    CDCHAN-00447

    The Centers for Disease Control and Prevention (CDC) is issuing this Health Alert Network Health Advisory to notify public health practitioners and clinicians about the urgent need to increase COVID-19 vaccination coverage (i.e., the percentage of the population fully vaccinated) across the United States to prevent surges in new infections that could increase COVID-19 related morbidity and mortality, overwhelm healthcare capacity, and widen existing COVID-19-related health disparities. Increasing vaccination coverage is especially urgent in areas where current coverage is low. Unvaccinated persons account for the majority of new COVID-19 infections, hospitalizations, and deaths. Currently circulating SARS-CoV-2 variants of concern, especially the highly infectious Delta variant (B.1.617.2), are accelerating spread of infection. Unvaccinated and partially vaccinated people need to practice all recommended prevention measures until fully vaccinated. In areas with substantial and high transmission, CDC recommends that fully vaccinated individuals wear a mask in public indoor settings to help prevent the spread of Delta and protect others.
