‘2019 shaping up to be worst year for measles since ‘90s’, CDC data show

ACCORDING to the Centers for Disease Control and Prevention, 206 measles cases were confirmed in the United States in the first two months of this year, the highest year-to- date number going back more than a quartercentury. The data underscore how anti-vaccine sentiment and the rising incidence of vaccine refusal threaten to bring back a public health threat that had been declared eliminated nearly 20 years ago.

The number of new measles cases in the first two months of this year already surpasses the entire annual totals of all but three years since the disease was declared eliminated in 2000. Many of this year’s cases stem from an outbreak in Washington state, and nearly all of those involve children who weren’t vaccinated against the disease.

The unusually large number of cases early in the year doesn’t necessary portend a record high annual total in 2019. In 2015, for instance, there were 154 cases in the first two months of the year followed by just 34 for the remainder of the year, putting it at right about average relative to the past decade’s annual totals.

In addition to the cases in Washington there are ongoing measles outbreaks in New York, Texas and Illinois, according to the CDC. “These outbreaks are linked to travellers who brought measles back from other countries such as Israel and Ukraine, where large measles outbreaks are occurring,” the agency notes on its website.

In recent years, groups promoting vaccine denial have been able to cultivate large followings on internet platforms such as Facebook and YouTube. Growing public outcry over those companies’ inaction in response to the spread of misinformation led both Facebook and YouTube to announce concrete steps to address the problem in recent weeks.

In late February YouTube announced it was taking steps to prevent anti-vaccine channels from making money off their videos.

This week Facebook announced it would be reducing the visibility of anti-vaccine pages on Facebook and Instagram.
