For the first time in a decade, the Venezuelan government has resumed the public dissemination of its epidemiological data, releasing the Boletín Epidemiológico this past Wednesday. The report, which provides a snapshot of the country’s health landscape through the 12th epidemiological week of 2026, reveals a precarious reality characterized by the persistence of preventable diseases and significant mortality rates in rural regions.
As a physician, I view the return of these reports as a critical step toward transparency. Public health relies on the “surveillance-action” loop; without data, the international community and local providers cannot accurately allocate resources or identify emerging outbreaks. The latest figures from the Ministerio del Poder Popular para la Salud indicate that while some diseases remain dormant, others—specifically malaria and yellow fever—continue to claim lives in the country’s interior.
The data highlights a stark geographic divide in health outcomes, with the highest concentrations of infection found in states like Bolívar and Barinas. The report underscores a dangerous trend in lethality, particularly regarding viral hemorrhagic fevers, where the gap between infection and death remains alarmingly narrow.
The Critical Burden of Malaria and Yellow Fever
The most pressing figures in the report concern malaria. In the 12th week of 2026 alone, the national surveillance system recorded 1,128 cases of malaria, with a positivity rate of 7.3%. The burden is overwhelmingly concentrated in the state of Bolívar, which accounts for 81.1% of all cases. Within Bolívar, the municipalities of Sifontes, Atabapo, and Manapiare have emerged as the primary epicenters of transmission.
Looking at the broader timeline, the cumulative total for the first 12 weeks of 2026 reached 25,259 cases, marking an 8.3% increase compared to the same period in 2025. The demographics of the infection are telling: 66.8% of those affected are men, with the most vulnerable age group falling between 10 and 39 years. While a small fraction of cases were imported from neighboring Colombia, Guyana, and Brazil, 98.3% of the infections are autochthonous, meaning they are circulating locally.
Equally concerning is the status of yellow fever. Between 2025 and early 2026, the government confirmed 38 human cases, 21 of whom died. This represents a staggering lethality rate of 55.3%. The virus is most active in Barinas, where 12 cases were recorded, followed by Monagas (5) and Amazonas (4). The report indicates that over 60% of these infections are linked to the “selvático-rural” (jungle-rural) cycle, primarily affecting agricultural workers, laborers, and housewives.
The transmission risk is further validated by “sentinel” events in wildlife. Since 2025, 115 events have been recorded in monkeys across the San Camilo, Sur del Lago, and Guayana corridors. This animal mortality is a classic precursor to human outbreaks, confirming that the virus is actively circulating in the environment, particularly in Aragua, Guárico, and Cojedes.
Hemorrhagic Fevers and Zoonotic Threats
The Boletín Epidemiológico also sheds light on the Venezuelan Hemorrhagic Fever (VHF), a severe disease often transmitted by rodents. The statistics for the past year are grim: in 2025, 32 cases were confirmed with 16 deaths, a 50% fatality rate. The situation has worsened in early 2026, where 3 new cases have resulted in 2 deaths, pushing the lethality rate for the current period to 67%.
Barinas and Portuguesa remain the primary focal points for VHF. To combat this, the Ministry of Health claims to have implemented rodent control measures and encouraged the use of protective gear for agricultural workers, though the high death rate suggests a need for earlier diagnostic intervention.
Beyond hemorrhagic fevers, the report notes a rise in rabies. Four cases of human rabies were recorded between 2025 and 2026 in Zulia and Bolívar. Perhaps more alarming is the 19% increase in suspected rabies-related bites, which rose from 8,965 in 2025 to 10,672 by the 12th week of 2026. The virus is reportedly circulating actively in the metropolitan area of Maracaibo, with domestic dogs serving as the primary reservoir.
| Disease | Cases | Deaths | Primary Focus/Region |
|---|---|---|---|
| Yellow Fever | 38 | 21 | Barinas, Monagas, Amazonas |
| Malaria (W1-12 2026) | 25,259 | Not specified | Bolívar State |
| Hemorrhagic Fever | 35 | 18 | Barinas, Portuguesa |
| Human Rabies | 4 | Not specified | Zulia, Bolívar |
The Silver Lining: Measles and Rubella
Despite the challenges with vector-borne and zoonotic diseases, the report provides one significant piece of positive news: the absence of measles and rubella. The Ministry of Health states that no confirmed cases of either disease have been recorded up to the 12th week of 2026. The last confirmed case in the country dates back to 2019, meaning Venezuela has gone over 365 weeks without a confirmed transmission, although authorities maintain high vigilance due to regional spikes in other parts of the Americas.
What This Means for Public Health
The return of the Boletín Epidemiológico after a decade of silence is more than a bureaucratic update; it is a diagnostic tool for the nation. For the average citizen, these numbers signal a need for increased caution in rural areas—specifically the importance of yellow fever vaccination and the use of bed nets in malaria-endemic zones like Bolívar.
From a medical perspective, the high lethality rates for yellow fever and hemorrhagic fever suggest that patients are likely arriving at health facilities too late or that critical care resources in these states are insufficient. The “focalized vaccination plan” mentioned by the government for high-risk parishes is a necessary step, but its success will depend on the actual availability of doses and the reach of the cold chain in remote areas.

The next critical checkpoint for health observers will be the release of the subsequent monthly bulletin, which will determine if the current focalized vaccination campaigns are successfully curbing the yellow fever cycle in the center of the country. We will continue to monitor these official releases as they develop into available.
