COVID-19 is mainly spread through droplets that come from your nose and mouth. For example, when you cough, sneeze or talk loudly, it can also be spread by smaller particles (aerosols).
Wearing a face shield that covers your mouth and nose reduces the spread of these droplets and aerosols. There are different types of face shields that help to reduce the transmission of coronavirus. You can also visit http://thehelloface.com/ to explore the best face shields.
The use of a face shield is also recommended in situations in which workers cannot maintain adequate separation from other persons.
Some of the advantages of face shields include:
- The wearer’s face and facial expressions can be seen, which may be important when caring for some residents
- Some types of face shields may be cleaned, disinfected, and reused (depending on the manufacturer’s instructions )
- Provide eye protection that a surgical mask cannot give.
Shields can therefore be very useful tools for those facing very regular contact, at close proximity, with others – for instance in medical settings. They also have great value in professions where nonverbal communication through facial expressions is important, such as teaching. They could be valuable in giving protection and confidence to teachers, enabling them to return to a classroom environment.
For this reason, face shields are procured and highly recommended for key groups such as teachers, health-care workers, emergency services staff, transport workers, and those working in education.
