Smoking is a chronic condition that negatively impacts lung health and may increase the risk of aggravation in patients with COVID-19. The study sought to analyze the relationship between the rates of cases and deaths caused by COVID-19 and the percentage of smokers in Brazilian capitals. A cross-sectional and analytical research was carried out, with data relating smoking and cases/deaths by COVID-19, from the databases of the Surveillance of Risk Factors and Protection for Chronic Diseases by Telephone Survey (VIGITEL) 2019) and Coronavirus Panel of the Health Surveillance Department. Bivariate analyzes showed positive correlations between female smokers and the coefficient of cases accumulated by COVID-19 in the capitals of the Midwest region (r=0.957, p=0.043) and also among male smokers and coefficient of deaths by COVID-19, in the capitals of the Northeast (r=0.706; p=0.034). Expanded studies are needed to identify the profile of smokers affected by COVID-19 and its evolution, since the relationship between smoking and COVID-19 indicated a worse prognosis in the Northeast region. This study may bring contributions to support the verification of the prognosis of COVID-19 in smokers, favoring a closer look at the smoker affected by this infection, in order to seek alternatives to reduce unfavorable clinical outcomes. Objetivo: Analisar a relação entre casos e óbitos por COVID-19 e o percentual de tabagistas nas capitais e regiões do Brasil. Métodos: Realizou-se estudo ecológico nas regiões brasileiras do número de casos e óbitos por COVID-19, de março a dezembro de 2020, e a prevalência de tabagismo em 2019, a partir dos bancos de dados do Painel Coronavírus da Secretaria de Vigilância em Saúde e do Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL – 2019). Com informações extraídas em janeiro de 2021, calcularam-se os coeficientes de incidência e mortalidade por COVID-19 por capital brasileira e região, bem como se utilizou a correlação de Pearson para verificar a relação entre as variáveis do estudo. Adotou-se nível de significância de 5%. Resultados: Análises bivariadas mostraram correlações positivas entre tabagistas do sexo feminino e coeficiente de incidência de COVID-19 nas capitais da região do Centro-Oeste (r=0,957; p=0,043), e entre fumantes do sexo masculino e coeficiente de mortalidade de COVID-19 nas capitais do Nordeste (r=0,706; p=0,034). Conclusão: O tabagismo teve impacto na incidência de casos e óbitos por COVID-19 em diversas capitais brasileiras, alertando que o fumo pode ser fator de predisposição e agravamento do estado clínico dos pacientes.

Currently, the consequences of coronavirus disease 2019 (COVID-19) in children of mothers affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during pregnancy are unknown. In addition to pregnancy risks, the impact of COVID-19 on the health of these children can occur in the short, medium, and long term. Initial data reveal a low risk of vertical transmission during the third trimester of pregnancy and through breastfeeding. However, despite this low risk, cases of neonatal COVID-19 have already been reported in the literature. Historically, other viral infections during pregnancy have been associated with an increased risk of neuropsychiatric diseases in the offspring of affected pregnant women, even in the absence of fetal infection. This study aimed to review the impact of viral infections on the offspring of mothers affected in the perinatal period and discuss and determine measures for the possible consequences of COVID-19 in the offspring of pregnant women infected with SARS-CoV-2.
