“Preliminary laboratory studies suggest the outbreak strain of hepatitis A virus is genotype 1B. This strain is rarely seen in the Americas but circulates in the North Africa and Middle East regions.”
As of May 31 when the federal agencies last updated their investigation reports, nine of the 30 sick people had been admitted to hospitals since the beginning of the outbreak on April 29. The five states involved as of May 31 were Colorado, New Mexico, Nevada, Arizona, and California.
The CDC is encouraging anyone who ate the Townsend Organic Anti-Oxidant Blend within the past two weeks to check with their doctors to determine if they should get a hepatitis A vaccine because it can be effective for up to two weeks after exposure.
