CDC Temporarily Halts Testing for Multiple Infectious Diseases Amid Severe Staffing Shortages
The Centers for Disease Control and Prevention (CDC) has announced a temporary suspension of diagnostic testing for more than two dozen infectious diseases, including rabies, human herpesvirus, and several other pathogens. This unprecedented move comes as the federal agency grapples with significant staffing shortages and workforce reductions that have severely impacted its laboratory capabilities.
Testing Services Suspended Across Multiple Disease Categories
The CDC, which normally provides critical testing support to state and local public health laboratories, released a list on Monday detailing the suspended services. Among the affected tests are those for relatively common infections like Epstein-Barr virus and varicella zoster virus (which causes chickenpox and shingles), as well as testing for less common organisms including parasitic worms associated with "snail fever" and the virus responsible for "sloth fever."
In a statement provided to media outlets, a CDC spokesperson explained: "Several infectious disease tests are temporarily paused as CDC evaluates these assays as part of our routine review to uphold our commitment to high quality laboratory testing. CDC maintains regular communication with state and local health departments and can assist in coordinating testing through alternative laboratories if needed."
Staffing Crisis Reaches Critical Levels
The testing suspension follows a period of major workforce reductions at the CDC over the past year, driven by layoffs, retirements, resignations, and the expiration of temporary roles. According to estimates from the Associated Press, total staffing has dropped by 20% to 25%, creating severe gaps in expertise across multiple disease divisions.
By July, the rabies team will reportedly have only one expert capable of providing clinical guidance to state and local officials, while the poxvirus team will have none. The poxvirus and rabies units have each lost roughly half of their staff, while the CDC's malaria division has experienced even more severe cuts, according to the National Public Health Coalition, a group composed of current and former CDC employees formed after the downsizing.
Broader Implications for Public Health Infrastructure
The staffing crisis has broader implications for the nation's public health infrastructure. The CDC was thrown into upheaval last year when more than a thousand employees received notice from the Trump administration that they were losing their jobs in a move that erased entire offices within the agency. Although this decision was partly reversed days later, with hundreds of employees being offered their positions back, the damage to institutional knowledge and capacity had already been done.
In June, the Department of Health and Human Services (HHS) secretary, Robert F Kennedy Jr, controversially hand-picked new members of the advisory committee on immunization practices (ACIP) after firing all the previous members. Those appointments were later stayed after a federal judge ruled that the move probably violated federal law.
As a result, the United States now has no functioning advisory committee on immunization practices, and several key vaccines are no longer recommended, including the latest version of the flu and COVID shots and the inclusion of the RSV shot for infants in the federal Vaccines for Children program, which covers immunizations for more than half of US children.
Looking Ahead: Uncertain Timeline for Restoration
The CDC has indicated that it anticipates some of these tests will become available again through CDC laboratories in the coming weeks. "In the meantime, CDC stands ready to support our state and local partners to access the public health testing they need," the agency's statement noted.
However, the combination of layoffs, hiring freezes, and staff departures has created a significant reduction in the number of experienced scientists available to assist laboratories across the country. This temporary suspension of testing services highlights the fragile state of America's public health infrastructure and raises concerns about the nation's ability to respond effectively to emerging infectious disease threats.
