Summary
The world population was surprised by the discovery of a new virus belonging to the Coronaviridae family, which emerged in China and rapidly spread over the continents. SARS-CoV-2 has high morbidity, and the symptomatology triggered by the infection varies from non-specific clinical signs to severe pneumonia. Municipalities, especially the smaller ones, have their health surveillance dynamic, which requires the study of the dispersion of diseases and their characteristics as COVID-19. This study aimed to present the temporal distribution of SARS-CoV-2 diagnosis in the Regional Health Units (URS) – of Manhuaçu, Ponte Nova, and Ubá – from Minas Gerais, Brazil, from May to August 2020. Altogether, the URS are composed of 95 municipalities, with populations ranging from 2,000 to 99,000 inhabitants. Nasopharyngeal swab samples were collected from patients suspected COVID-19, by presenting symptoms or being in contact with confirmed COVID-19, including health and safety professionals. Both patient selection and collection of samples were performed by the Brazilian Unified Health System (SUS) and sent to the laboratory network of the Federal University of Viçosa (UFV). The diagnosis was performed by RNA isolation using the QiAamp Viral RNA Mini Kit (QIAGEN ®) and qPCR detection, using primers and probes recommended by the CDC (Centers for Disease Control and Prevention). In the period from April to August 2020, 10,498 COVID-19 diagnostic tests were done, at a ratio of 8.7 tests per 1,000 inhabitants. Among these, 2,016 were positive, in a proportion of 192 positives per 1,000 tests. This is considerably low based on the WHO recommendation, which advocates that only 5% of all tests can be positive. In our study, we found 19% of positive cases. August was the month with a greater percentage of positive cases, representing 7.4% of the total of tests performed throughout the period and 18% of the total analyses only in that month. The temporal variation of the diagnostic tests was 861.8%, with an increase from 482 tests in May to 4154 in August. The increase in testing proportion is due to the population testing demand and disclosure of virus dynamics. The cumulative incidence was 168 per 100,000 inhabitants and monthly incidences varied from 40.1 in May to 65 in August. The value is considerably lower when compared to the incidence of 2446.3 per 100,000 inhabitants in Brazil. This number reflects the increase in the testing rate of positives and their contacts, in addition to the increased circulation of the virus throughout the territory. The data presented showed that the URS of Manhuaçu, Ponte Nova, and Ubá have a higher testing rate when compared to the Brazilian testing rate, but its incidence is lower when compared to the national level. Thus, the pandemic in small municipalities does not behave similarly to the rest of the country. Financial Support: Ministério da Educação, Funed, CNPq, FAPEMIG, Capes,
