Study says longer hours of Sunlight linked to higher Coronavirus incidence

While higher humidity and heat may slow the spread of Coronavirus, longer hours of sunlight linked to higher incidents of the cases, according to study.

The research published in the journal Geographical Analysis, indicates that sunny days tempt more people out even if this means higher risk of COVID-19 infection.

The outcomes by researchers led by McMaster University in Canada inform the widespread scientific debate over how seasonal changes, basically warmer weather, might shape the spread of Coronavirus.

While researchers has shown that pathogens such as SARS CoV 2 and influenza thrive in humidity and lower temperatures, little is known about SARS-CoV-2, the virus that causes COVID-19, the researchers said.

There is a huge pressure to reopen the economy, and many people want to know if it will be safer to do so in the summer months, they said.

Restriction in movement, which have begun to ease around the globe, hinge in part on how Coronavirus will be affected by a change in season, said Antonio Paez, a professor at McMaster, and lead author of the study.

Paez and colleagues investigated climate factors in the spread of Coronavirus in several provinces in Spain, one among the countries hardest hit by the COVID-19 pandemic, with more than 270,000 cases.

They combined and analysed data on reported cases of the Coronavirus cases and meterological information over a period of 30 days that begun immediately before a state of emergency was declared.

At excessive levels of heat and humidity, scientists discovered that for every % increase, there was a 3% decline in the incidence of COVID-19, possibly because warmer temperature curtail the viability of COVID-19.

The opposite was true for hours of sunshine; more sun meant greater spread of Coronavirus, they said.

The researchers speculate the increase may be related to human behaviour, since compliance with lockdown measures breaks down in summer days.
