If you live in the same household as a person who has symptoms of coronavirus or who has received a positive test result, follow the Stay at Home: guidance for households with possible or confirmed COVID-19.

If you have been in close contact with, but do not live with, a person who has tested positive for COVID-19, follow the guidance below.

Can People Without Symptoms Spread The Virus To Others

“Without symptoms” can refer to two groups of people: those who eventually do have symptoms and those who never go on to have symptoms . During this pandemic, we have seen that people without symptoms can spread the coronavirus infection to others.

A person with COVID-19 may be contagious 48 hours before starting to experience symptoms. In fact, people without symptoms may be more likely to spread the illness, because they are unlikely to be isolating and may not adopt behaviors designed to prevent spread.

But what about people who never go on to develop symptoms? A published in JAMA Network Open found that almost one out of every four infections may be transmitted by individuals with asymptomatic infections.

We are learning that people who are vaccinated are less likely to infect others. However, even people who are fully vaccinated can carry greater amounts of the Delta variant , making it more likely that they could spread the virus to others. Thats one reason why, in July 2021, the CDC advised people who are fully vaccinated to wear masks in public indoor places in areas of the country with substantial or high transmission of the virus.

People who are not vaccinated remain at increased risk for becoming infected and infecting others. For this group, the CDC continues to recommend mask wearing and other preventive measures in some outdoor settings and in most indoor settings.

Caring For Someone Sick At Home

Advice for caregivers in non-healthcare settings

If you are caring for someone with COVID-19 at home or in a non-healthcare setting, follow this advice to protect yourself and others. Learn what to do when someone has symptoms of COVID-19 or when someone has been diagnosed with the virus. This information also should be followed when caring for people who have tested positive but are not showing symptoms.

*Note:Older adults and people of any age with serious underlying medical conditions are at higher risk for developing more severe illness from COVID-19. People at higher risk of severe illness should call their doctor as soon as symptoms start.

    Close Contact With Someone With Covid

    You are more likely to get COVID-19 if you are in close contact with a person who has COVID-19 while they are contagious or still able to spread illness to others.

    Close contact means:

    • Being within 6 feet of a person who has COVID-19 for a total of 15 minutes or more over a 24-hour period, or
    • Having direct exposure to respiratory secretions , or
    • Caring for a person who has COVID-19, or
    • Living with a person who has COVID-19.

    Exception: In K-12 settings, a student who was within 3 to 6 feet of an infected student is not considered a close contact as long as both students wore well-fitting masks the entire time. VDH expanded CDCs K-12 exception to include both indoor and outdoor settings. This exception does not apply to students on school buses. This exception also does not apply to teachers, staff, or other adults.

    People with COVID-19 can pass the COVID-19 virus to their close contacts starting from 2 days before they become sick until it is safe to be around other people .

    People who have had close contact with someone who has COVID-19 need to stay home and away from others. This is called quarantine.

    • There are some exceptions where people are not required to quarantine . These exceptions are described below.

    How Long Can Covid

    UPDATE: After being exposed to COVID

    Its uncertain how long COVID-19 can survive on surfaces, but it seems to behave like other coronaviruses. This means it can survive on surfaces for a few hours or, under some circumstances, for up to several days. This could depend on which type of surface it is, or on the temperature or level of humidity of the environment.

    If you think a surface may be infected, clean it with a common household disinfectant to kill the virus and protect yourself and others. Wash your hands with soap and water or clean them with an alcohol-based hand rub. Avoid touching your eyes, mouth and nose.

    Scientists Used Chinese Data

    To predict the order of symptoms, researchers analyzed rates of symptom incidence collected by the World Health Organization for over 55,000 confirmed COVID-19 cases in China.

    They also looked at a data set of almost 1,100 cases collected between December 2019 and January 2020 by the China Medical Treatment Expert Group for COVID-19 and provided by the National Health Commission of China.

