COVID-19 is contagious for ten days after you first notice symptoms, and for people with more severe COVID-19, the contagious period can be 20 days or more. If you suspect you have COVID-19, get tested to make sure and stay home to protect others. "Even if it's a sore throat, no matter what it is, I've told my own staff this, it's what I do myself… if you are sick, even a little bit sick, stay home," says Chicago Department of Public Health Commissioner Dr. Allison Arwady. "More true than ever right now because sick, even a little bit sick, until proven otherwise with a test – that's COVID. That's how we treat it, that's how you should treat it."

Mask mandates are being lifted, but wearing a mask in crowded indoor areas is still a highly effective way to protect yourself and other people from COVID-19—especially as you have no idea who is or isn't vaccinated, or might be contagious. "There's just been a lot of whiplash in terms of what people have been saying, because at the beginning of the pandemic, people were saying not to wear masks, and now all the health experts are saying that you should wear masks," says ob-gyn resident Pratistha Koirala, MD, Ph.D. "Medicine changes and it evolves. The more we learn about something, the better we're able to treat it."

Staying up to date with your COVID-19 vaccinations and boosters is the best way you can protect yourself from getting infected—but remember to continue using caution around large groups of people, especially indoors. "Because vaccines are not 100% effective, as the number of people who are fully vaccinated goes up, the number of vaccine breakthrough infections will also increase," the CDC advises. "However, the risk of infection remains much higher for unvaccinated than vaccinated people."

What About "Long COVID"?

Long Covid is the term commonly used when symptoms related to COVID-19 continue for months—but there's also a chance someone might be infected with a new variant such as Omicron. If you don't feel well and aren't sure if what you're experiencing is Long Covid or a new infection, get tested and use precautions such as social distancing and mask-wearing to protect the people around you. "If you have long COVID symptoms, you should seek care," says AMA member Devang Sanghavi, MD. "As we have seen in a lot of these surveys and studies about post-COVID syndrome is that usually this condition doesn't come with just one symptom—there's a cluster of symptoms. Don't label it as post-COVID right away. You want to make sure that it's not something new, and then you obviously want to make sure that your symptoms are addressed, based on the severity."

Relevant data can often be found on the local health department website or on CDC's COVID Data Tracker County View.
