Association between early initiation of breastfeeding and reduced risk of respiratory infection: implications for nonseparation of infant and mother in the COVID-19 context

Bindi Borg; Karleen Gribble; Karan Courtney-Haag (et al.)

Published: February 2022   Journal: Maternal & child nutrition
Early initiation of breastfeeding, within 1 h of birth, is vital for the health of newborns and reduces morbidity and mortality. Secondary analysis of the 2016 Nepal Demographic and Health Survey (DHS) showed that early initiation of breastfeeding significantly reduced the risk of acute respiratory infection (ARI) in children under 2 years. Early initiation of breastfeeding requires maternal proximity. Separation of infant and mother inhibits early initiation of breastfeeding and increases the risk that infants will suffer from ARIs. However, during the COVID-19 pandemic, guidance varied, with some recommending that infants and mothers with SARS-CoV-2 be isolated from one another. Nepal's Ministry of Health and Population recommended nonseparation, but the adherence to this guidance was inconsistent. Maternal proximity, nonseparation and early initiation of breastfeeding should be promoted in all birthing facilities.
Characteristics, outcomes, and severity risk factors associated with SARS-CoV-2 infection among children in the US national COVID cohort collaborative

Blake Martin; Peter E. DeWitt; Seth Russell (et al.)

Published: February 2022   Journal: JAMA Network Open

Understanding of SARS-CoV-2 infection in US children has been limited by the lack of large, multicenter studies with granular data. This study aims to examine the characteristics, changes over time, outcomes, and severity risk factors of children with SARS-CoV-2 within the National COVID Cohort Collaborative (N3C). It is a prospective cohort study of encounters with end dates before September 24, 2021, was conducted at 56 N3C facilities throughout the US. Participants included children younger than 19 years at initial SARS-CoV-2 testing.

Prenatal and neonatal complications of COVID-19: a systematic review

Zahra Pashaei; SeyedAhmad SeyedAlinaghi; Kowsar Qaderi (et al.)

Published: February 2022   Journal: Health Science Reports
The outbreak of coronavirus disease 2019 (COVID-19) over the past year has affected public health worldwide. During pregnancy, the maternal immune system and inflammatory responses are widely suppressed. Pregnancy-related immune system suppression could make the mother vulnerable to infectious diseases like SARS-COV-2. However, current data suggest little to no possibility of COVID-19 transmission in pregnant women to the fetus during pregnancy or childbirth. This systematic review focused on the possible complications of COVID-19 infection in the fetus and newborn babies including the possibility and evidence of vertical transmission by reviewing articles published during the first year of the COVID-19 pandemic.

Mohammed Yesuf; Mehd Abdu

Published: January 2022   Journal: Plos One

As of February 2021 COVID-19 report in 57 African countries, there were 3,761,512 confirmed cases and 98,088 deaths. Ethiopia reported the highest number of cases in East Africa with a total of 147,092 cases and 2,194 deaths. Over 1.5 billion students from 195 countries across the world separated from school as a consequence of the closure of schools related to the pandemic. This study aimed to determine the level of knowledge, attitude, prevention practices, and determinant factors regarding COVID-19 among preparatory school students in southwest Ethiopia. An institution-based cross-sectional study design was used for 422 samples. Each respondent was selected using simple random sampling. Data were collected using a self-administered questionnaire. The collected data were entered and analyzed using Statistical Package for social science software version 25.0. Multivariable binary logistic regression was used to identify factors that were significantly associated with the practice of COVID-19 prevention.

