**Health Alert: Dengue Outbreak in Baja California**
The changing climate, with warmer temperatures, droughts, and floods, is being examined by experts as a contributing factor to the rise in dengue cases. Baja California’s health sector has identified 111 active and unusual cases of dengue.
A woman who became ill in mid-November after traveling to Guadalajara shared her experience: “I had a severe headache, body aches, and joint pain. Initially, I thought it might be COVID, but it turned out to be something else. I felt very unwell.” Another woman from Torreón contracted two dengue serotypes during her trip to Baja California, resulting in intense headaches and lingering joint pain. Fortunately, both women recovered, yet the state has recorded one fatality in San Luis Río Colorado from the virus, heightening concern among travelers.
Ensenada alone reported 23 dengue cases in 2024, some requiring hospitalization but with no fatalities. Across Baja California, of the 357 individuals tested, 111 were diagnosed with dengue, with one death confirmed as of December 3, 2024.
The health sector’s alarm stems from a comparison to 2023, where Ensenada reported only six confirmed cases and Baja California a total of 20. Nationwide, the World Health Organization (WHO) has documented 533,459 dengue cases in Mexico, resulting in 342 deaths by November 2024. This is a significant jump from the 277,963 cases and 203 deaths reported by the end of 2023, marking a 40% increase year-over-year.
Authorities urge vigilance and caution, particularly for those traveling to high-risk areas like Veracruz, Sinaloa, Nayarit, Quintana Roo, Jalisco, Michoacán, Guerrero, Chiapas, Tabasco, and Sonora.
**Understanding and Preventing Dengue**
Sonia Pérez Cabrera, a Public Health expert overseeing epidemiological surveillance in Ensenada, describes dengue as a viral disease with four serotypes, meaning someone can contract it multiple times. Immunity to one serotype does not protect against the others. Dengue does not need antibiotics, but proper medical management is crucial.
The virus spreads through the bite of the Aedes aegypti mosquito, which thrives in clean, stagnant water. Pérez Cabrera emphasizes that this mosquito does not breed in dirty water or streams with organic matter; instead, it seeks clean, still water that has been stagnant for more than three or four days to lay eggs.
The mosquito’s lifecycle is both aquatic and airborne. Once airborne, it can transmit dengue from an infected individual to a healthy one via its bite. Common symptoms include fever, headaches, body and bone pain, and sometimes eye pain.
With the winter vacation season approaching, health professionals worry about travelers neglecting medical care if dengue symptoms appear. “It’s crucial to know if a person has been in contact with someone who traveled to dengue outbreak areas,” said Pérez Cabrera.
Given that dengue has roots as an ancient disease, both the WHO and the Pan American Health Organization (PAHO) view its current rise as a resurgence. One of the most effective control measures is eliminating mosquito breeding grounds, including any small or large stagnant water bodies.
If a household member contracts dengue, everyone should use insect repellent continuously to prevent the mosquito from spreading the virus to others in the home. It’s vital for patients to inform their doctors about any contact with travelers from dengue-prone regions, enabling thorough examination and diagnosis considerations.
Patients with dengue should avoid aspirin, which is contraindicated, and only use appropriate medications like paracetamol under a doctor’s guidance. Incorrect medication use can lead to severe consequences such as bleeding and intense abdominal pain.
Pérez Cabrera stresses the importance of preventive measures to keep mosquito breeding at bay, especially since they can adapt to non-tropical environments once considered safe from them.
In an effort to combat dengue transmission, health institutions promote the “Wash, Cover, Throw, and Turn” campaign, encouraging people to eliminate places where mosquitoes can breed.
**The Economic Burden of Dengue**
The average cost for treating a dengue patient is substantial. WHO estimates suggest that a person typically needs about 12 days at home to recover. Moreover, the World Bank estimates hospitalization costs can exceed a thousand dollars, proving financially burdensome both for the healthcare system and caregivers.
In related news, the emergence of the monkeypox virus has health authorities maintaining heightened vigilance to prevent additional public health concerns. Should a dengue case be confirmed, health services deploy fumigation teams to cover affected communities and nearby areas. The public is urged to allow fumigation inside homes for thorough containment.
**Vaccine Shortages and Regional Health Challenges**
During a recent press briefing, Jarbas Barbosa from the PAHO highlighted the concurrent health threats in the Americas: dengue, oropouche fever, and H5N1 avian influenza. Each disease poses varying risks but collectively represents significant public health concerns.
2024 has seen the largest recorded dengue epidemic since 1980 within the Americas, with over 12.6 million cases and more than 7,700 deaths reported. The majority occurred in Argentina, Brazil, Colombia, and Mexico, with Brazil shouldering most of the cases and fatalities.
Notably, dengue poses a higher risk to young populations. In countries like Costa Rica, Mexico, and Paraguay, children under 15 years old have accounted for a significant portion of cases. Furthermore, in Guatemala, 70% of dengue-related deaths have affected children. Climate conditions, namely droughts, flooding, and rising temperatures, are linked to the increased mosquito breeding that drives these outbreaks.
The PAHO’s strategy addresses improved vector surveillance, patient care management, health worker training, and bolstering community involvement. Dengue vaccines are being implemented in Argentina, Brazil, and Peru, with Honduras planning to follow suit in 2025. However, despite being a valuable community health tool, the current vaccine is insufficient to control outbreaks or deliver immediate relief due to limited availability.
Conversely, the oropouche virus, once primarily confined to the Amazon, is now appearing in new regions. This year alone, 11,600 cases have been reported across 12 countries, mostly in Brazil.
Meanwhile, H5N1 influenza, more commonly found in birds, has recently been diagnosed in cattle in the U.S. and caused infections in humans. In 2024, there have been 58 human cases in the U.S. and one in Canada, eclipsing the three cases reported in the previous two years.

In addition to the pressing concerns regarding dengue, new research indicates that global warming is exacerbating the spread of mosquito-borne diseases. Studies suggest that climate change not only impacts mosquito habitats but also accelerates their life cycles, making the control and management of diseases like dengue increasingly challenging.
Further analysis by climate scientists highlights the need for integrated, cross-border collaborations to develop comprehensive response strategies. These would involve not just medical interventions but also policies addressing climate change and its diverse effects on public health.
As the global community prepares to tackle these threats, ongoing initiatives emphasize local community engagement and education to minimize breeding sites and interrupt transmission. Public health campaigns are critical in shaping behaviors and understanding risk factors associated with the changing environmental landscape.
