Cuba Battles Concurrent Dengue and Chikungunya Epidemics, intensifies Public Health Measures

A concerning surge in both dengue and chikungunya cases is gripping Cuba, prompting a nationwide response from public health officials. As of the end of week 46, the island nation is facing a complex epidemiological situation with nearly all provinces designated as being within an “endemic epidemic corridor,” according to a recent report from the Ministry of Public Health.
Escalating Fever Cases and Regional Hotspots
the situation is particularly acute, with a 2.5% increase in fever cases reported in the last week alone. Confirmed cases are currently present in 49 health areas across 41 municipalities within 13 provinces.
Chikungunya is now circulating throughout almost all municipalities, albeit at varying levels of intensity. Authorities have identified Havana,Matanzas,Cienfuegos,and Guantánamo as territories with the highest epidemiological risk due to the simultaneous presence of both arboviruses.
Mosquito Infestation Fuels Outbreak
A senior official emphasized that the primary driver of the current outbreak is the “very high” infestation rate of the Aedes aegypti mosquito. The provinces with the moast significant mosquito populations are Pinar del Río, Sancti Spíritus, Camagüey, Santiago de Cuba, Havana, and Villa Clara. Controlling this vector is now the central focus of the public health response.
Fumigation Efforts and Mandatory Access
Intensive adulticidal treatment – commonly known as fumigation – is underway across the country. The goal is to cover 100% of urban areas within three weeks, however, progress has been uneven. During the last week,only Mayabeque,Havana,Cienfuegos,Ciego de Ávila,and Santiago de Cuba achieved coverage above 95%.
A critical component of the response involves ensuring access for vector control personnel to conduct fumigation. Authorities have stated that refusing access during an epidemic constitutes a crime – specifically, spreading the epidemic – and are urging full cooperation from residents. Following treatment, homes must remain closed for 45 minutes to maximize effectiveness.
Protecting Vulnerable Populations: Children and Pregnant Women
Recognizing the heightened risk to specific groups, the Ministry of Public Health has implemented targeted protocols. Dr. Yamirka Montesino Felipe, head of the National Group of Pediatric Intensive and Emergency Medicine, announced that all children under two years of age presenting with fever should be immediately admitted to hospitals for close monitoring and early treatment. This is particularly crucial for infants under three months and children with pre-existing conditions like oncological diseases, diabetes, epilepsy, or chronic kidney ailments.
“When the child starts to have a fever and the family immediately goes to seek medical assistance, we manage to reach the sick patient early and avoid complications,” a specialist explained. Symptoms in children include persistent fever lasting 48-72 hours, skin lesions, and joint pain. Dehydration, stemming from vomiting and diarrhea, is a significant concern, particularly in infants, underscoring the importance of continued hydration and breastfeeding.
Similarly, pregnant women exhibiting febrile symptoms are to be immediately admitted to hospital institutions. Dr. Diana Couto Núñez,president of the Cuban Society of Gynecology and Obstetrics,stressed that hospital admission allows for prompt symptom control and accurate diagnosis,preventing potentially severe complications. “You cannot make a diagnosis at home. The hospital has to do that,” she stated. Daily morbidity reports from all provinces are being closely monitored to track these cases.
Community Involvement and Reporting Concerns
Public health officials are emphasizing the importance of community participation in eliminating mosquito breeding sites,regularly cleaning water tanks,and allowing fumigation. Residents are encouraged to direct any concerns or complaints to the Vector Control department of their local polyclinic or the Department of Hygiene and Epidemiology of their municipality.
The ongoing battle against dengue and chikungunya in Cuba highlights the critical need for sustained public health vigilance and collaborative efforts to mitigate the spread of these debilitating diseases. .
