CDC halts infectious disease tests, pharmacists face new pressure
On April 1st, the CDC quietly pulled a growing list of infectious disease tests offline. By April 3rd, 31 tests were suspended, the largest halt in the agency’s history. The official reason? A “temporary pause” for a quality review. No matter the explanation, the reality is clear: the safety net for pharmacists just got weaker.
What’s been suspended
This isn’t just about rare tropical diseases. The list includes two critical rabies tests, poxvirus panels, fungal assays, and a test for Oropouche virus, “sloth fever.” Some tests, like those for Epstein-Barr and varicella zoster, have commercial alternatives. But others, especially for rare diseases, could only be confirmed at the CDC.
The pause on poxvirus testing is especially troubling. Almost four years after the global mpox outbreak, the U.S. still faces new cases. Reliable testing is more important than ever.
Why is this happening?
The CDC calls it routine, but experts and insiders’ question that. Since 2020, CDC labs have lost up to a quarter of their workforce. Some labs, like those for rabies and poxviruses, lost half their staff. The malaria branch suffered even deeper cuts. This is the broadest pause in testing on record, and the loss of experienced staff is hitting hard.
Dr. J. Glenn Morris Jr., a leading infectious disease expert, put it bluntly: “This is a real disaster from a public health standpoint.” For years, the CDC has been the last resort for confirming rare or unexpected infections.
What this means for you
This is where it gets real for pharmacists. You rely on accurate, timely test results to guide patients, give vaccines, and respond to outbreaks. When CDC testing stalls, you’re left with more questions and fewer answers, especially in smaller communities.
Large state labs might manage. Smaller or underfunded ones will struggle. Without CDC support, confirming cases takes longer, investigations slow down, and public health responses may falter. For frontline pharmacists, this means more uncertainty and more responsibility.
What you can do now
Don’t panic, prepare. Here’s how:
- Know your state lab’s capabilities. Contact your state health lab today. Ask which tests they can do in house, don’t assume, confirm.
- Update your triage process. When faced with unusual symptoms or exposures, your first call should now be your state health department, not the CDC.
- Check the CDC’s test directory. The suspended list is changing. Bookmark
cdc.gov/infectious-diseases-labs
and check for updates often.
- Document your process. If you encounter a case needing special testing, record your clinical reasoning, referrals, and what happened. This helps track the impact and supports advocacy for better resources.
Bottom line
This pause may be labeled “temporary,” but there’s no clear timeline. Decades of CDC support can’t be replaced overnight. As pharmacists, we must adapt, stay informed, strengthen connections with state health departments, and be ready to answer tough questions from our communities.
How will this change your approach to patient care? What questions do you have about your local testing options? Let’s keep the conversation going, preparedness starts with knowledge and action.
