Covid-19 could be ‘swallowed’ in 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 detect infections, but researchers hadn’t looked to see why.

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

The mouth, nose, sinuses, throat, and lungs are all connected, and the virus can spread to all of these regions in mucus that is drained or coughed up. They reviewed 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, highlighting that even if the virus is cleared from the nasopharynx, the upper part of the throat behind the nose. , could persist in saliva.

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

A. This depends on the country you are in. In many parts of the world, Covid-19 vaccines are not available to pregnant women, and in some places inoculation is discouraged for breastfeeding women, due to a lack of data on these groups. In the US, the CDC has not advised pregnant and lactating women to take the vaccine, but allows them to access it, arguing that it is up to the woman how to balance the benefits and risks.

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

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

As US states relax restrictions and Americans begin to 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 various states “tells us when we have a more contagious variant that all bets are off because it means that activities that we thought were fairly low risk are now going to be higher risk,” said the analyst. CNN physician Dr. Leana Wen told CNN’s Anderson Cooper on Thursday.

EU summit becomes contentious as leaders increase pressure on AstraZeneca and the UK
