JEFFERSON CITY — The H1N1 flu is still making Missourians ill.
According to the Missouri Department of Health and Senior Services, more than 28,000 Missourians have had some strain of flu this season — 42 times higher than last year.
State health officials are urging parents to make sure children under age 10 have received both the H1N1 shot and the booster shot. School-age children have the highest rate of infection.
