Blood test shows if you're immune to measles

Otherwise, very young infants or other vulnerable people can be exposed to the virus. It was caused not by illegal immigration across the Southern border, but by unvaccinated American citizens traveling overseas in Israel - a country that is now having its own measles epidemic. That's the year the federally funded Vaccines for Children program began, which the CDC said led to very stable rates of people vaccinated against the disease. Those who attempt to tie the rise to Southern-border-crossing immigrants do so by ignoring the epidemiological realities of a world that sees one billion people cross worldwide borders every year, sometimes into and out of countries with low vaccination rates or ongoing outbreaks.

The order Tuesday comes as measles has sickened more than 700 people in 22 states this year, including one person in Indiana.

The State of New Jersey Department of Health had confirmed 14 cases of the measles as of April 23.

It said that vaccination rates are plummeting, with inaccurate and misleading anti-vaccination messages on social media thought to be among the reasons.

However, there are some adults who may be in settings that pose a high risk for measles transmission.

The report adds that 40 people in 2019 have brought measles back to the United States after returning from global travel, with Ukraine, Israel and the Philippines being the most frequent sources. If an infected person coughed in a room, 90% of nonvaccinated people in that room would become infected. Most of those cases have been unvaccinated people in Orthodox Jewish communities.

The national rise of measles is a bellwether of a global situation: according to the World Health Organization, measles has seen a 30 percent increase around the world since 2016. It can also cause permanent hearing loss or intellectual disabilities. One in 1,000 will develop swelling of the brain (encephalitis), which can result in permanent brain damage.

What is herd immunity, and are we at risk of losing it?

The recommendations for older adults are more complicated.

But are those who have already been vaccinated safe, or might they need extra protection?

The basic reproductive number of a disease is the average number of people one person can infect in a totally susceptible population. But measles' reproductive number is high, between 12 and 18, meaning that one person, on average, infects 12 to 18 other people. McCormick commented on her actual real-life measles experience, telling CNN that it spread through her family and was "not a fun thing". Above that threshold, the virus just keeps hitting walls of immunity, and can't spread. The disease has no opportunity to gain a foothold.

The current outbreak has been concentrated in New York City, where officials said more than 390 cases have been recorded since October, mostly among children in Orthodox Jewish communities in Brooklyn. What's the difference between eliminating and eradicating a disease? Outbreaks can still happen but are triggered by travel to countries where the disease is not eliminated.

Where are the biggest outbreaks, domestically and globally?

This New York measles outbreak, comprising 423 of the 704 individual infections, represents the vast majority of cases that are part of this troubling resurgence of measles in 2019.
