WHO advises persons to wear mask in public areas
The World Health Organization has changed its advice on wearing face masks and said persons should wear fabric masks when social distancing isn't possible, such as for example on public transportation and in shops.
In line with the WHO, both main routes of transmission of the deadly virus are respiratory droplets and physical contact.
Respiratory droplets are generated when an infected person coughs or sneezes. Anybody who is in close contact (within 1 m) with anyone who has respiratory symptoms (coughing, sneezing) reaches risk of exposure to potentially infective respiratory droplets.
Droplets may also land on surfaces where the virus could remain viable. Thus, the immediate environment of an infected individual can serve as a source of transmission (contact transmission).
Wearing a mask can decrease the potential risk in a sizable extent.
Earlier WHO argued that there is not enough evidence to say that healthy people should wear masks.
Some countries all over the world already recommend or mandate the wearing of face masks in public areas.
WHO on Friday issued a guideline about how to wear masks properly maintaining healthcare. It said appropriate use and disposal of masks are crucial to make certain that they are effective and to avoid any upsurge in transmission.
It suggested inserting the mask carefully, ensuring it covers the mouth and nose. Besides, it ought to be tied securely to reduce any gaps between the face and the mask.
The individual should avoid touching the mask while wearing it. Later, they should remove the mask using the appropriate technique - do not touch leading of the mask but untie it from behind.
After removal or every time a used mask is inadvertently touched, one will have to clean hands using an alcohol-based hand rub or soap and water if hands are visibly dirty.
Damp masks ought to be replaced at the earliest opportunity with a fresh clean, dry mask.
WHO also suggested avoid re-using single-use masks and asked to get rid of them immediately upon removal.
