This is just from the public health department of the mass:
The Massachusetts Department of Public Health (DPH) confirmed a case of measles diagnosed at Lahey Hospital & Medical Center (LHMC).
The individual was in a contagious period at a number of locations that could have led to exposure to other people. Measles are highly contagious and people who are not immune and have visited the locations on the dates listed below may be at risk of developing measles or may now develop symptoms of the disease. Anyone who has visited these locations on any of these dates during the given times is advised to contact their healthcare provider to confirm their immunization status.
DPH urges anyone who does not know how to vaccinate his measles immunization status with at least one dose of measles Mumps and Rubella (MMR) vaccine. Measles vaccine given within 72 hours of exposure may prevent measles disease and vaccination outside this window provides protection against sequential exposures. Lahey Hospital has contacted people at high risk of exposure and works with DPH and local health authorities to ensure that all exposed people have this information.
Exposures to this person may have occurred at the following locations and times:
Logan Airport Terminal B Boston 8/15, 8:30 am – 10:30 am
Lexington High School Library at 251 Waltham St., Lexington 8/16, 3:30 pm – 5:30 pm
Irving H. Mabee Town Pool Complex 80 Worthen Rd., Lexington 8/19, 24:00 – 2:00.
Lahey Outpatient Center, Lexington 16 Hayden Ave., Lexington 8/20, 11:30 am – 3:00 pm
LHMC, Burlington Emergency Department 8/20, 1:00 pm – 10:30 am
LHMC, Burlington intramural units 7 Central, 6 Central and 5 Central (ICU and CCU) 8/20 from 8 pm to 8 am at 9 am
Those who have been exposed and have started developing symptoms of measles should call their healthcare provider before they go to an office, clinic or emergency room. A visit to a healthcare institution can put others at risk and must be avoided. Anyone who has had measles in the past or who received two doses of the vaccine is unlikely to develop measles, even if they are exposed.
Early symptoms of measles occur 10 days to 2 weeks after exposure and may resemble the common cold (with fever, cough, runny nose and red eyes) and skin rash occurs 2-4 days after the first symptoms have developed. The result usually appears on the head first and then goes down. The result usually lasts a few days and then disappears in the same order.
People with measles can be contagious up to four days before the result appears and the results appear four days after the day.
People who have had measles in the past or who have been vaccinated against measles according to CDC recommendations are considered immune.
"Fortunately, most people are vaccinated against measles", said the state Epidemiologist Dr. Catherine Brown. "Our efforts are now to identify people who may be at risk of becoming ill and being vaccinated, and if they become ill, we ask them to call their suppliers instead of going directly to a healthcare facility."
