Community mask research

Respiratory viruses, like the coronavirus, spread between humans via direct contact, respiratory droplets and fine-particle aerosols (see figure below). Since the outbreak of the COVID-19 pandemic, demand and prices for personal protective equipment, such as medical face masks, has been up to 100 and 20 times higher than normal, respectively. Shortages of medical masks has contributed to the high rate of infection among healthcare workers. According to new guidelines from several health organization, the use of (homemade) textile face masks is recommended to slow the spread of the COVID-19. Currently, however, guidelines are still limited regarding the textiles to use (for the envelope), and the best suited filter material to be used in these types of masks.
