Congenital infection (syphilis, aids, viral hepatitis and coronavirus) in pregnancy

Pregnancy may increase susceptibility to the infection diseases and associated increased mortality rates. In the present chapter, we wanted to discuss about clinical manifestations, laboratory diagnosis, management of the infection, prevention and prophylaxis of infections in pregnancy and perinatal period. We mainly focus on the congenital infections caused by the pathogens including human immunodeficiency virus (HIV), T. Pallidum, SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2) and viral hepatitis viruses (B, C, and E) that change maternal fetal out comes. © 2023 Nova Science Publishers, Inc.

Outcome of SARS-CoV-2 in pregnancy and newborns-is there a new kid in the TORCH block?

Objective. This study aimed to perform a systematic review of existing literature to assess the outcomes of pregnancy in women with COVID-19 infection and their newborns while estimating the possibility of vertical transmission. Materials and methods. We conducted a systematic literature research using Pubmed and Google Schol-ar covering the period from December 2019 to 20th of November 2020. The review was conducted in ac-cordance with PRISMA guidelines. Outcomes. We included 16 studies – systematic reviews and meta-analyses published between May 2020 and November 2020 – which focused on perinatal outcomes of pregnant women with COVID-19 and 7 case reports of neonates with congenital transmission of COVID-19. Overall, the rate of COVID-19 cases in neonates of COVID-19 positive mothers was 3% with 95% CI [1.86, 4.24]). The preterm birth rate was 16.4% with 95% CI [10.5, 22.3] and the rate of stillbirths and foetal deaths was 1.4% (11 studies, 0 to 4.8%). From the 7 newborns with proved vertical transmission, majority were born preterm, with good birth weight and APGAR score and heterogenous symptoms;4 developed severe symptoms. Overall progress and evolution for both mother and newborn was good. Conclusions. COVID-19 impact on pregnancy outcome is similar to general population in regard to preterm rate and stillbirth rate. Vertical transmission is possible and it seems to occur in about 3% of cases. Overall maternal and perinatal outcome is favourable and clinical presentation of in utero transmission of SARS-CoV-2 in newborns is heterogenous. © 2021, Amaltea Medical Publishing House.

Neurodevelopment in infants with antenatal or early neonatal exposure to SARS-CoV-2.

BACKGROUND: Antenatal and neonatal viral exposure may put the developing brain at risk for abnormal neurodevelopment. A clinical program at Children's National Hospital provides detailed follow-up of infants with in utero or neonatal SARS-CoV-2 exposure. AIMS: To determine impact of early SARS-CoV-2 exposure on neurodevelopment. STUDY DESIGN: We performed a prospective observational study of infant evaluations between 3/2020 and 11/2021. Demographics, pregnancy and birth details, SARS-CoV-2 data, specialty consultations, and NICU records were extracted from infants' medical records. Infants had neurologic exams and developmental screening with Ages and Stages Questionnaire (ASQ). Correlations between SARS-CoV-2 exposure type and neurodevelopmental outcomes were analyzed. SUBJECTS: Thirty-four infants evaluated in the SARS-CoV-2 follow-up program. OUTCOME MEASURES: Abnormal neurologic exams or ASQ scores near or below suggested cut-offs. RESULTS: Infants received up to three evaluations. Most (28/34; 82 %) were exposed in utero - 16 to symptomatic mothers (IU-S) and 12 to asymptomatic mothers (IU-A). Six were exposed only as a neonate. IU-S had abnormal neurologic exams at mean (SD) age 112 (24) days and ASQ scores near or below cut-offs for all domains more frequently than IU-A or neonatally exposed infants. IU-S were more likely to score below any ASQ cutoff compared to IU-A (P = .04); differences were significant for Fine Motor (P = .01) and Personal-Social (P = .02) domains. CONCLUSIONS: Early SARS-CoV-2 exposure may impact neurodevelopment, especially among infants exposed in utero to symptomatic gestational parents. Vaccination and other precautions to reduce early-in-life infection may protect against neurodevelopmental delays. Children with early SARS-CoV-2 exposure should have additional longitudinal screening for neurodevelopmental delays.

