The rays of the sun they could kill quickly new coronavirus, according to a new study presented by the administration american this Thursday, that gives you hope about the possibility of the pandemic to slow down in the northern hemisphere during the summer months.
William Bryanadvisor on science and technology of the Department of Homeland Security United States, he said in the White House that the government scientists had proven the strong impact of ultraviolet rays on the coronavirus.
“Our observation most striking so far is the powerful effect that the sunlight seems to kill the virus, both on surfaces and in the air,” he explained during the daily briefing on the Covid-19.
“We have seen a similar effect both in temperature as in humidity. The rise of the temperatures or the humidity, or both, is generally less favorable for the virus.”

The scientists shuffled since the emergence of the novel coronavirus to the possibility of weakening with the temperature increase, that is to say, with the arrival of summer in the northern hemisphere.
Bryan showed a summary of the results of the experiment carried out at the National Center of Analysis and Countermeasures for Biodefense.
The study showed that, with a temperature of between 21 and 24 °C and a humidity of 20% in a non-porous surface, the virus takes 18 hours to be reduced by half.
This happened in six hours when the coronavirus was subjected to the same temperature, but with a humidity of 80%, and in just two minutes when we added the exposure to sunlight to the equation.
The scientists did the experiment to measure the impact of these variants on the virus in the air.
The pathogen in suspension in the air was reduced to half in an hour, with a temperature between 21 and 24 °C and a humidity of 20%. In the presence of sunlight, it hardly took a minute and a half to do so.
Bryan stated that the conditions of summer “will create an environment in which a transmission may go down.” But it warned that a lower spread does not mean that the pathogen will be completely eliminated and that the guidelines for social distancing will not be able to get up fully.
