What To Do After Exposure To Covid
After being exposed to COVID-19, you can spread the virus even if you dont show any symptoms. Quarantine keeps people who may have been exposed to COVID-19 away from other people. This helps prevent the spread of the illness.
If you need to quarantine, you should stay at home until it is safe to be around others. Learn when to quarantine and when it is safe to be around other people.
Whats The Difference Between Exposure And Infection
As with many complicated topics, its best if we start by defining our terms. What does it mean to be exposed to a virus? For purposes of contact tracing in the U.S., an exposure to COVID-19 involves having spent more than 10 minutes at less than 6 feet from someone who is infected while wearing no personal protection, says Ilhem Messaoudi, a viral immunologist at the University of California, Irvine.
Dr Frank Mcgeorge Answers Covid Questions
DETROIT Since the coronavirus pandemic began, Dr. Frank McGeorge has been keeping viewers up-to-date and informed on all fronts. Hes been answering your questions about the vaccine, the vaccination process and more.
My husband and I have breakthrough cases of COVID-19. His fever and symptoms have cleared, but mine have not. He is nearing the end of the ten days since the onset of his symptoms. Should we both quarantine until after my fever is gone?
If his symptoms have resolved and ten days have passed he can come out of his isolation. Although, you are potentially still infected. He is most likely completely resolved and no longer contagious.
How long before a person exposed to COVID can be detected in a test? If a person was exposed to someone who has COVID and gets tested two hours later, will the results be accurate?
What you want to know is how long it takes before an infected person will have a positive test. Generally, the answer is three to five days with a PCR test. Testing immediately after exposure, two hours in your example, is way too early. In fact, you arent technically even infected after two hours. The incubation period for COVID is generally at least two days.

How Do I Know If I Have Covid
COVID-19 often causes symptoms similar to those a person with a bad cold or the flu would experience. And like the flu, the symptoms can progress and become life-threatening.
So far there has been much less than the usual number of cases of influenza, likely due to the enhanced public health measures to prevent the spread of COVID.
Therefore, at the current time, people with “flulike” symptoms should assume they have COVID. That means isolating and contacting your doctor or local board of health to arrange testing.
Will I Be Contacted Will I Be Contacted On Behalf Of My Child
Yes, you may be contacted for yourself or on behalf of a dependent. Cases of COVID-19 are still reported daily across Virginia. Health departments in Virginia that are unable to perform timely follow-up of all cases and tracing of their close contacts, including children, may need to prioritize certain contact tracing and case investigations based on CDC guidance.
If you have COVID-19, you can help notify people you have been around that they may have been exposed:
- You can call, text, or email your contacts to let them know they may have been exposed to COVID-19.
- If you would like to stay anonymous, there are online tools that allow you to tell your contacts by sending out emails or text notifications anonymously at tellyourcontacts.org. You can also use an exposure notification app like COVIDWISE.
- The VDH Notify Your Contacts resource provides example messages, recommendations, and a log to help identify your close contacts.

I Received A Covidwise Exposure Notification What Should I Do
Exposure notification apps, like COVIDWISE, use bluetooth technology to support traditional contact tracing. If you receive an exposure notification from Virginias free COVIDWISE exposure notification app, that means your device was in close contact with a device of someone who recently tested positive for COVID-19. You should follow the steps to take after an exposure to stop the spread of COVID-19.
Health Equity In Sars
CDCâs COVID-19 Response Health Equity Strategy outlines a plan to reduce the disproportionate burden of COVID-19 among racial and ethnic minority populations and other population groups who have experienced a disproportionate burden of COVID-19. One component to move towards greater health equity and to stop transmission of SARS-CoV-2 is ensuring availability of resources, including access to testing for populations who have experienced longstanding, systemic health and social inequities. All population groups, including racial and ethnic minority groups, should have equal access to affordable, quality and timely SARS-CoV-2 testing â with fast turnaround time for results â for diagnosis and screening to reduce community transmission. Efforts should be made to address barriers that might overtly or inadvertently create inequalities in testing.
In communities with a higher proportion of racial and ethnic minority populations and other populations disproportionately affected by COVID-19, health departments should ensure there is timely and equitable access to and availability of testing with fast result return, especially when the level of community transmission is substantial or high.
Some strategies to achieve this goal include:

