“…Seroprevalence found in this study was of 16.6% (95%CI 15.4–17.8), while in the study by Pinto Junior et al 16 seroprevalence in schoolchildren was of 28.0%, with sample collection carried out in November and early December 2020 using the Leccurate SARS-CoV-2 Antibody Rapid Test Kit (Colloidal Gold Immunochromatography) in a distal tip sample in the city of Fortaleza. In the household survey carried out in England and Wales, in which a cohort of children was observed weekly through online interviews, seroprevalence ranged from 9.8 % to 13.0% according to age group 17 .…”

OBJETIVO: Estimar a soroprevalência de anticorpos do vírus SARS-CoV-2 em escolares de quatro a 14 anos de idade residentes no município de São Paulo, segundo variáveis clínicas, demográficas, epidemiológicas e sociais, durante o período de fechamento das escolas como medida de controle da covid-19. MÉTODOS: Realizou-se um inquérito sorológico em setembro de 2020 com amostra aleatória estratificada por tipo de rede de ensino (pública municipal, pública estadual e privada). Foi coletada amostra de sangue venoso utilizando-se o teste de imunoensaio de fluxo lateral da fabricante Wondfo para detecção de anticorpos totais contra o vírus SARS-CoV-2. Aplicaram-se questionários semiestruturados para o levantamento de dados clínicos, demográficos, sociais e epidemiológicos. RESULTADOS: A soroprevalência de anticorpos do vírus SARS-CoV-2 em escolares foi de 16,6% (IC95% 15,4–17,8). O estudo encontrou soroprevalências mais elevadas na rede pública municipal (18,5%; IC95% 16,6–20,6) e estadual (16,2%; IC95% 14,4–18,2) em relação à rede privada (11,7; IC95% 10,0–13,7) e entre escolares da raça/cor preta e parda (18,4%; IC95% 16,8–20,2) e no estrato social mais vulnerável (18,5%; IC95% 16,9–20,2). A pesquisa identificou menores soroprevalências nos escolares que relataram seguir as medidas recomendadas de proteção contra a covid-19. CONCLUSÃO: A soroprevalência de anticorpos contra o vírus SARS-CoV-2 atinge principalmente os escolares socialmente mais vulneráveis. Este estudo pode contribuir para embasar políticas públicas que reforcem a importância da suspensão das aulas presenciais e da necessidade de estratégias de medidas de proteção e acompanhamento do status sorológico daqueles que ainda não foram contemplados no calendário vacinal.

“…In a Brazilian study, it was reported that 73.7 and 52.9% of children and adults were asymptomatic, respectively. 13 However in this study, 34% of patients with PCR-positive results were asymptomatic. The results may be different, as patients who were COVID-19 antibody-positive and had late-stage complaints were included in this study.…”

Objective Symptoms due to coronavirus disease 2019 (COVID-19) may persist or new symptoms may appear later. It was aimed to investigate the relationships between late respiratory system findings, allergen sensitivity, and laboratory findings in children with asymptomatic or symptomatic COVID-19 history. Methods The study was conducted in tertiary hospital prospectively between April and July 2021. Children with respiratory system symptoms lasting longer than 1 month, with a history of asymptomatic or symptomatic COVID-19 infection and those who were anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)- antibody-positive were included. Late respiratory system findings, allergen sensitivity, and immunological and hematological findings were evaluated. Children with chronic diseases and those who were anti-SARS-CoV-2 antibody-negative were excluded. Results Of 105 patients, 44.8% were female with a mean age of 10.7 (1–17) years. Median time from history or exposure to COVID-19 was 5 months in all patients. Post-COVID-19 respiratory symptoms were cough (61%), followed by shortness of breath (46.7%), and chest pain (21%), which were similar between symptomatic and asymptomatic patients (p > 0.05). Of the laboratory findings, only the hemoglobin value was significantly higher in symptomatic patients than in asymptomatic patients (p = 0.03), and there was no difference between them in terms of other parameters. Conclusion It was shown that respiratory system symptoms may occur in the late period after COVID-19. The atopic status and laboratory findings of the patients did not affect this result.

“…This finding is in line with an earlier report, where adolescents displayed a higher prevalence than children (13.9% and 7.3%, respectively). 23 The lower rate of SARS-CoV-2 antibodies among younger children may be because they commonly experience recurrent episodes of seasonal viral infection, which may have primed their systems to develop strong immunity. 25 …”

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.
