The Importance of Face Masks for Travelers: Defending Against Infectious Diseases

As the holiday travel season approaches, the question of whether to wear face masks still lingers. According to Dr. John Brownstein, an epidemiologist, the decision depends on various factors. While masks can effectively reduce the risk of spreading respiratory pathogens, their necessity varies among different groups, with older age groups and those with pre-existing conditions being more vulnerable. Location also plays a role, with crowded or poorly ventilated areas requiring mask usage. Dr. Brownstein emphasizes that masks, along with vaccines, hand washing, and staying home when sick, are essential tools to combat infectious diseases and ensure a healthy holiday season.
