The Montgomery County Health Department says a resident who visited Nigeria, in Africa, came back with the measles. The 34-year-old woman went to three places while infected. On Sunday, July 24, she was at Victory Christian Fellowship on Audubon Road in Lower Providence. Then from Tuesday night until Wednesday morning she was at the Mercy Suburban Hospital Emergency Department in East Norriton, and later Wednesday she was at Whitemarsh Medical Services in Flourtown. County investigators and staff from local health care facilities are contacting people who might have been exposed and assessing their risk.
