Public Health Blindness: CDC Alerts Drop Dramatically

Public health officials express grave concern over a sharp decline in health alerts issued by the Centers for Disease Control and Prevention (CDC). In 2025, the agency issued a mere six Health Alert Network (HAN) advisories, a stark contrast to previous years when dozens were common. Experts liken this reduction to "flying blind," arguing that fewer alerts leave doctors, hospitals, and health departments vulnerable and less prepared to handle public health emergencies. These HANs have historically served as crucial early-warning systems for threats like Ebola and the coronavirus pandemic, prompting necessary stocking of supplies and staff preparation.

The current situation is exemplified by the CDC not issuing a HAN for the season's mutated flu strain, nor for the significant measles outbreak in South Carolina, which risks the nation losing its measles elimination status. Critics suggest this "silence" indicates the CDC is being muzzled, pointing to fewer MMWR reports, canceled vaccination campaigns, and paused databases as further evidence of a decline in communication quality and quantity. Former CDC Chief Medical Officer Dr. Debra Houry resigned due to these policies, citing the agency's control by political appointees over scientists.