Congenital Infection of Severe Acute Respiratory Syndrome Coronavirus 2 With Intrauterine Fetal Death: A Clinicopathological Study With Molecular Analysis.

BACKGROUND: Observations of vertical transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection from mother to fetus have recently been described in the literature. However, the consequences of such transmission, whether fetal or neonatal, are poorly understood. METHODS: From a case of in utero fetal death at 24+2 weeks of gestation that occurred 7 days after the diagnosis of symptomatic SARS-CoV-2 infection in the mother, we isolated the incriminating virus by immunochemistry and molecular techniques in several fetal tissues, with a variant analysis of the SARS-CoV-2 genome. RESULTS: The fetal demise could be explained by the presence of placental histological lesions, such as histiocytic intervillositis and trophoblastic necrosis, in addition to fetal tissue damage. We observed mild fetal growth retardation and visceral damage to the liver, causing hepatocellular damage and hemosiderosis. To the best of our knowledge, this is the first report in the literature of fetal demise secondary to maternal-fetal transmission of SARSCoV- 2 with a congenital infection and a pathological description of placental and fetal tissue damage. CONCLUSIONS: SARS-CoV-2 was identified in both specimens using 3 independent techniques (immunochemistry, real-time quantitative polymerase chain reaction, and realtime digital polymerase chain reaction). Furthermore, the incriminating variant has been identified.

Toxoplasmosis in children during the COVID 19 pandemic

The aim is to study the features of toxoplasmosis during the COVID19 pandemic. Materials and methods. During the period 2019- 2021, 144 patients with an established diagnosis of toxoplasmosis were observed. 2 cases of congenital toxoplasmosis, 11 cases of acute acquired toxoplasmosis (in 2020-21) and 132 cases of chronic toxoplasmosis. Results. The concentration level of IgG antibodies to T.gondii in 2020-21 was higher than in 2019, and 4 children over 14 years old with chronic toxoplasmosis had a new COVID19 coronavirus infection 2 months before admission to the hospital and had the highest concentration of IgG antibodies to T.gondii. Conclusion. During the COVID19 pandemic, there is an increase in cases of acute acquired toxoplasmosis and in 7% of children over 14 years of age, reactivation of latent toxoplasmosis cannot be excluded, given the increased levels of IgG antibody concentrations compared to the pre-covid period. Apparently, an alternative interpretation to enzyme immunoassay is the immunoblot method (line-blot), since G antibodies to different parasite proteins are detected and it is possible to determine the phase of infection (reactivation or latent infection if the patient has only G antibodies). In the detection of an infectious syndrome (febrility. Lymphadenopathy, hepato or splenomegaly, chorioretinitis) it is necessary to make a differential diagnosis with herpesvirus infections that cause a similar clinical picture.

From Fetal to Neonatal Neuroimaging in TORCH Infections: A Pictorial Review.

Congenital infections represent a challenging and varied clinical scenario in which the brain is frequently involved. Therefore, fetal and neonatal neuro-imaging plays a pivotal role in reaching an accurate diagnosis and in predicting the clinical outcome. Congenital brain infections are characterized by various clinical manifestations, ranging from nearly asymptomatic diseases to syndromic disorders, often associated with severe neurological symptoms. Brain damage results from the complex interaction among the infectious agent, its specific cellular tropism, and the stage of development of the central nervous system at the time of the maternal infection. Therefore, neuroradiological findings vary widely and are the result of complex events. An early detection is essential to establishing a proper diagnosis and prognosis, and to guarantee an optimal and prompt therapeutic perinatal management. Recently, emerging infective agents (i.e., Zika virus and SARS-CoV2) have been related to possible pre- and perinatal brain damage, thus expanding the spectrum of congenital brain infections. The purpose of this pictorial review is to provide an overview of the current knowledge on fetal and neonatal brain neuroimaging patterns in congenital brain infections used in clinical practice.

Viral Infections During Pregnancy: The Big Challenge Threatening Maternal and Fetal Health.

