Quintana Roo Sees 21% Rise in Stomach Illnesses

Quintana Roo, Mexico — The state of Quintana Roo has recorded 1,945 cases of intestinal infectious diseases in the past week, marking a 21 percent increase compared to the previous week’s 1,607 cases, according to data from the National Epidemiological Surveillance System (Sinave).

Rising Cases Linked to High Temperatures and Food Safety Risks

The monitored illnesses include viral diarrhea, salmonellosis, amoebiasis, giardiasis, food poisoning, and other gastrointestinal infections. Health officials attribute the spike to seasonal heat, which creates favorable conditions for the proliferation of viruses, bacteria, and parasites.

Dr. Luis López, a medical expert, explained that high temperatures accelerate food spoilage, particularly when items are improperly stored—a common issue in both households and street food stalls.

“During hot weather, people consume more food outside their homes, often in public spaces or at the beach, without verifying proper hygiene during preparation. There’s also increased consumption of ice or refilled bottled water, which, if not purified correctly, poses a health risk,” López warned.

While most cases present mild symptoms manageable with hydration and rest, López emphasized that persistent fever, vomiting, or severe diarrhea can lead to dangerous dehydration, especially in children, the elderly, and immunocompromised individuals.

Tourist Hotspots Face Heightened Risks

Cities like Cancún, Playa del Carmen, and Tulum are particularly vulnerable due to high tourist traffic, frequent consumption of street food, and inadequate refrigeration of perishable goods. López added that improper handling of drinking water can further facilitate bacterial contamination.

Health authorities urge residents and visitors to take preventive measures, including washing fruits and vegetables, refrigerating food, and avoiding products of questionable origin. They also advise seeking medical attention for persistent symptoms to prevent severe complications.

The current surge aligns with historical trends observed between June and August, when temperatures peak in the region. Officials continue to monitor the situation and reinforce public health advisories.
