The Bottom Line
- Respiratory viruses—such as influenza, SARS, and COVID-19—can lead to significant illness and death. Globally, COVID-19 has caused over 118 million cases and upwards of 2.6 million deaths.
- Research supports face mask wearing in combination with other infection control strategies such as handwashing and physical distancing.
- Wearing a face mask can decrease the spread of respiratory viruses from one person to another in both health care and non-health care populations.
- Don’t forget to mask up and stay up to date on recommendations and best practices for mask usage by regularly seeking information from government and public health organizations.
