However, masks on an infected person can prevent water droplets with coronavirus from dispersing into the air. This air transmission is the main method through which the coronavirus or other viruses infecting the respiratory tracts are transmitted.<\/p>\n<p>However, <a href=\"https:\/\/time.com\/5799964\/coronavirus-face-mask-asia-us\/\" target=\"_blank\" rel=\"noopener noreferrer\"><em>The Time<\/em> magazine reported from David Hui<\/a>, a respiratory medicine expert at the Chinese University of Hong Kong who studied the 2002 to 2003 outbreak of severe acute respiratory syndrome (SARS) extensively, says it\u2019s \u201ccommon sense\u201d that wearing a mask would protect against infectious diseases like COVID-19 if \u201cyou are standing in front of someone who is sick\u201d.<\/p>\n<p>Also, patients with COVID-19 often have mild symptoms or a complete lack of symptoms but may be contagious to other people unknowingly. Thus masks can be an effective strategy in enclosed areas to prevent the spread of infections to other people.<\/p>\n<h4>CONCLUSION<\/h4>\n<p>Hence, the virus size itself is small enough to penetrate the pores of a fabric mask. Since the virus may get transmitted via aerosols (clusters of the virus in the air droplets) if an infectious person coughs or sneezes, the clusters can be caught in a mask. Thus infected people wearing masks is an effective way to prevent the spread. However, since the infection can be asymptomatic in some individuals, it is better to use masks in enclosed or public places, specifically with older people as they get severely affected by the infection.<\/p>\n<p>Although, thee virus can also be transmitted through eyes as air droplets are the main mode of virus transmission. In case of any symptoms such as dry cough, fever, sore throat and breathing difficulties, it&#8217;s imperative that the individual self isolates and seek medical attention.<\/p>\n<blockquote class=\"twitter-tweet\">\n<p dir=\"ltr\" lang=\"en\">Are there cases of <a href=\"https:\/\/twitter.com\/hashtag\/coronavirus?src=hash&amp;ref_src=twsrc%5Etfw\">#coronavirus<\/a> <a href=\"https:\/\/twitter.com\/hashtag\/COVID?src=hash&amp;ref_src=twsrc%5Etfw\">#COVID<\/a>-19 in your country\/city?
