can wearing a face mask help prevent the spread of flu? we ask the experts

During the flu epidemic in China and Japan, many people wear masks to prevent the spread of infection.
As Australia enters the deadly flu season, can the practice of wearing masks be adopted here?
The United States has entered the flu season ahead of schedule, killing dozens and more than 40,000 people in the laboratory.
Flu cases have been confirmed so far this year.
In Victoria, three young children died of early flu and 23 elderly people in nursing homes.
Nine Old Men
Nursing institutions in new state died of infection.
Another 25 people were killed in Queensland and 17 in South Australia.
The practice of wearing masks began in the early 20th century when the flu outbreak killed 20 to 40 million people.
Masks are now considered part of the country\'s etiquette.
Two years ago, Sayaka Nakamoto, a woman in Altoona, began sewing masks to protect herself and her little daughter from the flu. As Japanese
The born mother began to broaden her design and people began to stop her in the street.
They ask, \"where did you get it ? \"
After getting a lot of feedback, I decided to start selling them, \"mother Altoona --of-
One of them said that she now runs her own online store \"My Little Mo \".
MS Nakamoto has sold dozens of masks since 2017.
Each mask takes about 15 minutes to sew, and they are made of a cotton fiber called \"Japanese double material\" that can be cleaned and reused.
MS Nakamoto said that after Victoria\'s horrible summer flu season, she observed a surge in sales in recent months, confirmed flu cases rose from 2200 this time last year to 10,683 so far this year.
\"Many times people buy them because they want to prevent themselves or their children from getting the flu or spreading bacteria,\" she said . \".
\"I also sold some to cancer patients who are receiving chemotherapy and want to protect themselves.
\"The evidence shows that wearing a mask can help protect others from the disease when the patient is sick.
But the mask is not foolproof.
Professor Stephen Turner said: \"Many surgical masks used by people are not designed correctly and cannot filter out very small particles, so if the flu virus floats around, it may be said by the department head of microbiology at Monash University.
But he added that if a person carrying a virus wears a mask while sneezing in public places, surgical masks can limit the spread of the flu.
In a 2013 study in the United States, the researchers counted the number of virus particles in the air around influenza patients and found that surgical masks significantly reduced the outgoing breath of large virus drops, however, for small viral droplets that can stay in the air for longer periods of time and are therefore more infectious, the effect is poor.
Aeron Hurt, an associate professor at the chief neurologist at the Doherty Institute, said that while masks have the potential to stop the spread of viral particles, the actual nature of wearing masks often means that they are not effective.
Why do people wear masks?
Associate Professor Hurt said that, in general, people wearing masks do this when they are not in good health to prevent others from getting sick.
\"One of the difficulties with surgical masks is that they can be very uncomfortable to wear,\" he said . \".
\"They will soon be saturated with moisture in their breath, and people often start to touch on and around their faces due to their discomfort, which is more than when they don\'t wear masks.
But more is spreading the flu by touching and polluting the surface.
\"There is no shortage of advice on how to prevent influenza, including taking more vitamin C, but Associate Professor Hurt said there is not strong enough scientific evidence to support the effectiveness of these measures.
\"We don\'t have as rigorous research as we usually use to evaluate drugs to tell us if these types of things are effective enough,\" he said . \".
\"Test with something like vitamin C, elder wood, garlic or mother\'s chicken soup. . .
It hasn\'t been evaluated to the level of medicine we expect, so it\'s hard to know if they work.
\"But there is no doubt that good health, good hygiene, regular hand washing, and a healthy lifestyle includes diet, which helps the immune response.
Associate Professor Hurt said that the most effective way to prevent influenza is to vaccinate.
\"The best thing we can do to prevent infection is to get vaccinated,\" he said . \".
\"The way vaccines work is that they produce antibodies, which means that when we are infected with the virus, our bodies will react quickly to the immune response, and we can do it against the virus, hopefully before we start to have any symptoms.
This will actually stop the ongoing transmission.
