35 percent of coronavirus patients could be asymptomatic, CDC says

The Centers for Disease Control and Prevention now advises that while it's possible to contract the coronavirus by touching a contaminated surface, that isn't "thought to be the main way the virus spreads".

Previously, the concern was that if an infected person coughed into their hand, then touched a surface, then you touched that surface, then touched your face, you could come down with COVID-19. The changed version says that it is not thought to be the main way through which the virus spreads. An individual does not need to feel sick or show symptoms to spread the submicroscopic virus.

"We are still learning about how the virus spreads and the severity of illness it causes", the CDC said.

"Transmission of SARS-CoV-2 to persons from surfaces contaminated with the virus has not been documented", the agency says on its page about disinfecting surfaces. "Our transmission language has not changed", Nordlund said, according to news reports. What the findings do emphasize is how critical it is to wear face masks, since some people who have COVID-19 may be asymptomatic.

The CDC recently updated their guidance on how researchers think the virus spreads in communities, and new information indicates it is not easily transmitted by touching surfaces.

We are not closing our borders. "We want to avoid a second wave and that is absolutely vital". Since the start of lockdown, air travel has been off the table unless it's essential travel.

Efforts to sanitize high-touch public surfaces, such as doorknobs and elevator buttons, should continue, Armitage said.

"Testing is recommended for all neonates born to women with confirmed or suspected COVID-19, regardless of whether there are signs of infection in the neonate", the federal health agency said in the guidelines released Wednesday.

Now, the Centers for Disease Control and Prevention estimates that more than a third of COVID-19 patients could be asymptomatic.

When the CDC revises its message, that isn't proof that science is untrustworthy, Armitage said.

The CDC clarified that it changed the site to improve its organization. During the pandemic's early days, people were told that non-medical masks weren't helpful. That's certainly still possible - just not the main way the virus is spreading.
