How the Coronavirus is spread
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)
- 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.
Spread from contact with infected surfaces or objects
It may be possible that a person can get Coronavirus by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.
When does spread happen?
- People are thought to be most contagious when they are most symptomatic (the sickest).
- Some spread might be possible before people show symptoms; there have been reports of this with this new Coronavirus, but this is not thought to be the main way the virus spreads.
How efficiently does the virus spread?
How easily a virus spreads from person-to-person can vary. Some viruses are highly contagious (like measles), while other viruses are less so. Another factor is whether the spread continues over multiple generations of people (if spread is sustained). The virus that causes Coronavirus seems to be spreading easily and sustainably in Hubei province and other parts of China. In the United States, spread from person-to-person has occurred only among a few close contacts and has not spread any further to date.
There is still more to be learned
Coronavirus is an emerging disease and there is more to learn about its transmissibility, severity, and other features and what will happen in the United States. New information will further inform the risk assessment.
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
CDC believes at this time that symptoms of Coronavirus may appear in as few as 2 days or as long as 14 days after exposure. This is based on what has been seen previously as the incubation period of MERS-CoV viruses.
There is currently no vaccine to prevent Coronavirus disease 2019 (COVID-19). The best way to prevent illness is to avoid being exposed to this virus. However, as a reminder, CDC always recommends 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.
- Stay home when you are sick.
- Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
- Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
- Follow CDC’s recommendations for using a facemask.
- CDC does not recommend that people who are well wear a facemask to protect themselves from respiratory diseases, including COVID-19.
- Facemasks should be used by people who show symptoms of Coronavirus to help prevent the spread of the disease to others. The use of facemasks 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).
- Wash your 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 at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.

For information specific to healthcare, see CDC’s Hand Hygiene in Healthcare Settings
These are everyday habits that can help prevent the spread of several viruses. CDC does have specific guidance for travelers.
- While the immediate risk of this new virus to the American public is believed to be low at this time, everyone can do their part to help us respond to this emerging public health threat:
- It’s currently flu and respiratory disease season and CDC recommends getting a flu vaccine, taking everyday preventive actions to help stop the spread of germs, and taking flu antivirals if prescribed.
- If you are a healthcare provider, be on the look-out for people who recently traveled from China and have fever and respiratory symptoms.
- If you are a healthcare provider caring for a Coronavirus patient or a public health responder, please take care of yourself and follow recommended infection control procedures.
- If you have been in China or have been exposed to someone sick with Coronavirus in the last 14 days, you will face some limitations on your movement and activity. Please follow instructions during this time. Your cooperation is integral to the ongoing public health response to try to slow spread of this virus. If you develop Coronavirus symptoms, contact your healthcare provider, and tell them about your symptoms and your travel or exposure to a Coronavirus patient.
- For people who are ill with COVID-19, please follow CDC guidance on how to reduce the risk of spreading your illness to others.
Steps to help prevent the spread of Coronavirus if you are sick
If you are sick with Coronavirus or suspect you are infected with the virus that causes the Coronavirus, follow the steps below to help prevent the disease from spreading to people in your home and community.
Stay home except to get medical care
You should restrict activities outside your home, except for getting medical care. Do not go to work, school, or public areas. Avoid using public transportation, ride-sharing, or taxis.
Separate yourself from other people and animals in your home
People: As much as possible, you should stay in a specific room and away from other people in your home. Also, you should use a separate bathroom, if available.
Animals: Do not handle pets or other animals while sick. See Coronavirus and Animals for more information.
Call ahead before visiting your doctor
If you have a medical appointment, call the healthcare provider and tell them that you have or may have Coronavirus infection. This will help the healthcare provider’s office take steps to keep other people from getting infected or exposed.
Wear a facemask
You should wear a facemask when you are around other people (e.g., sharing a room or vehicle) or pets and before you enter a healthcare provider’s office. If you are not able to wear a facemask (for example, because it causes trouble breathing), then people who live with you should not stay in the same room with you, or they should wear a facemask if they enter your room.
Cover your coughs and sneezes
Cover your mouth and nose with a tissue when you cough or sneeze. Throw used tissues in a lined trash can; immediately wash your hands with soap and water for at least 20 seconds or clean your hands with an alcohol-based hand sanitizer that contains 60 to 95% alcohol, covering all surfaces of your hands and rubbing them together until they feel dry. Soap and water should be used preferentially if hands are visibly dirty.
Clean your hands often
Wash your hands often with soap and water for at least 20 seconds or clean your hands with an alcohol-based hand sanitizer that contains 60 to 95% alcohol, covering all surfaces of your hands and rubbing them together until they feel dry. Soap and water should be used preferentially if hands are visibly dirty. Avoid touching your eyes, nose, and mouth with unwashed hands.
Avoid sharing personal household items
You should not share dishes, drinking glasses, cups, eating utensils, towels, or bedding with other people or pets in your home. After using these items, they should be washed thoroughly with soap and water.
Clean all “high-touch” surfaces everyday
High touch surfaces include counters, tabletops, doorknobs, bathroom fixtures, toilets, phones, keyboards, tablets, and bedside tables, every day. Also, clean any surfaces that may have blood, stool, or body fluids on them. Use a household cleaning spray or wipe, according to the label instructions. Labels contain instructions for safe and effective use of the cleaning product including precautions you should take when applying the product, such as wearing gloves and making sure you have good ventilation during use of the product.
Monitor your symptoms
Seek prompt medical attention if your illness is worsening (e.g., difficulty breathing). Before seeking care, call your healthcare provider and tell them that you have, or are being evaluated for, COVID-19. Put on a facemask before you enter the facility. These steps will help the healthcare provider’s office to keep other people in the office or waiting room from getting infected or exposed. Ask your healthcare provider to call the local or state health department. Persons who are placed under active monitoring or facilitated self-monitoring should follow instructions provided by their local health department or occupational health professionals, as appropriate.
If you have a medical emergency and need to call 911, notify the dispatch personnel that you have, or are being evaluated for COVID-19. If possible, put on a facemask before emergency medical services arrive.
Discontinuing home isolation
Patients with confirmed Coronavirus should remain under home isolation precautions until the risk of secondary transmission to others is thought to be low. The decision to discontinue home isolation precautions should be made on a case-by-case basis, in consultation with healthcare providers and state and local health departments.
