In January 2026, the state of Paraíba in Brazil recorded 317 probable cases of arboviral diseases, with the majority being attributed to dengue fever. The data was released in an Epidemiological Bulletin by the Paraíba State Health Department (SES), which analyzed numbers up until February 6. Out of the total cases, 292 were confirmed as dengue, highlighting ongoing public health concerns in the area, while 25 cases were linked to chikungunya. Notably, no zika cases were reported in that timeframe, and only one dengue-related death is currently under investigation.

The health department noted that the highest incidence of cases was observed in the municipalities of João Pessoa and Princesa Isabel, indicating potential hotspots for transmission. The presence of dengue serotypes 2 and 3 in the region was also highlighted, which may complicate ongoing public health responses. To combat the spread of these diseases, SES has emphasized the importance of eliminating mosquito breeding sites, urging residents to take preventive measures against mosquito bites and stagnant water accumulation.

This uptick in arboviral cases in Paraíba marks a significant concern for public health authorities, as the state continues to navigate its response strategies amidst climate variability and urbanization, which can exacerbate mosquito proliferation. The SES is likely to monitor this situation closely, adjusting its public health campaigns to address community risk factors while considering potential pressures on health services as case numbers rise.
