Good Lifestyle

With Covid often transferred from one person to anyone, you may think of your car as a safe place. It's not always. If you have a passenger, "driving around windows up and air conditioning or heat is certainly the worst scenario, according to our computer simulations," says Asimanshu Das, a graduate student at the school of Brown engineering and co-leader of a new studyScientific progress. "The best scenario we found was to have four open windows, but even to have one or two open was much better than having all closed them. »Continue reading to know why, and to ensure your health and health of others, do not miss theseWithout signs that you have already had coronavirus.

The authors performed simulations to find the Drive Safest path

The authors started by performing a simulation. "Transmission of highly infectious respiratory diseases, including SARS-COV-2, is facilitated by transporting exhaled droplets and aerosols that may remain in the air for long periods of time," authors' report. "A tour tourism cabin represents such a situation with a high risk of transmission of pathogens. In their study, they "present the results of numerical simulations to evaluate how the microclimate in a car's cab can potentially spread pathogenic species between the occupants, for a variety of open and closed window configurations. "Their conclusion? "An air flow model that moves through the cab, the furthest away from the occupants can potentially reduce the risk of transmission. Our results show the dynamics of complex fluids during daily movements, and the non-intuitive means in which open windows can increase or remove airborne transmission. "

In other words: keep "the four open windows, but even to have one or two open was much better than having all closed them. »

The CDC and Dr. Fauci warned against the automobile travel

The risk of catching Covid of a driver or a passenger in a poorly ventilated car is why the CDC andDr. Anthony Fauci, High doctor infectious diseases of the nation, warned against travel. "As warm and enjoyable because they are during the holiday season, [try] to keep the gatherings of people in the immediate household," Fauci said. "And if you have other people come, be very careful. It is hoped that they have been tested. You know that very recently, there was negative or they have their own bubble where they are very, very careful in themselves, to protect themselves so that when you get together is much less of a risk [than] anyone One who just gets from an airport or a train station gets in a Uber, but comes to your home, is at the bottom. And then you have a social context. You have no idea who they have been exposed. These are the things you avoid ".

"Consider limiting the number of passengers in the vehicle than those needed (for example, choosing one or two family members who are no longer at risk of serious illness to perform critical races)," says the CDC. "Improve ventilation in the vehicle if possible (for example, open windows or adjust the ventilation / air conditioning in non-return mode). »

As for rideshares, the CDC says the same thing, and also advises: "Do not ride in a vehicle if the driver or other passengers who do not live with you do not wear correctlyFacial masks. So, avoid driving in poorly ventilated cars with other people, and protect your life and the lives of others, and do not visit one of these35 places you are most likely to catch Covid.