Who Is Not Required To Stay Home After Having Close Contact With Someone With Covid
- People who have had COVID-19 in the past 3 months as long as they do not develop new symptoms.*
- People who have been fully vaccinated for COVID-19 as long as they do not have symptoms.*
- Fully vaccinated people should still get tested 3 to 5 days after close contact exposure and wear a mask in public indoor settings for 14 days or until they receive a negative test.
- Fully vaccinated people who live with someone with a weakened immune system, at increased risk of severe disease, or unvaccinated could also wear a mask at home for 14 days after close contact with someone with COVID-19 or until they receive a negative test result.
S To Take After Close Contact
If you have been exposed to COVID-19, even if you are fully vaccinated, get tested for COVID-19 3-5 days after exposure and monitor for symptoms. If you are not fully vaccinated, get tested for COVID-19 3-5 days after exposure and quarantine to protect yourself, your family, and your community.
The incubation period for SAR-CoV-2, the virus that causes COVID-19, can extend up to 14 days. That means you can develop symptoms of COVID-19 sometime in the 14 days after close contact with a person with COVID-19. This is why a 14 day quarantine continues to be the safest and recommended quarantine strategy for people who are not fully vaccinated.
If you are fully vaccinated, you do not need to quarantine but you should wear a mask in public indoor spaces for 14 days or until you receive a negative test result.

Background On Case Investigations And Contact Tracing
Case investigations and contact tracing are trusted public health tools used to prevent further spread of contagious diseases. Contact tracing is not a new tool – public health uses it every day for other contagious diseases like measles and tuberculosis . Contact tracing is an important part of how Virginia can stop the spread of COVID-19.
So Which Tests To Use
Start here: There are tests that diagnose current infection and tests that show whether you previously had SARS-CoV-2, the virus that causes COVID-19.
The FDA has granted emergency use authorization for hundreds of COVID-19 diagnostic tests. This allows makers to market tests without receiving formal FDA approval because there is a public health emergency.
Because this novel coronavirus is indeed novel, and COVID-19 is a new disease, information about available tests is incomplete and testing options keep changing. Tests vary in terms of accuracy, cost, recommended use for people of various ages, and convenience. This blog post reviews features of the major types of tests. For more detailed information on individual tests, check the FDAs updated list of authorized tests, which has links to the test makers websites.

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 may 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. The virus that causes COVID-19 has also been detected in stool, which reinforces the importance of hand washing after every visit to the bathroom and regularly disinfecting bathroom fixtures.
Tests For Past Infection
An antibody test can show if you have previously been infected with the COVID-19 virus.
How is it done? A sample of blood is taken.
Where can you get these tests? At a doctors office, blood testing lab, or hospital.
What does the test look for? These blood tests identify antibodies that the bodys immune system has produced in response to the infection. While a serologic test cannot tell you if you have an infection now, it can accurately identify past infection.
How long does it take to get results? Results are usually available within a few days.
What about accuracy? Having an antibody test too early can lead to false negative results. Thats because it takes a week or two after infection for your immune system to produce antibodies. The reported rate of false negatives is 20%. However, the range of false negatives is from 0% to 30%, depending on the study and when in the course of infection the test is performed.
Research suggests antibody levels may wane over just a few months. And while a positive antibody test proves youve been exposed to the virus, its not yet known whether such results indicate a lack of contagiousness or long-lasting, protective immunity.
The Fda Extends The Johnson & Johnson Vaccines Shelf Life To Six Months
The Food and Drug Administration on Wednesday agreed to allow Johnson & Johnson to extend the shelf life of its coronavirus vaccine to six months.
The F.D.A.s decision came as state health officials in the United States were growing increasingly concerned that doses of the vaccine would expire and go to waste. The vaccines were previously set to expire after four and a half months.
In a letter, the F.D.A. said its decision was applicable to batches that might have expired prior to the issuance of this concurrence letter and had been stored at the proper temperature, 2-8 degrees Celsius, or 35.6-46.4 Fahrenheit.
The single-dose Johnson & Johnson vaccine can be stored in normal refrigeration, which has helped states reach more isolated communities where it may be difficult to manage a two-dose vaccine like those made by Pfizer-BioNTech and Moderna. Both of those must be stored at much lower temperatures.
As of Wednesday, more than 13 million Americans had received the one-shot Johnson & Johnson vaccine, according to data from the Centers for Disease Control and Prevention.
The Pfizer-BioNTech vaccine has been the most widely administered in the United States, with more than 87 million Americans fully vaccinated with it. More than 63 million people in the United States have been fully vaccinated with the Moderna formula.
Public Health Surveillance Testing For Sars
Public health surveillance is the ongoing, systematic collection, analysis, and interpretation of health-related data essential to the planning, implementation, and evaluation of public health practice. See CDCâs Introduction to Public Health Surveillance.
Public health surveillance testing is intended to monitor community- or population-level outbreaks of disease or to characterize the incidence and prevalence of disease. Surveillance testing is performed on de-identified specimens, and, thus, results are not linked to individual people. Public health surveillance testing results cannot be used for individual decision-making.
Public health surveillance testing may sample a certain percentage of a specific population to monitor for increasing or decreasing prevalence or to determine the population effect from community interventions, such as social distancing. An example of public health surveillance testing is when a state public health department develops a plan to randomly select and sample a percentage of all people in a city on a rolling basis to assess local infection rates and trends.
CDC is working with state, local, territorial, academic, and commercial partners to conduct surveillance to better understand COVID-19 in the United States and recently conducted a multistate assessment of SARS-CoV-2 seroprevalence in blood donors.

