Exactly How Long Covid
DiGiallorenzo is right to say its somewhat of a guessing game. Researchers dont know why some people are testing positive for longer than others and theyre scrambling to figure out if those prolonged positive test results mean people are still contagious.
A recent study out of Beijing examined 16 patients with COVID-19 and found that half continued to test positive even after their symptoms, such as cough and fever, ended. Those patients had markers of shedding, indicating they could still spread the disease for up to eight days after they recovered.
Two other studies from Wuhan, China, found similar evidence, suggesting that people are still contagious after theyve clinically recovered. On average, people with COVID-19 shed or emit the virus for 20 days, with some shedding it for up to 37 days.
One of the major obstacles thats prevented us from gathering more evidence on how long the virus sheds is the ongoing lack of widespread testing. In the United States, we barely have enough tests to evaluate those who are presenting symptoms for the first time, let alone people who are coming back for a second test. DiGiallorenzos experience is rare.
Because there is currently a shortage of tests, testing post-symptomatic people may not be a priority for their use, said Ben Singer, a pulmonologist and assistant professor of pulmonary and critical care medicine at Northwestern University Feinberg School of Medicine.
Wear A Mask To Protect From Contagion
Mask mandates are being lifted, but wearing a mask in crowded indoor areas is still a highly effective way to protect yourself and other people from COVID-19especially as you have no idea who is or isn’t vaccinated, or might be contagious. “There’s just been a lot of whiplash in terms of what people have been saying, because at the beginning of the pandemic, people were saying not to wear masks, and now all the health experts are saying that you should wear masks,” says ob-gyn resident Pratistha Koirala, MD, Ph.D. “Medicine changes and it evolves. The more we learn about something, the better we’re able to treat it.”
False Negative: How Long Does It Take For Coronavirus To Become Detectable By Pcr
It takes time for coronavirus to become established in the body, so a negative test doesnt necessarily mean you wont test positive later on.
You sit next to someone who is infected with coronavirus. As they breathe out and you breathe in, some of their viral particles become attached to cells lining your nose and upper airways, and begin to gain entry. Yet, if you were to do a PCR test at this stage, you would most likely test negative. Why?
At the beginning of any viral infection, including COVID-19, there is a period of time called the latent period when a person is infected, but is unable to transmit the virus to anyone else. There is also a period known as the incubation period before they develop symptoms. The degree to which they overlap depends on the virus. For instance, people infected with Ebola develop symptoms before they become infectious, whereas with COVID-19, they usually become infectious before they develop symptoms and many people never develop symptoms at all. This is what makes COVID-19 so difficult to contain the most successful intervention is often implemented too late, as people are unaware that they are infectious due to a delay in symptom onset. The average incubation period for COVID-19 is 5-6 days , and researchers estimate that people become infectious 2-3 days before they develop symptoms.

What If I Am Pregnant And Have Covid
Pregnant women, who are 14 weeks or more, have a higher risk of complications from COVID-19.
If you test positive to COVID-19 and you are more than 14 weeks pregnant, it is important that you tell your maternity care provider. This may be your GP, midwife, obstetrician or local maternity service.
Most pregnant women will be able to safely stay at home while they have COVID-19. During this time, it is important to:
- Have plenty of fluids, like you would with a regular cold or flu. If you feel unwell, paracetamol can also be taken to help with symptoms. Ibuprofen is not recommended to take while you are pregnant. It is important to mobilise regularly to reduce your risk of developing blood clots.
- It is important to keep a close eye on your babys movements. Call your maternity care provider immediately if your babys movements change or if you experience:
- vaginal bleeding
- sudden swelling of your face and hands
- you are in labour
- have any serious concerns about your pregnancy.
When Are People With Covid Most Contagious
The CDC says that its guidelines were updated to reflect growing evidence that suggests transmission of COVID-19 often occurs one to two days before the onset of symptoms and during the two to three days afterward.
For those without symptoms, CDC guidance states they are considered contagious at least two days before their positive test.

