LOS ANGELES – A quarantine order was issued on Thursday for hundreds of students and employees at two Los Angeles universities who may have been exposed to measles and either have not been vaccinated or can not check for immunity.
Measles in the United States have climbed to their highest level for the past 25 years, bringing together 700 cases this year as a result of the revival due mainly to disinformation that turns parents into vaccines. Approximately three-quarters of this year's disease was in New York state.
California University of Los Angeles said that Wednesday there were 119 students and 8 lecturers quarantined. Seventy-one students and 127 employees are quarantined at the California State University in Los Angeles after an eventual exposure to measles in a university library.
"The Ministry of Public Health has determined that there is currently no awareness of the current risk associated with measles in the library," said a statement by Cal Sent.
According to Los Angeles, some people can remain quarantined for up to 48 hours before they prove their immunity. Some may have to remain quarantined for up to seven days, officials said.
Such an order obliges exposed people to stay at home and notify the authorities "if they develop symptoms of measles and avoid contact with other people until the end of the quarantine period or while providing evidence of immunity," Health said in a statement.
Orders come as a small epidemic of measles appears in Los Angeles County, including five confirmed cases involving travel abroad. Since Thursday, the state has registered 38 cases of measles; Last year there were 11 at the same time, said Dr. Karen Smith, director of the California Department of Public Health.
The state usually sees less than two dozen cases a year, she said.
This year, California cases cover 11 areas and affect patients from the age of 5 to 55 years.
More than 76% of the patients were not vaccinated or received the recommended two doses of the vaccine, Smith said. Fourteen of those infected have traveled abroad to countries like the Philippines, Thailand, India and Ukraine.
Measles in most people cause fever, runny nose, cough and rash all over the body. However, very few of those infected may suffer from complications such as pneumonia and dangerous swelling of the brain.
Centers for Disease Control and Prevention recommend the vaccine for all over one year, except for people who have had the disease as children. Those who have had measles are immunized.
The vaccine, which became available in the 1960s, is considered safe and highly effective, and so pox was declared to be all but eliminated in the United States in 2000.
