COVID-19 is a respiratory disease caused by the SARS-CoV-2 virus. It can spread from person to person through close contact (within about 6 feet) and respiratory droplets produced when an infected person coughs, sneezes, or talks. The virus can also be spread by touching surfaces or objects that have the virus on them and then touching your mouth, nose, or eyes.
The incubation period for COVID-19 is the time between when someone is infected with the virus and when they start showing symptoms. This period can range from 2 to 14 days, with an average of 5 days. During the incubation period, people can still be contagious and spread the virus to others, even if they don't have any symptoms.
In the sections below, we'll cover the main signs and symptoms of COVID-19, how long you're contagious and when you can stop isolating, and how to protect yourself and others from the virus.

Contagious during incubation
The incubation period for COVID-19 is the time between when someone is infected with the virus and when they start showing symptoms. This period can range from 2 to 14 days, with an average of 5 days.
- Infectious before symptoms:
During the incubation period, people can still be contagious and spread the virus to others, even if they don't have any symptoms.
- Most contagious:
People are most contagious 1-2 days before they start showing symptoms.
- Omicron variant:
The Omicron variant of COVID-19 is more contagious than previous variants, and people infected with Omicron may be contagious for a shorter period of time.
- Vaccinated people:
Vaccinated people are less likely to spread the virus to others, even if they are infected.
If you have been exposed to COVID-19, it is important to get tested and follow the recommended isolation guidelines, even if you don't have any symptoms. This will help to prevent you from spreading the virus to others.
Average 2-14 days
The incubation period for COVID-19, which is the time between exposure to the virus and the onset of symptoms, can vary from person to person. The average incubation period is 5 days, but it can range from 2 to 14 days.
This means that if you are exposed to COVID-19, you may not develop symptoms for up to 14 days. However, you can still be contagious during this time and spread the virus to others, even if you don't have any symptoms.
This is why it is important to get tested for COVID-19 if you have been exposed to the virus, even if you don't have any symptoms. If you test positive, you should isolate yourself from others to prevent spreading the virus.
The Omicron variant of COVID-19 has a shorter incubation period than previous variants. The average incubation period for Omicron is 3 days, and most people develop symptoms within 1-2 days of exposure.
If you have been exposed to COVID-19, it is important to monitor yourself for symptoms for 14 days. If you develop any symptoms, such as fever, cough, or shortness of breath, you should get tested for COVID-19 and isolate yourself from others.
Most contagious 1-2 days before symptoms
People infected with COVID-19 are most contagious 1-2 days before they start showing symptoms. This means that you can spread the virus to others before you even know you're sick.
- Viral load:
The amount of virus in a person's body is highest 1-2 days before symptoms appear. This is why people are most contagious during this time.
- Symptoms:
People with COVID-19 may experience a variety of symptoms, including fever, cough, shortness of breath, and loss of taste or smell. However, some people may have very mild symptoms or no symptoms at all.
- Omicron variant:
The Omicron variant of COVID-19 is more contagious than previous variants, and people infected with Omicron may be contagious for a shorter period of time.
- Vaccinated people:
Vaccinated people are less likely to spread the virus to others, even if they are infected.
If you have been exposed to COVID-19, it is important to get tested and follow the recommended isolation guidelines, even if you don't have any symptoms. This will help to prevent you from spreading the virus to others.
Can spread virus without symptoms
Asymptomatic transmission, or the spread of the virus by people who do not have any symptoms, is a major factor in the spread of COVID-19. It is estimated that up to 40% of people infected with COVID-19 may be asymptomatic.
- Silent spreaders:
People who are asymptomatic can still spread the virus to others, even if they don't know they're infected.
- High viral load:
Asymptomatic people may have high levels of virus in their respiratory tract, which means they can spread the virus just as easily as people who are showing symptoms.
- Omicron variant:
The Omicron variant of COVID-19 is more contagious than previous variants, and it is more likely to cause asymptomatic infections.
- Vaccinated people:
Vaccinated people are less likely to spread the virus to others, even if they are infected.
