How Long After Having Covid Will You Test Negative

Continue To Wear A Mask

VERIFY: Can you test positive for COVID-19 long after you’re contagious?

Even if you have recovered from COVID-19 or are fully vaccinated, it’s still important to wear a mask indoors in a public setting and in close contact areas.

According to the CDC guidelines, in people who have recovered from COVID-19, testing is not recommended as part of a contact tracing program or new exposures within three months of a positive COVID-19 test. During these three months, a positive test result could be associated with the previous infection rather than a new infection.

However, this recommendation differs if a person experiences symptoms consistent with COVID-19 within the three months. In that case, repeat testing is recommended. If the test is positive, patients should undergo a repeat five-day isolation period, according to recommended guidelines.

Less Sensitive Lateral Flow Or Rapid

The precise timing of these events is influenced by the rate at which the virus replicates once it has infected cells, and whether these cells are implicated in transmitting the virus to other people – as well as how much virus the person was initially exposed to, how they were exposed, their biological susceptibility to that type of virus and their immune response.

Similar factors may also influence when individuals start to test positive for the virus, using diagnostic tests such as PCR or lateral flow tests.

How Long Do You Test Positive For Covid After Having It

Covid-19 has been a substantial part of our lives since the start of the pandemic in early 2020.

As the scientific community and governments across the globe continue their race against time to understand the virus and decide on best practices, we are learning more and more about the implications of the virus.

One recent learning has been that some patients continue to test positive for Covid weeks and sometimes months after their first positive test.

But, how long can you test positive for Covid after catching it and when will you stop being contagious with the virus?

Who Should Get Tested

If you have symptoms of COVID-19, you may need to be tested. Contact your own primary care provider for advice on what to do next.

If you are coming to campus regularly, the Covid Pass app will notify you when you need to be tested. But, remember, if you have symptoms or have been exposed to someone who has tested positive for COVID-19, do not come to be tested at the Covid Pass testing site.

You Do Not Have To Isolate / Quarantine While Your Are Waiting For Your Test Result If:

  • you have not travelled outside of Canada within the last 14 days and:
  • You have not tested positive on another test in the last 10 days such as a rapid test
  • you are waiting for results and you did not have symptoms when you were tested and do not have any now
  • you have symptoms of illness that are related to a pre-existing illness or health condition, and are not new.
  • you have tested negative for COVID-19 and have no symptoms of illness
  • you have tested negative for COVID-19 and have a cough, fever, shortness of breath, runny nose, or sore throat that is related to a pre-existing illness or health condition. We do always suggest you stay home when sick with any illness, until symptoms resolve however, if your COVID-19 test is negative, this is not legally required.

How Does An Antibody Test Work

An antibody test is a blood test that looks for immune molecules, or antibodies, specifically targeted to fighting SARS-CoV-2, the virus that causes the COVID-19 illness. An antibody test for COVID-19, if accurate, could indicate if you had previously been infected with the virus, even if you never had any symptoms.

If You Live In The Same Household As Someone With Covid

Follow separate guidance if you have had contact with someone who has tested positive for COVID-19 but do not currently live in the same household as them.

Anyone who has symptoms of COVID-19 should stay at home, self-isolate immediately and order a PCR test.

If you do not have symptoms of COVID-19 and live in the same household as someone with COVID-19, you are legally required to self-isolate unless you meet any of the following conditions:

  • you are fully vaccinated. Fully vaccinated means you have had 2 doses of an approved vaccine such as Pfizer BioNTech, AstraZeneca or Spikevax . You are also fully vaccinated if you have had one dose of the single-dose Janssen vaccine
  • you are below 18 years 6 months
  • you have taken part in or are currently part of an approved COVID-19 vaccine trial
  • you are not able to get vaccinated for medical reasons

If you meet any of these four conditions , follow the guidance further down for contacts who are not legally required to self-isolate.

When Is The Best Time To Get Tested After Exposure

The CDC states that anyone who may have been exposed to someone with COVID should test five days after their exposure, or as soon as symptoms occur.

“If symptoms occur, individuals should immediately quarantine until a negative test confirms symptoms are not attributable to COVID-19,” the guidance states.

Medical experts say that even though incubation times are changing, those who test early should continue testing even if they get negative results.

Caring For Yourself After Covid

How long after I get COVID-19 will I test negative?

You can only leave isolation after 7 days , and if your symptoms have cleared up.

Make time to follow-up with your doctor after you leave isolation.

Most people who test positive for COVID-19 recover completely, but some people may develop long COVID.

Talk to your GP if you are experiencing ongoing mental health issues such as:

  • trouble thinking clearly, focusing, or remembering
  • depression, anxiety or other mental health problems.

