Officials confirmed two more human cases of EEE Friday, including a 5-year-old Sudbury girl and a Northborough woman in her 60s — and one state scientist said she expects more cases in coming weeks.

According to Sudbury town officials, the child is in critical condition at an area hospital. All outdoor evening town and school activities in Sudbury were cancelled Friday. Outdoor events for Lincoln-Sudbury Regional High School were also cancelled.

Northborough’s health agent confirmed in a Friday statement that the other new case of EEE was a town resident.
