Wearing a mask is not a practice the Centers for Disease Control and Prevention recommends for preventing infection in healthy travelers.
There is little benefit to wearing a surgical type mask, and may even put you at greater risk for spreading infection, infectious disease doctors told ABC News.
"Many respiratory viruses are spread by large respiratory droplets which are filtered by surgical masks," said Dr. Henry Wu, assistant professor of infectious disease at the Emory University School of Medicine and former medical epidemiologist at the CDC."If someone has a cold or the flu or another viral respiratory infection, wearing a simple mask will decrease the risk of that person spreading infection.
"With N95 respirators, if you wear them properly, the work of breathing is very difficult and should not be worn for a long time," said Dr. William Schaffner, professor of preventive medicine and infectious disease at Vanderbilt School of Medicine and medical director of National Foundation of Medical Diseases."Painter’s masks are very flimsy and aren’t any good for preventing someone from respiratory infection. The CDC is very skeptical for these reasons.
- Wash hands often with soap and water for at least 20 seconds. Use an alcohol-based hand sanitizer if soap and water are not available.
