2,100 human cases have been reported across the New World screwworm outbreak region — and the United States has now confirmed a domestic return after roughly sixty years.

New World screwworm is back in the United States, and officials have already moved to emergency response

On June 3, 2026, USDA confirmed the first domestic case in roughly sixty years: a three-week-old calf in Zavala County, Texas, with larvae in its navel. Within days, officials confirmed more detections across South and Central Texas and into New Mexico, including cases in a dog and a goat. Then on June 11, the CDC activated a Level 3 emergency response.

The broader outbreak had already been moving north: it reemerged in Chiapas, Mexico, in November 2024 and reached the southern border within eighteen months. The fact pack says more than 185,000 animal cases and 2,100 human cases have been reported across the region during this outbreak.

What’s clear: the pest is now in the U.S., and federal response tools are already in play. What’s not clear from the pack: how far the domestic spread may go.

Gobbles Gobble's Take: When a pest can go from “not here” to “Level 3 emergency” this fast, the calmest sentence in the room is also the most alarming one. Source: FIGHTING SCREWWORM


A grim anniversary reminder: AIDS entered the record in 1981, and the record shaped the crisis

The first official report of what would later be recognized as AIDS appeared in the Centers for Disease Control and Prevention publication Morbidity and Mortality Weekly Report on June 5, 1981. It described five cases of Pneumocystis pneumonia among previously healthy gay men in Los Angeles.

The fact pack’s larger point is blunt: AIDS was never only a biological condition. Its public meaning was quickly entangled with prejudice, and governments, journalists, physicians, religious authorities, artists, and affected communities fought over whose lives were seen as valuable and whose deaths were publicly recognized. Federal officials delayed sustained public engagement, and President Ronald Reagan did not deliver a major public address devoted to AIDS until 1987.

That’s a public-memory warning: how an illness is framed can shape who gets believed, protected, and remembered.
