While you have symptoms, and for up to 10 days since symptoms began, keep your distance from others, including people at high risk of severe disease.
You can also spread COVID-19 in the 48 hours before your symptoms start. If you never have symptoms, consider yourself most infectious in the 5 days after you test positive.
You may be infectious for up to 10 days. You are most infectious in the 2 days before your symptoms start and while you have acute symptoms (such as a runny nose, sore throat, fever, cough). Some people with COVID-19 do not develop symptoms at all but are still able to infect others.
In high-risk settings, they may be considered infectious from 72 hours before symptoms start. People with mild illness are generally considered recovered after 7 days if they have been asymptomatic or have not developed any new symptoms during this time.
You are contagious for the entire period of time symptoms are present, all the way until they disappear.
Your infectiousness is highest 1 day before the start of your symptoms and begins to wane about a week later for most people. The Omicron variant has a shorter incubation period, compared to other variants. For the Omicron variant, the incubation period is 1 to 4 days.
You can spread the common cold from a few days before your symptoms appear until all of the symptoms are gone. Most people will be contagious for up to 2 weeks. Symptoms are usually worse during the first 2 to 3 days, and this is when you're most likely to spread the virus.
How long do omicron symptoms last? Most people who test positive with any variant of COVID-19 typically experience some symptoms for a couple weeks. People who have long COVID-19 symptoms can experience health problems for four or more weeks after first being infected, according to the CDC.
You're generally contagious with a cold 1-2 days before your symptoms start, and you could be contagious as long as your symptoms are present—in rare cases, up to 2 weeks. The contagious period for the flu can last as long as 5-7 days from when you first felt sick.
A person may have mild symptoms for about one week, then worsen rapidly. Let your doctor know if your symptoms quickly worsen over a short period of time.
Gradually build up exercise – seize the time when you are feeling less tired and go for a short walk – but you MUST still avoid any contact with others. However, at this stage lookout for breath related symptoms (see below what to look for).
Once you have had COVID-19, your immune system responds in several ways. This immune response can protect you against another infection for several months, but this protection decreases over time.
When do omicron subvariant symptoms start? The time it takes for an infected person to develop symptoms after an exposure is shorter for the omicron variant than for previous variants — from a full week down to as little as three days or less, according to the Centers for Disease Control and Prevention.
While you may not see any symptoms, you may still be contagious. Understanding your infection and its contagious period will help you and others stay healthy.
Cold-related coughs can last for up to eight weeks. The good news is that you're typically only contagious for the first three to five days of the initial respiratory infection, says Dr. Buhr. A lingering cough will usually clear up on its own as postnasal drip improves and inflammation decreases.
If you test positive for COVID-19 and have no symptoms – you may end after day 5. If you test positive for COVID-19 and have symptoms – you may end after day 5 if: You are fever-free for 24 hours (without the use of fever-reducing medication) Your symptoms are improving.
In infected individuals, the peak viral load occurred on day 5, with the virus first detected in the throat and then rising to significantly higher levels in the nose.
No, long COVID cannot be passed from one person to another. Having long COVID does not mean that you are still contagious.
Colds are most contagious in the first 2 to 4 days after symptoms start. But they can spread up to a few weeks after that. Your symptoms will usually show up 2 to 3 days after you've been infected, so you may not know you're sick when you first get the virus.
What's smartest is to stay home for the worst of the illness-about two to four days for a severe cold and five to seven days for the flu, Saxinger said. "When you're feeling your worst, try not to be out and about; that's when you are most infectious."
Within 7–10 days , people will usually start to recover from a cold. Symptoms begin to ease up, and people will start feeling better. People may also find that they have more energy and are more able to carry out tasks as usual.

Fever or chills. Cough. Shortness of breath or difficulty breathing. Fatigue.
An incubation period is the number of days between when you were first infected by a virus and when you first see symptoms appear. During this time, the individual, even with no signs or symptoms, could carry the virus and pass it on to others.
