Avian Flu- Assessing Environmental Health Issues

Pose THREE indepth questions or requests for clarification to the following statement: A connection between avian influenza infection and food sources was made in Thailand when 147 of 418 tigers fed raw chicken carcasses contacted H5N1 avian influenza and suffered pneumonia. This suggests that ingestion of raw infected birds could be a route of exposure in mammals (Weir, 2005). The live virus has been found in imported duck, although is not thought to be a public health risk if proper cooking methods are used (World Health Organization, Avian Influenza, 2005). Avian influenza is currently a health risk for animals and humans who come in contact with feces or respiratory secretions of infe... click for more

Waterborne Diseases - Public Health Risk

Pose 3 informed questions to the writer of the following comment: Since the latest disasters Tsunami and Katrina the concern for waterborne diseases seems to be a concern for not only the public, but a national public health concern. The CDC reported that since 1971, the CDC and the U.S. Environmental Protection Agency have jointing decided to hold a surveillance program where periodic reporting and data collection of outbreaks is carried out.
