Samoa declared a national emergency last month and mandated that all 200,000 people living on the South Pacific island nation get vaccinated. The government has closed all schools and banned children from public gatherings. In all, 53 people have died in the outbreak since late October, including one adult and two older teenagers. Most of those who have died have been babies and young infants, including 23 children aged less than 1 and 25 children aged between 1 and 4. The government said more than 1,100 people have been admitted to hospitals since the outbreak began and about 180 people remain hospitalized. Among those hospitalized are 19 children who are in critical condition. Samoan authorities believe the virus was first spread by a traveler from New Zealand. New Zealand Prime Minister Jacinda Ardern said Monday that her country was doing everything it could to help curb the epidemic, including sending more than 50 medical professionals and thousands of vaccines to Samoa. Other countries including Britain have also sent teams and supplies. Ardern said the natural curve of infection rates meant that “sometimes things can be worse before they are better.” Figures from the World Health Organization and UNICEF indicate that fewer than 30 percent of Samoan infants were immunized last year. That low rate was exacerbated by a medical mishap that killed two babies who were administered a vaccine that had been incorrectly mixed, causing wider delays and distrust in the vaccination program. The government said about 33,000 people were vaccinated before last month and since then, another 58,000 people have been vaccinated. The World Health Organization has set a target of wiping out measles from most of the world by next year. It says the disease is entirely preventable thanks to a safe vaccine that has been in use since the 1960s, and that measles deaths worldwide decreased by 84 percent between 2000 and 2016 to about 90,000 annually thanks to better immunization.