To prevent the spread of COVID-19, it is important to get vaccinated and boosted, wear a mask in indoor public spaces, and stay home if you are sick. Even if you don't have any symptoms, you could still be contagious and spread the virus to others.
Omicron variant more contagious
The Omicron variant of COVID-19 is more contagious than previous variants, and it is the dominant variant circulating globally. Omicron is more likely to cause breakthrough infections in vaccinated people, and it can also cause more severe illness in unvaccinated people.
One of the reasons why Omicron is more contagious is that it has a higher viral load than previous variants. This means that people infected with Omicron have more virus in their respiratory tract, which makes them more likely to spread it to others.
Omicron is also more transmissible because it is better able to evade the immune system. This means that even people who have been vaccinated or previously infected with COVID-19 can still get infected with Omicron.
The Omicron variant has a shorter incubation period than previous variants. The average incubation period for Omicron is 3 days, and most people develop symptoms within 1-2 days of exposure. This means that people infected with Omicron can spread the virus to others more quickly.
To protect yourself from Omicron, it is important to get vaccinated and boosted, wear a mask in indoor public spaces, and stay home if you are sick. Even if you have been vaccinated, you can still get infected with Omicron, so it is important to take precautions to protect yourself and others.
Vaccinated people less contagious
Vaccinated people are less contagious than unvaccinated people, even if they are infected with COVID-19.
- Reduced viral load:
Vaccinated people typically have lower levels of virus in their respiratory tract than unvaccinated people. This means that they are less likely to spread the virus to others.
- Shorter duration of illness:
Vaccinated people who do get infected with COVID-19 are likely to have a shorter duration of illness and be less likely to develop severe symptoms.
- Protection against variants:
Vaccines are effective against all variants of COVID-19, including Omicron. However, the Omicron variant is more likely to cause breakthrough infections in vaccinated people.
- Boosters:
Booster doses of the vaccine further reduce the risk of infection and severe illness. People who have been vaccinated and boosted are less likely to spread the virus to others.
Getting vaccinated and boosted is the best way to protect yourself from COVID-19 and to reduce the risk of spreading the virus to others. Vaccinated people are less likely to be hospitalized or die from COVID-19, and they are also less likely to spread the virus to others.
Isolation recommended for 5 days
If you test positive for COVID-19, the Centers for Disease Control and Prevention (CDC) recommends that you isolate for at least 5 days.
- Reduce transmission:
Isolation helps to prevent you from spreading the virus to others.
- Monitor symptoms:
Isolating allows you to monitor your symptoms and seek medical care if necessary.
- Protect high-risk individuals:
Isolation helps to protect people who are at high risk for severe illness from COVID-19, such as older adults and people with underlying medical conditions.
- End isolation safely:
After 5 days of isolation, if you have no symptoms or your symptoms are improving, you can end isolation. However, you should continue to wear a mask around others for an additional 5 days.
If you have symptoms of COVID-19, it is important to get tested and isolate yourself from others. Isolation can help to prevent the spread of the virus and protect others from getting sick.
Wear mask to protect others
Wearing a mask is one of the most effective ways to prevent the spread of COVID-19. Masks help to block respiratory droplets that contain the virus from being released into the air when you talk, cough, or sneeze.
Masks are especially important for people who are infected with COVID-19 but do not have any symptoms (asymptomatic people) or who have mild symptoms. These people may not know that they are infected and could spread the virus to others without realizing it. Wearing a mask can help to prevent this.
Masks are also important for people who have been vaccinated against COVID-19. While vaccines are very effective at preventing severe illness and death, they do not completely eliminate the risk of infection. Vaccinated people can still get infected with COVID-19 and spread the virus to others, although they are less likely to do so.
The best type of mask to wear is a well-fitting N95 or KN95 mask. These masks provide the highest level of protection against COVID-19. If you cannot wear an N95 or KN95 mask, a surgical mask or cloth mask is better than no mask at all.
Wearing a mask is a simple and effective way to protect yourself and others from COVID-19. Masks are especially important for people who are infected with COVID-19 or who have been exposed to the virus.