What If Im Asymptomatic And Dont Know It Could I Spread The Virus Even Beyond My 10
Theres a lot we still dont know about COVID-19, but the answer is: probably not. Although many infected people experience symptoms for two weeks or more, that doesnt mean theyre contagious the entire time they feel sick. And even if they still have symptoms and continue to test positive for the virus, that doesnt necessarily mean theyre contagious. I know that last part is particularly confusing. Lets unpack it.
A viral infection ends once your body kills all remaining functioning viruses, putting an end to their replication. Your immune system takes no prisoners when it goes to task, Messaoudi says. After the interferon alarm goes off, what she calls the heavy artillery arrive: a dramatic burst of T-cells that go around killing all the cells in your body that are harboring virus. You start out with 100 to 500 T-cells and in three to four days you expand to millions of cells, she says. Quite the dramatic ramp-up.
For Pitzer, best practices would be getting tested on day 3 or 4 after an exposure and then again between days 7 and 10. Messaoudi and Lee recommend similar timelines.
Even if that attack is successful and there arent any more infected cells to kill, theres plenty of bits of virus floating around in the chaosmanufacturing errors that wont ever replicate, pieces of genetic material left over from the inside of cells that died.
Who Are Case Investigators And Contact Tracers
Case investigators and contact tracers are skilled, trained public health professionals. They find people who test positive for an infection or might have been exposed and provide guidance on how to stop its spread.
The Virginia Department of Health has been working hard to conduct case investigations and contact tracing since the beginning of the COVID-19 response. It is important for community members to trust these public health professionals, respond to their outreach, and follow their guidance to stop the spread of COVID-19.

When You Are Fully Vaccinated And Traveling Internationally
International travelers need to pay close attention to the situation at their international destinations before traveling due to the spread of new variants and because the burden of COVID-19 varies globally.
- Fully vaccinated travelers do not need to get tested before leaving the United States unless required by their destination.
- Fully vaccinated air travelers coming to the United States from abroad, including U.S. citizens, are still required to have a negative SARS-CoV-2 viral test result or documentation of recovery from COVID-19 before they board a flight to the United States.
- International travelers arriving in the United States are still recommended to get a SARS-CoV-2 viral test 3-5 days after travel regardless of vaccination status.
- Fully vaccinated travelers do not need to self-quarantine in the United States following international travel.
- For more information, see International Travel During COVID-19.
What To Do If My Covid Test Comes Back Positive
If your first test is positive, you need to self-isolate at home for 14 days, even if youre not exhibiting any symptoms. During this time, follow all best practices to slow the spread:
- Remain in a closed room if you dont live alone .
- Wear a mask when using a shared bathroom at your home.
- Notify people you may have recently been in contact with.
