Virulence Factors Associated with Pediatric Shigellosis in Brazilian Amazon

Figure 1

Temporal variation in diarrhea prevalence caused by Shigella and others enteropathogens. From August 2007 to December 2008, 1346 children in the range of 0–10 years old were admitted to hospital with diarrhea and they sought treatment at three hospitals in Manaus, in central of Brazilian Amazon. Stool specimens were collected at which Shigella as much as other enteropathogens were identified by classical methods. Distribution of rainfall over period of study is classified in two levels. Dark gray rectangles were the highest rate of rainfall (between 300 and 600 mm). Light gray indicates the rainfall that was below 200 mm [21].
