COVID-19 is a disease caused by SARS-CoV-2 that can trigger what doctors call a respiratory tract infection. It can affect your upper respiratory tract (sinuses, nose, and throat) or lower respiratory tract (windpipe and lungs).
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.
▪️ Shortness of breath or difficulty breathing.
▪️ Muscle or body aches.
▪️ New loss of taste or smell.
▪️ Sore throat.
▪️ Congestion or runny nose.
▪️ Nausea or vomiting.
This list does not include all possible symptoms. CDC will continue to update this list as we learn more about COVID-19.
If someone is showing any of these signs, seek emergency medical care immediately:
▪️ Trouble breathing.
▪️ Persistent pain or pressure in the chest.
▪️ New confusion.
▪️ Inability to wake or stay awake.
▪️ Pale, gray, or blue-colored skin, lips, or nail beds, depending on skin tone.
This list is not all possible symptoms.
If you’re infected, symptoms can show up in as few as 2 days or as many as 14. It varies from person to person.
According to researchers in China, these were the most common symptoms among people who had COVID-19:
Lack of appetite 40%.
Body aches 35%.
Shortness of breath 31%.
Some people who are hospitalized for COVID-19 have also have dangerous blood clots, including in their legs, lungs, and arteries.
How do I know if it’s COVID-19, a cold, or the flu?
Symptoms of COVID-19 can be similar to a bad cold or the flu. Your doctor will suspect COVID-19 if:
You have a fever and a cough.
You have been exposed to people who have it within the last 14 days.
Coronavirus Risk Factors.
Anyone can get COVID-19, and most infections are mild. The older you are, the higher your risk of severe illness.
You also a have higher chance of serious illness if you have one of these health conditions:
1. Chronic kidney disease.
2. Chronic obstructive pulmonary disease (COPD). A weakened immune system because of an organ transplant.
4. Serious heart conditions such as heart failure or coronary artery disease.
5. Sickle cell disease.
6. Type 2 diabetes.
7. Moderate to severe asthma.
8. Diseases that affect your blood vessels and blood flow to your brain.
9. Cystic fibrosis.
10. High blood pressure.
11. A weakened immune system because of a blood or bone marrow transplant, HIV, or medications like corticosteroids.
13. Liver disease.
15. Damaged or scarred lung tissue (pulmonary fibrosis).
18. Type 1 diabetes.
How does the coronavirus spread?
SARS-CoV-2, the virus, mainly spreads from person to person.
Most of the time, it spreads when a sick person coughs or sneezes. They can spray droplets as far as 6 feet away. If you breathe them in or swallow them, the virus can get into your body. Some people who have the virus don’t have symptoms, but they can still spread the virus.
You can also get the virus from touching a surface or object the virus is on, then touching your mouth, nose, or possibly your eyes. Most viruses can live for several hours on a surface that they land on.
A study shows that SARS-CoV-2 can last for several hours on various types of surfaces:
Copper: 4 hours.
Cardboard: up to 24 hours.
Plastic or stainless steel: 2 to 3 days.
That’s why it’s important to disinfect surfaces to get rid of the virus.
Some dogs and cats have tested positive for the virus. A few have shown signs of illness. There’s no evidence that humans can catch this coronavirus from an animal, but it appears it can be passed from humans to animals.
