Living in the global village created by speedy air travel gives us all kinds of new health worries. Now it’s gotten to the point that just being near an international airport may be enough to put us at risk for malaria.

We still haven’t shaken the memory of Andrew Speaker, the globe-trotting, honeymooner with some nasty tuberculosis or the frequent-flying Mexican national packing a contagious strain of TB with him on numerous trips across the border. Then the Government Accountability Office tells us that the Department of Homeland Security and the Department of Health and Human Services have a lot more work to do to protect us from TB hazards at our borders.

Now our pal Matt Phillips at WSJ’s Middle Seat Terminal blog piles on with some incidental malaria action. In the run-up to a big conference on tropical diseases next month, a Louisiana State University scientist sounds a warning about “airport malaria.” Global warming and stowaway mosquitoes from equatorial climes are leading to malaria cases near international airports in temperate zones within the U.S. and Europe.
