What is coronavirus disease 2019 (COVID-19)?
Coronavirus disease 2019 (COVID-19) is a respiratory illness that can spread from person to person. The virus that causes COVID-19 is a novel coronavirus that was first identified during an investigation into an outbreak in Wuhan, China.
How many cases of COVID-19 have been reported in the U.S.?
The first case of COVID-19 in the United States was reported on January 21, 2020. The current count of cases of COVID-19 in the United States is available on CDC’s webpage at https://www.cdc.gov/coronavirus/2019-ncov/cases-in-us.html
How does COVID-19 spread?
Person-to-person 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).
- Through 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.
Can someone spread the virus without being sick?
- 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 occurring with this new coronavirus, but this is not thought to be the main way the virus spreads.
Spread from contact with contaminated 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, but this is not thought to be the main way the virus spreads.
How easily the virus spreads
How easily a virus spreads from person-to-person can vary. Some viruses are highly contagious (spread easily), like measles, while other viruses do not spread as easily. Another factor is whether the spread is sustained, spreading continually without stopping.
The virus that causes COVID-19 seems to be spreading easily and sustainably in the community (“community spread”) in some affected geographic areas.
What are the symptoms of COVID-19?
Reported illnesses have ranged from mild symptoms to severe illness and death for confirmed coronavirus disease 2019 (COVID-19) cases.
These symptoms may appear 2-14 days after exposure (based on the incubation period of MERS-CoV viruses).
- Fever
- Cough
- Shortness of breath
If you develop emergency warning signs for COVID-19 get medical attention immediately. Emergency warning signs include*:
- Trouble breathing
- Persistent pain or pressure in the chest
- New confusion or inability to arouse
- Bluish lips or face
*This list is not all inclusive. Please consult your medical provider for any other symptoms that are severe or concerning.
What are severe complications from this virus?
Some patients have pneumonia in both lungs, multi-organ failure and in some cases death.
What should I do if I recently traveled from an area with ongoing spread of COVID-19?
If you have traveled from an affected area, there may be restrictions on your movements for up to 2 weeks. If you develop symptoms during that period (fever, cough, trouble breathing), seek medical advice. Call the office of your health care provider before you go, and tell them about your travel and your symptoms. They will give you instructions on how to get care without exposing other people to your illness. While sick, avoid contact with people, don’t go out and delay any travel to reduce the possibility of spreading illness to others.
Is there a vaccine?
There is currently no vaccine to protect against COVID-19. The best way to prevent infection is to take everyday preventive actions, like avoiding close contact with people who are sick and washing your hands often.
Is there a treatment?
There is no specific antiviral treatment for COVID-19. People with COVID-19 can seek medical care to help relieve symptoms.
What to do if you are sick with coronavirus disease 2019 (COVID-19)
If you are sick with COVID-19 or suspect you are infected with the virus that causes COVID-19, 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
- Stay home: People who are mildly ill with COVID-19 are able to recover at home. Do not leave, except to get medical care. Do not visit public areas.
- Stay in touch with your doctor. Call before you get medical care. Be sure to get care if you feel worse or you think it is an emergency.
- Avoid public transportation: Avoid using public transportation, ride-sharing, or taxis.
Separate yourself from other people and animals in your home
- Stay away from others: As much as possible, you should stay in a specific “sick room” and away from other people in your home. Use a separate bathroom, if available.
- Limit contact with pets and animals: You should restrict contact with pets and other animals, just like you would around other people.
- Although there have not been reports of pets or other animals becoming sick with COVID-19, it is still recommended that people with the virus limit contact with animals until more information is known.
- When possible, have another member of your household care for your animals while you are sick with COVID-19. If you must care for your pet or be around animals while you are sick, wash your hands before and after you interact with them. See COVID-19 and Animals for more information.
Call ahead before visiting your doctor
If you have a medical appointment, call your doctor’s office or emergency department, and tell them you have or may have COVID-19. This will help the office protect themselves and other patients.
