As the number of respiratory syncytial virus (RSV) infections has been rapidly increasing in the New York and New Jersey areas, New York City has recommended wearing masks as a precautionary measure to prevent the spread of the virus. On December 24, the New York City Department of Health advised residents to wear masks when using public transportation, such as subways and buses, or in crowded indoor spaces. The department reported that by December 14, approximately 5,000 cases of RSV infection had been confirmed in the city.
The Department of Health explained that RSV spreads through droplets when an infected person sneezes or coughs. To reduce the risk of transmission, the department emphasized the importance of preventive measures, such as wearing masks and washing hands. Although the mask recommendation is not mandatory, it is part of a broader effort to curb the spread of the virus. The city is also encouraging vaccination for adults over 60, pregnant women, infants, and other vulnerable populations to protect them from RSV infection.
In addition to the RSV surge, New York City had previously issued a flu warning the week before due to a rise in flu cases.
