Table of Contents
Havana, Cuba – December 1, 2023 – Cuba is currently battling outbreaks of dengue and chikungunya, with a recent report indicating a concerning trend in several provinces. While overall fever syndrome surveillance shows a decrease, authorities are warning of increasing cases in specific territories and a generally epidemic-prone situation across much of the country. This report details the current status of these outbreaks, vector control measures, and public health recommendations.
Current Outbreak Situation
As of the week ending november 26, 2023, Cuba reported 5,717 new cases of chikungunya, bringing the total accumulated cases to 38,938. The majority of these cases (37,678) are based on clinical and epidemiological suspicion, while 1,260 have been confirmed thru PCR testing. Dengue fever continues to be present in all 14 provinces, affecting 43 municipalities and 51 health areas. Notably, 14 cases of chikungunya have been reported in individuals under 18 years of age.
Cuba’s diagnostic approach relies on both PCR confirmation and clinical-epidemiological suspicion, notably given the scale of the epidemic. according to Vice Minister Peña García, cases with strong clinical and epidemiological indicators are considered positive even without PCR confirmation, a strategy employed during epidemic situations.https://www.prensa-latina.cu/en/2023/11/27/cuba-reports-increase-in-dengue-and-chikungunya-cases
Vector Control Measures
A key factor in controlling these mosquito-borne diseases is effective vector control. Recent reports indicate an increase in the infestation index to 0.89. The provinces of Camagüey, Pinar del Río, Santiago de Cuba, Sancti spíritus, and Havana are exhibiting the highest infestation levels.
However, there has been significant betterment in adulticidal treatment, increasing from 79% to 90% of planned coverage. Authorities emphasize the need to reach and exceed maximum coverage in these efforts. Adulticidal treatment refers to the spraying of insecticides to kill adult mosquitoes.
Public Health Recommendations
the Vice Minister urged the population, particularly families, to reinforce control and protection measures, focusing on vulnerable groups such as the elderly living alone and children under one year old. These measures include:
* Eliminating Mosquito Breeding Sites: Regularly empty and clean containers that hold water, such as flower pots, tires, and buckets.
* Personal Protection: Use mosquito repellent, wear long sleeves and pants, and use mosquito nets, especially during peak mosquito activity hours.
* Community Involvement: Participate in community-led vector control initiatives.
* early Medical Attention: Seek medical attention promptly if experiencing symptoms of dengue or chikungunya, such as fever, joint pain, headache, and rash.
Understanding Dengue and Chikungunya
Dengue Fever: A mosquito-borne viral infection causing flu-like illness. Symptoms include high fever,severe headache,joint and muscle pain,rash,and sometimes bleeding.severe dengue can be life-threatening. https://www.who.int/news-room/fact-sheets/detail/dengue-fever
Chikungunya: Another mosquito-borne viral infection characterized by fever and severe joint pain. Other symptoms include headache, muscle pain, joint swelling, and rash. While rarely fatal, the joint pain can be debilitating and long-lasting. https://www.cdc.gov/chikungunya/index.html
Key Takeaways
* Cuba is experiencing outbreaks of both dengue and chikungunya.
* The majority of cases are currently classified as clinical-epidemiological suspicions.
* Vector control efforts are being intensified, with improvements in adulticidal treatment.
* Public awareness and community participation are crucial for controlling the spread of these diseases.
* Vulnerable populations, such as the elderly and young children, require special attention.
Looking Ahead
continued monitoring of the situation, sustained vector control efforts, and proactive public health measures will be essential to mitigate the impact of these outbreaks. Authorities are committed to strengthening surveillance, improving diagnostic capabilities, and ensuring access to appropriate medical care for those affected. The success of these efforts will depend on the collective obligation of individuals, communities, and the government.
