COVID-19 (coronavirus disease 2019) is a disease caused by a virus named SARS-CoV-2. It can be very contagious and spreads quickly. Over one million people have died from COVID-19 in the United States.
COVID-19 most often causes respiratory symptoms that can feel much like a cold, the flu, or pneumonia. COVID-19 may attack more than your lungs and respiratory system. Other parts of your body may also be affected by the disease. Most people with COVID-19 have mild symptoms, but some people become severely ill.
Some people including those with minor or no symptoms will develop Post-COVID Conditions – also called “Long COVID.”
COVID-19 SymptomsAbout Long COVID
COVID-19 spreads when an infected person breathes out droplets and very small particles that contain the virus. Other people can breathe in these droplets and particles, or these droplets and particles can land on their eyes, nose, or mouth. In some circumstances, these droplets may contaminate surfaces they touch.
Anyone infected with COVID-19 can spread it, even if they do NOT have symptoms.
The risk of animals spreading the virus that causes COVID-19 to people is low. The virus can spread from people to animals during close contact. People with suspected or confirmed COVID-19 should avoid contact with animals.
How COVID-19 Spreads
Antibodies are proteins your immune system makes to help fight infection and protect you from getting sick in the future. A positive antibody test result can help identify someone who has had COVID-19 in the past or has been vaccinated against COVID-19. Studies show that people who have antibodies from an infection with the virus that causes COVID-19 can improve their level of protection by getting vaccinated.
About Antibodies
There are many actions you can take to help protect you, your household, and your community from COVID-19. CDC’s COVID-19 hospital admission levels help individuals and communities decide when to take action to protect yourself and others based on the latest data and information from your area.
In addition to staying up to date with COVID-19 vaccines and basic health and hygiene practices like handwashing, CDC recommends some prevention actions at all COVID-19 hospital admission levels.
Some people are more likely than others to get very sick if they get COVID-19. This includes people who are older, are immunocompromised, have certain disabilities, or have underlying health conditions. Understanding your COVID-19 risk and the risks that might affect others can help you make decisions to protect yourself and others.
About Risk FactorsAbout Exposure Risks
Viruses are constantly changing, including the virus that causes COVID-19. These changes occur over time and can lead to new strains of the virus or variants of COVID-19 . Slowing the spread of the virus, by protecting yourself and others, can help slow new variants from developing. CDC is working with state and local public health officials to monitor the spread of all variants, including Omicron.
