CORRECTIONVILLE, Iowa (AP) — A Powerball ticket sold in northwest Iowa is worth $1 million. Iowa Lottery officials say the ticket sold in Correctionville, Iowa, matched five of the six winning numbers in Saturday’s drawing. The ticket was sold at a Brew convenience store. The store will receive a $1,000 bonus from the Iowa lottery for selling the winning ticket. No one matched all six numbers to win the jackpot in Saturday’s drawing. So the prize will grow to $90 million for Wednesday’s drawing.

DES MOINES, Iowa (AP) — The Iowa Democratic Party State Central Committee has certified the results of the 2020 presidential caucuses, nearly a month after a faulty mobile app and other problems delayed counting and prompted calls for Iowa to lose its first-in-the-nation status. Iowa awards 41 national delegates in its caucuses. Following Saturday’s certification of the Feb. 3 caucuses, Buttigieg had 14 delegates and Sanders had 12. Elizabeth Warren won eight, Joe Biden won six and Amy Klobuchar won one. The Associated Press opted not to call a winner, given remaining concerns about whether the results as reported by the party were fully accurate.

DUBUQUE, Iowa (AP) — A spike in influenza and other respiratory illnesses in eastern Iowa have led hospitals in Dubuque and Dyersville to limit patient visitation. The Telegraph Herald reports that children under 14 — including siblings of babies in the birth center — are being asked not to visit the hospitals. Those with respiratory or flu symptoms, such as coughing, fever, aches and nausea, are also asked not to visit. Dr. Honorio Caceres is chairman of the bi-hospital infection control committee. He directed that the restrictions be put in place at MercyOne Dubuque Medical Center and UnityPoint Health-Finley Hospital in Dubuque and at MercyOne Dyersville Medical Center.
