MMR vaccine

After decades of progress against one of the most contagious human viruses, the world is seeing measles stage a slow, steady comeback.

The World Health Organization and the CDC say in a new report that there were nearly 10 million cases of measles last year, with outbreaks on every continent.

An estimated 140,000 people died from measles in 2018, WHO says, up from an all-time low of 90,000 in 2016.

And so far 2019 has been even worse.

This year saw the largest outbreak of measles in the U.S. since 1994, with 1,250 cases reported as of Oct. 3, largely driven by families choosing not to vaccinate their kids. Worldwide, the disease has resurfaced in areas that had been declared measles-free.

States are debating whether to make it more difficult for students to avoid vaccinations for religious or philosophical reasons amid the worst measles outbreak in decades, but children using such waivers are outnumbered in many states by those who give no excuse for lacking shots. 

In 2000, the Centers for Disease Control and Prevention declared measles "eliminated" from the United States. But with measles continuing to spread and at times flourish in many parts of the globe, the U.S. has been unable to remain immune to the disease.

This year, the U.S. has its highest number of measles cases in 25 years. As of this week, the CDC has recorded 704 cases in 22 states.

The reemergence of measles is linked to parents who have chosen not to vaccinate their children against this highly contagious disease.

Hundreds of students and faculty at two universities in Los Angeles have been asked to stay home unless they can prove that they've been vaccinated against measles.

The LA campuses of the University of California and California State University imposed the quarantine after they became aware of people infected with measles who had potentially exposed hundreds. At UCLA, a student exposed at least 500 people earlier this month; at Cal State, someone with measles went to a library and encountered hundreds.

Washington state has moved a step closer toward making it more difficult for parents to receive exemptions from having their children receive a required immunization.

Columbus Public Health and Jewish Family Services are teaming up to offer free measles vaccinations. 

Measles is surging. Last week the U.S. recorded 90 cases, making this year's outbreak the second largest in more than two decades.

So far this year, the U.S. has confirmed 555 measles cases, the Centers for Disease Control and Prevention announced Monday. That's 50 percent higher than the total number recorded last year, even though we're only about a quarter of the way through 2019.

And the virus isn't slowing down.

New York City on Tuesday ramped up the battle against the spread of a measles outbreak in a Brooklyn hot spot, declaring a public health emergency and calling for mandatory vaccinations.

Mayor Bill de Blasio said the emergency covers four Brooklyn ZIP codes, including most of Williamsburg and Borough Park, which have seen more than 285 cases of the measles since October.

The world has two kinds of measles problems.

In low-income countries like Madagascar and in strife-ridden countries like Yemen, the disease takes a toll because vaccines are not available or accessible or affordable. In Madagascar alone, there have been nearly 80,000 cases and an estimated 900 deaths since September.

A Norwalk teen who got vaccinated against his mother's wishes testified Tuesday before a U.S. Senate committee examining preventable disease outbreaks.  

There's strong new evidence that a common childhood vaccine is safe.

A large study released Monday finds no evidence that the vaccine that protects against measles, mumps and rubella increases the risk of autism. The study of children born in Denmark is one of the largest ever of the MMR vaccine.

All U.S. states require most parents to vaccinate their children against some preventable diseases, including measles, mumps, rubella and whooping cough, to be able to attend school. Such laws often apply to children in private schools and day care facilities as well as public schools.
