The two maps published this Saturday (4) began to be used as strategic tools in the fight against chikungunya in Dourados, 230 kilometers from Campo Grande.The cartographic presentations enable both the daily development of the cases and the monitoring of the accumulated panorama of the disease since the beginning of the year and provide technical support for more precise decisions of the health teams.

Two strategic maps have been released to fight chikungunya in the city of Dorados, 230 km from Campo Grande.Developed in partnership between UFMS and City Hall, they allow daily case tracking and have been stored since January.As of April 2, 2,812 notifications have been registered, 1,198 have been confirmed and five people have died, all of them indigenous.The federal government allocated 3.1 million dollars and mobilized 40 experts from the SUS national force to provide 1,288 services.
From reading the material it appears that the spatial surveillance plays a central role in understanding the dynamics of the disease in the municipality.One of the maps shows the distribution of reported and confirmed cases over time, with daily updates.The analysis specifically focuses on records from the last seven days since the onset of symptoms, allowing for the identification of active transmission areas with greater precision.

The second map expands the time frame and combines data from January to provide a comprehensive picture of Chikungunya's progress.This data overlay helps distinguish between areas with persistent cases and those with recent outbreaks.
Spatial visualization highlights the concentration of cases in areas classified as high incidence.The places with the most records are Aldea Boro and Aldea Jagupiru and the neighborhoods of Jardim Novo Horizonte, Jardim Jockey Club, Parque das Naques II, Jardim Florida, Jardim Agua Boa, Vila Cachorinha, Vila Industrial and Gemslord.
As shown on the maps used to monitor the disease, these areas are now considered priorities for surveillance and control efforts.
The integration of good activities supports the content of the high-level activity, allowing effective activities such as home visits, birth removal and training.
This work is the result of a collaboration between the UFMS (Federal University of Mato Grosso do Sul) CPAN geoprocessing laboratory and the city of Dourados.This project combines technical knowledge and spatial analysis to strengthen epidemic response.
Epidemiological report - updated data up to 2 April 2812 reports of chikungunya in the country.Of this total, 1,198 cases have been recorded, 430 have been disposed of and 1,184 are under investigation.The largest concentration is in indigenous villages, which is 822 recorded cases, which is 68.6% of the total.
Five deaths were also recorded in the municipality, all among the indigenous population, which reinforces the seriousness of the scenario in these municipalities.
Given the spread of the disease, the federal government stepped up its response by setting up a situation center in Brasília on March 25 with permanent meetings to monitor and coordinate measures.
In indigenous areas, actions take place in an integrated manner between different ministries and federal agencies, in addition to the Special Indigenous Health District of Mato Grosso do Sul (DSEI-MS).This structure employs 210 indigenous health workers and 150 indigenous health workers, with enhanced logistical support, including vehicles and field teams.
Measures include training of specialists from the municipal and local network, standardization of clinical protocols and intensification of health education.It is also planned to send preventive messages through WhatsApp to more than 234,000 residents in Portuguese and translated into local languages.
In terms of assistance, the national chikungunya protocol has been implemented and teams have been trained to identify critical cases early.
The federal response also includes a financial contribution of over R$3.1 million.Resources are allocated to humanitarian aid, urban cleaning, epidemiological surveillance and disease control.
Since mid-March, the SUS national force has been operating in the municipality, mobilizing 40 professionals.To date, 1,288 clinical consultations have been carried out, 68 evacuations in more complex units and 225 home visits.
The teams work with local and state authorities, restoring the flow of services and expanding the robust investigation of cases, particularly in more vulnerable areas.
Fight against the vector. Approximately 95 specialists work directly to control the Aedes aegypti mosquito.From March 9 to 16, 4,319 properties were inspected, finding 1,004 mosquito outbreaks, mostly in containers of standing water, garbage and tires.
In addition to actions at strategic points such as schools and health units, pesticide applications were also carried out using UBV (Ultra Low Volume) equipment.
Community solidarity led to the collection of four bucket trucks to remove large amounts of waste.This work is supported by the support of the Brazilian Army, which is already working with army and city vehicles.
Another measure adopted is the installation of EDL (Larvicide Distribution Stations).Out of the thousand units sent, 150 have already been installed in priority areas.
Actions in Indigenous Communities – FUNAI (National Foundation of Indigenous Peoples) also works with actions targeting food security and access to water.A plan has been made to distribute 6,000 rice donations between April and June.
In addition, the water supply in the municipalities of Jaguapiru and Bororó will be expanded in order to improve irrigation conditions and reduce the risks associated with the breeding of mosquitoes.
