How Long Does It Take To Show Symptoms Of Covid

If You’ve Been Exposed Are Sick Or Are Caring For Someone With Covid

Researchers learn more about length of COVID-19 symptoms, treatments

If you’ve been exposed to someone with COVID-19 or begin to experience symptoms of the disease, you may be asked to self-quarantine or self-isolate. What does that entail, and what can you do to prepare yourself for an extended stay at home? How soon after you’re infected will you start to be contagious? And what can you do to prevent others in your household from getting sick?

Visit our Coronavirus Resource Center for more information on coronavirus and COVID-19.

What If You Have Covid

If you have COVID-19, do the following:

  • Stay home and only leave to receive medical care.
  • Try to separate yourself as much as possible from others in your household.
  • Wear a mask when you need to be around other people.
  • Take care of yourself by staying hydrated or taking over-the-counter medications to alleviate symptoms.
  • Monitor your symptoms and seek medical attention if they begin to get worse.

According to the , you can be around others again if all of the following are true:

  • Its been at least 10 days since your symptoms started.
  • Youve gone 24 hours with no fever .
  • Your other symptoms have started to improve.

When To Seek Emergency Medical Attention

Look for emergency warning signs* for COVID-19. If someone is showing any of these signs, seek emergency medical care immediately:

  • Trouble breathing
  • Persistent pain or pressure in the chest
  • New confusion
  • Inability to wake or stay awake
  • Pale, gray, or blue-colored skin, lips, or nail beds, depending on skin tone

*This list is not all possible symptoms. Please call your medical provider for any other symptoms that are severe or concerning to you.

What If I Develop Symptoms That Could Be Covid

  • Schedule a test via myD-H or learn more on our COVID-19 Testing FAQ page
  • Tell close contacts to quarantine. Tell anyone you have been in close contact with since 72 hours before your first symptom began that you feel unwell and they should quarantine for 10 days. Follow up with them when you receive your test results if you receive a negative test, then they no longer need to quarantine.
  • Do not delay any medical care you need. Call your primary care provider to schedule a telemedicine Virtual Visit at 603-354-5400.
  • For urgent virtual or in-person primary care, call our Urgent Visits team at . They may care for you via phone, virtual visit, or at our KARES unit.
  • Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.

    If you develop emergency warning signs for COVID-19, get medical attention immediately by calling 911. Emergency warning signs include*:

    • Difficulty breathing or gasping for breath
    • Persistent pain or pressure in the chest
    • New confusion or inability to arouse
    • Bluish lips or face
    • *This list is not all-inclusive. Please consult your primary care team or our urgent primary care visit team for any other symptoms that are severe or concerning.

    How Are Coronavirus Symptoms Different From Allergy Symptoms What About Flu Colds And Strep Throat

    How Long Does It Take for COVID Symptoms to Appear?

    COVID-19 shares symptoms with other conditions such as allergies, the flu or strep throat. It may be very hard to tell the difference between COVID-19 and flu without a test.

    If you have symptoms that might be due to the coronavirus, contact a health care provider, describe your symptoms and follow their recommendations.

    How Reliable Are The Tests For Covid

    Two types of diagnostic tests are currently available in the US. PCR tests detect viral RNA. Antigen tests, also called rapid diagnostic tests, detect specific proteins on the surface of the coronavirus. Antigen test results may come back in as little as 15 to 45 minutes you may wait several days or longer for PCR test results.

    The accuracy of any diagnostic test depends on many factors, including whether the sample was collected properly. For PCR tests, which are typically analyzed in a laboratory, test results may be affected by the conditions in which the test was shipped to the laboratory.

    Results may also be affected by the timing of the test. For example, if you are tested on the day you were infected, your test result is almost guaranteed to come back negative, because there are not yet enough viral particles in your nose or saliva to detect. The chance of getting a false negative test result decreases if you are tested a few days after you were infected, or a few days after you develop symptoms.

    Generally speaking, if a test result comes back positive, it is almost certain that the person is infected.