How Long Does It Take To Get The Results

You should get your test results within 2 days of being tested. Sometimes there are delays and it can take longer. Therefore, we ask that you only contact your testing provider after 72 hours if you have not received your test results.

Victorian and interstate labs are working around the clock to process all the tests, but with so many coming in every day, sometimes it takes a little longer to confirm the results.

You will receive a text or phone call about your results.

You And Your Household Contacts Must Isolate At Home

You must self-isolate at home for 7 days from the date you got tested, even if you are fully vaccinated. Self-isolation means staying in your home or accommodation and remaining separated from others. Please see the Self-Isolation Guideline for further information on how to self-isolate and what supports are available to you should you need them.

You must tell people you live with that you have COVID-19. Your household contacts must also self-isolate for 7 days, and have a rapid antigen test as soon as possible and again on Day 6 .

The NSW Health Isolation Support Line, is available for practical assistance during self-isolation on 1800 943 553.

Requirements To Leave Isolation

You can leave isolation 7 days after the date your positive test was taken if you are no longer experiencing symptoms such as temperature, fever, headaches and body aches. If you are still experiencing any of these symptoms, you should isolate for an extra 3 days, for a total of 10 days in isolation.

Some symptoms, such as a cough and tiredness, can last for some time after you have left isolation. These symptoms do not mean you are infectious. You should see your GP if these symptoms continue.

Public Health will send you an email on day 7 of your isolation. This email will contain an official letter of release from isolation and can be used as proof of release or as a medical certificate.

Positive Dont Test Again


If you have gotten a positive result on a test, there is no point in testing any further.

Health departments say if you test positive, dont keep testing repeatedly in search of a negative test, Amler said. Any positive test is a positive result, so you will just be wasting scarce test kits.

The only time to retest is if you test negative after you have been exposed to someone with the virus or if you have symptoms. It can take time for the virus to build up to levels that are detectable.

You want to test on day three and five or day four and day six after exposure, just to make sure you are negative, Wells said.

What Should I Do If Multiple People I Live With Test Positive For Covid

Recommendations for this situation depend on vaccination status:

  • When multiple members of the household become infected at different times and the people with COVID-19 cant isolate from other members of the household, close contacts who are unvaccinated or not fully vaccinated should
  • Quarantine throughout the isolation period of any infected person in the household.
  • Continue to quarantine until 14 days after the end of isolation date for the most recently infected member of the household. For example, if the last day of isolation of the person most recently infected with COVID-19 was June 30, the new 14-day quarantine period starts on July 1.
  • Get tested 5-7 days after the end of isolation for the most recently infected member of the household.
  • Wear a mask when in contact with any person with COVID-19 while that person is in isolation.
  • Wear a mask when in contact with other people in the home until quarantine ends.
  • Isolate immediately if they develop symptoms of COVID-19 or test positive.
  • When multiple members of the household become infected at different times and the people with COVID-19 cant isolate from other members of the household, close contacts who are fully vaccinated in this situation should
  • Get tested 5-7 days after their first exposure. A person with COVID-19 is considered infectious starting 2 days before they developed symptoms, or 2 days before the date of their positive test if they do not have symptoms.
  • How Do I Manage A Baby Or Child With Covid

    Most children who test positive for COVID-19 can be safely cared for at home by their usual household carers, even if they are not vaccinated. When caring for your child with COVID-19 at home:

    • Dress your child in appropriate clothing, so that they are comfortable not sweating or shivering
    • Give your child plenty of fluids to drink. They may not feel like drinking much so will need your help and encouragement.
    • If you are breastfeeding or formula feeding your baby may want more frequent feeds. Breastfeeding is safe to continue if you and/or your baby has COVID-19.
    • Encourage them to rest and not overdo it
    • Use paracetamol or ibuprofen, only if you think your child is in pain or appears uncomfortable with a fever. Follow the instructions on the label, and do not give more of these medicines than is recommended in a 24-hour period, as this may be harmful for children.
    • Watch your child for signs that their illness is getting worse.

    Monitor your child’s condition and if you notice:

    • persistent fever which is not responding to treatment
    • mild breathlessness
    • drinking less than half of what they would normally drink
    • urine output less than half of usual volume, and urine dark in colour
    • moderate vomiting or diarrhoea
    • unable to stand or walk.

    If you are concerned that your child is seriously unwell, has difficulty breathing, is severely dehydrated or fainting, please

    I Tested Positive For Covid

    If you continue to have no symptoms, you can be with others after 10 days have passed since you had a positive viral test for COVID-19 .

    If you develop symptoms after testing positive, your 10-day isolation period must start over. Day 1 is your first day of symptoms. Follow the guidance above for I think or know I had COVID-19, and I had symptoms.

