Ohio, Georgia, Minnesota and California are among the 42 states impacted by the Salmonella Typhimurium outbreak that is currently under investigation by CDC, FDA, USDA and state agencies, according to a report in today's New York Times.
CDC has confirmed that a single strain of Salmonella Typhimurium is responsible for 388 cases of salmonellosis, but has not identified which states are affected. That information is coming from the individual states, either directly or via the news media.
Very little information has been released, either by CDC or by the states. Here is what we have learned so far from CDC.
- Number of confirmed cases: 388
- Date of onset of symptoms: September 3, 2008 to December 29, 2008
- Ages of victims: less than 1 to 103 years old
- Number hospitalized: 18% of victims for which that information is available
- Number of deaths: none
Based on the numbers reported in the New York Times article, Georgia (5), Ohio (51), California (51) and Minnesota (30) account for approximately one-third of the confirmed cases. One victim in Georgia was hospitalized, as were at least 12 in Ohio – the only state, as of this evening, to post information about the outbreak on its web site.
The piecemeal way in which CDC released news of this outbreak has led to some inaccuracies in media reports, according to information obtained by the University of Minnesota's Center for Infectious Disease Research & Policy (CIDRAP). Contrary to yesterday's published reports, CDC has NOT activated its emergency response network. CDC spokesperson, Lola Russell, also told CIDRAP News that a report suggesting that chicken was suspected of being the source of the outbreak was incorrect.
CIDRAP reports that 11 of the 30 Minnesota victims were hospitalized and 10 were in nursing homes, according to information it received from the Minnesota Department of Health. One outbreak victim in the state – a woman in her 70's with other health issues – has died. It's unclear, though, to what extent salmonellosis contributed to her death.
CDC is promising an update on this outbreak investigation on January 15th.
