Saliva: an important alternative for screening and monitoring of COVID-19 in children

Catielma Nascimento Santos; Karla Mayra Rezende; Nilson Ferreira de Oliveira Neto (et al.)

Published: November 2020   Journal: Brazilian Oral Research
The increasing number of cases of COVID-19 worldwide poses challenges to healthcare systems not only in effectively identifying individuals positive for SARS-CoV-2, but also in isolating cases to minimise contagion in early diagnosing more severe cases that will need hospitalization. Less-invasive collection methods are indispensable in a pandemic scenario as large-scale tests are necessary to understand the actual evolution of contagion in different populations, thus enabling decision-making based on scientific evidence. Saliva has been shown to be an alternative for diagnosing viral infections as this biological fluid can be easily and quickly collected without using specific devices and causing less discomfort during collection, which is an important factor for use in children. Despite the smaller percentage of severe cases of COVID-19 among children, they seem to play an important role in the contagion as they have the same potential of transmission as that of adults. Knowing the evolution of COVID-19 pandemic in children is extremely important, mainly regarding the changing in rules of social distancing, such as re-opening schools and recreational activities spaces.
Coronaviruses in children: a review of potential mechanisms of childhood protection

Firas A. Rabi; Mazhar S. Al Zoubi; Montaha Mohammed Al‐Iede (et al.)

Published: November 2020   Journal: Acta Paediatrica
The 2019 coronavirus disease (COVID‐19) has spread worldwide and the number of cases continues to rise exponentially. Epidemiologic reports indicate that severity of illness increases with age. However, the reasons behind the relative protection of children and infants are unclear. Whether the rationale is host‐related or virus‐dependent is important to determine since the latter could change with viral mutations. This survey reviewed factors that could affect the susceptibility of children to the novel coronavirus.
Baseline characteristics, management, and outcomes of 55,270 children and adolescents diagnosed with COVID-19 and 1,952,693 with influenza in France, Germany, Spain, South Korea and the United States: an international network cohort study

Talita Duarte-Salles; David Vizcaya; Andrea Pistillo (et al.)

Published: November 2020   Journal: Physical Therapy
This study comprehensively characterizes a large international cohort of pediatric COVID-19 patients, and almost 2 million with previous seasonal influenza across 5 countries. Although uncommon, pneumonia, acute respiratory distress syndrome (ARDS) and multisystem inflammatory syndrome (MIS-C) were more frequent in children and adolescents diagnosed with COVID-19 than in those with seasonal influenza. Dyspnea, bronchiolitis, anosmia and gastrointestinal symptoms were more frequent in COVID-19, and could help to differentiate pediatric COVID-19 from influenza. A plethora of medications were used during the management of COVID-19 in children and adolescents, with great heterogeneity in the use of antiviral therapies as well as of adjunctive therapies.

Immune responses to SARS-CoV-2 in three children of parents with symptomatic COVID-19

Shidan Tosif; Melanie R. Neeland; Nigel W. Crawford (et al.)

Published: November 2020   Journal: Nature Communications
Compared to adults, children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have predominantly mild or asymptomatic infections, but the underlying immunological differences remain unclear. This study describes clinical features, virology, longitudinal cellular, and cytokine immune profile, SARS-CoV-2-specific serology and salivary antibody responses in a family of two parents with PCR-confirmed symptomatic SARS-CoV-2 infection and their three children, who tested repeatedly SARS-CoV-2 PCR negative. Cellular immune profiles and cytokine responses of all children are similar to their parents at all timepoints. All family members have salivary anti-SARS-CoV-2 antibodies detected, predominantly IgA, that coincide with symptom resolution in 3 of 4 symptomatic members. Plasma from both parents and one child have IgG antibody against the S1 protein and virus-neutralizing activity detected. Using a systems serology approach, this study shows higher levels of SARS-CoV-2-specific antibody features of these family members compared to healthy controls. These data indicate that children can mount an immune response to SARS-CoV-2 without virological confirmation of infection, raising the possibility that immunity in children can prevent the establishment of SARS-CoV-2 infection.

Who should be prioritized for COVID-19 vaccination?

