South Dakota had its first confirmed case of influenza in October, a month earlier than expected by medical experts. State epidemiologist Lon Kightlinger says the first cases typically crop up closer to Thanksgiving and peak in February and March. The most recent South Dakota Department of Health report has 68 cases of influenza confirmed across the state. Kightlinger talks about the early cases, whooping cough and this summer's spike in West Nile on today's Dakota Midday.
