After a New York county declared a state of emergency to prevent the spread of a measles outbreak, why is the once-eliminated disease on the rise again? Measles is an airborne infection causing fever, coughing and rashes that can be deadly in rare cases. It is more contagious than tuberculosis or Ebola, yet is easily preventable with a vaccine that costs pennies. The UN says worldwide cases of measles jumped by more than 30 percent in 2017, and infections continued to rise last year.
Just 10 countries were responsible for the surge in cases in 2018, according to the UN children's agency. While most of the countries that experienced large spikes in cases are beset by unrest or conflict, several wealthier nations also saw their caseloads soar. In all, 98 countries reported more measles cases in 2018 compared with 2017. But the causes varied wildly. The World Health Organization has warned that the growing anti-vaccine movement in richer nations constitutes a top-10 global health threat.
"Anti-vaxxers" have for years cited a fraudulent 1998 study by discredited British researcher Andrew Wakefield that suggested a link between the MMR vaccine against measles, mumps and rubella, and a risk of autism and bowel disease in children. Repeated studies - the most recent involving more than 650,000 children monitored for more than a decade - have shown that there is no such link. The UN children's fund has warned that complacency and misinformation were driving the resurgence of measles among richer nations. "Measles may be the disease, but all too often the real infection is misinformation, mistrust and complacency," UNICEF head Henrietta Fore said this month. Measles cases more than tripled across Europe in 2018, according to the WHO, with notable outbreaks in Romania, Italy and France. The WHO recommends a 95-percent vaccination rate to prevent mass hospitalisations and fatalities. At least 800 children have died from measles since September in Madagascar, where rampant malnutrition and a historically poor vaccine rate are driving the world's worse current outbreak. Yemen also figures on UNICEF's "top 10" list of countries showing the largest increases in measles cases last year with a 316 percent hike, from 2,101 cases in 2017 to 8,742 cases in 2018.
Crisis-hit Venezuela, as well as areas of Brazil, have seen tens of thousands of confirmed measles cases since last year. In the Philippines, where vaccine rates have been declining for years, measles cases jumped from 791 in 2017 to 5,120 last year. Twenty-five people died from measles in January alone.
And in Ukraine, which has experienced five years of simmering conflict with Russia on its eastern border region, more than 30,000 people have caught measles alone this year. At least 11 have died from the illness.
