Example 1: A patient presents with diarrhea, vomiting, and abdominal pain after consuming contaminated food. Lab tests identify a small round virus not classified elsewhere, leading to a diagnosis of A08.19., A child experiences severe dehydration and fever due to persistent diarrhea. After ruling out bacterial and parasitic infections, the diagnosis of A08.19 is made., Multiple individuals in a community experience gastroenteritis symptoms. Epidemiological investigation traces the outbreak to a contaminated water source, and affected individuals are diagnosed with A08.19.
