CDC Pauses Diagnostic Testing for Rabies and Poxviruses: What It Means for Public Health

Public health infrastructure is facing a new challenge as the Centers for Disease Control and Prevention (CDC) has implemented a “pause” on dozens of diagnostic tests. Among the suspended services are tests for rabies, poxviruses, and various parasites. Whereas this federal suspension has raised concerns about potential delays, state health officials—specifically in New Mexico—are working to ensure that essential disease monitoring continues.

The Impact of the CDC Testing Pause

The suspension of these diagnostic tests affects the ability of health departments to quickly identify and confirm specific infectious diseases. According to reports, the pause includes tests for high-stakes pathogens such as rabies and poxviruses. This disruption potentially strains the resources of local and state laboratories that rely on federal support for specialized diagnostics.

In New Mexico, health officials have stated that the state is prepared to handle disease testing despite the federal pause. While they expect day-to-day operations to remain undisrupted, they cautioned that the lack of CDC support could impact the resources available for handling unusual or rare cases ([kanw.org](https://www.kanw.org/new-mexico-news/2026-04-07/new-mexico-health-officials-say-state-prepared-to-handle-disease-testing-amid-cdc-pause)).

Understanding the Risk: Rabies

Since rabies is one of the primary tests affected by the pause, it’s critical to understand the nature of the disease and how to prevent it. Rabies is a preventable viral disease that affects mammals and is most commonly transmitted through the bite of a rabid animal ([NM Health](https://www.nmhealth.org/about/erd/ideb/zdp/rab/)).

Transmission and Common Sources

The vast majority of rabies cases reported to the CDC occur in wild animals, including:

• Raccoons
• Skunks
• Bats
• Foxes

Domestic animals account for less than 10% of reported cases, though cats, dogs, and cattle are the most frequent domestic species reported as rabid ([NM Health](https://www.nmhealth.org/about/erd/ideb/zdp/rab/)). Notably, the United States has been free of dog rabies since 2007 ([CDC](https://www.cdc.gov/rabies/country-data/index.html)).

Symptoms and Progression

The rabies virus attacks the central nervous system, leading to encephalopathy and, if left untreated, death. The disease typically progresses in stages:

• Early Symptoms: Nonspecific signs including fever, headache, and general malaise.
• Neurological Progression: As the disease advances, patients may experience insomnia, anxiety, confusion, hallucinations, agitation, hypersalivation, difficulty swallowing, and hydrophobia (fear of water).
• Outcome: Death usually occurs within days after these symptoms initiate ([NM Health](https://www.nmhealth.org/about/erd/ideb/zdp/rab/)).

Rabies Prevention and Regulations in New Mexico

To mitigate the risk of rabies, New Mexico enforces strict vaccination laws for domestic pets. According to the New Mexico Administrative Code, dogs and cats over three months of age are required to be vaccinated against rabies ([Rabies Aware](https://rabiesaware.org/state/new-mexico)).

Vaccination Requirements

• Initial Booster: Must be administered within 12 months of the first vaccination.
• Subsequent Boosters: Given every one or three years, depending on the specific vaccine’s labeled duration.
• Administration: All rabies vaccines must be administered by or under the direct supervision of a licensed veterinarian ([Rabies Aware](https://rabiesaware.org/state/new-mexico)).

Key Takeaways

• CDC Action: The CDC has paused dozens of diagnostic tests, including those for rabies and poxviruses.
• State Readiness: New Mexico officials believe daily operations will continue, though unusual cases may be more difficult to manage.
• Rabies Danger: Rabies is a fatal but preventable viral disease transmitted mainly via wild animals like bats and raccoons.
• Pet Protection: In New Mexico, rabies vaccinations are mandatory for dogs and cats over three months old.

While the pause in federal testing presents a logistical challenge, the emphasis remains on prevention through animal vaccination and vigilance regarding wildlife interactions. Public health officials continue to monitor the situation to ensure that critical diagnostics remain accessible for those at risk.
