Good Lifestyle

Early in thecoronavirus pandemicWe were very focused on disinfection of everything to avoid capturing Covid, but we learned a lot about the virus since then. On the one hand, disease control and prevention centers (CDC) now believe that there is little risk ofCoronavirus Contracting Surfaces. For another, experts came to understand thatCoronavirus is airborne, which means we should focus on ventilation. In fact, remembering three words could be the key to avoiding situations where you are most likely to contract COVID:Location, Ventilation and Vocalization.

Talk toAtlantic, infectious epidemiologist of diseasesSaskia Popescu, PhD, emphasized the importance ofFocus on super-spreader events (SSE) rather than people who could beCalled Supersfeaders. It has already been reported that 97% ofSSE takes place insideBut all interior spaces are not created equal. This is where all three comeMediocre ventilation halls And an excessive vocalization of the crowd are more likely to lead to an epidemic of coronavirus.

"Most super-spreader events occur in an indoor location, including a little ventilated (sense of air is not exchanged, diluted or filtered), where many people speak, sing or sing"Atlantic reports. "Some examples of super-spreader events have occurred are restaurants, bars, clubs, choir practices, weddings, funerals, cruise ships,retirement homes, prisons and meat plants. "

Remember the three V is another easy way to decide whichEvents are sufficiently sure to participate inand which should be avoided. The CDC previously suggested a similar mnemonic device, the three C's, as a means ofEvaluate the risk of COVID infection In a given situation: closed spaces with low ventilation, crowded places and narrow contact parameters.

The key addition of the three V is the "vocalization". Several studies have shown that coronavirus is transmitted viaDroplets infected with infected people When we talk or even breathing. But speaking strong and singing can spread even more droplets, which then have the ability to linger in the air, especially in interior spaces with inadequate ventilation. That is whybars and churches Also proved at high risk: screaming on strong music or singing in a choir are both intense vocalizations.

In this spirit, you focus on ventilation can be one of the best paths forward towards the slowdown in the propagation of coronavirus. Paraphrase virginia tech professorLinsey Marr, PhD,Atlantic Notes: "If aerosols are crucial, we should focus as much on the ventilation we do on distancing, masks and handwashing, that all expert agreements are important."

In an OP-ED forThe New York Times, Marr explained ways ofimprove ventilation: "Open windows and doors. Adjust the shock absorbers in the air conditioning and heating systems. Upgrade the filters of these systems. Add portable air cleaners or install germicide ultraviolets to eliminate or kill virus particles in the air."

These are just some of the things that businesses, schools and even you at home can do forimprove ventilation and thus significantly reduce the risk of covid propagation. But in the meantime, the three V can at least help you decide on the places and activities that you can visit safely and participate in and allows you to avoid escaping the process. And for more coronavirus risks,You are twice as likely to catch Covid if you are this height, the search says.
