With 105 confirmed measles cases since October, four more under investigation, and between five and 10 people currently sick, county officials are continuously working to contain the outbreak that has affected families, schools and businesses.

County and state officials administered more than 11,100 measles, mumps and rubella (MMR) vaccines since the beginning of October and recently cracked down on schools that were not following immunization reporting rules set by County Health Commissioner Dr. Patricia Schnabel Ruppert.

ROCKLAND: 9 yeshivas fined $70K over measles vaccination records

MEASLES OUTBREAK: Health officials administered 11,100 MMR vaccines

One school was fined nearly $25,000 and eight others were fined between $5,500 and $7,500 for not reporting student vaccination records. All of the schools were yeshivas in Ramapo.

This outbreak, the biggest in New York in decades, was traced to Israel, where over 2,690 people are affected and multiple deaths have been reported as of late-December. Hospitalizations have also occurred in the county, according to health officials.

There are also 55 measles cases in Brooklyn, seven reported in Orange County and 33 in Ocean County, New Jersey.

Residents are encouraged to check their vaccination records or with a physician to see if they need to get the MMR immunization. Adults need two doses of the vaccine, which is 97 percent effective after the second dose. It is 93 percent effective after a single dose.

Children usually get the first shot between 12 and 15 months and the second shot before starting school. Due to the outbreak, health officials recommend babies get the shot at six months, and then the regular two doses at the scheduled times.

It is possible to get measles even if you are vaccinated, but the case will likely be milder and less contagious, according to health officials.

People are considered immune or protected if:

they have had two doses of the MMR vaccine,

they had a physician or provider confirm measles,

they had a lab test confirming immunity, or

they were born before 1957.

Measles facts

Measles is a highly contagious respiratory virus that is spread by direct contact with nasal or throat secretions of infected people. Symptoms include rash, fever, runny nose, red watery eyes and a cough. People are considered contagious from four days before to four days after the rash appears, and symptoms usually appear 10 to 12 days after exposure, but could appear as early as 7 days or as late as 21 days after exposure.

Measles can stay in a room up to two hours after an infected person visited and can be extremely dangerous, especially for young children, pregnant women and those who are immuno-compromised because of disease. It can lead to pneumonia, brain damage, deafness and death. About one in every four people with measles will be hospitalized.

Anyone with symptoms is asked to stay home, avoid visitors and contact their health care provider or local clinic or emergency room before going in to protect other people.
