Introduction
Measles, a highly contagious respiratory viral disease
characterised by the appearance of fever and a rash,
is the leading cause of vaccine-preventable childhood
mortality worldwide [1]. The incubation time is between
10 and 14 days, and a measles infected person is contagious
from four days before to four days after the rash
appears. Although a safe and cost-effective vaccine has
been available for decades, measles is still an ongoing
public health problem in several European countries.
