Covid-19 could be 'swallowed' into our bodies - Coronavirus Fact vs Fiction


The study, detailed in the journal Nature Medicine on Thursday, may explain why so many infected people lose their sense of taste and suggests that the mouth is a major source of the spread of Covid-19. Saliva tests were previously known to be a good way to spot an infection, but researchers hadn’t looked to see why.

“When infected saliva is swallowed or tiny particles are inhaled, we believe it can potentially transmit SARS-CoV-2 further into our throats, lungs or even guts,” said Dr Kevin Byrd from the American Dental Association Science and Research Institute, which worked on the study.

The mouth, nose, sinuses, throat, and lungs are connected, and the virus can spread through all of these areas in mucus that drains or is coughed up. They checked oral tissue samples from people who died from Covid-19 and found the virus in about half of the salivary glands they tested.

The study also found evidence that people who test negative after a nasal swab sometimes continue to test positive on a saliva test, pointing out that even though the virus is cleared from the nasopharynx – the upper part of the throat behind. the nose – it might linger in saliva.

Q. Can pregnant or breastfeeding women be vaccinated against Covid-19?

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

A new study suggests that the Pfizer / BioNTech and Moderna Covid-19 vaccines widely used in the United States are at least effective for these women and even their unborn babies. Researchers at Massachusetts General Hospital, Brigham and Women’s Hospital, and the Ragon Institute at MGH, MIT, and Harvard examined 131 women who received either vaccine. The antibody levels induced by the vaccine were equivalent in pregnant and lactating women, compared to non-pregnant women, according to the study. The team also found that breastfeeding women passed protective antibodies to their newborns.

Dangerous variants could mean ‘all bets are off’ on US recovery

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

An increase in the number of infections in several states “tells us that when we have a more contagious variant, all bets are off, because that means activities that we thought were low risk are now going to be riskier,” explains the Dr. Leana Wen told CNN’s Anderson Cooper Thursday.

Dr Rochelle Walensky, director of the United States Centers for Disease Control and Prevention, also warned on NBC’s “Today” show that the United States “still suffers about 1,000 deaths a day”, which is “too much”.

President Joe Biden doubles vaccination target for first 100 days

The United States has one of the fastest vaccination deployments in the world, with 133 million doses already administered. Building on that momentum, President Biden said Thursday his administration aims to deliver 200 million doses by the end of April, doubling his original target.

“I know it’s ambitious – twice our original target – but no other country in the world has even come close to what we’re doing. I think we can do it,” Biden said.

EU summit sinks into feuds as leaders pressure AstraZeneca, UK

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

At the virtual meeting, European Union leaders confirmed their intention to allow a vaccine export ban in certain situations to prevent doses from leaving the shores of the bloc, as it struggles to deploy a generalized vaccination program.

TODAY’S PODCAST

“Only once we’ve really got through this period of striving to improve voluntary membership, then should we start to think mandates are necessary and appropriate.” – Emily Largent, lawyer and assistant professor of medical ethics.
