What is it about?
This study analyzes Brazil's early warning systems to detect SARS-CoV-2 among international travelers in early 2020 in Brazil. Brazil targeted symptomatic travelers from a restricted list of countries. Only 34.2% of confirmed SARS-CoV-2 cases were in travelers from countries on the designated country list. Among all travelers, 75.8% of suspected cases were not investigated. Before community transmission, nearly all close contacts (96%) were not investigated. RT-PCR tests were reported for 38.1% of hospitalized travelers.
