In Healthbeat, Dr. Jay Varma warns that recent U.S. federal funding cuts to CDC and state public health laboratories will cripple the nation’s ability to detect, monitor, and respond to infectious diseases, environmental hazards, and newborn conditions. Public health labs are often invisible to the public, but they provide essential services that commercial and academic labs cannot — from testing for rabies and botulism to sequencing new viral variants and screening every newborn for treatable genetic disorders. Without adequate funding, the U.S. risks slower outbreak response, delayed diagnoses, and increased preventable illness and death
The Overlooked Backbone of Public Health
When most Americans think of public health, they picture vaccines, press conferences, or health inspectors. Few realize that public health laboratories form the foundation of disease detection and safety — confirming rare diagnoses, responding to outbreaks, and conducting surveillance for infectious and non-infectious threats.
Every state maintains at least one public health lab, staffed by highly trained specialists in microbiology, molecular biology, and chemistry. A handful of large cities, including New York City, run their own. These labs fill a market failure: performing tests too rare, complex, or unprofitable for commercial or academic facilities.
“Cutting public health labs may seem cost-saving now, but it’s likely to prove more expensive over time when considering preventable illnesses, delayed outbreak response, and lives lost.” —Dr. Jay Varma
Critical Functions of Public Health Labs
Confirming rare and dangerous diseases
- Rabies: Only public health labs routinely test animal heads and carcasses after human bites.
- Botulism: Confirmed by injecting patient samples into mice to detect lethal toxin.
- Emerging pathogens: Public health labs in the Laboratory Response Network validate and deploy new tests before private labs can.
Supporting outbreak response
- Foodborne illness (Salmonella, hepatitis A) and large-scale exposures require surge testing capacity.
- Seasonal surveillance: Labs test for influenza, RSV, and other respiratory viruses, even when patients don’t need tests for clinical care.
- Subtyping pathogens: From sequencing new Covid-19 variants to testing for H5N1 flu strains, these labs provide vital data.
Guarding against non-infectious threats
- Environmental testing of water, soil, and consumer products for contaminants.
- Universal newborn screening: Detecting conditions like cystic fibrosis and hypothyroidism before symptoms cause permanent harm.
Why Commercial and Academic Labs Can’t Replace Them
Commercial labs are profit-driven and unlikely to invest in rare or unprofitable tests. Academic labs often lack the infrastructure for high-volume, 24/7 operations or the legal clearances for bioterrorism investigations. Public health labs alone combine technical skill, regulatory authority, and national security partnership.
Consequences of Funding Cuts
In early 2025, HHS eliminated two CDC specialty labs and rolled back state laboratory funding. These changes threaten:
- Delayed outbreak detection: Slower recognition of emerging infections.
- Longer turnaround times: Delays in life-saving results, from rabies tests to newborn screens.
- Fewer personnel in crises: Weaker surge capacity when emergencies strike.
- Reduced data: Less surveillance for communities to understand health risks.
During Covid-19, public health labs already struggled with surging demand and shifting federal guidance. Cutting their resources now will leave the U.S. less prepared and, ultimately, facing higher costs from preventable illness and death.
Public health labs may be invisible, but their absence will be painfully obvious. Funding cuts risk undermining the very infrastructure that has quietly protected Americans for decades. As Varma emphasizes, saving money today will cost lives tomorrow.
