Can face masks help slow spread of coronavirus that causes COVID-19? Yes, face masks combined with other preventive measures, such as frequent hand-washing and social distancing, help slow spread of virus. So why weren't face masks recommended at start of pandemic? At that time, experts didn't know extent to which people with COVID-19 could spread virus before symptoms appear. Nor was it known that some people have but don't have any symptoms. Both groups unknowingly spread virus to others. These discoveries led public health groups to do on face masks. World Health Organization And US Centers For Disease Control And Prevention Now Include Face Masks In Their Recommendations For Slowing Spread Of Virus. CDC Recommends Cloth Face Masks For Public And Not Surgical And N95 Masks Needed By Health Care Providers.
COVID-19 has created another sort of flare-up: worldwide resurgence in single-use plastic and downpour of for most part, unrecyclable personal protective equipment littering city lanes, clogging sewage channels, indeed turning up profound underneath waves. Environmentalists and other campaigners have long worried about rise of current environmental challenge, by adding to bulk plastics as solid waste and correspondingly, microplastics, particularly within aquatic environment. These face masks within littering surface are washed into water bodies through surface flooding and canals, adding to nearness of macroplastics then after microplastics within oceanic medium. Particularly in Africa, this can be rainy season, from May to October, making freshwater and marine environment stack with microplastics. For instance, present author observe face masks of different kinds, colors, and textures in Lake Tana, from Bahir Dar city littering well as in channel in town. Also, in globe, Organization advocacy and research on marine pollution report in February 2020, loads of face masks in ocean in Hong Kong. Also, French environmental NGO that assess and take out different surgical masks amid later plunge to Mediterranean seabed around resort town of Antibes, as shown in Fig. 2 B on June 22 2020. Massive Use Of Face Masks By Emergency Of COVID-19 Gives Evidence Of Environmental Disorder Both In Terrestrial And Aquatic Environments And That Global Pandemic Has Not Reduced Challenge Of Increasing Plastic Pollution In Environment. Massive Use Of Face Masks By Emergency Of COVID-19 Gives Evidence Of Environmental Disorder Both In Terrestrial And Aquatic Environments And That Global Pandemic Has Not Reduced Challenge Of Increasing Plastic Pollution In Environment. Use of polymeric materials has been identified so far as significant source of macroplastics and microplastic particulate pollution in environment. For instance, different packaging plastic materials, bottling plastic materials, and containers from food processing industries are principal sources of microplastic pollution in form of fibers and / or particulate matter in ocean, freshwater and marine environment globally. These polymeric materials will get into bodies in different ways, such as leaching, flooding, and by wind. Similarly, disposable face masks, which make up of polymeric materials, have been getting into environment first as disposal in landfills and dumpsites or littering in public spaces, then after into freshwater, oceans as new emerging source of microplastic fibers. These face masks are degrading / fragmenting into pieces particles with various environmental conditions, commonly less than 5 mm.
Actually, type of respirator, N95 mask offers more protection than surgical masks do because can filter out both large and small particles when wearer inhales. As name indicate, mask is designed to block 95 percentage of very small particles. Some N95 masks have valves that make easier to breathe through. With this type of mask, unfiltered air is released when wearer exhales. Health care providers must be trained and pass fit test to confirm proper seal before using N95 respirator in workplace. Like surgical masks, N95 masks intended to be disposable. However, researchers are testing ways to disinfect N95 masks so can be reuse. Some N95 and even some Cloth masks, have one-way valves that make them easier to breathe through. But because valve releases unfiltered air when wearer breathes out, this type of mask doesn't prevent wearer from spreading virus. For this reason, some places banned them.