Fiona M. Russell; Brian Greenwood

Published: November 2020   Journal: Human Vaccines & Immunotherapeutics
The development of COVID-19 vaccines is occurring at a rapid pace, with the potential for a vaccine to be available within 6 months. So who should be prioritized for vaccination when in the first instance, there will be insufficient supply to meet demand? There is no doubt that health-care workers in all settings should be vaccinated first, but who comes next will be a complex decision based on local epidemiology, societal values, and the ability of the vaccines to prevent both severe disease and to reduce transmission thereby eliciting herd protection. The decision on who to vaccinate should be equitable, highly contextualized, and based on the property of each vaccine. In some settings, the elderly may be prioritized, in others, it may be the population most likely to get infected and responsible for community spread. To support decision-making on who to be prioritized for vaccination requires urgent additional research on the epidemiology of COVID-19; preexisting immunity and who is responsible for transmission in a variety of settings; the safety, immunogenicity, and efficacy of COVID-19 vaccines in children and pregnant women; and determining whether COVID-19 vaccines prevent asymptomatic infection and transmission.
Parents’ and guardians’ views on the acceptability of a future COVID-19 vaccine: a multi-methods study in England

Sadie Bell; Richard Clarke; Sandra Mounier-Jack (et al.)

Published: November 2020   Journal: Vaccine

The availability of a COVID-19 vaccine has been heralded as key to controlling the COVID-19 pandemic. COVID-19 vaccination programme success will rely on public willingness to be vaccinated. This study uses a multi-methods approach - involving an online cross-sectional survey and semi-structured interviews - to investigate parents’ and guardians’ views on the acceptability of a future COVID-19 vaccine.

A study of breastfeeding practices, SARS-CoV-2 and its antibodies in the breast milk of mothers confirmed with COVID-19

Sicong Peng; Huaping Zhu; Lixia Yang (et al.)

Published: November 2020   Journal: The Lancet Regional Health - Western Pacific
The possibility of 2019 novel coronavirus disease transmission to neonates through breast milk remains unverified. This paper presents the interim results of a longitudinal study being carried out in Hubei province. As of 1 April 2020, 24 mothers confirmed with COVID-19, 19 mothers suspected with COVID-19 but Polymerase chain reaction negative, and 21 mothers without COVID-19 and their neonates have been recruited. Telephone follow-up was conducted to collect information on breastfeeding practices. Forty-four breast milk samples were collected from 16 of the 24 mothers with confirmed COVID-19 for the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) ribonucleic acid (RNA) and antibodies (IgM and IgG) testing.
Possible vertical transmission and antibodies against SARS‐CoV‐2 among infants born to mothers with COVID‐19: a living systematic review

George M. Bwire; Belinda J. Njiro; Dorkasi L. Mwakawanga (et al.)

Published: October 2020   Journal: Journal of Medical Virology
Current evidence suggests that coronavirus disease 2019 (COVID‐19), caused by severe respiratory syndrome coronavirus 2 (SARS‐CoV‐2), is predominantly transmitted from human‐to‐human. However, evidence on vertical transmission and natural passive immunity among the newborns exposed to COVID‐19 is scanty and varies. This poses a challenge on preventive interventions for the newborns. A systematic review was conducted to first, determine the likelihood of vertical transmission among COVID‐19 exposed infants and second, determine whether antibodies against SARS‐CoV‐2 were generated among COVID‐19 vertically exposed but negative infants. This review registered in PROSPERO searched evidence from PubMed/MEDLINE and Google Scholar, among others.
Public health antibody screening indicates a six-fold higher SARS-CoV-2 exposure rate than reported cases in children

Markus Hippich; Lisa Holthaus; Robin Assfalg (et al.)

Published: October 2020   Journal: Clinical Advances
This paper describes a highly specific and sensitive approach to measuring antibodies against SARS-CoV-2 for population-scale immune surveillance. Antibody positivity was defined as a dual-positive response against both the receptor-binding domain and nucleocapsid proteins of SARS-CoV-2. Antibodies were measured by immunoprecipitation assays in capillary blood from 15,771 children aged 1 to 18 years living in Bavaria, Germany, and participating in a public health type 1 diabetes screening program, in 1,916 dried blood spots from neonates in a Bavarian screening study, and in 75 SARS-CoV-2-positive individuals. Virus positive incidence was obtained from the Bavarian health authority data.

The clinical course of SARS-CoV-2 positive neonates

Giuseppe De Bernardo; Maurizio Giordano; Giada Zollo (et al.)

