even talking,” he said. “Motivated by ongoing COVID-19 pandemic, we conducted this research to understand the drying of respiratory droplets deposited on a surface because we know COVID-19 spreads through these droplets,” study author Rajneesh Bhardwaj, PhD, and associate professor at the Indian Institute of Technology in Mumbai, told Healthline. This was done in six cities worldwide under different weather conditions to understand which areas may be at highest risk. New research published June 8 in the Physics of Fluids journal examines the drying time of contaminated droplets on various surfaces. Risk is associated with droplet drying time While it seems clear that hot weather won’t stop the virus from spreading, new data finds it may help keep the virus from surviving for long periods of time on surfaces.Īn important factor in virus transmission is how long it takes a droplet to evaporate, because it can’t survive in a dry environment. Researchers have been wondering how a change in weather could affect the transmission of the virus. Research finds that those with the disease can even shed the virus when they defecate, meaning if someone doesn’t wash their hands thoroughly after a bathroom visit, they can also spread the virus to anything they touch. If a person with COVID-19 coughs or sneezes into their hand and then touches a doorknob, it means another person is at risk of developing the disease if they touch it. Smaller ones can remain suspended in the air. Just one cough could produce up to 3,000 of these droplets, which land on nearby surfaces and clothing. SARS-CoV-2, the virus which causes COVID-19, can be spread by tiny droplets expelled from a person’s mouth or nose with a cough or sneeze. The virus is most often spread via respiratory droplets but can also be spread via contaminated surfaces. With the spread of the virus that causes COVID-19, behaviors previously considered strange have become commonplace: opening doors with our elbows, office workers wiping their desks with disinfectant, and use of hand sanitizer that borders on obsessive.

Moisture-friendly surfaces, such as smartphone screens, cotton, and wood, should be cleaned more often than glass and steel surfaces since the droplets evaporate faster on these surfaces.Īll data and statistics are based on publicly available data at the time of publication.Higher temperatures can kill the virus more quickly. The likelihood of SARS-CoV-2 surviving on a surface increases roughly 5 times in a humid environment compared to a dry one.An important factor in virus transmission is how long it takes a droplet to evaporate because it can’t survive in a dry environment.Share on Pinterest Hot temperature may stop the novel coronavirus from surviving on surfaces.