    A negative test result is less definite. There is a higher chance of false negatives with antigen tests. If you have a negative result on an antigen test, your doctor may order a PCR test to confirm the result.

    What This Means For You

    If you get COVID-19, you may test positive on a PCR test for several weeks after you have ceased to be infectious. With a rapid test, you may test positive for six or seven days after your symptoms have cleared.

    What Should You Do If Youre Fully Vaccinated And Have Been Exposed To The Coronavirus

    If youre fully vaccinated, you dont have to quarantine after being in close contact with someone with COVID-19 unless you develop symptoms. However, you should still:

    • Monitor yourself for symptoms of COVID-19.
    • Get tested 5 to 7 days after exposure.
    • Wear a mask while in indoor public spaces for 14 days or until your COVID-19 test comes back negative.

    Its important that some people contact their doctor promptly if they believe that theyve been exposed to COVID-19, even if theyre fully vaccinated. These individuals include:

    • older adults
    • people with underlying health conditions that increase their risk of serious illness
    • those with a weakened immune system
    • pregnant people

    There are treatments available, such as monoclonal antibodies, that can help prevent serious illness in higher risk individuals.

    If I’m Exposed To The Coronavirus How Long Before I Develop Symptoms

    How long it can take for COVID-19 symptoms to develop

    Symptoms can begin between two and 14 days after you have been infected with the SARS-CoV-2 coronavirus. A study led by researchers at the Johns Hopkins Bloomberg School of Public Health shows that the median time for symptoms to show up is about five days. That is why the CDC uses the 14-day quarantine period for people following exposure to the coronavirus.

    Latest Coronavirus News As Of 12pm 10 March

    The monoclonal antibody sotrovimab has been linked to a drug-resistant mutation in SARS-CoV-2.

    A study in Australia suggests that sotrovimab, a treatment for covid, may cause the coronavirus to acquire mutations that enable it to resist the drug.

    Sotrovimab neutralises SARS-CoV-2s spike protein, which the virus uses to enter cells. Given through a drip, sotrovimab can be administered to people within five days of their infection to prevent symptoms from becoming severe.

    Rebecca Rockett from the University of Sydney and her colleagues reviewed the first 100 people who received sotrovimab at a healthcare facility in New South Wales between August and November 2021, when the delta variant of the virus was dominant. Eight of the people who were treated persistently tested positive for SARS-CoV-2, and had airway samples collected before and after they received sotrovimab.

    In four of these patients, SARS-CoV-2 developed spike mutations between six and 13 days after sotrovimab was administered, with these genetic changes making the drug effectively inactive, said Rockett, as reported in The Guardian.

    The researchers are calling for increased genomic surveillance around sotrovimabs use. What we dont want to see is resistant virus disseminating in the community, because that will mean that a lot of other people cant use this drug as well, said Rockett.

    What If You Test Positive Using An At

    Those who test positive using an at-home test are asked to follow the latest CDC guidelines and communicate the results to their healthcare provider, who is responsible for reporting test results to the state health department.

    According to Chicago-area health departments, people should assume the test results are accurate and should isolate from others to reduce the risk of spreading the virus.

    “If you test positive for COVID-19, you must isolate,” Arwady said. “There is no need to repeat a positive at-home test in a medical setting. We don’t want people going into the emergency department just to get a tested. Treat a positive as a positive, stay home and isolate for five days.”

    What Are The Possible Symptoms Of Covid

    Please see the CDC’s Symptoms of Coronavirus page for the most up-to-date information.

    Any one of the following symptoms may indicate COVID-19, if new and not explained by another health condition:

    • Fever or chills
    • Cough
    • Shortness of breath or difficulty breathing
    • Fatigue
    • New loss of taste or smell
    • Sore throat
    • Nausea or vomiting
    • Diarrhea

    Recently, patients testing positive with the Delta variant of COVID reported experiencing symptoms often mistaken for allergies: sore throat, cough, headache, congestion. Lately, fewer patients are reporting loss of taste and smell than those infected with the virus variants circulating in our community last year. Please get tested for COVID-19 if you experience allergy-like symptoms.

