HARRISBURG (TNS) — A western Pennsylvania county has officially declared it has a measles outbreak.

The Erie County Health Department (ECDH) said in a press release that two additional cases of measles were recently confirmed in Erie County residents.

Both cases were the result of direct exposure to a person who reported positive for the disease on March 30.

Since the three cases are linked, they are defined as an outbreak by the Centers for Disease Control (CDC), the department said.

However, thanks to quarantine measures, the department added that it does not believe there is a high risk of community spread because of these cases.

The department added that anyone who was at the UPMC Hamot-Emergency Department, 201 State St, Erie, between 5:30 and 9 p.m. on April 5 should monitor themselves for any symptoms of measles until April 26.

Anyone who was there at that time and is unvaccinated or doesn’t know their vaccination status should call the ECDH at 814-451-6707.

UPMC said in a statement Tuesday that an unvaccinated child had been diagnosed with measles at the UPMC Hamot earlier this month.

This brings the total number of cases in Erie County up to five. Two previous cases diagnosed in March were the result of international travel.

Measles symptoms usually start with a high fever and cough, which is then followed by red watery eyes, runny nose and a rash that starts at the hairline and spreads over the face and body.

The ECHD said it is working to provide a mobile Measles, Mumps and Rubella (MMR) vaccine clinic.

The CDC reports that as of April 10 there have been 712 cases of measles across 25 states.

Pennsylvania has not seen any deaths, but nine measles cases were reported last week in five counties — Bucks, Erie, Lancaster, Montgomery and Philadelphia.
