Covid-19 could “swallow” our bodies: made of coronavirus and fiction

by

The study, detailed Thursday in the journal Nature Medicine, may explain why so many infected people lose their sense of taste and suggest that the mouth is an important source of Covid-19 spread. Saliva tests were previously known to be a good way to detect infection, but researchers had not looked at why.

“When swallowing infected saliva or inhaling small particles, we believe it can transmit more SARS-CoV-2 to the throat, lungs or even the intestines,” said Dr. Kevin Byrd of the American Dental Association Science and the Research Institute, which worked on the study.

The mouth, nose, paranasal sinuses, throat and lungs are connected and the virus can spread to all those regions of the mucus that drains or coughs. They checked oral tissue samples from people who died of Covid-19 and found the virus in about half of the salivary glands they tested.

The study also found evidence that people who give negative tests after a nasal swab sometimes continue to test positive in a saliva test, noting that even if the virus is removed from the nasopharynx (the upper part of throat behind the nose) could persist in saliva.

Q. Can pregnant or lactating women receive a vaccine against Covid-19?

A. It depends on the country where you are. In many parts of the world, Covid-19 vaccines are not available for pregnant women and it is recommended that breastfeeding women not be inoculated due to the lack of data on these groups. In the United States, the CDC has not advised pregnant and lactating women to take the vaccine, but allows them to access it, arguing that it is the woman’s decision on how to balance the benefits and risks.

A new study suggests that the Pfizer / BioNTech and Modern Covid-19 vaccines that are widely used in the United States are at least effective for these women and even for their babies. Researchers from Massachusetts General Hospital, Brigham and Women’s Hospital and the Ragon Institute of MGH, MIT and Harvard examined 131 women who received any of the shots. Vaccine-induced antibody levels were equivalent in pregnant and lactating women, compared with nonpregnant women, according to the study. The team also found that breastfeeding women transmitted protective antibodies to their babies.

Dangerous variants can mean that “all bets are off” on the U.S. recovery

As U.S. states relax restrictions and Americans travel again, medical experts warn that the pandemic is far from over and that new variants threaten to derail progress in the country.

An increase in the number of infections in several states “tells us when we have a more contagious variant that all bets are off because it means that activities we thought were quite low will now have a higher risk,” the medical analyst said. from CNN, Dr. Leana Wen told Anderson Cooper on CNN on Thursday.

Dr. Rochelle Walensky, director of the U.S. Centers for Disease Control and Prevention, also warned on NBC’s “Today” show that the U.S. “continues to see about 1,000 deaths a day,” which is “too much.”

President Joe Biden doubles the vaccine target for the first 100 days

The United States has one of the fastest vaccination sites in the world, with 133 million doses administered. Based on that impetus, President Biden said Thursday that his administration aimed to administer 200 million doses by the end of April, doubling its initial target.

“I know it’s ambitious, double our original goal, but no other country in the world has even come close, not even close to what we’re doing. I think we can do that,” Biden said.

EU summit falls into dispute as leaders pressure AstraZeneca and UK

A summit that is supposed to push pharmaceutical company AstraZeneca to speed up deliveries of tens of millions of vaccines and pressure the UK to share doses made in the country was hijacked by Austrian Chancellor Sebastian Kurz, who demanded a higher proportion of shots for his people. , creating an internal fracture in the block.

European Union leaders at the virtual meeting confirmed their plans to allow a ban on vaccine exports in some situations to prevent doses from coming off the shores of the bloc as it struggles to deploy a widespread vaccination program .

TODAY’S PODCAST

“Only once this period has really passed in which we have tried very hard to improve voluntary recruitment should we begin to think that mandates were necessary and appropriate.” – Emily Largent, lawyer and adjunct professor of medical ethics.

Suppressing the spread of Covid-19 in the United States will require vaccinating 70-85% of the population. But what if there aren’t enough Americans against the vaccine? CNN’s chief medical correspondent, Dr. Sanjay Gupta, talks to Largent about a controversial published proposal: to force vaccines. Listen now.
