Rio de Janeiro Arbovirus Control Efforts Continue in 19 Neighborhoods
São Paulo Intensifies Dengue Prevention with Street-Level Agent Visits
The São Paulo Municipal Health department (SMS) is expanding its preventative measures against arboviruses – dengue, Zika, and chikungunya – thru increased home visits by health agents as of January 20, 2026.
Details of the “SVS na Rua” Strategy
The SMS initiative, known as “SVS na Rua” (SVS on the Street), aims to proactively identify and eliminate breeding grounds for the Aedes aegypti mosquito, the primary vector for these diseases. Health agents are visiting residences to educate residents about preventative measures, inspect properties for standing water, and offer guidance on eliminating potential mosquito habitats. This strategy represents a focused effort to reduce the incidence of arboviral diseases within the city.
Evidence of Increased Activity
According to a statement released by the SMS on January 18, 2026, the number of health agents participating in “SVS na rua” has increased by 30% compared to the same period in 2025. In 2025, São Paulo recorded 1,457 confirmed cases of dengue fever, according to data from the State Health Secretariat (Secretaria Estadual da Saúde). The SMS anticipates a potential surge in cases during the rainy season (December-March) and is bolstering its preventative efforts accordingly. The initiative is being supported by a budget of R$ 5 million allocated for agent training and resource distribution.
Quote from the SMS: “The ‘SVS na Rua’ strategy is crucial for interrupting the transmission cycle of arboviruses and protecting the health of our population,” stated dr. Carina Bottoni,Coordinator of Vector Control at the SMS,in a press conference on January 19,2026.
