Cyclospora Outbreak Raises Risks for Some

An immunocompromised American fears for their health under the new administration, citing concerns about infectious disease protection and vaccine technology. The author, who manages multiple sclerosis with B-cell depleting medication, feels vulnerable to pathogens due to perceived setbacks in herd immunity and mRNA vaccine development under Health Secretary Robert F. Kennedy Jr.

Treatment for autoimmune diseases like multiple sclerosis, while improving quality of life, carries significant risks. These include increased susceptibility to infections, where a minor illness for a healthy person could be life-threatening for someone immunocompromised. The author relies on medication like Ocrevus to manage symptoms, acknowledging the trade-offs between treatment benefits and severe health risks.

Compounding these personal health concerns is the recent scaling back of a Centers for Disease Control and Prevention surveillance program. In July 2025, the program that monitored foodborne illnesses was reduced from tracking eight pathogens to just two. Cyclospora, the parasite linked to a current outbreak across more than 40 states, was among those removed from national monitoring.

Research indicates that immunocompromised individuals are significantly more likely to contract cyclospora infections, often suffering chronic or prolonged diarrhea that can lead to malnutrition and dehydration. While healthy individuals typically recover within weeks, the review highlighted that these vulnerable patients require more aggressive treatment. The author points to this reduction in surveillance as a concerning oversight, particularly for those with weakened immune systems.
