Abstract Background To assess the impact of the social isolation index on the number of infections and deaths by COVID-19 in the state of São Paulo (Brazil). Methods Daily isolation data, obtained through geolocation information by mobile phone, were evaluated together with the number of daily infections and deaths by COVID-19 in the state of São Paulo. The study was conducted from February 26 to May 19, 2020. The data were modeled through the vector autoregression (VAR) model. Results The isolation index has an effect of approximately 5% in variation in the number of infections, and 7% in the number of deaths. The impulse response function (IRF) caused a drop of 0.15% in the number of new cases/day, and 0.17% in the number of deaths/day following a shock in the isolation index. For both cases, this effect occurred 1 day after the shock and stabilized after 10 periods. An increase of 1% in the isolation index led to a reduction of 6.91% in new cases and 6.90% in the number of deaths. The 30 cumulative day reduction reached 22.72% in terms of transmission and 35.39% for deaths. Conclusions The social isolation index is related to deaths and infections from SARS-CoV-2. Although distancing measures are accompanied with impacts on the economy and the emergence of other morbidities, the benefits caused by the reduction in the speed of contagion are significant. The adoption of distancing measures has a substantial impact on the number of infected individuals and deaths by COVID-19.

Abstract Since January 2020, some studies have been reporting a reduction in air pollution in several countries due to social isolation measures, which have been adopted in order to contain the coronavirus outbreak progress (Covid-19). This study aims to evaluate the change in the atmospheric pollution levels by NO and NO2 in São Paulo city in the social isolation period. The NO and NO2 hourly concentrations were obtained through air quality monitoring stations from CETESB, from January 14 to April 12, 2020. Mann-Kendall and the Pettitt tests were performed in the air pollutants time series. We observed an overall negative trend in all stations, indicating a decreasing temporal pattern in concentrations. Regarding NO, the highest decrease rates were observed in Congonhas (-6.39 µg.m-3month-1) and Marginal Tietê (-6.19 µg.m-3month-1) stations; regarding NO2, the highest rates were observed in Marginal Tietê (-4.45 µg.m-3month-1) and Cerqueira César (-4.34 µg.m-3month-1) stations. In addition, we identified a turning point in the NO and NO2 series trends that occurred close to the start date of the social isolation period (March 20, 2020). Moreover, from statistical analysis, it was found that NO2 is a suitable surrogate for monitoring economic activities during social isolation period. Thus, we concluded that social isolation measures implemented in March 20, 2020 caused significant changes in the air pollutants concentrations in São Paulo city (as high as -200% in NO2 levels).

Introduction: COVID-19 is a highly transmissible virus that is causing very serious problems in the health of the world, generating major political and financial problems. There are numerous risk factors related to this disease, ranging from morbidities to social and family issues. Objective: to evaluate the effects of the social isolation generated by Covid-19 on the quality of life in the population of two Brazilian cities. Methods: cross-sectional study. The research was carried out in two different cities of the Brazilian confederation. One in Santo André, São Paulo and the other in Rio Branco, Acre, both in Brazil. This is a survey with an online platform, using the drive’s Google Forms tool to assess the population’s quality of life through the SF-36 protocol. The selection was carried out randomly in both groups (Acre and São Paulo), having respectively 109 and 62 participants in this first moment. Results: regarding gender, women are in greater numbers participating in the city of Santo André, São Paulo than in Rio Branco, Acre, both in Brazil, with (80.6% and 48.6%), respectively. Likewise, in relation to the age group Santo André has an average age younger than in Rio Branco. When we compared the dimensions between the two states, performing a Mann-Whitney statistical analysis, statistical differences appeared in three dimensions, which were functional capacity, pain, and vitality, with better quality of life in these three domains for the city of Rio Branco. Conclusion: the city of Rio Branco, Acre, Brazil, has a positive score when compared to the city of Santo André, São Paulo, Brazil, in most of the domains analyzed.

