Travelers with confirmed cases of measles passed through five U.S. airports this month and exposed an unknown number of passengers to the disease, ABC News reports, citing city health officials.

Why it matters: The Centers for Disease Control and Prevention says measles, a highly contagious virus that can spread from an infected person through coughing and sneezing, can live for up to two hours in an airspace where the the person coughed or sneezed.

Affected airports and cities

Chicago: An individual with measles traveled through two terminals at O'Hare International Airport over the course of a week. The person passed through O'Hare's Terminal 1 on Dec. 17 and through Terminal 3 on Dec. 12, according to the Chicago Department of Public Health.

Richmond, Virginia: A person with measles visited Richmond International Airport on Dec. 17, according to the Virginia Department of Health.

Austin, Texas: An individual with a diagnosed case of measles visited the United Airlines gate area at Austin-Bergstrom International Airport on Dec. 17, Austin Public Health reports.

Denver and Los Angeles: Three unvaccinated children traveled to a country with an ongoing measles outbreak in early December and tested positive for measles when they returned.

What they're saying: "A small number of [measles] cases are capable of quickly producing epidemics," Dr. Mark Escott, medical director for Austin Public Health, said in a statement.

The big picture: 2019 has been the worst year for measles cases in more than two decades. The CDC has so far confirmed 1,276 cases in most U.S. states.

Italy on Thursday blocked the export of 250,000 AstraZeneca doses to Australia, becoming the first EU country to exercise an export ban due to a vaccine shortfall in the bloc.

Why it matters: The controversial step exposes multiple major challenges to distributing vaccines — even among the world’s richest countries.

Global freedom continues steady decline: report

The global erosion of democracy has continued for a 15th consecutive year, according to an annual report from Freedom House.

Zoom in: The report calls particular attention to India, which slipped from “free” to “partly free” due to the government's “scapegoating of Muslims” and “crackdown on critics.” Prime Minister Narendra Modi is, according to the report, “driving India itself toward authoritarianism.”
