NEW DELHI: Not everybody needs to wear N95 or a surgical mask to protect oneself from Covid-19. Those are best left for health workers and medical professionals. Even a simple homemade mask can work as a protective layer when you step out of home. We show you three simple types you can easily make at home. Follow these instructions.
- Due to increasing evidence that persons with mild or no symptoms can contribute to the spread of COVID-19, face masks and other face covers may be considered a means of source control complementary to other measures already in place to reduce the transmission of COVID-19.
- Evidence is growing that viral shedding of SARS-CoV-2 is higher just before onset of symptoms and for the initial 7–8 days after onset.
- Face masks have been used extensively in the public in Asian countries and have been linked to a slightly lower risk of SARS among persons without known contact with SARS patients during the 2003 SARS epidemic.
- Non-medical face masks and other face covers made of textiles have the advantage that they can be produced easily; they are washable and reusable.
- Medical face masks are currently in short supply. In view of the current pressure to the health systems, their use by healthcare workers needs to be clearly prioritised and protected.
- Wearing a face mask may create a false feeling of security, leading to relaxing of physical distancing and increased frequency of face touching (mask adjustment, etc.)
- Face masks need to be carefully put on and taken off in order to prevent self-contamination.
- Face masks are not well tolerated by certain population groups (e.g. children) or by persons with chronic respiratory disease.
