Jalisco reporta dos casos sospechosos de viruela símica en Puerto Vallarta

A man from Dallas arrived in Puerto Vallarta on May 27 with what would become Jalisco's first confirmed case of monkeypox. He attended parties at the Mantamar Beach Club over the following week, mingling with other guests, before symptoms emerged on May 30—cough, chills, muscle pain, pustule-like lesions spreading across his face, neck, and torso. When health authorities took samples and instructed him to isolate for three weeks, he refused. He fled back to the United States instead of remaining quarantined, leaving behind a trail of potential exposure that would occupy Jalisco's health officials for weeks.

On June 7, two additional cases emerged as suspicious—meaning the virus was suspected but not yet confirmed. The first was a 40-year-old man from Toronto who had been living in Puerto Vallarta. He had spent time at the same beach club between May 27 and June 4, the exact window when transmission was most likely. By June 7, he developed the telltale signs: a rash that began on the back of his head and spread down his torso and legs, accompanied by itching. The second case involved a 23-year-old woman from Zapopan who had interacted with foreign visitors. Her symptoms started May 31—fever, muscle and joint pain, and a skin eruption similar to the first man's presentation.

Samples from both suspected cases were sent to Mexico's national epidemiological reference laboratory for confirmation, results still pending as authorities moved quickly to contain what could become a larger outbreak. The Secretaría de Salud Jalisco set up an information booth in Puerto Vallarta, fielding questions from anyone who thought they might have been exposed. They visited the beach club and the hotel where the Dallas man had stayed, identifying 23 people who appeared healthy at the time of inspection. But the net was wider than that. By June 8, eighteen people had come to the regional public health laboratory in Puerto Vallarta seeking evaluation, three had visited other health facilities across the state, and thirteen had called in. Epidemiologists were actively monitoring the health status of 37 people total.

Monkeypox spreads through close physical contact with someone showing symptoms. The rash itself is highly infectious, as are the fluids—the liquid, pus, and blood from skin lesions—and the crusts that form as they heal. Contaminated clothing, bedding, towels, and even eating utensils or plates can transmit the virus to others. This meant that anyone who had shared a room, danced close, or eaten from shared plates at the Mantamar Beach Club during those first days of June was potentially at risk.

This was Mexico's second confirmed case of monkeypox. The first had been announced by Dr. Hugo López Gatell, the subsecretario de Prevención y Promoción de Salud, on May 28. Now Jalisco was bracing for more. Health authorities reinforced detection measures across state health units, preparing for the possibility that the virus had already begun spreading beyond what they could see. The man who brought it had made sure of that when he chose to run rather than isolate—a choice that transformed a single case into a public health emergency that would require weeks of contact tracing and vigilance to contain.
