[...] The Centers for Disease Control and Prevention (CDC) now says the novel virus "does not spread easily" from "touching surfaces or objects" -- but experts warn that doesn't mean it's no longer necessary to take "practical and realistic" precautions in stopping the spread of COVID-19.
Though it’s not exactly clear when, the federal health agency appears to have recently changed its guidelines from early March that simply said it "may be possible" to spread the virus from contaminated surfaces. The CDC now includes "surfaces or objects" under a section that details ways in which the coronavirus does not readily transmit.
COVID-19 is thought to spread mainly through close contact from person-to-person. Some people without symptoms may be able to spread the virus. We are still learning about how the virus spreads and the severity of illness it causes.
The virus is thought to spread mainly from person-to-person.
- Between people who are in close contact with one another (within about 6 feet).
- Through respiratory droplets produced when an infected person coughs, sneezes, or talks.
- These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
- COVID-19 may be spread by people who are not showing symptoms.
The virus spreads easily between people
How easily a virus spreads from person-to-person can vary. Some viruses are highly contagious, like measles, while other viruses do not spread as easily. Another factor is whether the spread is sustained, which means it goes from person-to-person without stopping.
The virus that causes COVID-19 is spreading very easily and sustainably between people. Information from the ongoing COVID-19 pandemic suggest that this virus is spreading more efficiently than influenza, but not as efficiently as measles, which is highly contagious.
The virus does not spread easily in other ways
COVID-19 is a new disease and we are still learning about how it spreads. It may be possible for COVID-19 to spread in other ways, but these are not thought to be the main ways the virus spreads.
- From touching surfaces or objects. It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes. This is not thought to be the main way the virus spreads, but we are still learning more about this virus.
- From animals to people. At this time, the risk of COVID-19 spreading from animals to people is considered to be low. Learn about COVID-19 and pets and other animals.
- From people to animals. It appears that the virus that causes COVID-19 can spread from people to animals in some situations. CDC is aware of a small number of pets worldwide, including cats and dogs, reported to be infected with the virus that causes COVID-19, mostly after close contact with people with COVID-19. Learn what you should do if you have pets.
Protect yourself and others
The best way to prevent illness is to avoid being exposed to this virus. You can take steps to slow the spread.
- Maintain good social distance (about 6 feet). This is very important in preventing the spread of COVID-19.
- Wash your hands often with soap and water. If soap and water are not available, use a hand sanitizer that contains at least 60% alcohol.
- Routinely clean and disinfect frequently touched surfaces.
It would be really nice if they could share the studies or data which made them change their position.
The question has been whether the virus is spreading predominantly through the air or through human contact and droplets. I guess now they're leaning towards the later.