Why You Should Quarantine After Exposure To Covid
If you’ve been exposed to the novel coronavirus, your first instinct might be to run out for a test, but being tested for COVID-19 too early in the incubation period could deliver a false sense of security and lead you to engage in risky behaviors that could cause others to become infected.
“Someone can get a positive test result as soon as two days after exposure, but we typically ask our patients to wait at least five days for most accurate test results,” Nailah Abdulbaaqee, MD, a primary-care provider at One Medical in Atlanta, told POPSUGAR.
However, there are no set guidelines for when a person with a known exposure should be tested for COVID-19, and a negative result early on in the two weeks after exposure is no excuse to skip the recommended quarantine. “Testing too early may show you are negative for COVID-19, but this does not mean that you cannot test positive later in the 14-day window,” said Kristin Dean, MD, a family medicine physician and medical director at Doctor On Demand. “COVID-19 symptoms may develop up to 14 days after the day of the last exposure to COVID-19.”
It’s difficult to nail down a timeline for testing because people can respond differently to the virus based on their individual immune system and the type of exposure that occurred, Dr. Dean explained. Additionally, “the virus takes time to replicate after exposure. Sometimes the virus circulating in your body is not sufficient to show up as positive on a COVID-19 test.”
How Will My Covid
When you register your positive RAT result, you will be asked to answer questions that help us determine whether you are at risk of getting severe disease. If you had a positive PCR result, you will be sent the survey by text message. Please reply to the survey as soon as you can.
You will also be sent advice on self-isolation and how to look after your illness at home. If you are at risk of severe disease you will be linked to NSW Health clinical services.
If you are under 65 years of age, have had two doses of COVID-19 vaccine, do not suffer from any chronic health conditions and are not pregnant, you can safely look after yourself at home. Most people with COVID-19 will have a mild illness and will recover in a few days or so, with some people having no symptoms at all.
Most symptoms can be managed with:
- Bed rest
- Regular paracetamol and ibuprofen to relieve pain and fevers
- Throat lozenges for a sore throat
- Keeping hydrated with regular sips of water.
Continue to take any medications you have been prescribed as usual. If you are unsure about continuing to take your current medication or treatment, or have any concerns about your health, call your doctor.
Please contact your GP or call the NSW Health COVID-19 Care at Home Support Line on 1800 960 933 if you are considered to be at high risk of severe disease. People considered at high risk of severe disease include:

So What Does This Mean For Travel
Laura Jackson from ABTA says the first thing we should do before travelling is check the entry requirements on the UK government website.
Some countries will say, regardless of your vaccination status, that you need to show proof of a PCR test whereas others could ask for lateral flow, she says.
For fully vaccinated travellers, generally theres more likelihood that you wont need to take test or that the testing requirements will be reduced in some way.
Jackson continues: Some destinations will accept proof of recovery for entry and thats probably a better option for someone who is unvaccinated than fully vaccinated, because if youre fully vaccinated, people most likely be able to use your proof of vaccination rather than proof of recovery.
If You Have Symptoms At Day 7
If you have a sore throat, runny nose, cough or shortness of breath in the last 24 hours of your isolation, please remain in isolation until 24 hours after your symptoms have resolved. If you are concerned, call your GP.
Wear a mask when near to or talking to other people and avoid visiting high risk settings for a further 3 days after you leave isolation. If you work in one of these settings speak to your employer before returning. If you have a severely weakened immune system you should take these additional precautions for a further 4 days .
If you have other symptoms after 7 days which are not getting better you can leave isolation but you should contact your GP.
If you are under the care of a clinical team, your team will tell you when you will be released from isolation.

How Long Do I Need To Isolate After A Positive Test
The Covid-19 self isolation period starts immediately from when your symptoms started, or from when a positive lateral flow or PCR test was taken if you do not have any symptoms – whichever test was taken first.
From this point, your isolation then includes the next 10 full days.
However, new rules in England mean that people who test positive only have to self isolate for seven days.
From Wednesday , those in England who receive a negative lateral flow test result on day six and day seven of their self-isolation period no longer have to quarantine for the full 10 days.
The isolation period is 10 days for those who do not live in England.
There is no change to the guidance for unvaccinated contacts of positive Covid-19 cases, who are still required to self-isolate for 10 full days after their date of exposure to the virus.

What About Long Covid
Long Covid is the term commonly used when symptoms related to COVID-19 continue for monthsbut there’s also a chance someone might be infected with a new variant such as Omicron. If you don’t feel well and aren’t sure if what you’re experiencing is Long Covid or a new infection, get tested and use precautions such as social distancing and mask-wearing to protect the people around you. “If you have long COVID symptoms, you should seek care,”says AMA member Devang Sanghavi, MD. “As we have seen in a lot of these surveys and studies about post-COVID syndrome is that usually this condition doesn’t come with just one symptomthere’s a cluster of symptoms. Don’t label it as post-COVID right away. You want to make sure that it’s not something new, and then you obviously want to make sure that your symptoms are addressed, based on the severity.”

