According to the Centers for Disease Control (CDC), a total of 217 people have been infected over a two-year period with a strain of Salmonella Typhimurium associated with African dwarf frogs.
According to dvm360:
CDC began tracking the outbreak in April 2009. A single water frog breeder in California was identified in 2010 as the source of African dwarf frogs associated with the human infections.
Local health department staff revisited the breeder in March 2011 to take updated samples, and CDC says Salmonella bacteria was found once again.
Additional testing is being conducted to determine if the Salmonella strain found at the breeding facility is the same strain present in the current outbreak strain.
The states with the most reported cases include Washington, Utah, California, Pennsylvania, Colorado, Virginia and Arizona.
No one has died from an infection, but over 70 percent of patients are under 10 years of age. Symptoms typically last from four to seven days and include fever, abdominal cramps and diarrhea. Among those infected, 34 percent have required hospitalization, primarily due to severe diarrhea.
Per the CDC over 60 percent of those infected had contact with water frogs within a week of becoming ill, and over 80 percent identified the frogs specifically as African dwarf frogs.
