BLOOMINGTON, Ill. (Map, News) – Influenza, strep throat and other upper respiratory infections is showing up later than usual in central Illinois.

Dr. Lamont Tyler of OSF St. Joseph PromptCare said this season’s flu vaccine has been more effective than last year’s in battling prevalent strains of influenza. As a result, PromptCare had been averaging one or two verified influenza cases each day.

That has changed recently, with the clinic now averaging seven cases a day. PromptCare is averaging more than 10 cases each day of strep throat, in addition to gastroenteritis and other upper respiratory infections.

Dr. Marlito Favila of HealthPoint in Normal says the clinic is also seeing increased numbers of influenza, pneumonia, sinus infections, bronchitis and ear infections.
