Coronavirus & Face masks = not effective!
Dr Jake Dunning, head of emerging infections and zoonoses at Public Health England, said:
Although there is a perception that the wearing of facemasks may be beneficial, there is in fact very little evidence of widespread benefit from their use outside of these clinical settings.
Dr David Carrington, of St George's, University of London told BBC:
…routine surgical masks for the public are not an effective protection against viruses or bacteria carried in the air…
What about Face masks while in Ihram?
Over 2 millions people congregate in Mecca every year to perform Hajj. Pilgrims are exposed to air-borne transmitted disease during this overcrowding period. Several measures have been practiced to reduce the spread of disease particularly the respiratory tract related infection. One of the preventive measures is by using face mask. Nevertheless, the use of face mask among pilgrims is shown to be only partially effective. This is attributed to the knowledge on the air borne transmitted disease, attitude towards wearing, technique of application, and to some extent the design of the face mask itself.
