They may take care silly but a new study rule surgical masks are your best protection against a cold or the grippe .
don aface mask — either a surgical mask or a P2 / N95 respirator mask ( eminent particulate matter filter masque ) — boosts protection from severe respiratory unwellness such as grippe and SARS , say researchers from the University of New South Wales ( UNSW ) . These masque are not necessarily the same as the rubble masks that some citizenry expend when cleaning or doing building oeuvre .
Health care worker wearing face mask.
In the study , adult mask wearers in the home were four time more probable than non - wearers to be protected against respiratory computer virus , including thecommon cold .
The findings , detailed this week inEmerging infective Diseases , the diary of the U.S. Centers for Disease Control and Prevention ( CDC ) , have global implications and are specially relevant to efforts to battle the spread of influenza pandemic and other emerging respiratory disease such as SARS .
" In the event of a severepandemic , demand for protection could become a legal philosophy - and - orderliness return , " said field of study leader Raina MacIntyre , read/write head of UNSW ’s School of Public Health and Community Medicine .
" In a crisis , vaccinum development is potential to be delayed and drug may be in scant supply or not available at all , " MacIntyre order . " Limited supply will be directed first to front dividing line wellness workers , so mask are an crucial way of auspices for the community , who otherwise may be last in line for vaccines and drug . "
safe news for parents
While some governments are already stockpile masks for utilisation in pinch , MacIntyre said these guidelines had been carry out without evidence to support them .
" We now have provided that grounds , " she say . " Masks represent an important character in reducing transmittal if they are worn properly . "
Last year , a CDC studyfound that put on face masks and washing handwriting with intoxicant - radix sanitizer abbreviate down flu symptom in a community by one-half .
In May 2007 , the CDC issued guidelines aver that operative masks " should be considered " during a flu pandemic for anyone sick with the flu , enter a crowd or live with people with influenza symptoms . This phrasing was a lachrymation - down of a previously see " aspect - mask - should - be - worn " recommendation due to a lack of grounds at that time about face masquerade party and the flu .
At a day - to - day level , the study is also good tidings for parents of toddlers and young children .
" There is no efficient treatment for the 90 or so mutual cold viruses that make families unhinged each wintertime , but masks could provide bare and effective auspices , " MacIntyre articulate .
But you have to wear it …
Researchers at UNSW , Sydney ’s Westmead Hospital , Imperial College ( London ) and the National Centre for Immunisation Research consider more than 280 adults in 143 family in Sydney during the winter season of 2006 and 2007 . The adult were willy-nilly apportion masks when exposed to a sick child in the household .
MacIntyre said a drawback was participants ' low compliance , with less than half coverage having worn the masks often or always . However , adherence to preventive measurement is live to vary look on perception of endangerment and would be expected to increase during a pandemic .
The next pressing research question is the value of the use of mask among health care workers . Preliminary oeuvre in Australia in 2007 showed very lowly acceptance of and compliance with mask use by hospital doctors and nurse .
MacIntyre and her team , along with the Beijing Centers for Disease Control and Prevention , are now running a big trial run of mask in close to 2,000 health care workers in more than 20 hospitals inChina , where compliancy with mask is much greater .
" outcome from this trial could have wide implications for not onlypandemic grippe , but a range of communicable disease spread within hospitals , " MacIntyre tell .
