It appears that the novel coronavirus can’t survive for a long time on items such as door handles and other nonporous surfaces when it’s under the condition of under sunlight, higher temperature and humidity, said a U.S official on Thursdays in a potential sign that the pandemic could become weaker during the summertime.
A strong statement comes from the U.S. government researchers found that virus multiplies best indoors and in dry conditions, and loses potency when temperatures and humidity rise, especially under sunlight, claimed Bill Bryan, acting head of the U.S. Department of Homeland Security’s Science and Technology Directorate.
“The virus is dying at a much more rapid pace”, Bryan told a White House news briefing. “The virus dies quickest in the presence of direct sunlight,”
President Donald Trump has previously expressed interest in whether summer weather would end the outbreak of the virus, suggesting in February that warmer spring temperatures could eliminate cases by this month.
Bryan suggested the new U.S. research offered practical tips for many Americans, including “increasing the temperature and humidity for potentially contaminated indoor spaces” to kill the virus on surfaces. At a temperature of 70 to 75 degrees Fahrenheit and 80% humidity in the summer sun, for example, the research showed the virus would last just two minutes on a porous surface. Dry environments Bryan said, may require “extra care.”
“Suppose we hit the body with a tremendous ultraviolet or just very powerful light,” Trump said, following Bryan’s presentation. “I think that hasn’t been checked but you’re going to test it.”
Researchers could also bring “the light inside the body,” Trump said, “either through the skin or in some other way.”
The World Health Organization has given some warning against using UV lamps to sterilize any part of the body, saying it can cause skin irritation.
Bryan also said that research had shown bleach could kill the virus in saliva or respiratory fluids in five minutes and isopropyl alcohol could kill it even more quickly. More testings are suggested, too.
Also, the U.S.president stated that social distancing might still need to be maintained until early summer, despite some states were showing signs of progress.
More than 874,000 people in the United States are known to have been infected and over 49,600 have died of COVID-19, the highly contagious respiratory illness caused by the novel coronavirus, according to a Reuters tally.
