The family Orthomyxoviridae, which includes the Influenza A, B, and C viruses, is distinguished by a segmented, negative-strand RNA genome. While the Influenza C virus genome only includes 7, the Influenza A and B virus strains each have 8 distinct RNA segments. Classic Influenza symptoms in people have been linked to infections by strains of all 3 Influenza kinds (genera).
