Nose and throat samples collected from children with COVID-19 contain as much virus as those taken from infected adults, suggesting they may be just as contagious, a study published Friday by JAMA Pediatrics found.

The United States will spend $3.5 billion to buy and donate 500 million doses of the Pfizer (PFE.N) coronavirus vaccine to some of the world’s poorest countries, it said on Thursday, urging other G7 nations to follow suit.

Automated software that simulates people is the primary driver of COVID-19 misinformation, a study finds.

Scientists say that two common strains of the seasonal flu have seemingly vanished from circulation, likely due to public health measures like mask-wearing meant to slow the covid-19 pandemic. Though it will take time to confirm the disappearing act, the unexpected good news could make developing next season’s flu shot all the easier.

The messenger RNA technology used to make Moderna's and Pfizer/BioNTech's wildly successful coronavirus vaccines is being tested not only in other vaccines, but as a cancer treatment, gene therapy and more.

Air pollution has long been one of the most severe forms of environmental damage.

While it may have been hard to meet new people over the past 14 months, many Americans sought out new relationships through the faces on their TV screens—connected TV screens, that is.

The COVID-19 pandemic is shifting the shape of population in countries around the world, both in lives lost and in babies not born. We are becoming fewer even faster than before. More than a year after governments closed borders, shut down businesses and ordered people to stay home, the latest data show significant declines in fertility in some countries – declines that could become permanent. At the other end of life, so many people have died prematurely that life expectancy has gone down in some countries. This pandemic will influence the demographic makeup of countries, including Canada, for years to come.

One coronavirus survivor manages her medical bills in color-coded folders: green, red and tan for different types of documents.

Of the three kinds of people that exist in 2021, two - people who wear masks properly and people who don't wear them at all, are not very interesting. The former are doing what everyone should be and the latter will win their very own Darwin Awards someday. However, the third kind are rather perplexing. They wear masks on their face but don't bother to cover their noses and/or mouths with it. What's unique about these folks?

The number of Americans seeking unemployment benefits fell to 498,000 last week, the lowest level since the viral pandemic struck 14 months ago and a sign of the job market’s growing strength as businesses reopen and consumers increase spending.
