The coronavirus "does not spread easily" by touching surfaces or objects, said the US Centers for Disease Control and Prevention (CDC), changing its previous guidelines which placed a greater emphasis on this possibility.
Explaining the change, the official U.S. health agency clarified that "Covid-19 is a new disease and we are still learning more about this virus".More news: LG Q61 with 6.5-inch FHD+ Display, 48MP Quad Rear Cameras Launched
On Tuesday, health officials changed the guide to say the virus mainly spreads between people and does not spread easily in other ways.
However people should remain cautious as transmission from contaminated surfaces "may still be possible" as scientists work to discover more about how the virus spreads, the CDC warns. "This is not thought to be the main way the virus spreads, but we are still learning more about this virus", read the new guidelines.
Though information is limited at this time, the CDC warned that infants less than a year old "may be at higher risk for severe illness from COVID-19 compared with older children".More news: Coronavirus: No decision on fans at U.S. Open
"It also may help reduce anxiety and stress", he said.
Viral tests - commonly referred to as PCR tests as a lot of them use a process known as polymerase chain reaction - are used by health professionals to determine whether or not a person is now infected with the disease. Earlier this week, Columbia University researchers found that if the USA had implemented social distancing just two weeks earlier, then almost 1 million COVID-19 cases could have been prevented and more than 54,000 people would still be alive.
The CDC, however, continues to recommend that people clean and disinfect frequently touched surfaces daily, wear cloth face coverings in public, and practice social distance and frequent hand washing, among other safeguards, according to the agency's website. "But it does allow us to be practical and realistic as we try to return to a sense of normalcy", he added.More news: Joe Biden asks Amy Klobuchar to undergo VP vetting process, report says
"In a statement, CDC spokesperson Kristen Nordlund told The Hill that when the agency began to track coronavirus testing, viral tests were far more commonly used nationwide than serology testing".
