The coronavirus epidemic shook the people, scarcely any sector not affected by Kovid. In such a situation, to help people, large institutions all over the world are constantly doing research on coronavirus.
A recent study claimed that eating and grocery shopping may be more dangerous than air travel during the Corona epidemic.
But some scientists questioned this, saying that if the criteria for wearing masks and social removal during air travel and in restaurants are properly followed then it will be quite difficult to compare.
Scientists at the Harvard TH Chan School of Public Health in the US say that ventilation systems in airplanes made of high-efficiency particulate air continuously circulate and refresh the air supply that filters more than 99 percent of the Kovid 19 particles.
At the same time, researchers including Professor Arnold Barnett of the Massachusetts Institute of Technology in the US say that HEPA filters may not function effectively in airplanes, as the report suggests.
Speaking to a news agency, Professor Barnett said that HEPA filters are very good. But as suggested by American Airlines are not effective. Filters are not enough, despite these filters having many examples of transmission.
He says that the spread of the infection depends on how the virus reaches the passenger other than breathing, speaking, and coughing or sneezing. Also, no process is fully understood for Kovid-19.
