Good Lifestyle

Your hygiene of the diligent hand,mask, social distance and avoid groups and gatherings have become "the new normal" in the prevention of the propagation of COVID-19, as recommended by theCDC. However, according to an expert, there is one aspect of infection that many of us neglect: time.Read on and ensure your health and health of others, do not miss theseWithout signs that you have already had coronavirus.

In a post that became viral during the summer,Risks - Know them - Avoid themErin Bromage, Ph.D., Comparative Immunologist and Professor of Biology at the University of Massachusetts Dartmouth, explain that CIVID-19 infection can be summarized by a simple equation:

"Successful infection = exposure to virus x time."

Simply, the time you spend in a place or an environment where the virus persists can be a huge determinant on the fact that you are sick or not.

In order to protect you, Dr. Bromage encourages you some questions before you venturing into the world, especially as social distancing measures are relaxed. The simple thing is to ask:

How many people will you meet?

How many air flows are there around you?

And

How long will you be in the environment?

Dr. Bromage explains that the virus is extended via air droplets released in the air. Although there is a very small chance that you will be infected by a carrier who simply breathes, your chances increase considerably via a cough, sneezing and even singing, as larger levels of viral particles are released in the air. However, even if you are in a space where a person infected by Covid-19 breathes or speaks, releasing lower levels of viral particles, the more you are exposed to viral particles, your chances of also contacting the increase in the virus.

It also discusses various "super-spreader" events identified by contact tracing (the practice of localization and communication of people who have been in contact or have spent time near an infected person.) They had Place with meat processing plants, large gatherings and events such as weddings, funerals, religious services and restaurants and restaurants. "Any environment that is locked up, with low air circulation and high density of people, problems," he explains.

Once again, the time comes into play.

"The principle is a viral exhibition over a prolonged period of time," says Dr. Bromage. "In all these cases, people have been exposed to the air virus for a prolonged period (hours). Even if they were 50 meters (choir or call center), even a low dose of the virus in the air. , over a prolonged period, was enough to cause infection and in some cases death. "

When you evaluate the risk of infection (via breathing), you shop at the grocery store or in the mall, dine in a restaurant or home of a friend, everything depends on the equation. It explains: "You must consider the volume of airspace (very large), the number of people (restricted), how long people spend in the store (workers - all day; customers - one hour)."

For a person's purchases, this translates into a low density, a high air volume of the store and probably a little time. So, as a customer, your risk of infection is low. However, if you are a store worker, "the prolonged time they spend in the store provide a greater opportunity to receive the infectious dose and that the work becomes more risky."And to cross this pandemic with your healthiest, do not miss these35 places you are most likely to catch Covid.
