The masks do little...
Consider a face mask. Face masks may help but only need to be used when outbreaks become widespread and are declared a pandemic. The most commonly used simple face masks only filter about 62 percent of very small particles, compared to about 98 percent for professional-grade face masks (these are typically designated N-95). Simple face masks are designed to prevent large droplets that are coughed or sneezed from contaminating the environment rather than protecting the wearer. Bring an extra mask along, and kindly offer it to anyone coughing or sneezing who looks sick. This will keep any droplets from landing on you.
If used correctly, masks and -- more likely -- respirators may indeed reduce the risk of getting influenza, according to information released from the CDC. But for people who live in areas with confirmed cases, there is no single action that will provide complete protection. It simply isn't practical to wear a mask all the time, and they are not 100% foolproof.
Face masks and respirators are most useful for people who are in crowded settings, such as classrooms or airplanes, where they will protect the mouth and nose from germs and reduce the likelihood of coughing or sneezing on other people.
Face masks and respirators are sometimes recommended for people who are in close contact with an infected person. "Close contact" is defined as three feet or less by the World Health Organization and six feet or less by the U.S. Occupational Safety and Health Administration.
Face masks and respirators should be worn once, according to the World Health Organization. (Look for face masks labeled for surgical, dental, medical procedure, isolation or laser use.)
Health experts note that face masks and respirators should be used along with other precautions, such as frequent hand-washing, covering coughs, staying at home if ill and avoiding crowds.
Not just high risk people, but people in general really should be taking reasonable caution.
So yeah, even though I was kidding about plastic bubbles, I'm not at all opposed to extra hand washing, staying away from places with a lot of people, and if there was an outbreak here, I wouldn't absolutely discredit wearing a mask. (in my car at least )
