Common Questions
What is CIDRAP and who runs it?
CIDRAP is the Center for Infectious Disease Research and Policy at the University of Minnesota, founded in 2001. It is directed by Michael Osterholm and provides independent outbreak analysis.
What did CIDRAP say about the MV Hondius hantavirus cluster?
CIDRAP reported the Andes strain confirmation on 7 May 2026 and director Michael Osterholm assessed the incubation window as pointing to pre-boarding exposure in Ushuaia rather than transmission at sea.Source: CIDRAP
Is CIDRAP independent or funded by pharmaceutical companies?
CIDRAP is funded by the University of Minnesota and philanthropic sources; it does not accept pharmaceutical industry funding, which is cited as the basis for its editorial independence.
How did CIDRAP cover the Idaho dairy H5N1 outbreak?
CIDRAP framed the May 2026 Idaho dairy detections as either renewed spread or persistence in a region where surveillance had previously been quiet, breaking the assumption that the US dairy outbreak had peaked.Source: CIDRAP

Background

CIDRAP (Center for Infectious Disease Research and Policy) is a University of Minnesota research and policy centre founded in 2001 by Michael Osterholm, who serves as its director. CIDRAP provides independent, science-based analysis on infectious disease threats, pandemic preparedness, and biosecurity policy. Its daily news service is one of the few freely accessible English-language news wires focused exclusively on outbreak and pandemic coverage, drawing heavily on peer-reviewed literature and primary institutional sources. CIDRAP is a frequent WHO technical partner and publishes influential reports on topics including the 100 Days Mission, antimicrobial resistance, and influenza pandemic preparedness. It operates without pharmaceutical industry funding, giving its assessments a degree of editorial independence rare among institutions of its kind.

CIDRAP reported the Andes strain confirmation in the MV Hondius cluster on 7 May 2026, establishing that the WHO DON 599 rodent-only risk framing was already outdated at the time of Lowdown's publication. Director Michael Osterholm assessed the HCPS median incubation window as pointing to pre-boarding exposure in the Patagonian port environment rather than at sea, a reading that shapes contact-tracing scope for European authorities. CIDRAP also reported the Idaho dairy H5N1 detections as of May 2026, framing them as either renewed spread or persistence in a previously quiet surveillance region. Its H5N1 coverage contextualised the Emory aerosol study in terms of current CDC PPE guidance gaps.
