Climate is the key reason why surface-based infections of COVID-19 are far more likely in some cities than others.
TUESDAY, June 9, 2020 (HealthDay News) -- When someone infected with the new coronavirus talks, coughs or sneezes, tiny droplets containing virus land on surfaces nearby.
If touched by someone else, those contaminated surfaces are a means of COVID-19 transmission. But new research shows that surface-based infections are far more likely in some cities than others.
Climate is the key, according to researchers from the Indian Institute of Technology Bombay, in Mumbai, India. They discovered that in cities with cooler but more humid weather, viral-laden droplets on surfaces linger longer before drying out, greatly upping the odds that the virus within them stays alive and contagious.