Diffusion of COVID-19 among children and adolescents during the second and third waves of the pandemic in Italy

Francesca Bassi; Mattia Doria

Published: January 2022   Journal: European Journal of Pediatrics
This paper explores COVID-19 diffusion among children and adolescents (up to 19 years old) in Italy using the publicly available data that were collected and released by the Italian National Institute of Health (ISS). It considers in more detail the so-called second and third waves of the pandemic in Italy and explores the relationship between schools opening and the diffusion of COVID-19, which is a highly debated topic in the recent reference literature. It analyses the dynamics of COVID-19 incidence in the country as a whole and in its individual regions. Moreover, it compares the regions in which different levels of restrictions were imposed during the pandemic as well as different school closure calendars.
COVID-19 and pregnancy

Sonja A. Rasmussen; Denise J. Jamieson

Published: January 2022   Journal: Infectious Disease Clinics of North America
Since the emergence of SARS-CoV-2 in late 2019, the virus and the response to it have had catastrophic effects on the world’s health, societies, and economies. Early on, data on the effects of SARS-CoV-2 on the pregnant person and fetus were limited. Data on the effects during pregnancy of previous coronaviruses (severe acute respiratory syndrome [SARS] and Middle East respiratory syndrome [MERS]) are sparse, but those data along with information on other respiratory infections such as influenza raised concerns about the potential effects of COVID-19 during pregnancy.This study reviews available information on the effects of SARS-CoV-2 infection during pregnancy and on the effectiveness and safety of the SARS-CoV-2 vaccines in protecting pregnant persons and their newborns from COVID-19.
COVID-19 testing among US children, parental preferences for testing venues, and acceptability of school-based testing

Chloe A. Teasdale; Luisa N. Borrell; Yanhan Shen (et al.)

Published: January 2022   Journal: Public health reports

Testing remains critical for identifying pediatric cases of COVID-19 and as a public health intervention to contain infections. This study surveyed US parents to measure the proportion of children tested for COVID-19 since the start of the pandemic, preferred testing venues for children, and acceptability of school-based COVID-19 testing. It conducted an online survey of 2074 US parents of children aged ≤12 years in March 2021. It applied survey weights to generate national estimates, and it used Rao-Scott adjusted Pearson χ2 tests to compare incidence by selected sociodemographic characteristics. It used Poisson regression models with robust SEs to estimate adjusted risk ratios (aRRs) of pediatric testing.

Published: January 2022   Journal: Biochemistry and Molecular Biology Education
Facing recent threats of coronavirus disease (COVID-19), an educational strategy was designed and applied to middle school students in order to reinforce related knowledge and behaviors. A group of 65 middle school students (14–18 years old) developed several designed online curricular activities. After the intervention, students answered a questionnaire to assess if they: (a) were familiar with the terms COVID 19 and SARS-CoV-2; (b) were conscious about the importance of preventive measures to stop the spread of this disease; (c) were engaged in these activities; (d) were motivated to research on health-related issues. This study was a first to attempt to evaluate student's perceptions about SARS-CoV-2 infection and support education regarding COVID-19, mainly on the reinforcement of preventive measures.

Published: January 2022   Journal: International journal of infectious diseases

The aim of this study was to estimate the impact of the COVID-19 pandemic on the circulation of non-SARS-CoV-2 respiratory viruses and clinical characteristics of COVID-19 in hospitalized children. 226 and 864 children admitted to Children's City Clinical Hospital with acute respiratory infection in September-November of 2018 and 2020 in Moscow were tested for respiratory viruses using multiplex PCR and Mycoplasma pneumoniae/Chlamydia pneumoniae using ELISA.

Stress, dependence, and COVID-19–related changes in past 30-day marijuana, electronic cigarette, and cigarette use among youth and young adults

Stephanie L. Clendennen; Kathleen R. Case; Aslesha Sumbe (et al.)

Published: December 2021   Journal: Tobacco Use Insights

Studies show smoking and vaping behaviors increase risk of contracting and worse symptoms of COVID-19. This study examines whether past 30-day youth and young adult users of marijuana, e-cigarettes, and cigarettes self-reported changes in their use of these substances due to the COVID-19 pandemic; and cross-sectional associations between perceived stress, nicotine or marijuana dependence, and COVID-19–related changes in use. Participants were 709 past 30-day self-reported substance users from the Texas Adolescent Tobacco and Marketing Surveillance study (TATAMS; mean age = 19; 58% female; 38% Hispanic, 35% white). Multiple logistic regression models assessed cross-sectional associations between perceived stress and dependence and increased, decreased, or sustained past 30-day use of marijuana, e-cigarettes, and cigarettes due to COVID-19 (e.g., “Has your marijuana use changed due to the COVID-19 outbreak?”). Covariates included age, race/ethnicity, socio-economic status (SES), dependence (exposure: stress), and stress (exposure: dependence).

