COVID-19 mortality in Brazil, 2020-21: consequences of the pandemic inadequate management

Abstract

Background The COVID-19 pandemic brought countless challenges to public health and highlighted the Brazilian health system vulnerabilities in facing the emergency. In this article, we analyze data on COVID-19-related deaths in 2020-21 to show the epidemic consequences in Brazil. Methods The Mortality Information System and the Live Birth Information System were the primary information sources. We used population estimates in 2020-21 to calculate COVID-19 specific mortality rates by age, sex, and educational level. Considering the total number of COVID-19 deaths in 2020-21, the COVID-19 proportional mortality (%) was estimated for each age group and sex. A graph of the daily number of deaths from January 2020 to December 2021 by sex was elaborated to show the temporal evolution of COVID-19 deaths in Brazil. In addition, four indicators related to COVID-19 mortality were estimated: infant mortality rate (IMR); maternal mortality ratio (MMR); number and rate of orphans due to mother’s COVID-19 death; the average number of years lost. Results The overall COVID-19 mortality rate was 14.8 (/10,000). The mortality rates increase with age and show a decreasing gradient with higher schooling. The rate among illiterate people was 38.8/10,000, three times higher than a college education. Male mortality was 31% higher than female mortality. COVID-19 deaths represented 19.1% of all deaths, with the highest proportions in the age group of 40-59 years. The average number of years lost due to COVID-19 was 19 years. The MMR due to COVID-19 was 35.7 per 100,000 live births (LB), representing 37.4% of the overall MMR. Regarding the number of orphans due to COVID-19, we estimated that 40,830 children under 18 lost their mothers during the epidemic, with an orphans’ rate of 7.5/10,000 children aged 0-17 years. The IMR was 11.7 per 1000 LB, with 0.2 caused by COVID-19. The peak of COVID-19 deaths occurred in March 2021, reaching almost 4000 COVID-19 deaths per day, higher than the average number of deaths per day from all causes in 2019. Conclusions The delay in adopting public health measures necessary to control the epidemic has exacerbated the spread of the disease, resulting in several avoidable deaths.

Can SARS‐CoV‐2 screening in oral biopsies aid epidemiological surveillance?

“…The lack of massive testing contributed to the devasting SARS-CoV-2 epidemic outcome in the country. 1 Despite the intense efforts of Brazilian research groups in conducting viral genomic surveillance, 2 the minute Federal resources earmarked for science avoided adequate asymptomatic epidemiological surveillance. 3 The high cellular expression of the angiotensin-converting enzyme 2 (ACE2) receptor detected in salivary glands and tongue epithelial cells gave the oral cavity the title of the main reservoir of SARS-CoV-2 in the human body.…”

“…Brazil has the fifth highest number of confirmed COVID‐19 cases worldwide and second in deaths, following the USA (WHO, 2023). The lack of massive testing contributed to the devasting SARS‐CoV‐2 epidemic outcome in the country 1 .

COVID-19 Patterns in Araraquara, Brazil: A Multimodal Analysis

“…Such strategies exposed, in particular, the somewhat unexpected size of the political bias regarding the spread of SARS-CoV-2 and the mortality rate of COVID-19 in Brazil, surpassing other important epidemiological elements such as the level of poverty and the mutation of the virus. People were constantly persuaded not to adopt restrictive measures [ 25 , 26 ]. Furthermore, the fomentation of anti-COVID-19 measures by the federal government amplified the challenges of monitoring the spread of the virus, to the extent that the daily count of cases and deaths was not properly updated.…”

Iniquidades das mortes violentas e de COVID-19 negligenciadas pelo Estado brasileiro

“…No decorrer da obra os autores criticam a forma neutra de a OMS tratar o tema "mortes violentas" -classificando-as no grupo "morte por causa externa", sem especificar quaisquer condições que as determinaram socialmente -e a indiferença governamental sobre as mortes por COVID-19. A maioria dos homicídios e feminicídios, suicídios, acidentes de trânsito e do trabalho são ocorrências previsíveis e preveníveis, assim como cerca de dois terços das mortes por COVID-19 poderiam ter sido evitados, não fosse o negacionismo do governo neoliberal que protelou a aquisição de vacinas 3 .…”