    Some people with COVID-19 also experience neurological symptoms, gastrointestinal symptoms. These may occur with or without respiratory symptoms. See Harvard Health’s If you’ve been exposed to the coronavirus.

    Many of these symptoms are also symptoms of other viruses and medical conditions, so it is important to protect those around you until you receive test results that indicate if you have COVID-19.

    Millions of people continue to suffer from exhaustion, cognitive problems and other long-lasting symptoms after a coronavirus infection. The exact causes of the illness, known as long Covid, are not known. But new research offers clues, describing the toll the illness takes on the body and why it can be so debilitating.

    Researchers also determined that infected individuals were more likely to be asymptomatic if they contracted the virus from a primary case.

    While household members of primary cases had higher infection rates than other close contacts, close contacts were more likely to contract COVID-19 if they were exposed shortly before or after the individual developed noticeable symptoms.

    According to the Massachusetts Institute of Technology, another study found that contagiousness both began and peaked before the first symptoms of illness 2.3 days and 0.7 days respectively. Researchers concluded that about 44 percent of COVID-19 infections spread from person to person before symptom onset.

    As a result, according to MIT’s website, the CDC considers contract tracing, identifying close contacts, vital in protecting communities from further spread. A close contact is defined as someone who has been within 6 feet of a COVID-positive individual for a cumulative total of 15 minutes or more over a 24-hour period.

    “Time is of the essence,” the CDC’s website stated. “If communities are unable to effectively isolate patients and ensure contacts can separate themselves from others, rapid community spread of COVID-19 is likely to increase to the point that strict mitigation strategies will again be needed to contain the virus.”

    What Counts As Close Contact And Exposure To Covid

    Close contact:

    • Being within 6 feet of someone for a cumulative total of 10 minutes or longer during the persons infectious period. This exposure can occur over multiple separate contacts or even days.
    • Providing care at home to someone who is sick with COVID-19.
    • Having direct physical contact with the person
    • Sharing eating or drinking utensils.
    • Being sneezed on or coughed on.

    While wearing masks, being outdoors, and being fully vaccinated significantly reduce virus transmission, these do not eliminate the risk of infection altogether. These circumstances are still considered close contact to an infectious person, especially for prolonged periods of time.

    Infectious period: A person is generally infectious 48 to 72 hours before they develop COVID-19 symptoms and for 10 days after their first symptoms appear. Some people who develop more serious or severe symptoms may be infectious for a longer period please contact your primary care provider for recommendations.

    Exposure can mean being in close contact with:

    • Someone who has possible symptoms of COVID-19, unless they test negative while they are sick.
    • Someone who developed symptoms one to two days after you were in close contact. People with COVID-19 may be contagious 48 to 72 hours before they develop symptoms.
    • Someone who has not become ill with symptoms but tested positive for COVID-19 within 7 days of your close contact.

    The Fda Has Granted Emergency Use Authorization To A Rapid Antigen Test For Covid

    The BinaxNOW COVID-19 Ag Card, as the test is known, detects antigen proteins on the surface of SARS-CoV-2, the virus that causes COVID-19. Unlike other diagnostic tests for COVID-19, BinaxNOW does not require a laboratory or other equipment to process or analyze the test results. This makes it portable and fast results are available within 15 minutes.

    This test is approved for use in people who are suspected of having COVID-19, and must be done within seven days of when their symptoms began. A prescription is needed to get this test, which can be performed in authorized locations including doctor’s offices and emergency rooms.

    To perform the test, a sample obtained using a nasal swab is inserted into the BinaxNOW test card. The test is a lateral flow immunoassay, which works like a pregnancy test. The appearance of colored lines on the test strip indicates whether or not you have tested positive for COVID-19. The test comes with a smartphone app that can be used to share test results.

