The Cuban Ministry of Public Health has acknowledged a surge in infectious diseases across the island, attributing this increase to ongoing challenges with water supply and treatment, environmental sanitation issues, waste accumulation, and difficulties in controlling the Aedes aegypti mosquito.
Deputy Minister of Public Health, Carilda Peña García, highlighted the nation's epidemiological struggles during a segment on the "Buenos Días" program, broadcast on Canal Caribe. She confirmed the prevalence of dengue and chikungunya, admitting to a "complicated sanitary situation" in the hardest-hit areas.
Health authorities have previously noted simultaneous rises in arboviral infections, diarrheal diseases, hepatitis, and acute respiratory infections. Specifically, the spread of diarrhea and hepatitis has been linked to shortcomings in environmental sanitation, water treatment, and waste collection.
Challenges in Water Management and Mosquito Control
On Friday, Peña reiterated concerns about water management and environmental issues contributing to mosquito proliferation. The crisis forces many families to store water for extended periods, potentially creating breeding grounds if containers are not properly sealed.
"As long as there is a water source, and conditions inside the home allow it, the mosquito won't move outside," Peña explained. She urged citizens to eliminate potential breeding sites and maintain larvicide treatments in water tanks.
Limited Resources Hamper Mosquito Control Efforts
Efforts to curb mosquito populations face significant obstacles. Peña admitted that fumigation activities are limited due to energy constraints and fuel shortages, as most equipment used requires diesel or gasoline.
In Santiago de Cuba, fuel scarcity has halted fumigation, allowing arboviral transmission to persist alongside high mosquito infestation rates. Meanwhile, Holguín received 50 fumigation units from the Pan American Health Organization to bolster efforts against Aedes aegypti across its 14 municipalities.
Chikungunya's Continued Impact
Chikungunya remains a concern in Cuba, with high incidence rates reported in Pinar del Río, Sancti Spíritus, Villa Clara, and several Havana municipalities. These areas, less affected in the previous epidemic, now host many individuals susceptible to infection following mosquito bites.
Peña noted the chikungunya outbreak last year had widespread effects, leaving many patients with long-lasting joint pain. Key symptoms include persistent fever, joint pain, and inflammation. The Deputy Minister emphasized the heightened risk for pregnant women near term, newborns, young children, and individuals with heart disease or diabetes.
For expectant mothers in high-risk areas, Peña advised potential hospital admission to minimize exposure. She also cautioned against resuming physical activity too soon after recovery, citing cases of young individuals experiencing complications, some fatal, after premature re-engagement in physical exertion.
Concerning Dengue Trends
Regarding dengue, Peña highlighted a seasonal uptick in cases, urging medical consultation for those with fever due to the risk of severe complications. This rise follows a September report indicating dengue incidence was 7.4 times above the expected level for this time of year, with weeks still to go before the typical seasonal peak.
Understanding Cuba's Public Health Challenges
What factors are contributing to the rise in infectious diseases in Cuba?
The increase in infectious diseases is linked to issues with water supply and treatment, poor environmental sanitation, waste accumulation, and difficulties in controlling the Aedes aegypti mosquito.
How is Cuba addressing the chikungunya outbreak?
Efforts include focusing on high-incidence areas, advising vulnerable groups such as pregnant women, and encouraging proper water storage and mosquito control measures.
What challenges are faced in mosquito control in Cuba?
Mosquito control is hindered by energy constraints and fuel shortages, limiting fumigation activities necessary for reducing Aedes aegypti populations.
