“…Previous studies in Brazil have reported a wide range of olfactory dysfunction prevalence in COVID-19, ranging from 13.1 to 83.9% [19][20][21][22][23]. However, these studies were based on relatively small cohorts, which may not have been representative of the entire population.…”

Objective: To determine the prevalence and factors associated with olfactory dysfunction in individuals with Covid-19 in the first two years of the pandemic in the Brazil. Materials And Methods: This is a prevalence study involving the confirmed cases of Covid-19 recorded in the municipality between the years 2020 and 2021. Individuals symptomatic for Covid-19, with a positive laboratory result and aged 12 or older, were included in this study. Measures of central tendency and dispersion were used in the description of continuous variables and frequency was used for categorical variables. The Shapiro-Wilk test was used to evaluate data distribution. Results: Data from 20,669 individuals were analyzed. The prevalence of olfactory disorders was 17.9% and increased from 11.5% to 21.9% between 2020 and 2021. A female gender predominance was observed among individuals who reported anosmia, with 61.1% (n = 564) in 2020 and 61.7% (n = 1713) in 2021. On the other hand, the median age of individuals with olfactory disorders was lower than that of the group without disorders (35 [IQR 27-46] vs. 39 [IQR 29-50]; p < 0.001). Smell disturbances were present in 18.2% (n=3634) of patients who recovered and in 7.1% (n = 38) of those who died. Furthermore, in 2021, a prevalence rate of 30.6% for olfactory disorders was linked to obesity as a comorbidity. Conclusion: The prevalence of olfactory disorders was lower compared to other studies, with cough and fever being negatively related to olfactory dysfunction, and headache, coryza, and taste disorders being positively related. Obesity was the only associated comorbidity.

This article aims to estimate the excess of deaths in the years 2020 and 2021 in Mato Grosso state, in the state capital and in the countryside, according to gender and age group. Data was extracted from DATASUS/Ministry of Health website for the period from 2015 to 2020 and from the website of the State Department of Health - Data Warehouse System (DW) for 2021. Non-fetal deaths by natural causes of residents in Mato Grosso were analyzed and the analyses were broken down into countryside and state capital (Cuiabá). The variables selected were age group, gender, month of occurrence, and underlying cause of death. Excess mortality was calculated using generalized additive quasi-Poisson model adjustments with correction for overdispersion. A 30% excess of deaths was identified in 2020, with the state capital recording the highest estimate, in older age groups, and between the months of July and September. In 2021, the expected number of deaths was 57% higher, with the double in the younger age groups in the countryside. The study showed different demographic profiles of excess deaths in the years 2020 and 2021 during COVID-19 pandemic and distinct patterns between countryside and state capital, suggesting inequalities that may have caused impact on different risks.
