Comparing Chinese children and adults with RT-PCR positive COVID-19: A systematic review

Clinical and Epidemiological Presentation of COVID-19 among Children in Conflict Setting

Background: This study aims to describe the observable symptoms of children with COVID-19 infection and analyze access to real-time polymerase chain reaction (RT-PCR) testing among children seeking care in Yemen. Method: In the period of March 2020−February 2022, data were obtained from 495 children suspected to have been infected with COVID-19 (from a larger register of 5634 patients) from the Diseases Surveillance and Infection Control Department at the Ministry of Public Health and Population in Aden, Yemen. Results: Overall, 21.4% of the children with confirmed COVID-19 infection were asymptomatic. Fever (71.4%) and cough (67.1%) were the most frequently reported symptoms among children, and children were less likely to have fever (p < 0.001), sore throat (p < 0.001) and cough (p < 0.001) compared to adults. A lower frequency of COVID-19-associated symptoms was reported among children with positive RT-PCR tests compared to children with negative tests. A lower rate of testing was conducted among children (25%) compared to adults (61%). Fewer tests were carried out among children <5 years (11%) compared to other age groups (p < 0.001), for children from other nationalities (4%) compared to Yemeni children (p < 0.001) and for girls (21%) compared to boys (30%) (p < 0.031). Conclusion: Understanding and addressing the cause of these disparities and improving guidelines for COVID-19 screening among children will improve access to care and control of the COVID-19 pandemic.

A Comprehensive Comparison of COVID-19 Characteristics (Wuhan‎ Strain) Between Children and Adults During Initial Pandemic Phase: A Meta-Analysis Study

Objectives: This systematic review and meta-analysis aimed to compare coronavirus disease 2019 (COVID-19) (Wuhan strain) features in children and adults during the initial pandemic phase. Methods: Until June 4, 2020, a systematic search was conducted on the EMBASE, PubMed, Web of Science, Google Scholar, and Scopus to find and collect studies based on available data among adults and children. The heterogeneity of the studies was assessed using I2 statistics and chi-square testing. The random-effect model was used to pool the effect sizes due to inter-study heterogeneity (chi-square P-value 0.1 and I2 >50%). Results: Fever (65.73%), cough (53.78%), expectoration (37.9%), gastrointestinal symptoms (37.01%), headache (23.41%), shortness of breath (21.65%), and myalgia (20.79%) were the most common symptoms reported in children, according to the pooled estimation analysis. Arthralgia (Effect estimate (ES): adults = 2.15, children = 17.94) and headache (ES: adults = 9.22, children = 23.41) were significantly observed higher in children (P-value = 0.019). Adult patients had a higher rate of abnormal computer tomography (CT)-scan findings, while most children had a normal study. Adults had significantly higher rates of comorbidities, whereas children had significantly higher rates of asthma (ES: 17.94% vs 8.85%; P-value = 0.026) and malignancy (‎ES: 10.36‎% vs ‎5.47‎‎%; P-value = 0.045‎). During initial pandemic phase, hydroxychloroquine (ES: 66.21% vs ‎‎29.01%; P-value = 0.001) and antibiotics (ES: 77.86% vs 38.01%; P-value = 0.001) ‎were used much more frequently in adult patients. Adults used much more antibiotics than children. Nonetheless, antibiotics were given to around 40% of the children studied. ‎ Conclusions: Although children were afflicted less than adults in the early stages of the pandemic and had lower mortality, clinical and radiological findings, as well as prognostic factors, did not differ significantly between adults and children. However, with the advent of novel variants, clinical signs and symptoms, complications, and outcomes changed in children significantly.

Pediatric Coronavirus Disease 2019: Clinical Features and Management

There is a lack of clarity regarding management of COVID-19 infection in children. This review aims to summarize the key clinical presentations and management of Pediatric COVID-19. The Medline database was searched for seminal articles and guidelines on COVID-19 presentation and management in children less than 18 years of age. COVID-19 has a lower incidence (1-5% of reported cases worldwide), causes milder disease with lower need for intensive care admission and lower mortality rate (0-0.7%) in children compared with adults. Multisystem inflammatory syndrome is a rare but severe complication in children. Majority of patients require supportive care including adequate hydration, nutrition and antipyretics. Supplemental oxygen therapy should be given in moderate to severe cases with all precautions to prevent air-borne COVID-19 spread. Steroids may be helpful in severe cases. Anticoagulation is indicated in moderate to severe cases with risk factors. More data on the efficacy and safety of antivirals and immunomodulators in children is needed.

COVID-19 in Children: Respiratory Involvement and Some Differences With the Adults

The coronavirus disease 2019 (COVID-19) represents a health problem with multidimensional impacts and heterogeneous respiratory involvement in children, probably due to the interaction between different and complex mechanisms that could explain its variable degrees of severity. Although the majority of reports reveal that children develop less severe cases, the number of patients is increasing with more morbidity. Most serious respiratory manifestations are acute respiratory distress syndrome (ARDS) and pneumonia. By understanding the key aspects that can be used to differentiate between pediatric and adult respiratory compromise by COVID-19, we can improve our knowledge, and thus decrease the negative impact of the disease in the pediatric population. In this mini review, we summarize some of the mechanisms and findings that distinguish between adult and pediatric COVID-19 and respiratory involvement, taking into account some issues related to the physiopathology, diagnosis, clinical and paraclinical presentation, severity, treatment, and control of the disease.

Systematic review of reviews of symptoms and signs of COVID-19 in children and adolescents

OBJECTIVE

To undertake a systematic review of reviews of the prevalence of symptoms and signs of COVID-19 in those aged under 20 years.

DESIGN

Narrative systematic review of reviews. PubMed, medRxiv, Europe PMC and COVID-19 Living Evidence Database were searched on 9 October 2020.

SETTING

All settings, including hospitalised and community settings.

PATIENTS

Children and young people (CYP) under age 20 years with laboratory-proven COVID-19.

STUDY REVIEW, DATA EXTRACTION AND QUALITY

Potentially eligible articles were reviewed on title and abstract by one reviewer. Quality was assessed using the modified AMSTARS criteria and data were extracted from included studies by two reviewers.

MAIN OUTCOME MEASURES

Prevalence of symptoms and signs of COVID-19.

RESULTS

1325 studies were identified and 18 reviews were included. Eight were high quality, 7 medium and 3 low quality. All reviews were dominated by studies of hospitalised children. The proportion of asymptomatic CYP ranged from 14.6% to 42%. Fever and cough were the the most common symptoms; proportions with fever ranged from 46% to 64.2% and with cough from 32% to 55.9%. All other symptoms or signs including rhinorrhoea, sore throat, headache, fatigue/myalgia and gastrointestinal symptoms including diarrhoea and vomiting were infrequent, occurring in less than 10%-20%.

CONCLUSIONS

Fever and cough are the most common symptoms in CYP with COVID-19, with other symptoms infrequent. Further research on symptoms in community samples are needed to inform pragmatic identification and testing programmes for CYP.
