Types of face coverings (masks) and coronavirus disease 2019 (COVID-19)
The ongoing pandemic has been increasing slowly and steadily across the world. The SARS-CoV-2 spreads through droplet disseminated from infected persons via coughing and/or sneezing onto the face, nasopharyngeal, and oropharyngeal mucosa. In order to prevent the transmission of coronavirus disease, WHO and public health officials made policies, advised the health workers and public to wear face coverings (masks). The nature of masks depends upon the source, material, structure and particulate efficacies. The main objective of this study is to provide information about efficacies of different types of masks used during COVID-19 pandemic.
