2019 Novel Coronavirus/COVID-19

Centers for Disease Control (CDC)

COVID-19 spreads very easily from person to person

How easily a virus spreads from person to person can vary. The virus that causes COVID-19 appears to spread more efficiently than influenza but not as efficiently as measles, which is among the most contagious viruses known to affect people.

COVID-19 most commonly spreads during close contact

  • People who are physically near (within 6 feet) a person with COVID-19 or have direct contact with that person are at greatest risk of infection.
  • When people with COVID-19 cough, sneeze, sing, talk, or breathe they produce respiratory droplets. These droplets can range in size from larger droplets (some of which are visible) to smaller droplets. Small droplets can also form particles when they dry very quickly in the airstream.
  • Infections occur mainly through exposure to respiratory droplets when a person is in close contact with someone who has COVID-19.
  • Respiratory droplets cause infection when they are inhaled or deposited on mucous membranes, such as those that line the inside of the nose and mouth.
  • As the respiratory droplets travel further from the person with COVID-19, the concentration of these droplets decreases. Larger droplets fall out of the air due to gravity. Smaller droplets and particles spread apart in the air.
  • With passing time, the amount of infectious virus in respiratory droplets also decreases.


COVID-19 can sometimes be spread by airborne transmission

  • Some infections can be spread by exposure to virus in small droplets and particles that can linger in the air for minutes to hours. These viruses may be able to infect people who are further than 6 feet away from the person who is infected or after that person has left the space.
  • This kind of spread is referred to as airborne transmission and is an important way that infections like tuberculosis, measles, and chicken pox are spread.
  • There is evidence that under certain conditions, people with COVID-19 seem to have infected others who were more than 6 feet away. These transmissions occurred within enclosed spaces that had inadequate ventilation. Sometimes the infected person was breathing heavily, for example while singing or exercising.
  • Under these circumstances, scientists believe that the amount of infectious smaller droplet and particles produced by the people with COVID-19 became concentrated enough to spread the virus to other people. The people who were infected were in the same space during the same time or shortly after the person with COVID-19 had left.
  • Available data indicate that it is much more common for the virus that causes COVID-19 to spread through close contact with a person who has COVID-19 than through airborne transmission. [1]

COVID-19 spreads less commonly through contact with contaminated surfaces

Respiratory droplets can also land on surfaces and objects. It is possible that a person could get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or eyes.
Spread from touching surfaces is not thought to be a common way that COVID-19 spreads

COVID-19 rarely spreads between people and 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.
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.

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.

  • Stay at least 6 feet away from others, whenever possible. This is very important in preventing the spread of COVID-19.
  • Cover your mouth and nose with a mask when around others. This helps reduce the risk of spread both by close contact and by airborne transmission.
  • 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.
  • Avoid crowded indoor spaces and ensure indoor spaces are properly ventilated by bringing in outdoor air as much as possible. In general, being outdoors and in spaces with good ventilation reduces the risk of exposure to infectious respiratory droplets.
  • Stay home and isolate from others when sick.
  • Routinely clean and disinfect frequently touched surfaces.

Symptoms

  • Anyone can have mild to severe symptoms.
  • Older adults and people who have severe underlying medical conditions like heart or lung disease or diabetes seem to be at higher risk for developing more serious complications from COVID-19 illness.


People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure to the virus. People with these symptoms may have COVID-19:

  • Fever or chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea

Take steps to protect yourself

Wash your hands often

Wash your hands often with soap and water for at least 20 seconds especially after you have been in a public place, or after blowing your nose, coughing, or sneezing.

It’s especially important to wash:

  • Before eating or preparing food
  • Before touching your face
  • After using the restroom
  • After leaving a public place
  • After blowing your nose, coughing, or sneezing
  • After handling your mask
  • After changing a diaper
  • After caring for someone sick
  • After touching animals or pets

If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them together until they feel dry.

Avoid touching your eyes, nose, and mouth with unwashed hands.

Avoid close contact

  • Inside your home: Avoid close contact with people who are sick. If possible, maintain 6 feet between the person who is sick and other household members.
  • Outside your home: Put 6 feet of distance between yourself and people who don’t live in your household. Remember that some people without symptoms may be able to spread virus. Stay at least 6 feet (about 2 arms’ length) from other people. Keeping distance from others is especially important for people who are at higher risk of getting very sick.

Cover your mouth and nose with a mask when around others

  • You could spread COVID-19 to others even if you do not feel sick.
  • The mask is meant to protect other people in case you are infected.
  • Everyone should wear a mask in public settings and when around people who don’t live in your household, especially when other social distancing measures are difficult to maintain.
  • Masks should not be placed on young children under age 2, anyone who has trouble breathing, or is unconscious, incapacitated or otherwise unable to remove the mask without assistance.
  • Do NOT use a mask meant for a healthcare worker. Currently, surgical masks and N95 respirators are critical supplies that should be reserved for healthcare workers and other first responders.
  • Continue to keep about 6 feet between yourself and others. The mask is not a substitute for social distancing.

Cover coughs and sneezes

  • Always cover your mouth and nose with a tissue when you cough or sneeze or use the inside of your elbow and do not spit.
  • Throw used tissues in the trash.
  • Immediately wash your hands with soap and water for at least 20 seconds. If soap and water are not readily available, clean your hands with a hand sanitizer that contains at least 60% alcohol.

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.
  • Then, use a household disinfectant. Most common EPA-registered household disinfectantsexternal icon will work.


Monitor Your Health Daily

  • Be alert for symptoms. Watch for fever, cough, shortness of breath, or other symptoms of COVID-19.
  • Especially important if you are running essential errands, going into the office or workplace, and in settings where it may be difficult to keep a physical distance of 6 feet.
  • Take your temperature if symptoms develop.
  • Don’t take your temperature within 30 minutes of exercising or after taking medications that could lower your temperature, like acetaminophen.

To disinfect:

Most common EPA-registered household disinfectants will work. Use disinfectants appropriate for the surface.

Options include:

  • Diluting your household bleach - To make a bleach solution, mix: 5 tablespoons (1/3rd cup) bleach per gallon of water OR 4 teaspoons bleach per quart of water
  • Follow manufacturer’s instructions for application and proper ventilation. Check to ensure the product is not past its expiration date. Never mix household bleach with ammonia or any other cleanser. Unexpired household bleach will be effective against coronaviruses when properly diluted.
  • Alcohol solutions - Ensure solution has at least 70% alcohol.
  • Other common EPA-registered household disinfectants - Products with EPA-approved emerging viral pathogens pdf icon[7 pages]external icon claims are expected to be effective against COVID-19 based on data for harder to kill viruses. Follow the manufacturer’s instructions for all cleaning and disinfection products (e.g., concentration, application method and contact time, etc.).

These are everyday habits that can help prevent the spread of several viruses. CDC does have specific guidance for travelers.

If you think you may have been exposed to a person with COVID-19, contact your healthcare provider.

  • Stay home and away from the people you live with as much as possible.
  • Consider getting tested.
  • Monitor your symptoms.
  • If you show an emergency warning sign, seek emergency medical care immediately. Call 911 or call ahead to your local emergency facility. Emergency warning signs include: Trouble breathing, Persistent pain or pressure in the chest, New confusion,Inability to wake or stay awake, or Bluish lips or face.