    Positive test results are highly specific, meaning that if you test positive you are very likely to be infected, particularly if you are tested during the first week of infection when you are experiencing symptoms. False negatives are a bigger concern. As with other antigen tests, BinaxNOW can miss infections, producing negative test results in people who are actually infected.

    Can You Spread The Virus If Youve Been Vaccinated

    Slow Burn: How Coronavirus Symptoms Can Start Slow, Then Worsen

    No vaccine is 100 percent effective. As such, even though the COVID-19 vaccines are highly effective at preventing COVID-19, its still possible to be fully vaccinated and contract the coronavirus. These are called breakthrough infections.

    Its still unclear exactly how common breakthrough infections are. One found that out of 1,497 fully vaccinated healthcare workers, 39 had documented breakthrough infections. Most of these infections were asymptomatic or mild.

    The coronavirus can still be transmitted to others from fully vaccinated people that contract it. Thats why its still important for fully vaccinated individuals to continue to take everyday precautions to prevent the spread of COVID-19.

    An examined the transmission of the Delta variant within households. It followed 231 contacts of 162 people with confirmed COVID-19 caused by the Delta variant. Researchers found that:

    • Vaccination lowered the risk of infection. Of vaccinated household contacts, 25 percent contracted the virus, compared to 38 percent of unvaccinated household contacts.
    • The virus can spread among vaccinated individuals. The Delta variant is transmitted from vaccinated and unvaccinated people with COVID-19 to household contacts at similar rates.
    • Vaccinated people clear the virus faster. Compared to unvaccinated people, viral loads in vaccinated individuals decreased at a more rapid rate.

    Other ways to prevent COVID-19 include:

    What Are The Symptoms Of Covid

    Some people infected with the virus have no symptoms. When the virus does cause symptoms, common ones include fever, body ache, dry cough, fatigue, chills, headache, sore throat, loss of appetite, and loss of smell. In some people, COVID-19 causes more severe symptoms like high fever, severe cough, and shortness of breath, which often indicates pneumonia.

    People with COVID-19 can also experience neurological symptoms, gastrointestinal symptoms, or both. These may occur with or without respiratory symptoms.

    For example, COVID-19 affects brain function in some people. Specific neurological symptoms seen in people with COVID-19 include loss of smell, inability to taste, muscle weakness, tingling or numbness in the hands and feet, dizziness, confusion, delirium, seizures, and stroke.

    In addition, some people have gastrointestinal symptoms, such as loss of appetite, nausea, vomiting, diarrhea, and abdominal pain or discomfort associated with COVID-19.

    When Is The Coronavirus The Most Contagious

    Researchers estimate that people who get infected with the coronavirus can spread it to others 2 to 3 days before symptoms start and are most contagious 1 to 2 days before they feel sick.

    It’s possible that, because of its shorter incubation period, you may become contagious more quickly if you have the Omicron variant. But we need more research on this.

    If You Contract Covid How Long Does It Take To Show Symptoms

    If you have symptoms that could be due to the coronavirus, consult a doctor, describe your symptoms and follow their recommendations. If you have been exposed in any case, the best option would also be a COVID-19 test on the fifth day after exposure. If you have symptoms, you should quarantine yourself until you get a negative test that shows your symptoms were not caused by COVID-19. Pay attention to or monitor your COVID-19 symptoms. If your symptoms worsen or become severe, you should consult a doctor. It varies. Most people with mild cases seem to recover within one to two weeks. However, recent investigations by the CDC have found that recovery may take longer than previously thought, even for adults with milder cases who do not require hospitalization. The CDC investigation found that one-third of these adults had not recovered within two to three weeks of testing positive for COVID-19. Among young adults who did not require hospitalization and had no underlying health conditions, nearly one in five had not recovered within two to three weeks of testing positive for COVID-19. In severe cases, recovery may take six weeks or more. If you have a fever, continue to self-isolate at home until you run out of fever. A study co-led by a researcher at Boston University`s School of Public Health found that those who were infected are the most contagious two days before and three days after symptoms appear.
