Infectious Disease Expert Says CDC Has Been Silent on Hantavirus Outbreak

Marrazzo joined CNN's The Lead with Jake Tapper on May 7, 2026, to discuss the issue. She described the lack of communication from the CDC as notable given the nature of the outbreak. References were also made to a cruise ship in connection with the broader discussion of infectious disease risks.

Hantavirus is a rare but serious respiratory illness transmitted through contact with infected rodents or their droppings.

Hantavirus pulmonary syndrome can lead to severe breathing difficulties and has a significant fatality rate in reported cases. Outbreaks typically occur in areas with high rodent populations, though specific details about the current outbreak's location and scale were not provided in the segment.

Public health officials generally track such cases through state reporting systems. Marrazzo's comments highlight questions about federal communication during infectious disease events. The CDC commonly issues advisories, updates case counts, and provides guidance on prevention when outbreaks are identified.

No specific CDC statement or data on the current situation was detailed in the broadcast.