    People Who Are Contacts Of Someone Who Tests Positive For Covid

    How long can you test positive after a COVID-19 test?

    Please share thishigh-risk contact letterto anyone you were in close contact with, beginning 48 hours before your symptoms started , up until you started self-isolating.

    If you are a contact of someone who tests positive for COVID-19, you may need to self-isolate.

    If you are a contact, you may be notified of your exposure in different ways depending on the situation. You may be reached:

    If you receive a phone call, you will be told:

    • The date you were exposed to the person who tested positive for COVID-19
    • How long you need to isolate for
    • When you should go for testing
    • What to tell your household members

    You will not be told:

    • Who exposed you
    • Where you were exposed

    You would be considered a high-risk contact and must self-isolate “Self-isolation period for people who have symptoms of COVID-19 but cant get tested” as mentioned above.

    Only go for testing if you are eligible. See our testing webpage for testing criteria.
    If you live in the same household as someone who is a high-risk contact who does not have symptoms.

    You are not required to self-isolate.

    Only go for testing if you are eligible. See our testing webpage for testing criteria.

    In all circumstances we advise avoiding vulnerable persons such as residents of long-term care homes, hospital patients or people with chronic illnesses that may compromise their immune system.

    You May Be Able To Shorten Your Quarantine

    Your local public health authorities make the final decisions about how long quarantine should last, based on local conditions and needs. Follow the recommendations of your local public health department if you need to quarantine. Options they will consider include stopping quarantine

    • After day 10 without testing
    • After day 7 after receiving a negative test result


    In areas using options to reduce quarantine times, people who are asymptomatic can use a negative test result collected on day five after exposure to exit quarantine on day seven , with additional self-monitoring. The day of exposure is considered day zero .

    If Someone Continues To Test Positive For Covid

    The question to retest becomes more confusing when we add the element of repeat infection.

    People who have recovered from COVID-19 develop protective antibodies that help prevent the virus from replicating and infecting new cells. However, scientists do not fully understand the effectiveness of this antibody protection or how long it lasts.

    Some research has suggested that neutralizing antibodies are present for at least six months. Therefore, the risk of reinfection is low but not impossible, and reinfection is more likely in unvaccinated people.

    This concept also applies to people who are fully vaccinated, as breakthrough infections can occur in fully vaccinated people.

    Who This Guidance Is For

    This guidance is for:

    • people with symptoms that may be caused by COVID-19, including those who are waiting for a test
    • people who have received a positive COVID-19 test result
    • people who currently live in the same household as someone with COVID-19 symptoms, or with someone who has tested positive for COVID-19

    In this guidance a household means:

    • one person living alone
    • a group of people living at the same address and who share cooking facilities, bathrooms or toilets, or living areas. This may include students in boarding schools or halls of residence who share such facilities
    • a group of people who share a nomadic way of life for example those who live on Traveller sites, in vehicles or on canal boats

    This guidance applies in England.

    When Are People With Covid Most Contagious

    Tested positive for Covid

    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.

    If You Develop Symptoms While You Are Self

    If you develop symptoms while you are isolating, you should arrange to have a COVID-19 PCR test. If your test result is positive, follow the advice for people with COVID-19 to stay at home and start a further full 10 day isolation period. This begins when your symptoms started, regardless of where you are in your original 10 day isolation period. This means that your total isolation period will be longer than 10 days.

    If this PCR test result is negative, you must continue to self-isolate as you could still become infectious and pass the infection on to others. Stay at home for the full 10 days to avoid putting others at risk.

    If other household members develop symptoms during this period, you do not need to isolate for longer than 10 days.

    What The Cdc Says About Retesting After A Positive Covid Test

    The CDC recommends staying home or away from others for five full days if you test positive for COVID , or if you have symptoms, regardless of vaccination status. If you absolutely have to be around other people , you should wear a well-fitted mask.

    After those five days, the CDC says you can end isolation if you didn’t develop symptoms, or if you developed symptoms but have been fever-free for 24 hours and your symptoms are improving. However, you still have to wear a mask for five more days, the CDC says.

    For both of these scenarios, the CDC says retesting yourself is an option, not a requirement: “If an individual has access to a test and wants to test, the best approach is to use an antigen test towards the end of the five-day isolation period,” the CDC guidelines read. “Collect the test sample only if you are fever-free for 24 hours without the use of fever-reducing medication and your other symptoms have improved.” If you end up testing positive again, the CDC recommends you continue isolating until day 10.

    This guidance differs a bit if you had severe illness from COVID-19, or if you have a weakened immune system: In that case, the CDC says you may require additional viral testingmolecular or antigen teststo determine if and when it’s safe to be around others. In that case, the best course of action is to talk with your doctor to determine a testing plan.
