How long is covid-19 contagious and when are you most contagious

The UK may have reached the peak of the recent wave of Covid-19 infections caused by the BA.2 Omicron sub-variant – but the virus has not gone away.

The country has largely returned to normalcy. Restrictions have been lifted, self-isolation is no longer mandatory – although it is still recommended – and the government has abolished the provision of free COVID testing.

But in the week to April 27 more than 120,000 people reported testing positive, and more than 2,000 died of the virus.

Especially now that restrictions are in place, it is as important as ever for people to recognize when they have had the virus and take steps to reduce transmission to others.

Here are the symptoms of Covid, when you are most contagious and what to do if you have the virus.

What are the symptoms of Covid-19?

The NHS now lists the following as official COVID symptoms:

  • high temperature or shivering (chills) – a high temperature means you feel hot to touch on your chest or back (you do not need to measure your temperature)
  • new, persistent cough – this means a cough that lasts for more than an hour, or three or more coughing episodes in 24 hours
  • decrease or change in your sense of smell or taste
  • shortness of breath
  • feeling tired or exhausted
  • aching body
  • Headache
  • sore throat
  • blocked or runny nose
  • loss of appetite
  • Diarrhea
  • feeling sick or being sick

The NHS says the symptoms are “similar to symptoms of other diseases, such as colds and flu”.

When are you most contagious?

For previous variants like Delta, the World Health Organization said symptoms could begin to develop anywhere between two days and two weeks after infection.

However, the incubation period for Omicron and its branches is believed to be very short – between three and five days.

People are thought to be most contagious for one to two days before the onset of symptoms, and during the two to three days after.

This helps explain why Omicron has spread so quickly, because people have already passed on the virus before realizing it.

Harvard University states: “People are thought to be most contagious early in their illness.

“With Omicron, most transmission occurs one to two days before the onset of symptoms and two to three days after. People without symptoms can also spread the coronavirus to others.”

Health Secretary Sajid Javid said in December: “A recent analysis by the UK Health Protection Agency suggests that the window between infection and infectivity may be smaller for the Omicron version than for the Delta version.”

Data shows that most people are not contagious after seven days of experiencing symptoms or testing positive for the first time, especially when vaccinated, and the vast majority are no longer contagious after 10 days.

More COVID-19

How long does covid last?

The NHS says most people with COVID-19 will or will feel better within a few weeks.

For many people, especially those who have been fully vaccinated and have received a booster, it will be just a few days.

However, data from the Zo COVID study, which has been researching the virus since the start of the pandemic, suggests that one in 10 people may still have symptoms after three weeks, and may suffer for a few months.

The study said, “Our research shows that some people have fatigue, headache, cough, anosmia (loss of smell), sore throat, delirium tremens more than three weeks after first reporting symptoms to the app. And experiencing chest pain.”

What about the long covid?

Some people will experience what is known as a prolonged covid – symptoms that persist for months after the initial infection.

According to data from the Office for National Statistics (ONS), 3-5 percent of people affected by Kovid have symptoms for more than 12 weeks that affect their daily lives.

The NHS says the likelihood of having long-term symptoms does not seem to be linked to how sick you are when you first get the virus.

Symptoms of prolonged covid include:

  • extreme tiredness (fatigue)
  • shortness of breath
  • chest pain or tightness
  • Problems with memory and concentration (“brain fog”)
  • difficulty sleeping (insomnia)
  • heart palpitation
  • dizzy
  • pins and needles
  • joint pain
  • depression and anxiety
  • tinnitus, earache
  • feeling sick, diarrhea, stomach pain, loss of appetite
  • a high temperature, cough, headache, sore throat, change in sense of smell or taste
  • rashes

If you continue to experience symptoms several weeks after you first tested positive for COVID-19, contact a GP.

People with prolonged covid will not be contagious any longer than usual, so you don’t need to worry about infecting others after 10 days.

The World Health Organization (WHO) defines prolonged covid as a syndrome that occurs in individuals with a history of probable or confirmed SARS-CoV-2 infection, usually after three months of onset of covid-19 with symptoms. Occurs together that lasts at least two. months and cannot be explained by alternative diagnoses.

Zoe data shows that thorough vaccination halves the risk of developing chronic covid.

Professor Tim Spector, lead scientist of the Zoe study, said: “Everyone experiences illness in their own way, and it is certainly no different in a longer COVID.”

When will you stop testing positive?

Most people will stop testing positive within 10 days of starting to experience symptoms or receiving their first positive test.

However, it is possible to continue testing positive for weeks or even months after having the virus.

The good news is that even if you are still testing positive after a long time, it is not because you are actually contagious.

Gavi Vaccine Alliance explains: “The time it takes to test negative after contracting COVID-19 depends on the severity of the case, and also on the test. PCR tests that hunt for parts of the viral genetic material (RNA in the case of COVID-19) in our bodies and amplify it so that we can detect it are extremely sensitive and even detect certain viral fragments. Attendance can also be raised. This is because fragments of viral RNA can remain in our bodies even after the infection is over and the virus has been cleared from our system.

If you have the virus and want to avoid spreading it, the best thing to do is to isolate for at least a full five days. You can then leave isolation after you test negative for two consecutive days — if you have tests available — or after 10 days if you don’t test negative. At this point you should no longer be contagious to others.

What should you do if you have symptoms?

If you have symptoms of COVID-19 you do not need to be tested or self-isolate if you are in England.

However, the NHS advises anyone with symptoms to stay home and avoid contact with others.

If you test positive or experience symptoms, the NHS recommends taking the following steps:

  • try to work from home if you can – if you are unable to work from home, ask your employer about the options available to you;
  • Stay home if possible – this helps reduce the number of people you come in contact with;
  • Avoid contact with people at high risk of COVID-19, especially if their immune system means they are at higher risk of serious illness from COVID-19, even if they have had the vaccine;
  • Follow advice on how to avoid spreading the virus to people you live with;
  • Let people who need to come into your home know you’ve tested positive or have symptoms – then they can take steps to protect themselves, such as wearing a well-fitting face wash, as much as you can staying away as much as possible, and washing hands regularly;
  • Contact your healthcare provider and tell them about your positive test result or symptoms if you are asked to attend a medical or dental appointment in person;
  • Ask friends, family or neighbors to bring you food or other essentials.

If you live in Scotland, Wales or Northern Ireland, the advice is as follows:

If you test positive for COVID-19, you must self-isolate for the full five days. The first day is the day after your symptoms started or the day after your test if you do not have symptoms (whichever is earlier).

Then you should do a lateral flow test on the fifth day. If it’s negative and you don’t have a high temperature, you can self-isolate on the sixth day.

However, if you still have a temperature and feel unwell, you should continue to self-isolate until your temperature returns to normal or you feel better.

If on the fifth day or the sixth day the test is positive, you should continue with the daily lateral flow test until you get two consecutive negative tests, spaced a day apart or on day 10 – whichever is earlier.
