Direct evidence to support the use of face masks in the community is “very limited” but an increasing amount of indirect evidence suggests they may be beneficial, according to the State’s health watchdog.
“Data on the potential undesirable effects of face masks usage is also limited, however consideration of the potential harms associated with their use must be balanced against the harms associated with Covid-19,” the Health Information and Quality Authority said.
Face masks should be used to protect against Covid-19 when physical distancing is not possible, Hiqa has recommended in newly-published advice to Government.
Irish recommendations are “largely in line” with other countries, it said, though some countries have recommended face-mask use outdoors.
“The evidence points towards face-mask use in the community reducing transmission of SARS-CoV-2,” said Dr Máirín Ryan, Hiqa’s deputy chief executive and director of health technology assessment.
“There is no consistent evidence that face-mask use leads to a false sense of security or reduced adherence to other public health measures. There are, however, reports of discomfort and skin irritation related to face-mask use,” she said.
Hiqa’s recommendations were submitted last month, leading the Government to recommend from November 27th that face masks should be worn in crowded workplaces, places of worship and busy crowded outdoor spaces.
