Keep cleaning surfaces, but coronavirus mainly spreads person-to-person — CDC

To perform the role of protection, said the CDC, capable even a piece of old clothing that you want to cover your mouth and nose.

'This is not thought to be the main way the virus spreads, but we are still learning more about this virus'.

Aside from contaminated surfaces, other low-risk ways of spreading the coronavirus are from animals to people, and people to animals, the CDC said. This can be especially problematic as many cities and states are still lacking in widespread COVID-19 testing capabilities.

"Environmental health and rodent control programs may see an increase in service requests related to rodents and reports of unusual or aggressive rodent behavior", the CDC wrote on its website.

Early in the COVID-19 pandemic, public health experts emphasized curtailing transmission of the virus from surfaces, said Dr. Keith Armitage, medical director of the University Hospitals Roe Green Center for Travel Medicine & Global Health.

Linsey Marr, an aerosol scientist at Virginia Tech told New York Times that the coronavirus spreads more readily than when people get into close contact and also in places with poor ventilation.

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. This news is on rounds, but much relief can be found only when people know how it doesn't spread so easily. Close contact means within about 6 feet, the distance at which a sneeze flings heavy droplets.

"Direct contact with people has the highest likelihood of getting infected - being close to an infected person, rather than accepting a newspaper or a FedEx guy dropping off a box", said virologist Vincent Munster, a researcher at the Virus Ecology Section of Rocky Mountain Laboratories, the National Institute of Allergy and Infectious Diseases facility in Hamilton, Montana.

The CDC clarified that it changed the site to improve its organization. "Our transmission language has not changed", Nordlund said, according to news reports.
