Investigation of severe acute respiratory syndrome coronavirus 2 antibodies among the paediatric population in Mogadishu, Somalia.

BACKGROUND

We undertook this cross-sectional study to determine the level of circulating anti-severe acute respiratory syndrome coronavirus 2 immunoglobulins (IgM and IgG) in children, as well as to evaluate other potential risk factors.

METHODS

Children attending the outpatient department of the SOS and Benadir Hospitals in Mogadishu from 26 July to 8 August 2021 were selected following parental consent. The children (aged <18 y) were screened using the coronavirus disease 2019 (COVID-19) rapid test lateral flow immune-assay kit.

RESULTS

Of the 500 children screened for COVID-19, 32 (6.4%) tested positive, out of which 26 (5.2%) had IgG antibodies, while five (1%) had IgM, with the other child (0.2%) having both circulating IgG and IgM antibodies. Also, 46.9% of the COVID-19-positive children were asymptomatic without any clinical signs of the disease. Children aged >6 y and those attending school were the most affected (p=0.002). The most common clinical features among positive children were fever (22.6%), cough (22.2%), shortness of breath (5.8%) and loss of smell (2.6%) and taste (2.2%). Similarly, not wearing a facemask as a preventive measure was found to be a significant risk factor (p=0.007).

CONCLUSIONS

This study shows that children are at risk of contracting COVID-19 infection. Our study also shows evidence of a high rate of IgG antibodies in school-aged children having close contact with infected adults, in those not wearing facemasks, as well as in those with a family history of comorbidities.
