The epidemiology and characteristics of SARS-CoV-2 in the hospitalized Mozambican pediatric population are scarce. We aimed to assess the burden of COVID-19 in the pediatric population at Hospital Central de Maputo and identify comorbidities and factors associated with death among hospitalized COVID-19 cases. A cross-sectional study was conducted from October 2020 to October 2022. Available records were retrieved from admission books. Univariate and bivariate analyses were reported to describe the sample characteristics. The frequency of pediatric cases admitted with COVID-19 was 0.6% (95% confidence interval (CI): 0.5–0.6; 364/63,753), and the frequency of pediatric cases hospitalized with COVID-19 was 2.5% (95% CI: 2.2–2.9; 173/6807). The monthly frequency of pediatric cases admitted and hospitalized with COVID-19 ranged from 0.1% to 5.4% and from 0.2% to 42.1%, respectively. In children hospitalized with COVID-19, underweight was the most observed comorbidity (17.4%; 19/109); death was observed in 30% (95% CI: 22.2–39.1; 33/110), and it was significantly higher in underweight children than in non-underweight children (61.5% [8/13] vs. 21.3% [16/75]; p-value = 0.005). Given the heightened risk of mortality among undernourished children compared to non-undernourished children, vaccination for COVID-19 should be prioritized for undernourished children.

The World Health Organization’s systems framework shows that service delivery is key to addressing pressing health needs. Inadequate healthcare and the lack of healthcare services are factors associated with undernutrition and diarrhea in children under five, two health conditions with high morbi-mortality rates in Mozambique. The aim of the analysis was to determine the readiness score of nutrition and diarrhea services for children under five and the influence of malaria and HIV (Human Immunodeficiency Virus) service readiness on the readiness of these two services. A total of 1644 public health facilities in Mozambique were included from the 2018 Service Availability and Readiness Assessment. Additionally, a cross-sectional study was conducted to determine the availability and readiness scores of nutrition services in 2021 in five referral health facilities. The availability of nutrition and diarrhea services for children is low in Mozambique, with both scoring below 75%. Major unavailability was observed for human resources, guidelines, and training dimensions. Diarrhea (median (IQ): 72.2% (66.7 to 83.3)) and nutrition service readiness (median (IQ): 57.1% (52.4 to 57.1)) scores were significantly different (p < 0.001), while it is desirable for both services to be comprehensively ready. Nutrition services are positively associated with diarrhea service readiness and both services are associated with malaria and HIV service readiness (p < 0.05). None of the health facilities had all tracer items available and none of the facilities were considered ready (100%). There is a persisting need to invest comprehensively in readiness dimensions, within and across child health services.