Wear a facemask
- If you are sick: You should wear a facemask when you are around other people and before you enter a healthcare provider’s office.
- If you are caring for others: If the person who is sick is not able to wear a facemask (for example, because it causes trouble breathing), then people who live in the home should stay in a different room. When caregivers enter the room of the sick person, they should wear a facemask. Visitors, other than caregivers, are not recommended.
Cover coughs and sneezes
- Cover: Cover your mouth and nose with a tissue when you cough or sneeze.
- Dispose: Throw used tissues in a lined trash can.
- Wash hands: Immediately wash your hands with soap and water for at least 20 seconds. If soap and water are not available, clean your hands with an alcohol-based hand sanitizer that contains at least 60% alcohol.
Avoid sharing personal household items
- Do not share: Do not share dishes, drinking glasses, cups, eating utensils, towels, or bedding with other people in your home.
- Wash thoroughly after use: After using these items, wash them thoroughly with soap and water or put in the dishwasher.
Clean your hands often
- Wash hands: Wash your hands often with soap and water for at least 20 seconds. This is especially important after blowing your nose, coughing, or sneezing; going to the bathroom; and before eating or preparing food.
- Hand sanitizer: If soap and water are not available, use an alcohol-based hand sanitizer with at least 60% alcohol, covering all surfaces of your hands and rubbing them together until they feel dry.
- Soap and water: Soap and water are the best option, especially if hands are visibly dirty.
- Avoid touching: Avoid touching your eyes, nose, and mouth with unwashed hands.
Avoid close contact
Clean and disinfect
- Clean AND disinfect frequently touched surfaces daily. This includes tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks.
- If surfaces are dirty, clean them: Use detergent or soap and water prior to disinfection.
To disinfect:
Most common EPA-registered household disinfectants will work. Use disinfectants appropriate for the surface.
Options include:
Monitor your symptoms
- Seek medical attention, but call first: Seek medical care right away if your illness is worsening (for example, if you have difficulty breathing).
- Call your doctor before going in: Before going to the doctor’s office or emergency room, call ahead and tell them your symptoms. They will tell you what to do.
- Wear a facemask: If possible, put on a facemask before you enter the building. If you can’t put on a facemask, try to keep a safe distance from other people (at least 6 feet away). This will help protect the people in the office or waiting room.
- Follow care instructions from your healthcare provider and local health department: Your local health authorities will give instructions on checking your symptoms and reporting information.
If you develop emergency warning signs for COVID-19 get medical attention immediately. Emergency warning signs include*:
- Difficulty breathing or shortness of breath
- Persistent pain or pressure in the chest
- New confusion or inability to arouse
- Bluish lips or face
*This list is not all inclusive. Please consult your medical provider for any other symptoms that are severe or concerning.
Call 911 if you have a medical emergency: If you have a medical emergency and need to call 911, notify the operator that you have or think you might have, COVID-19. If possible, put on a facemask before medical help arrives.
Discontinuing home isolation
- People with COVID-19 who have stayed home (home isolated) can stop home isolation under the following conditions:
- If you will not have a test to determine if you are still contagious, you can leave home after these three things have happened:
- You have had no fever for at least 72 hours (that is three full days of no fever without the use medicine that reduces fevers)
AND - other symptoms have improved (for example, when your cough or shortness of breath have improved)
AND - at least 7 days have passed since your symptoms first appeared
- If you will be tested to determine if you are still contagious, you can leave home after these three things have happened:
- You no longer have a fever (without the use medicine that reduces fevers)
AND - other symptoms have improved (for example, when your cough or shortness of breath have improved)
AND - you received two negative tests in a row, 24 hours apart. Your doctor will follow CDC guidelines.
In all cases, follow the guidance of your healthcare provider and local health department. The decision to stop home isolation should be made in consultation with your healthcare provider and state and local health departments. Local decisions depend on local circumstances.