Introduction: With the arrival of the SARS-CoV-2 (Coronavirus 2 of severe acute respiratory syndrome) pandemic in Brazil, especially in the city of São Paulo, there was a need to apply social isolation policies associated with testing, covering all municipalities. The Clinical Analysis Laboratory of Centro Universitário FMABC was one of the first laboratories to receive certification and qualification to perform RT-PCR (reverse transcriptase reaction followed by polymerase chain reaction) tests in the metropolitan region of São Paulo. Objective: Aim to analyze the influence of adopting social isolation on the incidence of positivity in COVID-19 tests in the metropolitan region of São Paulo, Brazil. Methods: a descriptive study carried out from March to May 2020, epidemiological data were collected from each unit served and organized by the data controllership team of the Clinical Analysis Laboratory of FMABC. Epidemiological, demographic, and laboratory data were extracted from the Matrix® outpatient data management system. Clinically suspected cases and confirmed by laboratory tests (RT-PCR and serological tests) were entered. The tests were divided into serological tests using the RT-PCR molecular test, on samples of nasopharyngeal mucosal scrapings collected with sterile Swab. Results: It were evaluated PCR test and antibody presence (IgA, IgM and IgG) in blood samples of 16.297 patients. 22.718 tests were performed for the diagnosis of COVID-19, both RT-PCR (10.410 tests) and serological tests to detect anti-SARS-CoV-2 antibodies, IgA, IgM and IgG, a total of 16.297 patients were assessed, 63% women and 37% men. It was observed that the social isolation policies adopted during this period contained the massive expansion of contamination, at least while the social isolation rates were above 55%. Conclusion: The data of this study demonstrated the effectiveness of social isolation in containing the positive contamination of SARS-CoV-2 in the metropolitan region of São Paulo, at least for the first three months.

INTRODUCTION: An important issue to be discussed by researchers, managers and other members of the crisis committees to face the pandemic are the repercussions of social detachment, such as domestic accidents with child and adolescent victims. OBJECTIVES: To describe domestic accidents in childhood and adolescence during the period of social isolation in the city of São Paulo-SP, regarding the characteristics of individuals, the event and the evolution of the case. METHODS: Cross-sectional, descriptive study, based on data on hospitalizations for external causes, accidents and violence in the city of São Paulo. Data were collected in the hospital information system and the violence and accident information system. The period used for the study was from January to May 2020. RESULTS: 4,169 accidents were registered among children and adolescents living in the city of São Paulo, and consequently, resulting in the diagnosis of injury, trauma and head injury. Among the victims, predominantly male and the main type of accident was falls. CONCLUSION: Given the above, the severity of COVID-19 in Brazil, in the city of São Paulo and in the world, and the need for efforts to reduce the speed of virus transmission at the population level and to reduce the incidence of the disease, so far, social detachment is part of the set of measures necessary to achieve these goals, permanent health education for parents, family members and society is necessary to prevent domestic accidents.

Background: In light of the few reports from intertropical latitudes and their conflicting results, we aimed to replicate and update the investigation of seasonal patterns of suicide occurrences in the city of São Paulo, Brazil. Methods: Data relating to male and female suicides were extracted from the Mortality Information Enhancement Program (PRO-AIM), the official health statistics of the municipality of São Paulo. Seasonality was assessed by studying distribution of suicides over time using cosinor analyses. Results: There were 6,916 registered suicides (76.7% men), with an average of 39.0 ± 7.0 observed suicides per month. For the total sample and for both sexes, cosinor analysis estimated a significant seasonal pattern. For the total sample and for males suicide peaked in November (late spring) with a trough in May–June (late autumn). For females, the estimated peak occurred in January, and the trough in June–July. Conclusions: A seasonal pattern of suicides was found for both males and females, peaking in spring/summer and dipping in fall/winter. The scarcity of reports from intertropical latitudes warrants promoting more studies in this area.
