• As coronavirus cases rise around the world and in the country, the use of face masks has become mandatory
  • Apart from medical professionals, even flight travellers are being given face shields to ensure their safety
  • Experts are now suggesting that face shields may be a better method of prevention from novel coronavirus infection, as compared to face masks


New Delhi: Initially, when few cases of the coronavirus infection were reported from various places all over the world, the use of face masks for the general public was not recommended. Face masks were to be used by medical professionals, or people who had symptoms of the infection. However, as new information about the virus started to come in, it was found that asymptomatic people may be driving the spread of the virus, and the virus droplets could spread further than the 6 feet distance otherwise set by governments all around the world.

As the viral spread increased in scale, governments all over the world, started to make face masks necessary for one and all, when in a public space. If experts are to be believed, masks may, in fact, stay around for even longer than the virus, even when the pandemic wave is over.

Experts suggest plastic face shields more effective in protecting against coronavirus spread

According to a group of experts, plastic face shields may do a better job at protecting against COVID-19 than cloth, homemade face masks. These face shields are easy to produce and use, and may protect against sneeze and cough droplets from an infected person.

According to Dr Eli Perencevich, Infectious Disease Physician at the University of Lowa, face shields can be quickly and affordably produced. They can significantly reduce the transmission of COVID-19, especially when combined with other practices such as social distancing, quarantine, and contact tracing. Dr Perencevich himself wears a face shield every time he enters a store or a building, he said to the New York Times.

Previously, studies have also shown that face shields can effectively stop the flu virus from entering the body. According to findings of an experiment, face shields may reduce exposure to the virus by 96 per cent, within 18 inches of a cough.

However, recently, the use of face shields has also become popular, and not just among medical professionals who come in close contact with COVID-19 patients. Since domestic air travel was opened up for the general public in India, face shields are being given to passengers by various airlines, in order to ensure their safety.

Many other countries, like Singapore, are also bringing in the use of face shields. When schools reopen, face shields will be provided to the students. In Pennsylvania, face shields have been recommended for teachers after schools reopen.
