COVID-19 disease COVID-19 is an infectious disease. The disease is caused by a coronavirus not found in people before. As doctors and scientists continue to gather new information, it is important to take COVID-19 seriously. We do not yet know all of the negative effects it may have. It is important to keep working to slow the spread of the virus by staying home when you can, staying 6 feet away from others, wearing a mask, covering your coughs and sneezes, and washing your hands often and well. For more information on symptoms, see CDC: Symptoms of Coronavirus. We are still learning more about the new virus and will share new information when we have it.

Coronavirus Disease 2019 (COVID-19) Key Messages Basic overview of COVID-19 in multiple languages.

Symptoms Symptoms of COVID-19 can include fever, cough, shortness of breath, chills, headache, muscle pain, sore throat, fatigue, congestion, or loss of taste or smell. Other less common symptoms include gastrointestinal symptoms like nausea, vomiting, or diarrhea. These symptoms may appear 2-14 days after you are exposed to the virus that causes COVID-19. Not everyone with COVID-19 has all of these symptoms, and some people may not have any symptoms. Even after recovering from COVID-19, some people may have lingering symptoms such as fatigue, cough, or joint pain. The long-term health effects are still unknown but there may be permanent damage to the heart, lungs, or other organs. This is more likely in those who had more severe illness but may also be possible even in those who had mild illness. Talk to your health care provider if you have questions or concerns about symptoms. How it spreads People can spread the COVID-19 disease to each other. The disease spreads by droplets or aerosols (tiny particles) from the nose and mouth when someone who is infected coughs, sneezes, or exhales. The most common way COVID-19 spreads is through close contact. When people are close to each other, the droplets can land in the mouths or noses of people nearby. It may be possible for people to breathe the droplets into their lungs. It is important to stay at least 6 feet away from other people in public. At home, someone who is sick should stay alone and in one room as much as possible. COVID-19 can also sometimes spread through airborne transmission. This means that aerosols (small droplets or particles) can sometimes linger in the air for minutes to hours, and may be able to infect people who are further than 6 feet from the person with COVID-19 or after they have left the room. Airborne transmission of COVID-19 is more likely to happen in indoor spaces without good ventilation, or when the infected person was breathing heavily, like when singing or exercising. It is possible that COVID-19 can spread when droplets land on surfaces and objects that other people then touch, though this is not thought to be a common way that it spreads. It is important to wash your hands before you touch your mouth, nose, face, or eyes. Clean surfaces that are touched often, especially if someone in the house is sick. Infected people may be able to spread the disease before they have symptoms or feel sick. A person can also spread the disease if they have no symptoms. Research has shown that around 40-50% of people infected do not develop symptoms. For more information, see CDC: How COVID-19 Spreads.

Viruses constantly change through mutation, and new variants of a virus are expected to occur over time. Multiple COVID-19 variants are circulating globally. Variants first detected in the United Kingdom (UK), Brazil, and South Africa have been detected in the United States. The UK and Brazil variants have been identified in Minnesota. MDH and our partners are actively testing new positive test samples to continue to detect variants and learn more. Early indications are that the new variants may spread more easily, but there is no sign yet that they are any different in terms of how sick people can get and how they affect any particular person. Continue to take steps to prevent the spread of COVID-19. It is important to wear a mask, stay 6 feet from others, avoid gatherings, wash your hands often, and stay home if you feel sick or have been in close contact with someone who has COVID-19. We will continue to give updates as we learn more. For more information, visit CDC: New COVID-19 Variants.

Severity Many people with COVID-19 have mild illness. However, anyone can become severely ill from this virus. Risk for severe illness increases with age. For example, people in their 50s are at higher risk for severe illness than people in their 40s. Similarly, people in their 60s or 70s are, in general, at higher risk for severe illness than people in their 50s. The greatest risk for severe illness from COVID-19 is among people 85 or older. People of any age who have underlying medical conditions may have a greater risk of getting very sick from COVID-19. See CDC: People at Increased Risk for guidance on which underlying medical conditions put people at an increased risk or who should be extra careful. Ask your health care provider if you have greater risk of getting sicker from COVID-19.

For more information, see COVID-19 Vaccine. Most people with COVID-19 have mild symptoms and are often able to recover at home with rest, liquids, and over the counter medication.

Physical health effects The virus that causes COVID-19 can affect people in different ways. Some can get very sick, while most have mild or moderate symptoms and get better without going to a clinic or into a hospital. Some have no symptoms. Some people die. Some people are in the hospital for weeks. Some may need to be put on a ventilator in order to breathe and survive. Some may need to be put on a heart-lung bypass machine. The virus that causes COVID-19 has been linked to increased: Blood clotting Strokes Heart damage Other organ damage The long-term health effects are still unknown but there may be permanent damage to the heart, lungs, or other organs. This is more likely in those who had more severe illness but may also be possible even in those who had mild illness. New evidence shows that COVID-19 can also lead to health problems in children. More research is needed to better understand how the virus may cause short and long-term illness. See CDC: Long-Term Effects of COVID-19 for more information.
