Although there are measles outbreaks occurring all over the world at the moment (sigh), Italy's outbreak is of particular concern.
This year, the country has reported 1603 measles cases (through April 16th) according to the Ministero della Salute. To put into perspective how above average that number is - there were 840 cases in all of 2016 and 250 in 2015.
Most cases have occurred in people older than 15 (the median age is 27 for people affected.) It is hypothesized that the effects of people not vaccinating their babies 20 years ago are now coming to light in these adults who are susceptible to measles.
Italy is a hot destination for travelers...
