Battle Against the Aedes Aegypti Mosquito: A Global Effort to Curb Disease Transmission
Intensifying Actions Against Aedes Aegypti in Cuba
At the heart of Santiago de Cuba, in the settlement of Dos Caminos, an intensified campaign against the Aedes aegypti mosquito, a known vector of diseases such as dengue and yellow fever, is underway. The main highway of San Luis is a focal point of these actions, with a significant amount of resources being allocated to combat the mosquito population.
This ongoing campaign mobilizes more than a hundred health workers, including doctors, nurses, lab technicians, and operators. Their primary objective is to eradicate the insect in its primary and advanced stages of life. Simultaneously, they are tasked with consistently raising awareness among the population to prevent the spread of the vector and the diseases it transmits.
Collaborative Effort and Infrastructure Improvement
Despite the progress made, there is a pressing need for greater integration of entities and organizations in the San Luis locality. Communal services must undertake systematic work in terms of solid waste collection and sanitation. Tasks like suppressing leaks and unblocking septic tanks, which fall under the purview of the Aqueduct, need to be addressed urgently.
Efficient management of waste and water systems is critical as these are potential breeding grounds for the mosquito. The report underscores the importance of a comprehensive approach to public health that combines direct intervention, education, and improved infrastructure.
Breeding Mosquitoes to Interrupt Disease Transmission
Parallel to the actions in Cuba, scientists are exploring innovative strategies against disease transmission by the Aedes aegypti mosquito. In Colombia, the World Mosquito Program is breeding mosquitoes to carry the bacteria Wolbachia, known to interrupt the transmission of dengue. This strategy is currently being tested in more than a dozen countries, with the World Health Organization closely monitoring the process.
Releasing Wolbachia-Infected Mosquitoes in Honduras
In an unexpected turn of events, Hondurans are being educated about a potentially more effective way to control the disease by releasing millions of special mosquitoes into the wild. These mosquitoes, bred to carry Wolbachia bacteria, interrupt the transmission of dengue when they reproduce. The offspring, carrying the bacteria, further reduce the possibility of future outbreaks.
In Honduras, where 10,000 people are known to be affected by dengue each year, Doctors Without Borders is partnering with the mosquito program over the next six months to release close to 9 million Wolbachia-carrying mosquitoes.
Sustainable Solutions in the Fight Against Dengue
The Wolbachia strategy, which has been decades in the making, is touted as a long-term sustainable solution in the fight against dengue. The Aedes aegypti mosquitoes are a challenging foe, being most active during the day and thriving in warm, wet environments and in dense cities. Climate change and urbanization are expected to make the fight against dengue even harder, highlighting the need for better tools like Wolbachia.
Experts from the World Health Organization plan to publish a recommendation as early as this month to promote further testing of the Wolbachia strategy in other parts of the world. The strategy’s success, as proven by a 76% drop in reported dengue cases in a large-scale field trial in Indonesia, brings hope for a future with a significantly reduced threat of mosquito-borne diseases.
