-LRB- CNN -RRB- -- State public health officials are contacting airline passengers after a woman with measles traveled through three airports earlier this week , a spokesman for the U.S. Centers for Disease Control and Prevention said Saturday . The woman traveled from an airport in Europe to Dulles International Airport in Virginia to Denver International Airport and , finally , to New Mexico 's Albuquerque International Sunport , said CDC spokesman Tom Skinner . The woman , who traveled Tuesday , was diagnosed with the disease in New Mexico , he said . Health departments in each area , using information from the CDC , are contacting those who may have been exposed to the viral disease . That may include flight crews and airport workers . `` That work is ongoing , '' said Skinner , who could not confirm the airline or airlines and the originating flight 's location . The Colorado Department of Public Health and Environment said people who were working or traveling through Concourse C at the Denver airport after 9 p.m. Tuesday should monitor themselves for any early symptoms of measles , especially fever , from Monday through March 12 . `` People who develop a fever should contact their health care provider or their local or state health department . People with symptoms should not go to child care , school , work or out in public , as they might have the early symptoms of measles and might be contagious , '' the department said in a statement Friday . Typically , health officials concentrate on passengers or crew who were five rows in front of or five rows behind an infected traveler , Skinner said . They are particularly mindful of small infants and children and people with underlying medical conditions . People who had not previously been immunized may have a `` small window '' after being contacted to be vaccinated or given globulins to avoid developing symptoms , Skinner told CNN . In a separate development , measles was confirmed in a 24-year-old woman who took a flight from France and two people in Boston were suspected of having the disease . Boston officials held a free measles vaccination clinic Friday . `` Most of the -LSB- U.S. -RSB- cases are imported into the country , '' Skinner said . Measles is a very contagious viral disease that is easily spread through coughing , sneezing and secretions from the mouth . Measles develops generally seven to 14 days after a person is infected , according to the CDC . A typical case of measles begins with mild to moderate fever , cough , runny nose , red eyes and sore throat . Two or three days after symptoms begin , tiny white spots may appear inside the mouth . Three to five days after the start of symptoms , a red or reddish-brown rash appears . It may spread downward from the face and be accompanied by a temperature spike , the CDC says on its website .
