How much protection against the Covid 19, if both person wear a mask?

With mask on, gap of 3 feet found as effective as 6 feet

Central authorities in many countries have decided to divide the two-meter-wide, or six-foot-wide area, as between two people to prevent the spread of Covid 19.

How much protection against the Covid, if both person wear a mask?

What changes if both people wear a mask?

A study led by doctors-researchers at Beth Israel Deaconess Medical Center (BIDMC). Harvard Medical School, under investigation, found that masks had been fitted, and in the case of a school in Massachusetts, three working feet and six feet.

The study comes at a time when Massachusetts government officials have indicated that it is time to reinstate all school-age children in the classroom. It is a retrospective, global study, in which researchers compare Covid-19 PAI case rates for students and staff at Massachusetts public schools between states with universal authority but different physical distance requirement.

The team found no significant difference in the number of Covíd-19 cases among students or staff in school districts using the 3-by-six-meter separation policy between students. The findings suggest that low-level physical abuse policies can be adopted in school settings for encryption instructions without compromising student or staff safety.

In a research statement, "Previous research did not directly compare the impact of various policy differences on students in school. This study, which found significant differences in the number of cases between students or staff in school districts to implement a policy of three to six meters between students, is important because most school buildings have infrastructure. able to put six meters in the distance and return all the most) students in the class. "

Public data from 251 school districts in Massachusetts, including 537,336 students and 99,390 staff members who studied in person during the 16-week study period from September 2020 to January 2021.

Using a combination of information - including infection control plans for each region, the number of cases reported in the SEARCH Commonwealth by region, and Covid-19 community standards from the non-profit, non profit data dashboard - scientists found no significant difference in Covid-19 case scores between students and staff in districts that ordered six feet away compared to districts that ordered 3 meters from

The team's findings also showed that, in general, schools had lower rates of infection than neighbouring communities, supporting the view that internal education was not a major problem for the epidemic.

 

Vaccine alone will not fully contain virus

Vaccination of all adults in the UK is unlikely to find herd immunity and contains the full coronavirus, according to a modelling study published in the Lancet Infectious Diseases Journal. The gradual release of control measures, the introduction of high-dose vaccines, and vaccines with high protection against infection are essential to reduce future wave of infection, the authors said.

Analysis was performed prior to actual global data from vaccine excluding studies. Preliminary findings suggest that vaccination provides a level of protection against infection, but the exact level is not yet clear. For this reason, the authors have tested many levels of infection prevention.

The authors note that their model does not refer to the emergence of new variants, in which a vaccine may provide less protection, or the effects of a weakened immune system, which may require additional vaccination. They also realize that they cannot look at the effects of each other's controls.

This study showed an integrated combination of UK vaccines with a variety of measures to control rest, predict R-mortality and hospital admissions for Covid-19 from January 2021 to January 2024.

The model considered as a vaccine would be 95% for those aged 80 and over, 85% for those aged 50-79, and 75% for those aged 18-49. Immunization protection was thought to be 88% based on phase 3 trial data from Pfizer-BioNTech and Oxford-AstraZeneca vaccines offered in the UK Vaccination protection varied in four cases (0%, 35%, 60% , 85%).

According to the researchers, the findings suggest that although vaccination may significantly reduce R, it may not be enough to drive R less than 1 without some control measures. Under the most promising conditions of infection protection (85%) the number R is estimated to be 158 without further control.

Since vaccination alone is not expected for PER to call R less than 1, removing all limits after termination of vaccination is estimated to result in another vaccine with a higher mortality rate. Future wavelengths and mortality rates are influenced by how fast and timely they are measured in terms of time, level of vaccine or infection protection, and vaccination intake.

The authors look at the sudden release of certain measures (from the current limits to the situation compared to September 2020) with a vaccine that provides 85% protection and calculated the number of deaths from January 2021 to January 2024. Partial discharge in February 2021 was estimated to result in 130,100 deaths in January 2024 and a small release in April 2021 reduced this to 61,400 deaths and a partial release in June 2021 to 53,900, reflecting the impact of the immunization program. These figures all include the 49,300 deaths that have already occurred this year.
