Resumo Objetivo: Estabelecer protocolo para realização de autópsias minimamente invasivas (AMIs) na detecção de óbitos por arboviroses e relatar dados preliminares desse protocolo no Ceará, Brasil. Métodos: Médicos patologistas foram treinados em AMI. Resultados: Estabeleceu-se protocolo para AMI, definindo-se critérios para amostras a serem coletadas, suas formas de armazenamento e diagnóstico, segundo o tipo de amostra biológica; em três meses, foram realizadas 43 AMIs, das quais 21 (48,8%) chegaram ao Serviço de Verificação de Óbito (SVO) com hipótese diagnóstica de alguma arbovirose e sete (16,3%) foram confirmados (seis de chikungunya; uma de dengue); também foram confirmados casos de covid-19 (n = 9), tuberculose (n = 5), meningite (n = 4), criptococose (n = 1), doença de Creutzfeldt-Jakob (n = 1), neoplasia de mama (n = 1) e raiva humana (n = 1). Conclusão: O protocolo implantado permitiu a captação de um maior número de óbitos suspeitos de arboviroses, além da confirmação de outras patologias de interesse da vigilância.

Abstract Objective: To create a protocol for performing minimally invasive autopsies (MIA) in detecting deaths from arboviruses and report preliminary data from its application in Ceará state, Brazil. Methods: Training was provided to medical pathologists on MIA. Results: A protocol was established for performing MIA, defining criteria for sample collection, storage methods, and diagnoses to be carried out according to the type of biological sample; 43 MIAs were performed in three months. Of these, 21 (48.8%) arrived at the Death Verification Service (SVO) with arboviruses as a diagnostic hypothesis, and seven (16.3%) were confirmed (six chikungunya cases and one dengue case); cases of COVID-19 (n = 9), tuberculosis (n = 5), meningitis (n = 4), cryptococcosis (n = 1), Creutzfeldt-Jakob disease (n = 1), breast cancer (n = 1), and human rabies (n = 1) were also confirmed. Conclusion: The protocol implemented enabled identification of a larger number of suspected arbovirus-related deaths, as well as confirmation of other diseases of interest for surveillance.

Abstract INTRODUCTION: COVID-19 emerged in late 2019 and quickly became a serious public health problem worldwide. This study aim to describe the epidemiological course of cases and deaths due to COVID-19 and their impact on hospital bed occupancy rates in the first 45 days of the epidemic in the state of Ceará, Northeastern Brazil. METHODS: The study used an ecological design with data gathered from multiple government and health care sources. Data were analyzed using Epi Info software. RESULTS: The first cases were confirmed on March 15, 2020. After 45 days, 37,268 cases reported in 85.9% of Ceará’s municipalities, with 1,019 deaths. Laboratory test positivity reached 84.8% at the end of April, a period in which more than 700 daily tests were processed. The average age of cases was 67 (<1 - 101) years, most occurred in a hospital environment (91.9%), and 58% required hospitalization in an ICU bed. The average time between the onset of symptoms and death was 18 (1 - 56) days. Patients who died in the hospital had spent an average of six (0 - 40) days hospitalized. Across Ceará, the bed occupancy rate reached 71.3% in the wards and 80.5% in the ICU. CONCLUSIONS: The first 45 days of the COVID-19 epidemic in Ceará revealed a large number of cases and deaths, spreading initially among the population with a high socioeconomic status. Despite the efforts by the health services and social isolation measures the health system still collapsed.
