Sancti Spíritus is currently experiencing a five-week streak of increasing rates of suspected dengue cases, particularly impacting Trinidad and the capital municipality. These areas have also seen a rise in Aedes aegypti mosquito breeding sites.
The official newspaper Escambray reported this Thursday, citing Dr. Yurien Negrín Calvo, the Deputy Director of Hygiene and Epidemiology at the Provincial Center for Hygiene, Epidemiology, and Microbiology (CPHEM).
According to Dr. Negrín, while the uptick aligns with seasonal expectations, it has necessitated enhanced epidemiological surveillance across the province.
She noted that no patients have been hospitalized with warning signs in the past week, although she reminded that previously some children have required intensive care.
Warning signs include severe abdominal pain, persistent vomiting, diarrhea, mucosal bleeding, sudden temperature drops, drowsiness, or agitation.
The official advised immediate medical consultation, increased fluid intake, and rest if dengue is suspected.
Rising Health Concerns Beyond Dengue Suspicions
The surge is not confined to suspected dengue cases. Dr. Negrín indicated a growing trend in non-specific febrile syndromes, prompting intensified monitoring in all eight municipalities and health areas, especially those traditionally at higher risk.
Authorities maintain that there is no current dengue transmission in Sancti Spíritus, although they acknowledge "conditions and causes" that could lead to cases.
Preventive Measures and Challenges
In addition, the health system keeps a close watch on international travelers. Mandatory hospital isolation and immediate notification to the Provincial International Health Control Department are required for any signs of infectious disease.
Focal treatment is carried out, especially in high-risk epidemiological blocks. Fumigation efforts target areas with mosquito hotspots, febrile patients, or reactive IgM dengue tests, though these activities depend on "available fuel and pesticide resources in each area," suggesting potential inconsistencies.
Authorities also stress the importance of maintaining clean yards and surroundings, eliminating mosquito breeding grounds, and reinforcing self-monitoring practices.
Historical Context and Regional Vigilance
Last year, Sancti Spíritus faced a challenging epidemiological situation due to arboviruses. In December 2025, local health authorities acknowledged two dengue-related deaths, including a child, amid more than 1,000 suspected cases.
The rise in suspected cases in Sancti Spíritus occurs amidst heightened surveillance for arboviruses in other provinces. For instance, late July saw Guantánamo report 23 suspected dengue cases, with Imías and San Antonio del Sur classified under the highest epidemiological "Alert" level in Cuba's health system.
Similarly, Villa Clara's Ranchuelo municipality experienced a complex situation in July, with simultaneous circulation of serotypes II and IV and 12 hospitalizations, according to official data at the time.
