Objective: to describe the evolution of indicators and capacity for health care in the initial phase of the COVID-19 epidemic in the Northeast region of Brazil. Methods: this was a descriptive study based on COVID-19 case epidemiological bulletins released by the Ministry of Health up until April 1 st , 2020. The incidence rate, lethality and number of cumulative daily cases were calculated. Results: 1,005 confirmed cases of COVID-19 were identified, most of them in Ceará and Bahia states. The incidence rate was 1.8/100,000 inhabitants and lethality was 2.7%. Ceará was the state with the highest number of cases, with 29.6 new cases per day on average. Average intensive care bed availability in the Northeast region (1.04/10,000 inhab.) was below the national average (2.8/10,000 inhab.). Conclusion: the indicators suggest that COVID-19 impact is heterogeneous and signal the challenges for health systems in the Northeast Region.
This study showed that laboratory markers of recent infection by dengue, Zika or chikungunya arboviruses were detected in the biological samples of approximately one-third of patients with encephalitis, myelitis, encephalomyelitis or Guillain-Barré syndrome, in a surveillance programme in Piauí state, Brazil, between 2015-2016. Fever and myalgia had been associated with these cases. Since in non-tropical countries most infections or parainfectious diseases associated with the nervous system are attributed to herpesviruses, enteroviruses, and Campylobacter jejuni, the present findings indicate that in tropical countries, arboviruses may now play a more important role and reinforce the need for their surveillance and systematic investigation in the tropics.
A leishmaniose visceral (LV) ou calazar é uma das principais doenças tropicais negligenciadas, de grande importância devido ao caráter letal desta zoonose causada por protozoários do gênero Leishmania. Objetivou-se analisar a tendência temporal dos casos de LV no Estado do Piauí, Brasil, de 2008 a 2018, inserindo-o dentro do período total de 1971 a 2018. Utilizaram-se dados do Sistema de Informação de Agravos de Notificação (SINAN) e do Sistema de Informações sobre Mortalidade (SIM). Para análise da carga da doença, foram coletados dados do Instituto de Métricas e Avaliação em Saúde através do estudo Carga Global de Doenças, Lesões e Fatores de Risco. Foi empregada a análise de regressão Prais-Winsten. Foram registrados 2.374 casos com provável local de infecção no Piauí e 2.492 casos em residentes do estado. A série histórica analisada, de 1971 a 2018, reafirma o caráter cíclico da doença, pela presença dos picos epidêmicos identificados em 1983 e 1984, 1993 e 1994, 2003 e 2004 e 2013 e 2014. Não foram identificadas alterações significativas na tendência dos coeficientes de incidência, mortalidade e letalidade no estado. No entanto, houve aumento significativo do coeficiente de incidência no Território de Desenvolvimento (TD) Chapada das Mangabeiras (variação percentual anual de 17,5%) e redução no TD Vale do Sambito (-18,3%) e TD Vale do Rio Guaribas (-8,1%). A LV tem a maior carga de doença medida em anos de vida ajustados por deficiência entre as doenças tropicais negligenciadas do estado. Recomenda-se o aprimoramento das medidas de vigilância e controle do agravo.
