On Monday night, parents got the chance to talk with a state health official who studies contagious outbreaks. Epidemiologist Chuck Jennings told the concerned parents that he does not believe the Dongola outbreak is an infectious virus. But, he says his role is to determine that belief to be a fact. To help Jennings do that, school officials are asking every parent in the district to fill out a survey, listing all their children’s symptoms since the end of December. Jennings will compile the surveys and analyze the data, looking for common threads that could help identify the mysterious illness. Jennings also plans to do a blood test on one 6th grader who has been hit hard by the outbreak.
