Abstract

Objective: Our goal is to provide a detailed description of this hypothetical epidemiological model, which will enable us to develop an effective contingency plan.

Methods: Retrospective, observational cohort study. Information collected through epidemiological surveys of OAB patients from SE23 to SE31/2020. Sociodemographic characteristics are recorded (sex, education, occupation, affiliation to the health system, trips outside the RM [VFRM]), eating habits (consumption of food outside the home [AFH], in public [AVP] and of seafood and fish). s were calculated, and an epidemic curve was constructed graphically.

Results: 718 VHA in SE 20-31/2020. 449 VHA in SE23/2020: TA: AFH: 30.6 %, AVP: 45.1 %, AMP: 38 %. 673 VHA in SE25/2020: 37.2 % had STIs. 718 VHA in SE28/2020, with 421 responses: 84.3 % men (n=355), 57.9 % university education, 40.9% professionals and 59.1 % belonged to the private health system. 78.6 % not VFRM. Of the men, 84.3 % AS, 63.1 % homosexuals where 97.3 % SOA. In SE31/2020 VHA was highest among those 25-34 years of age.

Conclusions: HAV affected SOA homosexual men more and secondly, transmission through food. Epidemiological surveillance, health promotion and prevention, is essential to prevent outbreaks in these segments.