How Long After Covid Exposure Could You Test Positive
According to the CDC, the incubation period for COVID is between two and 14 days, though the newest guidance from the agency suggests a quarantine of five days for those who are not boosted, but eligible or unvaccinated. Those looking to get tested after exposure should do so five days after the exposure or if they begin experiencing, the CDC recommends.
Those who are boosted and vaccinated, or those who are fully vaccinated and not yet eligible for a booster shot, do not need to quarantine, but should wear masks for 10 days and also get tested five days after the exposure, unless they are experiencing symptoms.
Still, for those who are vaccinated and boosted but are still looking to be cautious, medical experts say an additional test at seven days could help. But testing is likely not necessary after seven days following exposure for those who are vaccinated and boosted.
How Long Can You Test Positive For Covid
The Omicron Covid-19 variant outbreak has seen UK cases skyrocket, with more than one million people are currently self-isolating.
There have been many reports of people testing positive after their 10-day isolation.
This has caused confusion and anxiety for those at the end of their isolation period for fears that they might still be infectious and will have to remain inside for longer, even if they dont have symptoms.
Here, Metro.co.uk explains how long you could test positive for Covid-19, and whether you are still allowed to leave isolation once your 10 days are up.

Still Testing Positive For Covid
We may be entering our third year of the COVID-19 pandemic, but we’re still getting the hang of testing. And, for people who continue to test positive for coronavirus late into their infection, it may be particularly difficult to know what to do with those results.
If you test positive for COVID-19, you can end your isolation after just five days if you never developed symptoms, according to the latest guidelines from the Centers for Disease Control and Prevention.
Or, if you did develop symptoms, you can leave isolation after you’ve been without a fever for 24 hours , provided your other symptoms are resolving as well. That can be as early as after five full days of isolation, the CDC says.
The CDC also amended its guidelines to add that, if you have access to a rapid antigen test, you can take the test at the end of day five of your isolation . If it’s negative, you can use that result to feel more confident about leaving isolation at that time. But if it’s positive, the CDC says you should continue isolating through day 10.
The government is providing at-home COVID-19 tests to Americans for free. Every household in the U.S. can order up to four tests. Administration officials have predicted it will take seven to 12 days for the tests to ship, but some Americans have already received their tests.
How Long Do I Need To Self
Self-isolation requirements are now determined by a persons age, household situation and vaccination status.
A fully vaccinated person or a child 11 years old or younger:
- Must isolate for a minimum of seven days following the onset of symptoms or a positive test .
- Can leave isolation the morning of the 8th day if they no longer have symptoms, or symptoms are improving and there has been no fever for at least 24 hours.
A person who is not fully vaccinated, or a person who is immunocompromised and has not received a third vaccine dose:
- Must isolate for at least 10 days following the onset of symptoms or a positive test .
- Can leave isolation the morning of the 11th day if they no longer have symptoms, or symptoms are improving and there has been no fever for at least 24 hours.

How Do Saliva Tests Compare To Nasal Swab Tests For Diagnosing Covid
Samples for COVID-19 tests may be collected through a long swab that is inserted into the nose and sometimes down to the throat, or from a saliva sample.
The saliva test is easier to perform spitting into a cup versus submitting to a swab and more comfortable. Because a person can independently spit into a cup, the saliva test does not require interaction with a healthcare worker. This cuts down on the need for masks, gowns, gloves, and other protective equipment.
Either saliva or swab samples may be used for PCR tests, which detect genetic material from the coronavirus. Swab or saliva samples can also be used for antigen tests, which detect specific proteins on the surface of the coronavirus.
A systematic review and meta-analysis published in JAMA Internal Medicine found that saliva- and nasal swab-based tests that used a technique similar to PCR were similarly accurate. A positive result on either test meant that it was accurate at diagnosing the infection 99% of the time. However, approximately 16 out of 100 people who are infected will be missed.
These results are very similar to prior studies, reinforcing that a single negative swab or saliva test does not mean you dont have COVID. If you have symptoms suggestive of COVID, presume you may still be infected to avoid transmitting the virus to others.
