A sharp increase in syphilis cases has led the Alabama Department of Public Health to issue a health advisory for north Alabama.
The ADPH says there's been a 90 percent increase in reported cases over 2015 in Madison County. The department announced Friday that 54 cases have been reported in Madison County in 2016.
Health officials say infection can occur after a person has direct contact with a syphilis sore during sex. Syphilis can also be passed from a pregnant woman to her baby.