Published: October 2020   Journal: Journal of Perinatology
The COVID-19 pneumonia was firstly reported in Wuhan, China, in December 2019. The disease had a rapid spread all over the word becoming an international public health emergency. Limited data were available on COVID-19 positive neonates. We reviewed relevant literature to understand the clinical course of disease and transmission routes in affected neonates. The aim of the study was evaluating the clinical course and prognosis of SARS-CoV-2 positive neonates. Based on current literature, the hypothesis of vertical transmission of SARS-CoV-2, though conceivable, remains unproven. A research conducted on PubMed database from December 2019 to April 27, 2020 revealed that were reported 25 neonates affected by SARS-CoV-2. Main symptoms were fever, cough, or shortness of breath but often these neonates did not show other symptoms during length stay in hospital. No deaths occurred.

Synthesis and systematic review of reported neonatal SARS-CoV-2 infections

Roberto Raschetti; Alexandre J. Vivanti ; Christelle Vauloup-Fellous (et al.)

Published: October 2020   Journal: Nature Communications
A number of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infections have been reported in neonates. This survey aims to clarify the transmission route, clinical features and outcomes of these infections. It presents a meta-analysis of 176 published cases of neonatal SARS-CoV-2 infections that were defined by at least one positive nasopharyngeal swab and/or the presence of specific IgM. This report shows that 70% and 30% of infections are due to environmental and vertical transmission, respectively.
Systematic analysis of infectious disease outcomes by age shows lowest severity in school-age children

Judith R. Glynn; Paul A. H. Moss

Published: October 2020   Journal: Scientific Data

The COVID-19 pandemic has ignited interest in age-specific manifestations of infection but surprisingly little is known about relative severity of infectious disease between the extremes of age. In a systematic analysis, this study identifies 142 datasets with information on severity of disease by age for 32 different infectious diseases, 19 viral and 13 bacterial. For almost all infections, school-age children have the least severe disease, and severity starts to rise long before old age. Indeed, for many infections even young adults have more severe disease than children, and dengue was the only infection that was most severe in school-age children. Together with data on vaccine response in children and young adults, the findings suggest peak immune function is reached around 5–14 years of age. Relative immune senescence may begin much earlier than assumed, before accelerating in older age groups. This has major implications for understanding resilience to infection, optimal vaccine scheduling, and appropriate health protection policies across the life course.

Pandemics, epidemics and inequities in routine childhood vaccination coverage: a rapid review

Nick Spencer; Rita Nathawad; Emmanuele Arpin (et al.)

Published: October 2020

Inequity in routine childhood vaccination coverage is well researched. Pandemics disrupt infrastructure and divert health resources from preventive care, including vaccination programmes, leading to increased vaccine preventable morbidity and mortality. COVID-19 control measures have resulted in coverage reductions. We conducted a rapid review of the impact of pandemics on existing inequities in routine vaccination coverage. PICO search framework: Population: children 0–18 years; Intervention/exposure: pandemic/epidemic; Comparison: inequality; Outcome: routine vaccination coverage. The review demonstrates a gap in the literature as none of the 29 papers selected for full-paper review from 1973 abstracts identified from searches met the inclusion criteria.

Age-structured model for COVID-19: Effectiveness of social distancing and contact reduction in Kenya

Mark Kimathi; Samuel Mwalili; Viona Ojiambo (et al.)

Published: October 2020   Journal: Infectious Disease Modelling
Coronavirus disease 2019 is caused by severe acute respiratory syndrome coronavirus 2. Kenya reported its first case on March 13, 2020 and by March 16, 2020 she instituted physical distancing strategies to reduce transmission and flatten the epidemic curve. An age-structured compartmental model was developed to assess the impact of the strategies on COVID-19 severity and burden. Contacts between different ages are incorporated via contact matrices. Simulation results show that 45% reduction in contacts for 60-days period resulted to 11.5–13% reduction of infections severity and deaths, while for the 190-days period yielded 18.8–22.7% reduction. The peak of infections in the 60-days mitigation was higher and happened about 2 months after the relaxation of mitigation as compared to that of the 190-days mitigation, which happened a month after mitigations were relaxed. Low numbers of cases in children under 15 years was attributed to high number of asymptomatic cases. High numbers of cases are reported in the 15–29 years and 30–59 years age bands. Two mitigation periods, considered in the study, resulted to reductions in severe and critical cases, attack rates, hospital and ICU bed demands, as well as deaths, with the 190-days period giving higher reductions.
