"Surgical masks as good as respirators for flu and respiratory virus protection

"“Yes, a surgical mask can help prevent the flu,” Sherif Mossad, MD, an infectious disease specialist at the Cleveland Clinic, tells Health. “Flu is carried in air droplets, so a mask would mechanically prevent the flu virus from reaching other people.” It would work both ways, says Dr. Mossad, preventing transmission of the flu virus to others and for keeping a mask-wearer from picking up an infection.
Surgical masks to prevent the flu can be found in major drugstores and online, and yours doesn't need to be fancy to help. “A simple disposable mask is fine, just be sure the packaging notes that it protects against airborne particles,” Susan Besser, MD, a family medicine doctor with Mercy Personal Physicians at Overlea in Baltimore, Maryland tells Health. And splurge for a value-sized pack. “Disposable is best and you should discard your mask after each use,” says Dr. Besser. “If a mask gets wet—and it will by simply breathing into it—the effectiveness of its protective effect is reduced.”"

"One study shows that when there's a sick family member in the house, other family members could cut their risk of getting sick by 60% to 80% by using face masks consistently and correctly -- in combination with frequent hand washing and avoiding close contact with the sick person."

"Donning a face mask — either a surgical mask or a P2/N95 respirator mask (high particulate filter mask) — boosts protection from severe respiratory illnesses such as 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 construction work.
In the study, adult mask wearers in the home were four times more likely than non-wearers to be protected against respiratory viruses, including the common cold."

"Not so for the World Health Organization or the Society for Healthcare Epidemiology of America, the Infectious Diseases Society of America, the Association for Professionals in Infection Control and Epidemiology, and the American College of Occupational and Environmental Medicine.
They collectively recommended regular surgical masks except in high risk circumstances, such as during open suctioning of airway secretions and other procedures that could "aerosolize" the H1N1 virus."

"According to a study published in the International Journal of Infectious Diseases, families with kids who had flu-like symptoms and used the masks properly were 80% less likely to be diagnosed with the same thing.
Another study looked at 400 people who had the flu found that family members who wore a surgical mask and washed their hands reduced their chance of getting the flu by 70%.
“Individual brands of masks and that sort of thing hasn't been studied, but the few studies that have looked at them do have an effect – in some studies, up to 50 to 80% reduction in transmission,” UW virology expert Alex Greninger said. “They seem to stop large droplets, and I think the other key thing to mention with masks is that it really depends on what you're willing to wear.”
Coronavirus is most commonly spread through the air by coughing or sneezing or though close personal contact, such as touching or shaking hands, according to the Washington State Department of Health.
While masks do seem promising, it's also important to utilize other preventive measures. Make sure you wash your hands often during flu season, especially if you're around others who may be sick. Also, be sure to get your annual flu shot to protect yourself and others from spreading the virus."

"At the start of flu season in the last two years, participants were randomly assigned to six weeks of wearing a standard medical procedure mask alone, mask use and hand sanitizer use, or a control group with no intervention. Researchers followed students for incidence of influenza like illness symptoms, defined as cough with at least one other characteristic symptom such as fever, chills or body aches, Monto said.
From the third week on, both the mask only and mask/hand sanitizer interventions showed a significant or nearly significant reduction in the rate of influenza-like illness symptoms in comparison to the control group. The observed reduction in rate of flu-like symptoms remained even after adjusting for gender, race/ethnicity, hand washing practices, sleep quality, and flu vaccination."

I think wearing a mask if it did nothing else would remind me not to touch my face.
