Here’s a breakdown of the provided text, focusing on the key information about dengue and the Wolbachia method in Goiás:
Dengue Situation in Goiás:
Current Statistics (as of an unspecified date, but before the second semester implementation):
Notified cases: 123,232
Confirmed cases: 72,382
Confirmed deaths: 53
Under investigation: 79
Comparison to previous Year (2025 vs. previous year): A reduction of 69% in dengue cases. Ongoing Need for Care: Despite the reduction, continued vigilance against the mosquito and its breeding sites is crucial.
Wolbachia Method Implementation in Goiás:
Scope: Goiás will participate in the implementation, along with two other unspecified municipalities and the capital, Brasília. Timing: Predicted for the second semester, with the exact date to be set.
What it is:
A complementary strategy to combat arboviruses (dengue, zika, chikungunya).
Involves releasing Aedes aegypti mosquitoes that have been infected with the Wolbachia bacteria.
These mosquitoes are called “wolbitos.”
how it effectively works:
The Wolbachia bacteria prevents the advancement of arboviruses within the mosquito’s body.
This reduces the transmission of these diseases.
When mosquitoes with Wolbachia reproduce with local mosquitoes,they pass the bacteria to their offspring.
Over time, most mosquitoes in the region will have Wolbachia, substantially reducing virus transmission and providing continuous protection.
Safety and Nature:
The method is safe and natural.
It does not involve genetic modification.
It is self-sustainable.
It poses no risk to the population or the surroundings.
Wolbachia bacteria is naturally present in about 60% of insects globally.
Scientific Support and Endorsements:
Supported by national and international scientific studies.
Successfully implemented in various cities worldwide with notable reductions in arbovirus cases.
recommended by the World Health Institution (WHO).
Part of Brazil’s public health policies.
Conducted by Fiocruz in partnership with the Ministry of health. operationalized by Wolito do Brasil.
Preliminary Results (Example from Niterói, Rio de Janeiro): Preliminary data indicates a reduction of up to 70% in dengue cases.
Timeframe for Assessing Impact: The average time to assess the impact on the number of cases through scientific and epidemiological studies is typically two years after implementation.Key Recommendations for the Public:
Continue Traditional Care: Maintain traditional measures to eliminate Aedes aegypti and its breeding sites.
Collaborate with Agents: Cooperate with initiative agents.
No Difference in Local Mosquitoes: There is no noticeable difference between the local mosquitoes and those with Wolbachia in terms of their need for elimination.
Origin of the Method:
The first Aedes aegypti mosquitoes with Wolbachia were released in Cairns, Australia, in 2011.
Researcher Luciano Moreira brought the method to Brazil.
In essence, the text highlights a significant reduction in dengue cases in Goiás compared to the previous year, but emphasizes the ongoing need for public vigilance. It then introduces the Wolbachia method as a scientifically supported, safe, and complementary strategy that will be implemented in Goiás and Brasília to further combat arboviruses by reducing disease transmission through modified mosquitoes.
