![]() ![]() "Even if you've had it before, that doesn't mean your next bout is going to be the same," Cannon said. Some people who had a mild case with a first infection get hit harder the second or third time, while others might suffer less. While a previous infection provides some protection, that fades over time and as the virus evolves into different variants. To confirm the end of the contagious period, experts instead recommend a negative rapid test after 10 days or two within 48 hours if sooner. Day One is considered the first full day after symptoms start.Ī PCR test, which is considered the gold standard for diagnosing COVID-19, can remain positive for months because it detects viral fragments as well as the whole, infectious virus. The CDC recommends people isolate for at least five days and wear an N95 or similarly protective mask for at least 10 days when around others. People with COVID-19 are contagious as long as they remain positive on a rapid test, typically for about 10 days, but often longer. It takes anywhere from two to 14 days for exposure to lead to symptoms and a positive test. How long does COVID last? How long are you contagious? Peter Hotez, an infectious disease specialist and co-director of the Center for Vaccine Development at Texas Children’s Hospital. Symptoms with XBB.1.5 are the same as with earlier variants and can range from almost nothing to shortness of breath and low oxygen levels that require emergency medical attention.Įarly in the pandemic, COVID-19 often cost people their sense of taste and smell, at least temporarily, but that symptom seems less common, possibly because of vaccination or previous infection rather than a change in the virus, said Dr. What to know about XBB.1.5 symptoms and how long they lastĬOVID-19 symptoms typically last around five to seven days and can include fever, sore throat, muscle aches, exhaustion, nausea, cough and sinus congestion, among other problems. Here's a preview of what you'll learn in this article: "Reinfection buys you additional risk," he said.Īs the United States enters the fourth year of COVID-19, we're providing an update on the state of the pandemic. ![]() Every infection makes someone vulnerable to a bad course of the disease and to the lingering, miserable symptoms of long COVID, Al-Aly's research shows. It's still early and there are a lot of unknowns about XBB.1.5, he said. Louis Health Care System and a clinical epidemiologist at Washington University in St. Ziyad Al-Aly, chief of research and development at the VA St. It's a good idea to do what you can to avoid getting infected, said Dr. Its growth is probably due to XBB.1.5's characteristics – it appears to bind even more tightly to receptors in the human body than its predecessors – as well as human behavior, such as traveling and not masking. The variant is likely behind the vast majority of cases in New York and New England. ![]() 7, according to data from the Centers for Disease Control and Prevention. The latest variant, called XBB.1.5, grew exponentially over the month of December, from about 1% of cases nationwide to 27% as of Jan. But the lack of universal masking means that even people like her, who do wear masks, are vulnerable. The number of severe infections and deaths remains relatively low, despite the high level of infections, she said, thanks to vaccinations – and probably – previous infections. "All the things that have protected you for the past couple of years, I don't think are going to protect you against this new crop of variants," she said. "It's crazy infectious," said Cannon, who is recovering from her first case of COVID-19, caught when she was vacationing over the holidays in her native Britain. The newest COVID-19 variant is so contagious that even people who've avoided it so far are getting infected and the roughly 80% of Americans who've already been infected are likely to catch it again, experts say.Įssentially, everyone in the country is at risk for infection now, even if they're super careful, up to date on vaccines, or have caught it before, said Paula Cannon, a virologist at the University of Southern California. ![]()
