Scientists are closely watching an Omicron subtype spreading in Denmark, the UK, Singapore and India

BA.2 is harder to detect on lab tests than BA.1.Leon Neal/Getty Images Scientists worldwide are closely tracking an Omicron subtype, called BA.2. In Denmark BA.2 is surpassing the BA.1 Omicron subtype, the most common cause of new COVID-19 cases. It's not yet clear if BA.2 will be more severe or contagious than BA.1. Health officials and scientists worldwide are closely watching a subtype of the highly infectious Omicron COVID-19 variant.The new subtype, called BA.2, is a sister to BA.1 —...

Early evidence suggests Omicron infection could give people 'superimmunity' against future coronavirus variants, but experts warn COVID-19 is still unpredictable

A stock image of a man receiving a vaccination in his arm.Getty Images The combination of vaccination and immunity from natural infection produces strong protection, data suggest. Most data we have is from the time when Delta was dominant, but emerging evidence suggests the same could be true for Omicron. Exposure to Omicron and other variants may diversify the immune response to any strain of the virus. As people rack up boosters and breakthroughs, immunity has become a complicated buzzword ...

Here's how long people with COVID-19 may remain contagious, according to the best available data

People clear the virus at different speeds so the length of time infected varies.Ben Hasty/MediaNews Group/Reading Eagle/Getty Images UK health officials estimated the impact of different isolation periods on COVID-19 infectiousness. Five days from symptoms or a positive test, 31% of people with COVID-19 were contagious, they said. Testing negative on rapid tests on days 5 and 6 cut the risk of being infectious to 7%, they said. It's a critical question that has played on the minds of ind...

Striking new data shows vaccines have protected New Yorkers very well against Omicron so far

A graph shows cases of COVID-19 per 100,000 people in NYC. Recent data may be incomplete.NYC Health Data from New York City's Department of Health shows vaccinated people largely avoided Omicron. When COVID-19 cases spiked in early January, unvaccinated people were far more likely to get sick. Most people who have been hospitalized or died of COVID-19 were not vaccinated. The arrival of the Omicron variant created a sense of unease for most New Yorkers. But according to recent data from N...

One chart shows how well vaccines and boosters protect against severe Omicron compared to Delta

Jolanta Gawlik, left, gives Juliana Cepeda the Pfizer COVID-19 vaccine in New York.Mark Lennihan/AP Photo Booster shots appear to be at least 90% effective against hospitalization for Delta and Omicron. But Omicron poses a greater challenge to vaccine protection, according to two new CDC studies. Omicron increased the odds that vaccinated or boosted people would get infected relative to Delta. COVID-19 booster shots were effective at preventing hospitalization and death before Omicron started...

CDC report finds prior infection provided strong protection against COVID-19 in 2021, but experts warn it's 'playing with dynamite' to get sick on purpose
