Social Distancing but not the Environmental factors can control spreading of Covid-19:

According to a Canadian study, researchers compared the
number of confirmed cases of COVID-19 in the United
States, Canada and other countries on March 20 and
again on March 27, to determine the effect of latitude,
temperature, humidity, school closures, restrictions of
mass gatherings, and social distancing on the spread
of the disease. They looked at a total of more than
375,600 confirmed COVID-19 cases.
The results showed little or no association between
latitude or temperature with a rise in COVID-19 cases
and a weak association between humidity and fewer cases.
But school closures, social distancing and restrictions
of large gatherings have helped control cases,
according to the researchers.