Transmission of SARS-CoV-2 by children and young people in households and schools: a meta-analysis of population-based and contact-tracing studies

Russell Viner; Claire Waddington; Oliver Mytton (et al.)

Published: December 2021   Journal: Journal of Infection
The role of children and young people (CYP) in transmission of SARS-CoV-2 in household and educational settings remains unclear. This study undertook a systematic review and meta-analysis of contact-tracing and population-based studies at low risk of bias. It searched 4 electronic databases on 28 July 2021 for contact-tracing studies and population-based studies informative about transmission of SARS-CoV-2 from 0-19 year olds in household or educational settings. It excluded studies at high risk of bias, including from under-ascertainment of asymptomatic infections. It undertook multilevel random effects meta-analyses of secondary attack rates (SAR: contact-tracing studies) and school infection prevalence, and used meta-regression to examine the impact of community SARS-CoV-2 incidence on school infection prevalence.

Jun Yi Sim; Ping-Sheng Wu; Ching-Feng Cheng (et al.)

Published: December 2021   Journal: Journal of Microbiology, Immunology and Infection

Characteristics of children with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in Taiwanese households is nascent. This study sought to characterize SARS-CoV-2 infection, and estimate the relative risk of infection among children within households during school closures in Taipei and New Taipei City. It reviewed consecutive children below 18 years presenting to our emergency department from May 18, 2021 to July 12, 2021 who underwent real-time reverse-transcription polymerase chain reaction (rRT-PCR) for SARS-CoV-2 from respiratory swabs. Demographics, symptoms, and contacts were captured from medical records. Household contact was defined as an individual with confirmed COVID-19 living in the same residence as the child.

Weighing policymaking: a narrative review of school closures as Covid-19 pandemic-mitigation strategies

Raffaella Nenna; Hana Zeric; Laura Petrarca (et al.)

Published: December 2021   Journal: Pediatric Pulmonology

In the era of data-driven decision-making, unacceptable haziness, and inconsistency surrounds the yearlong scientific and public debate on the school closure policy in the coronavirus disease-2019 (COVID-19) pandemic mitigation efforts. The present literature review stems out of the need for a clear scaffold collecting in one place all current evidence, as well as helping to organize incoming future evidence, concerning both the role of schools in driving the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) community spread and the cost-effectiveness of school closure in containing such spread. References for this review were initially identified through searches of PubMed, Scopus, and Cochrane Library for articles published from March 2020 to March 2021 by the use of key terms “Schools,” “COVID-19,” “pandemic,” “clusters,” “outbreak,” and “seroprevalence,” selecting all articles from 2020 to 2021 with full-text availability. A further search was undertaken by screening citations of articles found in the original search and through Google Scholar and ResearchGate.

SARS-CoV-2 infection among school population of one developing country: do school closures protect students and teachers against SARS-CoV-2 infection?

Carol Bibiana Colonia; Rosanna Camerano-Ruiz; Andrés Felipe Mora-Salamanca (et al.)

Published: December 2021   Journal: International Journal of Environmental Research and Public Health
Evidence about the effectiveness of school closures as a measure to control the spread of COVID-19 is controversial. This study posit that schools are not an important source of transmission; thus, it analyzed two surveillance methods: a web-based questionnaire and a telephone survey that monitored the impact of the pandemic due to COVID-19 cases in Bogotá, Colombia. It estimated the cumulative incidences for Acute Respiratory Infection (ARI) and COVID-19 for each population group. Then, it assessed the differences using the cumulative incidence ratio (CIR) and 95% confidence intervals (CI95%)
