"EJIDO PADRE KINO, Mexico — The boy came home from school weakened by fever, his ears burning-hot. Over the next few days, the 7-year-old got sicker — vomiting and complaining of abdominal pain, his mother recalled. Then, the telltale red spots appeared on his hands. But none of the doctors in this rural community along Mexico’s Pacific coast recognized the warning sign for one of the most lethal infectious diseases in the Americas — Rocky Mountain spotted fever. A week later, the boy was dead.
The following year, in 2020, the disease killed a 5-year-old boy in a nearby house. Then last October, a few blocks away, another 7-year-old succumbed to the same scourge.
The disease, spread through the bite of an infected tick that lives primarily on dogs, is rare, but its incidence is rising. It has reemerged at epidemic levels in northern Mexico, where more than 2,000 cases, resulting in hundreds of deaths, have been reported in the past five years. Young children have been hit the hardest. In the Mexican state of Baja California, where Ejido Padre Kino is located, there were 92 cases in 2022, more than double the previous year, according to state data.
The outbreak prompted a team of Mexican and U.S. scientists to descend upon this small town more than four hours south of San Diego to pluck ticks off dogs, scour the crevices around homes for larvae, and warn residents to keep their dogs from roaming the dusty streets."
