What are the ways through which the COVID-19 (Coronavirus) Spread?
According to Centers for Disease Control and Prevention (CDC), the coronavirus can travel through the air at least 13 feet more than twice as far as social distancing guidelines. The world scientists are still learning about how the virus spreads and the severity of illness it causes. However the following are the ways through which coronavirus can be transmitted:
1. Person-to-person transmission of coronavirus
The virus is thought to spread mainly from person-to-person in the following ways:
- 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.
2. Transmission of coronavirus between people
- Some viruses are highly contagious, like measles, while other viruses do not spread as easily.
- The virus that causes COVID-19 is spreading very easily and sustainably between people.
- Information from the ongoing COVID-19 pandemic suggests that this virus is spreading more efficiently than influenza, but not as efficiently as measles, which is highly contagious.
- Generally, the more closely a person interacts with others and the longer that interaction, the higher the risk of COVID-19 spread.
3. Transmission of coronavirus from animals to people
- Some coronaviruses that infect animals can be spread to humans and then spread between people, but this is rare.
- This is what happened with the virus that caused the current outbreak of COVID-19, with the virus likely originating in bats.
- The first reported infections were linked to a live animal market, but the virus is now spreading from person to person.
4. Transmission of coronavirus from people to animals
- It appears that the virus that causes COVID-19 can spread from people to animalsin 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.
5. Transmission of coronavirus in other ways
- It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on itand 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 how this virus spreads.
Some FAQs on Coronavirus Spread
Can the virus that causes COVID-19 be spread through food, including restaurant take out, refrigerated or frozen packaged food?
Coronaviruses are generally thought to be spread from person to person through respiratory droplets. Currently, there is no evidence to support transmission of COVID-19 associated with food. Before preparing or eating food it is important to always wash your hands with soap and water for at least 20 seconds for general food safety.
Will warm weather stop the outbreak of COVID-19?
It is not yet known whether weather and temperature affect the spread of COVID-19. Some other viruses, like those that cause the common cold and flu, spread more during cold weather months but that does not mean it is impossible to become sick with these viruses during other months. There is much more to learn about the transmissibility, severity, and other features associated with COVID-19 and investigations are ongoing.
What is coronavirus community spread?
Community spread means people have been infected with the virus in an area, including some who are not sure how or where they became infected. Each health department determines community spread differently based on local conditions. For information on community spread in your area, please visit your health department’s website.
Can mosquitoes or ticks spread the virus that causes COVID-19?
At this time, CDC has no data to suggest that this new coronavirus or other similar coronaviruses are spread by mosquitoes or ticks. The main way that COVID-19 spreads is from person to person.
