The World Health Organization (WHO) issued an update to coronavirus mask-wearing guidance for the first time in nearly six months. In the
update, the health agency advises wearing a mask as part of “a
comprehensive package of prevention and control measures” to limit the
spread of COVID-19.To get more news about

“A mask alone, even when used correctly, is insufficient to provide adequate protection or source control,” the Dec. 1 guidelines said.
“Other infection prevention and control (IPC) measures include hand
hygiene, physical distancing of at least 1 metre, avoidance of touching
one’s face, respiratory etiquette, adequate ventilation in indoor
settings, testing, contact tracing, quarantine and isolation.”The agency
further stated that depending on the type of mask used, it can “be used
either for protection of health persons or to prevent onward
transmission (source control).” WHO recommends that anyone with
suspected or confirmed coronavirus wear the mask while in the presence
of others and that proper use, storage, cleaning and disposal are
essential to effectiveness.
In areas of known or suspected community or cluster SARS-CoV-2 transmission: WHO advises that the general public should wear a
non-medical mask in indoor shared workplaces, schools, or outdoor
settings where physical distancing of at least 1 metre cannot be
maintained,” the guidelines stated. “If indoors, unless ventilation has
been assessed to be adequate, WHO advises that the general public should
wear a non-medical mask, regardless of whether physical distancing of
at least 1 metre can be maintained.”
“Children aged up to 5 years should not wear masks for source control,”
WHO’s guidelines state. “For children between 6 and 11 years of age, a
risk-based approach should be applied to the decision to use a mask;
factors to be considered in the risk-based approach include intensity of
SARS-CoV-2 transmission, child’s capacity to comply with the
appropriate use of masks and availability of appropriate adult
supervision, local social and cultural environment, and specific
settings such as households with elderly relatives, or schools.”
WHO was also careful to note that face shields, at present, are not considered to be equivalent to masks with respect to respiratory droplet
protection or source control. In situations where a mask is not
available or there is difficulty wearing a face mask, it may prove to be
an inferior alternative.
