Detection of Flesh-Eating Screwworm Parasite in U.S. Traveler Raises Alarms

A flesh-eating parasite is creeping north from Mexico and Central America, spurring the U.S. to launch an aggressive eradication plan. Despite these efforts, a patient recently contracted the country’s first travel-associated case of New World screwworm infestation. On Sunday, August 24, Department of Health and Human Services spokesperson Andrew Nixon told Reuters that health officials confirmed the case on August 4 in a Maryland resident who recently returned from a trip to El Salvador.

‘Warning Fatigue’ Might Have Made Texas Floods Deadlier

A deluge of rain triggered deadly flash floods in Texas Hill Country over the weekend, causing widespread damage and killing more than 80 people. As the death toll climbs, some experts say “flood warning fatigue” may have discouraged residents from heeding the National Weather Service’s (NWS) warnings. Texas Hill Country is part of “flash flood alley,” a crescent-shaped region that curves from the Dallas area down to San Antonio and then westward. It’s one of the most dangerous places in the U.

At least 27 people, including nine children, are dead in central Texas after flash floods struck suddenly on the morning of the Fourth of July holiday. After a storm in which a month’s worth of rain fell in some regions in just a few hours, officials say they rescued more than 850 people from the floods over Friday and Saturday.

Dumping billions of sterilized flies out of planes over Mexico and Texas. Using this tried-and-true biological control technique, the USDA aims to stamp out the larvae of the New World screwworm (NWS) fly, a tropical parasite. This invasive pest’s scientific name is Cochliomyia hominivorax, which literally means “man-
