Yes, COVID-19 is still circulating. The virus that causes it, SARS-CoV-2, continues to infect people worldwide, causing illness that ranges from mild cold-like symptoms to severe disease and long-term health effects. While the emergency phase of the pandemic is over, COVID has not disappeared. It has settled into a pattern of ongoing transmission, with new variants emerging regularly and updated vaccines released each year to keep up.
How COVID Looks Now Compared to 2020
The situation today is fundamentally different from the early pandemic. In the prevaccination period of 2020, roughly 5.7% of confirmed cases led to hospitalization, and the overall fatality rate was about 1.7%. For people over 85, nearly one in four confirmed cases was fatal. Those numbers have dropped substantially thanks to widespread immunity from both vaccination and prior infection, plus the availability of antiviral treatments.
COVID still sends people to the hospital and still causes deaths, but at far lower rates than during the worst waves. Older adults (especially those 75 and up), people with chronic lung or heart disease, those with weakened immune systems, and people who are unvaccinated remain at the highest risk for severe outcomes.
The Virus Keeps Changing
SARS-CoV-2 continues to mutate, producing new variant lineages that the CDC tracks through genomic surveillance. The variant landscape shifts every few months. As of early 2026, the dominant lineages in the U.S. include XFG.1.1 (about 32% of cases), XFG (13%), and several other sublineages, none of which are the same strains that circulated even a year earlier. This constant evolution is one reason COVID hasn’t gone away: the virus changes enough to partially dodge existing immunity, which allows reinfections.
No Clear Seasonal Pattern Yet
Unlike the flu, which reliably peaks in winter, COVID hasn’t settled into a predictable seasonal cycle. Research comparing the two viruses in Europe and the U.S. found that while COVID activity did spike alongside flu season, it also remained elevated well beyond winter months. This means waves of infection can happen at any time of year, making it harder to predict when risk is highest.
Current Symptoms
The symptoms of current COVID strains overlap heavily with other respiratory viruses. The CDC’s current list includes fever or chills, cough, sore throat, congestion or runny nose, fatigue, muscle aches, headache, shortness of breath, nausea or vomiting, diarrhea, and loss of taste or smell. Symptoms typically appear 2 to 14 days after exposure. Many people describe recent infections as feeling like a bad cold, though severity varies widely from person to person.
Emergency warning signs that call for immediate medical attention include trouble breathing, persistent chest pain or pressure, new confusion, and inability to stay awake.
Home Tests Still Work, With Limits
Over-the-counter rapid antigen tests can still detect COVID, but they’re far from perfect. Real-world studies have found their overall sensitivity hovers around 59%, meaning they miss a significant number of infections. The catch is that accuracy depends heavily on how much virus is present. When viral load is high (early in a symptomatic infection), rapid tests match lab results about 90% of the time. As viral load drops, sensitivity plummets, falling to as low as 5% in people with very low levels of virus.
The practical takeaway: a positive home test is reliable. A negative one, especially early after exposure or when symptoms are mild, doesn’t rule out infection. Testing again 24 to 48 hours later improves your chances of catching it.
Updated Vaccines and Who Should Get Them
COVID vaccines are updated annually, similar to the flu shot. The 2025–2026 vaccine is recommended for everyone 6 months and older, with the strongest recommendation for people at higher risk of severe illness. Adults 65 and older are advised to get two doses; most other people need just one.
For young children who have never been vaccinated, the initial series may require two doses depending on age. The CDC frames vaccination for people aged 6 months through 64 as an individual decision, noting that the benefit is greatest for those with risk factors like chronic disease or immune suppression, and lowest for healthy younger adults.
Treatment Options If You Get Sick
Several antiviral medications are available for people at higher risk of severe COVID. Paxlovid is approved for adults and children 12 and older. Remdesivir can be used in adults and children of any age. Molnupiravir is available for adults. All three are designed to treat mild to moderate illness in people more likely to develop serious complications, including older adults, people with certain chronic conditions, and those who aren’t up to date on vaccination.
These treatments work best when started early, ideally within the first few days of symptoms. If you test positive and fall into a higher-risk group, contacting a healthcare provider quickly matters.
What to Do After a Positive Test
The CDC simplified its isolation guidance in 2024, aligning COVID recommendations with those for other respiratory viruses. You can return to normal activities once your symptoms have been improving for at least 24 hours and any fever has been gone for a full day without fever-reducing medication. After resuming your routine, the guidance encourages five additional days of precautions: wearing a well-fitting mask around others, improving ventilation, keeping distance when possible, and practicing good hand hygiene.
Long COVID Remains a Concern
Some people develop persistent symptoms after a COVID infection, a condition known as long COVID. There is no diagnostic test for it, and prevalence estimates vary widely depending on how studies define and measure symptoms. What’s clear is that long COVID affects a meaningful number of people across all age groups, with symptoms that can include fatigue, brain fog, shortness of breath, and other issues lasting weeks or months. Updated prevalence data broken down by demographics and geography is expected from the CDC by late 2026.
