A 68-year-old Nebraska woman has become the second human in history to discover parasitic cattle worms wriggling around her eyeballs.

The cringy case—which surfaced just two years after the first case in Oregon—raises concern that the worms may be angling for an uprising in the United States.

In a recent report in the journal Clinical Infectious Diseases, parasitologists at the Centers for Disease Control and Prevention noted that the worm—Thelazia gulosa, aka the cattle eye worm—has been in the US since the 1940s. "The reasons for this species only now infecting humans remain obscure," they write. But, "[t]hat a second human infection with T. gulosa has occurred within two years of the first suggest that this may represent an emerging zoonotic disease in the United States."

Ravenous swarms of cloned ticks have killed a fifth cow in North Carolina by exsanguination—that is, by draining it of blood—the state’s Department of Agriculture and Consumer Services warned this week.

Experts fear that the bloodthirsty throngs, which were first noticed in the United States in 2017, will continue their rampage, siphoning life out of animals and eventually transmitting diseases, potentially deadly ones, to humans.

Just last month, infectious disease researchers in New York reported the first case of the tick species biting a human in the US. The finding was “unsurprising” given the tick’s ferocious nature, according to Dr. Bobbi S. Pritt, director of the Clinical Parasitology Laboratory in Mayo Clinic. And it’s “extremely worrisome for several reasons,” she wrote in a commentary for the journal Clinical Infectious Diseases.
