The face mask was developed by professionals at Shanghai’s Tongji University, and the built-in system allows the wearer know if he or she is exposed to pathogens such as the common flu, H5N1 and H1N1 influenza.
The device sends alert signals wirelessly to cell phones and works best in enclosed spaces with poor ventilation such as elevators.
To test its effectiveness, its creators sprayed virus-laden liquid on it, simulating scenarios with people talking and coughing.
As part of its strategy to fight Covid-19, China maintains the mandatory use of face masks to access any public place and most people keep it even if they walk in the street in the open air.
Since October 10, 2021 and until the end of October, 2022, the government put into effect new adjustments to the sanitary mechanism, also coinciding with the week of holidays for its National Day and the celebration of the 20th Communist Party Congress.
The changes imply that all provinces require the population to present negative results of a RT-PCR test taken 48 hours before boarding any means of public transportation, that is, a bus, train, plane or ferry.
