How COVID-19 Spreads
The virus thought to spread mainly from person-to-person.
- Between people who are in close contact with one another (within about 6 feet)
- Via respiratory droplets produced when an infected person coughs or sneezes.
- These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
For confirmed coronavirus disease 2019 (COVID-19) cases, reported illnesses have ranged from mild symptoms to severe illness and death. Symptoms can include:
- Shortness of breath
Community Preparedness (non-pharmaceutical interventions)
- Voluntary Home Isolation: Stay home when you are sick with respiratory disease symptoms. At the present time, these symptoms are more likely due to influenza or other respiratory viruses than to COVID-19-related virus.
- Respiratory Etiquette: Cover coughs and sneezes with a tissue, then throw it in the trash can.
- Hand Hygiene: Wash hands often with soap and water for at least 20 seconds; especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing.
- If soap and water are not readily available, use an alcohol-based hand sanitizer with 60%-95% alcohol.
- Environmental Health Action: Routinely clean frequently touched surfaces and objects
Additional everyday preventive actions to help prevent the spread of respiratory diseases, including:
- Avoid close contact with people who are sick.
- Avoid touching your eyes, nose, and mouth.
- Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
- Follow CDC’s recommendations for using a face mask.
o CDC does not recommend that people who are well wear a face mask to protect themselves from respiratory diseases, including COVID-19.
o Face masks should be used by people who show symptoms of COVID-19 to help prevent the spread of the disease to others. The use of face masks is also crucial for health workers and people who are taking care of someone in close settings (at home or in a health care facility).
You can help yourself and your loved ones stay healthy by washing your hands often, especially during these key times when you are likely to get and spread germs:
- Before, during, and after preparing food
- Before eating food
- Before and after caring for someone at home who is sick with vomiting or diarrhea
- Before and after treating a cut or wound
- After using the toilet
- After changing diapers or cleaning up a child who has used the toilet
- After blowing your nose, coughing, or sneezing
- After touching an animal, animal feed, or animal waste
- After handling pet food or pet treats
- After touching garbage
Follow these five steps every time.
1. Wet your hands with clean, running water (warm or cold), turn off the tap, and apply soap.
2. Lather your hands by rubbing them together with the soap. Lather the backs of your hands, between your fingers, and under your nails.
3. Scrub your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.
4. Rinse your hands well under clean, running water.
5. Dry your hands using a clean towel or air dry them.
CDC Recommendations for COVID-19 Outbreaks in a Community
- Personal Protective Measures. During an outbreak in your community, CDC recommends the everyday preventive measures listed above—especially staying home when sick—and taking these additional measures:
o Keeping away from others who are sick.
o Limiting face-to-face contact with others as much as possible
o Consulting with your healthcare provider if you or your household members are at high risk for COVID-19 complications
o Wearing a face mask if advised to do so by your healthcare provider or by a public health official
o Staying home when a household member is sick with respiratory disease symptoms, if instructed to do so by public health officials or a health care provider (Voluntary Home Quarantine)
- Community Measures. If COVID-19 disease is occurring in your community, state and local public health authorities may decide to implement:
o Temporary closures or dismissals of childcare facilities and schools
o Other social distancing measures that increase the physical space between people, including:
o Workplace social distancing measures, such as replacing in-person meetings with teleworking
o Modifying, postponing, or cancelling mass gatherings.
Decisions about the implementation of community measures will be made by local and state officials, in consultation with federal officials as appropriate, and based on the scope of the outbreak and the severity of illness. Implementation will require extensive community engagement and ongoing and transparent public health communications.
