What should you do if you or someone with whom you have been in close contact tests positive for coronavirus during the holidays?
As families and friends gather over the holidays, many are looking for information on how long to quarantine, if at all and how long they might be contagious.
Here's a look at the guidance from the Centers for Disease Control and Prevention on what to do if you test positive or believe you were exposed to someone who has.
How Soon Might Symptoms Appear?
According to the CDC, COVID symptoms can appear anywhere from two to 14 days after someone is exposed to the virus.
Anyone with symptoms should get tested for COVID.
When Should You Get a COVID Test?
Those who have been fully vaccinated and around someone who has COVID-19 are recommended to get tested between five and seven days after their exposure, according to the most recent guidance from the CDC, though previous guidance had been between three and five days.
Those who develop symptoms should get tested as symptoms develop, but if a test is negative and symptoms persist another test might be needed a few days later, particularly for those who use at-home test kits.
When is Someone With COVID Contagious?
A person with COVID-19 is considered infectious starting two days before they develop symptoms, or two days before the date of their positive test if they do not have symptoms.
How Long Should you Quarantine or Isolate?
First things first, those who believe they have been in contact with someone who has COVID and are unvaccinated should quarantine. Those who test positive, regardless of vaccination status, must isolate, according to the Centers for Disease Control and Prevention.
Here's the breakdown:
Those who have been within 6 feet of someone with COVID for a cumulative total of at least 15 minutes over a 24-hour period should stay home for 14 days after their last contact with that person and watch for symptoms. If possible, those quarantining should also stay away from the people they live with, particularly those who are at an increased risk of developing more severe COVID illness.
If symptoms appear within the quarantine window, isolate immediately and contact a healthcare provider, the CDC's guidance states.
Those who are fully vaccinated do not need to quarantine, according to the CDC, but they should get tested anywhere from five to seven days following their exposure regardless of symptoms.
According to the CDC, people who are positive for COVID should stay home until it's safe for them to be around others, including even other members of their home.
Health officials recommend a "sick room" or area for those who are infected and a separate bathroom, if possible.
So how do you calculate your 10-day isolation period?
According to the CDC, "Day 0 is your first day of symptoms." That means that Day 1 is the first full day after your symptoms developed.
For those who test positive for COVID but have no symptoms, day 0 is the day of the positive test. Those who develop symptoms after testing positive must start their calculations over, however, with day 0 then becoming the first day of symptoms.
When Should You Call a Doctor?
The CDC urges those who have or may have COVID-19 to watch for emergency warning signs and seek medical care immediately if they experience symptoms including:
- 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," the CDC states. "Please call your medical provider for any other symptoms that are severe or concerning to you."
You can also notify the operator that you believe you or someone you are caring for has COVID.
What If You Test Positive Using an At-Home Test?
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.
Medical experts say that that process is not likely happening for every test, however. Positive results likely are provided to health care providers, then to the health departments.
When Can You Be Around Other People After Having COVID?
If you had symptoms, the CDC says you can be around others if you meet the following criteria:
- 10 days since symptoms first appeared and
- 24 hours with no fever without the use of fever-reducing medications and
- Other symptoms of COVID-19 are improving (note that loss of taste and smell may persist for weeks or months after recovery and do not count among these symptoms)
The CDC says these recommendations don't apply to those who have severe COVID or weakened immune systems, however.
If you tested positive but had no symptoms for the duration of your isolation, the CDC says:
- You can be with others after 10 days have passed since you had a positive viral test for COVID-19 (based on the date you were tested)
For those with severe illnesses or weakened immune systems, the CDC says staying home up to 20 days after symptoms first appeared is advised, but people in this group should talk to their healthcare provider before making decisions.
"People with weakened immune systems may require testing to determine when they can be around others," the CDC's website states. "Talk to your healthcare provider for more information."
