Infectious diseases transmitted by animals beyond symptoms, how socioeconomic and environmental conditions can influence them

Vector-borne diseases, such as dengue, chikungunya, zika, and leishmaniasis, represent a global public health challenge. This study aimed to understand the impact of socioeconomic, environmental, and healthcare access variables on the incidence of infectious diseases from 2012 to 2021, investigating patterns and correlations. Variables analyzed included the number of healthcare facilities, average income, population size, Gross Domestic Product (GDP), and accumulated deforestation. Multiple linear regression and correlations were used, with data from the Notifiable Diseases Information System (SINAN) and the National Institute for Space Research (INPE). Dengue showed a strong correlation with GDP, the number of healthcare facilities, and deforestation. Chikungunya was associated with population, GDP, and deforestation. Zika showed correlations with population growth and deforestation. Leptospirosis was negatively influenced by healthcare facilities and GDP, while hantavirus infection was inversely related to population growth and healthcare facilities. Leishmaniasis had positive correlations with GDP, healthcare facilities, and deforestation. This study reveals complex interactions between socioeconomic, environmental, and health variables in the incidence of infectious diseases. Understanding these patterns is crucial for formulating effective public policies, highlighting the need for integrated and holistic strategies in the control and prevention of these diseases.
