Although mass gatherings have been linked to a rise in transmission, research by retired virologists from the US army and US food and drug administration showed that sunlight quickly kills the virus, meaning people are likely to be safer outdoors. In fact, being indoors in lockdown may have been harmful for people, the study suggested.
During peak sunshine at the latitude of cities such as Cork - which occurs during the summer solstice around June 21 - just 30 minutes of sunlight is enough to reduce the infectivity of coronavirus by 90pc.
It means that even if someone was infected and coughed or sneezed onto an outdoor surface, the virus would be largely harmless within half an hour, with just a tiny viral load remaining.
The effect of sunlight on the virus is far greater at this time of the year. During the autumn equinox, on September 22, it would take an hour and 17 minutes to render the virus largely harmless in places such as Cork or London, and at the spring equinox, March 20, nearly three hours. At the December 21 winter solstice, the virus could survive for more than five hours in the weak sunlight, although indoors it is likely to last for days."
