Covid patients with these types release the virus the most: Study. details inside

A research has shown that covid infected patient Those who have received their vaccination dose, including a booster dose, release the virus into the air, posing a risk to others. The study also showed that patients infected with alpha, delta and Omicron variants release more virus than those infected with other variants.

John Volkens, a public-health engineer at Colorado State, says, “This research has shown that all three types of infections that win the race are cleared out of the body more efficiently when people talk or shout compared to early strains of the coronavirus.” Huh.” University at Fort Collins.

Here is the detailed understanding of the study

how the study was conducted

The work was posted on the medRxiv preprint server on July 29. It has not been peer reviewed yet.

-For the study, Coleman and his colleagues recruited 93 people who were infected between mid-2020 and early 2022. SARS-CoV-2,

-Participants’ infections were caused by strains including the alpha variant, and later the delta and omicron variants. All participants with the latter two strains were fully vaccinated before catching the virus.

-Infected people faced a cone-shaped device and sang and shouted – accompanied by inevitable coughs and sneezes – for 30 minutes, while an attached machine collected the particles they expelled. The device, called Gesundhit-II, separated fine ‘aerosol’ droplets of 5 micrometers or less in diameter, which can remain in the air and leak through clothing and surgical masks.

what the study found

-The team found that the participant is infected with Alpha, Delta and Omicron Variants emit significantly more viral RNA during exhalation than those infected with other types.

-These include ancestral variants, such as those first detected in Wuhan, China, and that are not associated with increased transmissibility – such as Gamma, which arose in late 2020.

For participants with -Delta and Omicron, their finer aerosols contained an average of five times the amount of virus found in their larger, thicker aerosols.

The study also highlights variation between individuals in the amount of exhaled virus, ranging from non-detectable levels to those associated with ‘superspreaders’. For example, an oomicron-infected participant shed 1,000 times as much viral RNA through fine aerosols as the maximum levels seen in people with alpha or delta.

Researchers say the root of these discrepancies remains a mystery but may be related to biological factors such as a person’s age. Behavior may also play a role: The study’s superspreaders coughed more often than others.

Expert took data of Kovid-19 study

Study co-author Kristen Coleman, who researches emerging infectious diseases at the University of Maryland in College Park, says this means that people need to “instruct governments to invest in improving indoor air quality by improving ventilation and filtration systems.” should be inspired”.

If the new variants have a high risk of superspreading, it could lead them to dominate the Covid-19 cases. The team noted that people infected with SARS-CoV-2 exhale much smaller amounts of viral RNA than people infected with influenza, a comparable airborne illness. This suggests that SARS-CoV-2 can spin off variants that transmit even more viruses.
