were “unknown agents.” For the sake of objectivity, we based our assumption on the aggregate of information for known pathogens rather than on “expert opinion.” Interestingly, however, the Council of Science and Technology’s “expert opinion” of the percentage of diarrheal illness due to foodborne transmission was 35% (1), nearly identical to the figure we developed. As noted in our article, pat...

To the Editor: As virologists whose specialties include diagnostic electron microscopy (EM), we read with interest the discussion on bioterrorism scenarios (1,2) and the subsequent no...

Optimal Timing of Specimen Collection after Rash Onset for Diagnosis of Measles IgM Antibody
