When the Florida Department of Health revised the number of new HIV cases from 6,147 to 4,613—basically erasing one in four cases—it said the changes were a result of routine adjustments. Not everyone believes that explanation.

Creative Loafing Tampa Bay reports that U.S. Representative Kathy Castor wrote a letter to U.S. Health and Human Services (HHS) Secretary Sylvia Burwell, asking officials to look into the statistics.

“A review is particularly important in Florida where the number of public health professionals and county health departments have suffered substantial cuts over the past four years,” Castor’s letter states. “Florida is in a weaker position to address the threat of the Zika virus or other public health emergencies based upon such cuts, so the HIV/AIDS situation may prove to be a cautionary tale. …Gov. Scott and his relevant agencies often need encouragement to provide adequate and necessary care for its most vulnerable citizens.”‎

The earlier reports from the health department showed 6,147 new HIV cases in 2014, which was an increase at a time when most states were seeing decreases. Despite the growing number of cases, the state surgeon general cut staff and spending. After state lawmakers lambasted the move this past January, the health department revised its estimate of new HIV cases from 6,147 to 4,613, basically erasing one in four.

The health department, according to the Tampa Bay Times, claimed that the revised numbers were a result of routine adjustments, such as removing duplicated cases or accounting for instances where a person’s name was spelled differently or a person had actually been diagnosed previously in another state.