    To compare the order of COVID-19 symptoms to influenza, the researchers analyzed data from over 2,000 influenza cases in North America, Europe, and the Southern Hemisphere reported to health authorities between 1994 and 1998.

    The order of the symptoms matter, said Joseph Larsen, lead study author and USC Dornsife doctoral candidate. Knowing that each illness progresses differently means that doctors can identify sooner whether someone likely has COVID-19, or another illness, which can help them make better treatment decisions.

    According to the studys findings, this is the order of symptoms that people with COVID-19 can experience:

  • fever
  • nausea or vomiting
  • diarrhea
  • The study found that patients with seasonal flu more commonly developed a cough before the onset of fever, Dr. Robert Glatter, emergency physician at Lenox Hill Hospital in New York, told Healthline. In reality, this may be difficult to discern since the flu often begins abruptly with a triad of symptoms, including back pain, chills, along with a dry cough.

    Some Could Show Covid

    March 10, 2020 –Although a 14-day quarantine after exposure to the new coronavirus is “well supported” by evidence, some infected people will not show symptoms until after that period, according to authors of a recent analysis published in Annals of Internal Medicine.

    Most people who have COVID-19, the disease caused by the new coronavirus, will get symptoms by day 12 of the infection, which is within the 14-day period of quarantine the CDC recommends, the authors wrote.

    But about 101 out of 10,000 people could show symptoms after the end of that 14-day monitoring period, they cautioned.

    “Our analyses do not preclude that estimate from being higher,” said the investigators, led by Stephen A. Lauer, PhD, of Johns Hopkins Bloomberg School of Public Health in Baltimore.

    The analysis, based on 181 confirmed cases of COVID-19 documented outside the outbreak epicenter in Wuhan, China, makes “more conservative assumptions” about how long it takes symptoms to appear and the potential for continued exposure, compared to previous studies, the researchers wrote.

    The estimated incubation period for the new coronavirus in the 181-patient study was a median of 5.1 days. That is comparable to previous estimates of COVID-19 cases outside Wuhan and consistent with other known human coronavirus diseases, such as severe acute respiratory syndrome , which had a reported mean incubation period of 5 days, Lauer and colleagues noted.

    July 21, 2021: Since this article was originally published, new variants of the SARS-CoV-2 virus have become prevalent. Vaccination continues to be highly protective against serious illness, hospitalization, and death, even with the more transmissible Delta variant. But weve changed some of our recommendations about masking and other precautions for vaccinated individuals in certain situations, even when precautions are not required. Read more.

    How long before COVID-19 symptoms appear is a person contagious? In other words, based on the day a person actually becomes ill, how far back should contact tracing go?

    While the incubation period for the virus can be as long as 14 days, research suggests that people who are infected with SARS-CoV-2, the virus that causes the COVID-19 illness, may become infectious to others several days before they start to feel ill.

    For this reason, the Centers for Disease Control and Prevention considers contact tracing to be crucial in protecting communities from further spread of the virus. Time is of the essence, they state. 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 If I Want To Travel Abroad

    Whether youre fully vaccinated or not, youll need to do some prep work. First, find out if the country youre going to has entry requirements or restrictions. Youll need to follow all of its requirements, or you may get sent home. Also ask your airline about its requirements for COVID-19 testing and paperwork.

    You should also find out whether COVID-19 is spreading in the country you plan to visit. Take a look at the CDCs COVID-19 Travel Recommendations by Destination to find the current level of risk.

    If youre not fully vaccinated, get a COVID-19 test in time to have your result 1 to 3 days before you travel. If youre fully vaccinated, you dont need to get tested beforehand unless the place youre traveling to requires it.

    Flying back to the U.S. is a different story. Everyone — even fully vaccinated people — must get a negative COVID-19 test result no more than 3 days before they travel and be able to show that result to airline officials before they get on their flight. Or they must be able to show proof that theyve had the virus and recovered within the past 3 months. The precautions for returning travelers are in place because of the COVID-19 variants still spreading around the world.
