According to the epidemiological report, 187 municipalities recorded 9,242 probable cases of dengue fever in 2022, while over the same period of 2021, 1,093 reports were made by 75 municipalities. The bulletin also reports that the system has confirmed three deaths in the state, all in the municipality of Teresina.

Data from the 19th epidemiological week also show that the five municipalities with the highest incidence of dengue fever are Novo Santo Antônio, Antônio Almeida, Patos do Piauí, Simplício Mendes and Tanque do Piauí.


Regarding chikungunya cases, the survey shows that in 2021, there were only 58 confirmed cases. In 2022, the same period, the number of cases already reaches 1,930. According to the data, the state has not recorded any deaths from chikungunya since 2018.

The bulletin presents Simplício Mendes, Alagoinha do Piauí, São Julião, Monsenhor Hipólito, Alegrete do Piauí, Jaicós, Campo Grande do Piauí and Patos do Piauí as the municipalities with the highest incidence of chikungunya cases.

The Secretary of State for Health Neris Júnior says that the increase in cases is already being monitored and that the technical teams of the secretariat are giving full support to the municipalities.

“This pattern of increase in cases compared to the same period last year repeated itself every week, detecting this increase, our team worked with the municipalities, provided technical support, reinforced the necessary measures and sent the service smoke to the fight against dengue fever and chikungunya in our state,” the secretary noted.

Ocimar Alencar, supervisor of entomology at Sesapi, points out that in addition to the measures taken by municipal and state officials, the participation of the population is essential to reduce cases.

“We repeat this point every week, but the truth is that it is essential that the fight against dengue be more effective. We are in a period of seasonality of the virus where an increase in cases was already expected, however the level recorded us raises concerns for both dengue fever and chikungunya.The literature and our surveys show that 80% of mosquito breeding sites are present in the domestic environment, so it is essential that the population helps the public authorities by cleaning their homes and by preventing the emergence of new environments conducive to the development of the mosquito.”, says Ocimar.


Always looking for other ways to extend support to the municipalities of Piauí in the fight against dengue and chikungunya and in the reduction of cases in Piauí, the teams of the Center for Strategic Information on Health Surveillance ( Cievs) held meetings and trainings with municipalities aimed at adjusting the issue of data recording and better adaptation measures in each region.

“Our team is already visiting municipalities and talking to their representatives and those of neighboring municipalities. This week it is planned to work with Piripiri, Campo Maior and Parnaíba, maintaining this direct contact and thus defining the best strategies for the epidemiological profile of each region, said Amélia Costa, coordinator of Cievs and the epidemiological sector of Sesapi .

Sesapi has also sent the municipalities a technical note on the points that each municipality must adopt to request the smoke bomb. So far, the state has already sent a smoke car to support 40 municipalities across the state.

We evaluated the epidemiological profile of this municipality to verify the need to use or not to smoke in this place. This measure helps us to verify the progress of the confrontation throughout the state, in addition to guaranteeing the correct use of the chemical used to eliminate mosquitoes,” explained Ocimar Alencar.
