The young adults between ages 15 and 19 who tested positive may have attended a house party on or around July 11 on West Front Street in Middletown, the township's health department said.
Many of the infected teens are refusing to answer questions, NJ.com reports. "Responsiveness has been less than satisfactory," officials told the news outlet.
Anyone who thinks their child may have attended the a party, or participates in sports or any other group activity that may have included anyone potentially exposed, is asked to have them self-quarantine for 14 days to monitor for signs and symptoms.
If they become ill, they should self-isolate and contact your family physician.
