Pathogens and Outbreaks

Methyl Iodide Fumigation of Bacillus anthracis Spores

Fumigation techniques such as chlorine dioxide, vaporous hydrogen peroxide, and paraformaldehyde previously used to decontaminate items, rooms, and buildings following contamination with Bacillus anthracis spores are often incompatible with materials (e.g., porous surfaces, organics, and metals), causing damage or residue. Alternative fumigation with methyl bromide is subject to U.S. and international restrictions due to its ozone-depleting properties.

Is it in the Water? Investigation of a Waterborne Norovirus Outbreak

Norovirus outbreaks are becoming common and environmental health professionals are trained and experienced in environmental controls, such as proper cleaning procedures, to halt outbreaks. But what happens when the environmental controls are not preventing the spread? What other methods of transmission should you consider? Learn in this session how one county investigated and halted a Norovirus outbreak that resulted from contaminated well water.
