U.S. scrambling to contain potential measles outbreak

Public health officials in the United States are scrambling to prevent a massive measles outbreak after an infected woman came into contact with thousands of people as she travelled through three U.S. airports; measles is a highly contagious respiratory virus that can be transmitted through coughing or sneezing; the Centers for Disease Control and Prevention (CDC) is in the process of tracking down passengers that may have come into contact with the infected woman and closely monitoring airport employees; each year the disease kills approximately 200,000 people around the world, primarily children, but thanks to widespread vaccinations against measles, fatality rates in the United States are low
