Patient zero of New York’s 2013 measles outbreak finally identified


Patient zero of New York City’s 2013 measles outbreak has finally been found. According to a recent study of the event, a single unvaccinated person would spread the disease.

In 2013, New York experienced its biggest measles outbreak in 20 years, when the disease had disappeared from the country since 2000. A study published on July 30 in the journal JAMA Pediatrics looked at the human and financial consequences as well than at the origin of the contamination.

Patient Zero is a student who in 2013 had returned from London where he was studying to visit his family in the Big Apple. He belongs to the Orthodox Jewish community, in which few people are vaccinated. Quickly, his entourage became contaminated, as did people in other places that he visited.

58 people infected including 45 unvaccinated

The study shows that between March 13 and June 9, no less than 3,351 people came into contact with the virus, 66% of whom had received two doses of the vaccine against the disease. A total of 58 people contracted the measles. Of these, 45 had refused vaccination. In the United States, vaccination is recommended for children by the age of one but it is not compulsory (except to register in some schools). It can be refused for medical or religious reasons.
