Authorities in Texas reported 25 new measles cases over the last five days, bringing the state’s total to 223 as the outbreak continues to spread.

Measles is caused by a highly contagious virus that's airborne and spreads easily when an infected person breathes, sneezes or coughs. It is preventable through vaccines, and has been considered eliminated from the U.S. since 2000.

There has been one confirmed measles death while officials in New Mexico determine if a recent death in the state was caused by measles.
