BackgroundSeoul virus (SEOV) is a member of hantavirus family, which is transmitted to humans by Rattus rattus and Rattus norvegicus. Diagnosing SEOV infection is difficult because the clinical presentations are often undifferentiated with other viral or bacterial infections and assays to test antibodies seroconversion and RNA detection are not available in resource-limited setting like Indonesia.Case presentationWe report two confirmed cases of SEOV infection from Indonesia. Here, we illustrate the clinical presentations, hematology and biochemistry profiles, and outcomes of the two cases. Phylogenetic analysis revealed that SEOV sequences have highest homology to isolates obtained from rodents in Indonesia.ConclusionsThis report highlights the importance of considering SEOV infection in febrile patients with lymphopenia, thrombocytopenia, and elevation of liver enzyme despite the absence of hemorrhagic manifestations and renal syndromes. The public health importance of rodent-borne diseases such as SEOV infection urges an integrated epidemiological surveillance both in humans and rodents in Indonesia.Electronic supplementary materialThe online version of this article (10.1186/s12879-018-3482-1) contains supplementary material, which is available to authorized users.
BackgroundPneumonia remains the leading killer with an estimated of 922,000 fatalities or 15% of all deaths in <5-year-old children in 2013. Mortality can be reduced by providing appropriate treatment to the pathogens. The objectives of this study were to describe the causes of pneumonia that may change after the introduction of vaccines and to identify biomarkers to differentiate between bacterial and viral infection.MethodsA 2-year multicenter cohort study of children between 2-month–5-year old with pneumonia has been conducted in three hospitals in Indonesia since July 2017. Demographics, clinical, laboratory, radiology, treatment data, have been recorded. Blood, urine, nasopharyngeal swab, sputum/induced sputum, specimens have been collected for biomarkers, culture, molecular and serological tests.ResultsThree-thirty from 99 pneumonia subjects screened were enrolled in this study since July 2017. 20 (60.6%) subjects had bacterial and viral coinfection, 10 (30.3%) subjects with bacterial infection, two (6.0%) subjects with viral infection, and one (3.0%) subject had unknown etiology. Demography, clinical signs and symptoms, disease and vaccination history, laboratory, and radiological evaluation are shown in Table 1. The etiologies of pneumonia are described in Figure 1.ConclusionMixed viral and bacterial infection were predominant. Several atypical pathogens were identified. No significant different in biomarkers between viral, bacterial and mixed infection groups was found. This finding highlights the need to improve diagnostic capacity to aid clinicians in pneumonia management.
