Masks Protect Confronting Colds, Influenza
They may wait silly only a new written report finds surgical masks are your best protection against a cold or the influenza.
Donning a face mask — either a surgical mask or a P2/N95 respirator mask (high particulate filter mask) — boosts protection from astringent respiratory illnesses such every bit influenza and SARS, say researchers from the University of New South Wales (UNSW). These masks are not necessarily the same as the dust masks that some people use when cleaning or doing structure work.
In the written report, developed mask wearers in the home were iv times more likely than non-wearers to exist protected against respiratory viruses, including the common cold.
The findings, detailed this week in Emerging Infectious Diseases, the journal of the U.Southward. Centers for Affliction Control and Prevention (CDC), have global implications and are particularly relevant to efforts to combat the spread of flu pandemics and other emerging respiratory diseases such equally SARS.
"In the event of a astringent pandemic, demand for protection could become a constabulary-and-gild issue," said report leader Raina MacIntyre, caput of UNSW's Schoolhouse of Public Health and Community Medicine.
"In a crisis, vaccine development is probable to be delayed and drugs may exist in curt supply or non bachelor at all," MacIntyre said. "Limited supplies volition exist directed beginning to front line health workers, so masks are an of import means of protection for the community, who otherwise may be last in line for vaccines and drugs."
Good news for parents
While some governments are already stockpiling masks for apply in emergencies, MacIntyre said these guidelines had been implemented without evidence to support them.
"Nosotros now accept provided that evidence," she said. "Masks play an of import office in reducing transmission if they are worn properly."
Last year, a CDC study found that wearing face masks and washing hands with booze-bases sanitizer cut down flu symptoms in a community past half.
In May 2007, the CDC issued guidelines saying that surgical masks "should be considered" during a flu pandemic for anyone ill with the flu, entering a oversupply or living with people with flu symptoms. This wording was a watering-down of a previously considered "face up-mask-should-be-worn" recommendation due to a lack of evidence at that time about face masks and the flu.
At a mean solar day-to-day level, the report is also good news for parents of toddlers and young children.
"There is no effective handling for the 90 or then mutual cold viruses that brand families sick each winter, just masks could provide uncomplicated and constructive protection," MacIntyre said.
But you accept to habiliment it ...
Researchers at UNSW, Sydney's Westmead Infirmary, Royal College (London) and the National Center for Immunisation Research studied more 280 adults in 143 families in Sydney during the winter seasons of 2006 and 2007. The adults were randomly allocated masks when exposed to a sick child in the household.
MacIntyre said a drawback was participants' depression compliance, with less than half reporting having worn the masks oftentimes or e'er. However, adherence to preventative measures is known to vary depending on perception of risk and would exist expected to increase during a pandemic.
The adjacent pressing research question is the value of the apply of masks amongst wellness care workers. Preliminary work in Australia in 2007 showed very low acceptance of and compliance with mask use by hospital doctors and nurses.
MacIntyre and her team, along with the Beijing Centers for Disease Control and Prevention, are now running a large trial of masks in close to 2,000 wellness care workers in more than 20 hospitals in China, where compliance with masks is much greater.
"Results from this trial could have broad implications for not only pandemic influenza, but a range of catching diseases spread within hospitals," MacIntyre said.
