The chief doctor of one of the hospitals – a specialist paediatric facility – told the BBC that “our hearts were in our mouths” because of the risk of children dying. They got supplies just in time, after a local politician intervened.
A new study estimates that the number of people who have died of COVID-19 in the U.S. is more than 900,000, a number 57% higher than official figures. Worldwide, the study’s authors say, the COVID-19 death count is nearing 7 million, more than double the reported number of 3.24 million.
Rohan Aggarwal is 26 years old. He doesn’t even complete his medical training until next year. And yet, at one of the best hospitals in India, he is the doctor who must decide who will live and who will die when patients come to him gasping for breath, their family members begging for mercy.
Viruses need entry proteins to penetrate the cells where they will replicate. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) version is called the spike or S protein. The S protein, also the target of the current vaccines, is quickly adapting to its new human hosts. It took its first major step in this direction early in 2020, when its amino acid 614 (of 1297) changed from an aspartic acid (D) to a glycine (G). Viruses bearing this D614G mutation transmit among humans more rapidly and now form the majority in circulation. On page 525 of this issue, Zhang et al. (1) use careful structural analyses to reveal how D614G changed the S protein to accelerate the pandemic.
Slow global COVID-19 vaccination rates are raising concerns that worse variants of the coronavirus could be percolating, ready to rip into the world before herd immunity can diminish their impact.
Dr. Francis Collins, director of the National Institutes of Health, said on ABC’s Good Morning America Wednesday he’s hopeful the US Food and Drug Administration will greenlight Covid-19 vaccines for 12- to 15-year-olds and it will be important to start vaccinating high school-age people well in advance of the fall.
Base camp officials said they had received reports of 17 confirmed cases from hospitals in the capital Kathmandu, where a number of climbers have been sent from the base camp and higher camps to be treated.
To understand how risky it may be to board a flight now, start with how air circulates in a plane.
Researchers from Mount Sinai Hospital in New York City, NY, believe that a combination of drugs already approved for use in the United States could be the key in treating COVID-19.
A study from researchers in Brazil provides a more robust answer to at least one key question: can vitamin D help prevent COVID-19 complications in particularly ill hospitalized patients? According to the results, the answer appears to be no.
As India’s massive coronavirus wave spreads, neighboring Nepal is also quickly becoming overwhelmed. An average of 6,700 cases are now reported a day as of May 5, an increase from 1,100 just two weeks earlier. Even as the country faces its steepest coronavirus wave yet, it has kept its main tourist attraction, the Nepali side of Mount Everest, open to foreigners seeking to climb the world’s tallest mountain.
The road to eliminating Covid-19 is long and paved with uncertainty. Many countries are counting on vaccines to build sufficient immunity in their populations so that SARS-CoV-2 isn’t able to find susceptible people to infect, causing transmission of the coronavirus to slow and eventually stop. But even with the rollout of highly effective vaccines, immunization coverage may not reach that level — the so-called herd immunity threshold — anytime soon. For one thing, it’s not known what level of immunity is required. There’s also the threat of emerging coronavirus variants that may weaken the effectiveness of immunizations.
The Pfizer-BioNTech coronavirus vaccine provides strong protection against two concerning variants of the virus, including the one that has most worried scientists because it can evade parts of the immune response, according to new data from Qatar.
The world is fast becoming ever more reliant on China for vaccines, with India’s raging virus outbreak stifling its ability to deliver on supply deals, even as the U.S. tries to position itself as a champion of wider access.
Typically, if you get a COVID-19 vaccine that requires two doses, you should get two of the same vaccine. Two Pfizer shots, or two Moderna shots. Not one and then the other. But in the future, that could change, either by necessity or by design.
As the Seychelles began to offer free coronavirus vaccinations early this year, President Wavel Ramkalawan told reporters that the country was planning to reach herd immunity within weeks. It was an ambitious target for a small, geographically isolated island nation in the Indian Ocean. But with its economy heavily reliant on tourism, the country called in favors to attain a vaccine supply from regional allies, including India and the United Arab Emirates.
It’s been six months since the first COVID-19 vaccine was administered in the U.S. and now almost 40% of the country’s population is fully vaccinated.
A COVID-19 vaccine from French company Valneva has yet to complete clinical trials. But it has caught the eye of governments in the UK, Europe and Australia.
The development from the Biden administration draws cheers from public-health researchers and ire from drugmakers.
Japan’s government may approve the use of coronavirus vaccines developed by AstraZeneca and Moderna Inc as early as May 20, the Nikkei reported on Friday. Health ministry officials plan to hold a meeting around that date to discuss approval, the financial daily reported.
When Ziyad Al-Aly’s research team told him how often diabetes appeared to strike Covid-19 survivors, he thought the data must be wrong, so he asked his five colleagues to crunch the numbers again.

Exhaustion is also one of the top complaints she hears from her patients these days. They say things like, “It’s just so hard to get out of bed” or “I’ve been misplacing things more often,” she says.
Some people said they started bathing less during the pandemic. As long as no one complains, they say they plan to keep the new habit.
