The incidence of IMD is low and similar across the represented countries (< 0.2 cases per 10 0,0 0 0 persons per year), with the predominant serogroups of Neisseria meningitidis being B, W and Y, although serogroups A and X are present in some areas. Resistance to ciprofloxacin is also of concern, with the close monitoring of antibiotic-resistant clonal complexes (e.g., cc4821) being a priority. Meningococcal vaccination is only included in a few National Immunization Programs, but is recommended for high-risk groups, including travellers (such as pilgrims) and people with complement deficiencies or human immunodeficiency virus (HIV). Both polysaccharide and conjugate vaccines form part of recommendations. However, cost and misconceptions remain limiting factors in vaccine uptake, despite conjugate vaccines preventing the acquisition of carriage.

Background The incidence of COVID-19 is still rapidly increasing, but little is known about the prevalence and characteristics of fatal cases in children in Indonesia. This study aims to describe the characteristics of pediatric COVID-19 cases with fatal outcomes in Indonesia's tertiary referral hospital. Methods This is a cross-sectional study with data collected from the medical records of COVID-19 patients admitted to Dr. Cipto Mangunkusumo Hospital, Jakarta, Indonesia, from March to October 2020. Results During the study period, 490 patients were admitted and diagnosed with suspected and probable COVID-19. Of these patients, 50 (10.2%) were confirmed to have COVID-19, of which 20 (40%) patients with positive tests for SARS-CoV-2 had a fatal outcome. The fatality was higher in patients ≥10 years old, categorized with severe disease upon admission, with PaO 2 /FiO 2 ratios of ≤300 mmHg and chronic underlying diseases. The most common clinical manifestations were generalized symptoms, while acute respiratory distress syndrome (8/20) and septic shock (7/20) were the two most common causes of death. Increased procalcitonin, D-dimer, lactate dehydrogenase, and presepsin levels were found in all fatal COVID-19 cases. One patient met the criteria of multisystem inflammatory syndrome in children (MIS-C). Conclusion Our work highlights the high mortality rate in pediatric patients positive for the COVID-19 test. Further studies are needed to understand better the role of SARS-CoV-2 in elaborating the mechanisms leading to death in children with comorbidities.

Background: Indonesia has a high number of COVID-19 cases and mortalities relative to not only among the Asia Pacific region but the world. Children were thought to be less affected by the virus compared to adults. Most of the public data reported combined data between adults and children. The Indonesian Pediatric Society (IPS) was involved in the COVID-19 response, especially in the area of child health. One of IPS's activities is collecting data registries from each of their chapters to provide a better understanding of COVID-19 in children.Objective: The objective of this study was to share the data of suspected and confirmed COVID-19 cases in children from IPS's COVID-19 data registry.Method: This is a retrospective study from the IPS's COVID-19 registry data. We collected the data of COVID-19 in children during March to December 2020 from each of the IPS chapters. We analyzed the prevalence, case fatality rate (CFR), age groups, diagnosis, and comorbidities of the children diagnosed with COVID-19.Result: As of December 21, 2020, there were 35,506 suspected cases of children with COVID-19. In total, there were 522 deaths, with a case fatality ratio (CFR) of 1.4. There were 37,706 confirmed cases with 175 fatalities (CFR 0.46). The highest mortality in confirmed COVID-19 cases was from children ages 10–18 years (42 out of 159 cases: 26%). The most common comorbidity and diagnosis found were malignancy (17.3%) and respiratory failure (54.5%).Conclusion: The CFR of confirmed COVID-19 cases in children in Indonesia is high and should be a major public concern.
