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.

Coinfection of SARS-CoV-2/Mycobacterium tuberculosis (MTB) in patients with HIV/AIDS has not been previously reported. Here, we present two cases of coinfection of SARS-CoV-2 and MTB in patients with HIV. The first case is a 39-year-old patient who was admitted with a 7-day history of fever, myalgia, headache, and cough. The second patient is a 43-year-old man who had a 1-month history of cough with hemoptoic sputum, evolving to mild respiratory distress in the last 7 days. Both patients already had pulmonary tuberculosis and subsequently developed SARS-CoV-2 infection during the 2020 pandemic. Nonadherence to antiretroviral treatment may have been a factor in the clinical worsening of the patients.

A doença do novo Coronavírus (Covid-19) é causada pelo SARS-CoV-2 e representa o agente causador de uma doença potencialmente fatal que tem se revelado um problema de saúde pública global. A pandemia causada pelo Covid-19 tem causado prejuízos severos nos sistemas de saúde em diversos países. Diante do grande número de pessoas infectadas e da ausência de tratamento específico, várias nações têm enfrentado superlotação em seus hospitais. Com a confirmação de casos desta doença no Brasil, várias ações têm sido tomadas por gestores públicos e privados, tanto a nível hospitalar quanto em nível de atenção primária, a fim de minimizar os impactos para o Sistema Único de Saúde (SUS). O presente artigo apresenta uma breve análise do papel da atenção primária na luta contra o Covid-19 em âmbito nacional, além do impacto em saúde pública e das futuras perspectivas. Com base no grande número de pessoas infectadas no mundo e a experiência de diversos sistemas de saúde, torna-se imperativo a adaptação e adequação do SUS na condução de mecanismos de resposta para pandemia, sendo a atenção primária peça fundamental neste processo

Introduction: Chikungunya infection presents with distinct clinical features depending on the patient age group. Methods: Medical records of children with positive IgM for the chikungunya virus who were hospitalized in a pediatric ward in Fortaleza, Ceará, Brazil were analyzed. Results: Fourteen children with a median age of 4 months (36 days to 15 years) were included. All patients presented with fever persisting for an average of 5 days. The joints were involved in 6 (42.8%) children, and 8 (57.1%) children presented with bullous rash. Conclusions: Systemic involvement and atypical clinical manifestations characterize severe forms of chikungunya infection in children.

Background The State of Ceará, in Northeastern Brazil, suffers from a triple burden of arboviruses (dengue, Zika and chikungunya). We measured the seroprevalence of chikungunya, dengue and Zika and its associated factors in the population of Juazeiro do Norte, Southern Ceará State, Brazil. Methods A cross-sectional study of analytical and spatial analysis was performed to estimate the seroprevalence of dengue, Zika and chikungunya, in the year 2018. Participants were tested for IgM and IgG against these three viruses. Those with IgM and/or IgG positive tests results were considered positive. Poisson regression was used to analyze the factors associated with positive cases, in the same way that the spatial analysis of positive cases was performed to verify whether the cases were grouped. Results Of the 404 participants, 25.0% (103/404) were positive for CHIKV, 92.0% (373/404) for flavivirus (dengue or Zika) and of these, 37.9% (153/404) samples were classified as probable dengue infection. Of those who reported having had an arbovirus in the past, positive CHIKV cases had 58.7% arthralgia (PR = 4.31; 95% CI: 2.06–9.03; p = 0.000) mainly in the hands, ankles and feet. Age over 60 years had a positive association with cases of flavivirus (PR = 1.29; 95% CI: 1.09–1.54; p = 0.000). Fever, muscle pain, joint pain and skin rash were the most reported symptoms (46.1, 41.0, 38.3 and 28.41%, respectively). The positive cases of chikungunya and dengue or Zika were grouped in space and the city center was most affected area. Conclusions Four years after the introduction of CHIKV, where DENV has been in circulation for over 30 years, 1/4 of the population has already been exposed, showing the extent of the epidemic. The measured prevalence was much higher than that reported by local epidemiological surveillance.