Viral infections during pregnancy are associated with adverse pregnancy outcomes, including maternal and fetal mortality, pregnancy loss, premature labor, and congenital anomalies. Mammalian gestation encounters an immunological paradox wherein the placenta balances the tolerance of an allogeneic fetus with protection against pathogens. Viruses cannot easily transmit from mother to fetus due to physical and immunological barriers at the maternal-fetal interface posing a restricted threat to the fetus and newborns. Despite this, the unknown strategies utilized by certain viruses could weaken the placental barrier to trigger severe maternal and fetal health issues especially through vertical transmission, which was not fully understood until now. In this review, we summarize diverse aspects of the major viral infections relevant to pregnancy, including the characteristics of pathogenesis, related maternal-fetal complications, and the underlying molecular and cellular mechanisms of vertical transmission. We highlight the fundamental signatures of complex placental defense mechanisms, which will prepare us to fight the next emerging and re-emerging infectious disease in the pregnancy population.

Dew drops on newborn skin - congenital miliaria crystallina in the context of maternal SARS-CoV2 infection

Objectives: To report a rare case of extensive congenital miliaria crystallina. Results: A male infant was born at term by Caesarian section due to warning signs of fetal distress. The pregnancy had been uneventful. However, a maternal SARS-CoV2-infection occurred 2 days before birth. Immediately at birth, the newborn presented with a striking appearance of disseminated pinpoint-sized vesicles filled with clear fluid. Preemptive antibiotic treatment was initiated On dermatology consult, a diagnosis of congenital miliaria crystallina was made due to the typical clinical presentation. Investigations for congenital infections (Herpes, Varicella) were negative as well as repeat sampling for SARSCoV2. Antibiotic treatment was stopped. Treatment included reduction of ambient temperature/humidity and disinfectant dressings leading to a quick resolution of miliaria within 2-3 days. Clinical follow-up on DOL 20 revealed normal skin with areas of flaky desquamation. Discussion: Miliaria is a benign, transient disorder caused by occlusion and disruption of eccrine sweat ducts and occasionally occurs in infants. Congenital presentation of extensive miliaria crystallina however is exceptional with only sporadic reports in the medical literature. The role of SARS-CoV2 in our case remains unclear as fetal infection was excluded. However, a few cases of congenital miliaria were reported in the context of other maternal infections, suggesting a role of maternal fever and increased temperature of amniotic fluid in the pathogenesis of congenital miliaria. Clinicians should be aware of this striking yet harmless congenital presentation, which may mimic a congenital disorder of cornification or another severe skin disease, causing unnecessary anxiety.

Parvovirus (B19) Infection during Pregnancy: Possible Effect on the Course of Pregnancy and Rare Fetal Outcomes. A Case Report and Literature Review.

Infection caused by human parvovirus B19 (B19) often has mild yet wide-ranging clinical signs, with the course of disease usually defined as benign. Particularly prevalent in the population of young children, the virus is commonly transmitted to the parents, especially to susceptible mothers. During pregnancy, particularly the first and second trimesters, parvovirus infection can lead to pathology of the fetus: anemia, heart failure, hydrops, and disorders of physical and neurological development. In severe cases, the disease can result in fetal demise. This article presents a rare case of manifestation of B19 infection during pregnancy. At the 27th week of gestation, a sudden change in fetal movement occurred in a previously healthy pregnancy. The examination of both fetus and the mother revealed newly formed fetal subdural hematoma of unknown etiology and ventriculomegaly. Following extensive examination to ascertain the origin of fetal pathology, a maternal B19 infection was detected. Due to worsening fetal condition, a planned cesarean section was performed to terminate the pregnancy at 31 weeks of gestation. A preterm male newborn was delivered in a critical condition with congenital B19 infection, hydrocephalus, and severe progressive encephalopathy. The manifestation and the origin of the fetal condition remain partially unclear. The transplacental transmission of maternal B19 infection to the fetus occurs in approximately 30% of cases. The main method for diagnosing B19 infection is Polymerase Chain Reaction (PCR) performed on blood serum. In the absence of clinical manifestations, the early diagnosis of B19 infection is rarely achieved. As a result, the disease left untreated can progress inconspicuously and cause serious complications. Treatment strategies are limited and depend on the condition of the pregnant woman and the fetus. When applicable, intrauterine blood transfusion reduces the risk of fetal mortality. It is crucial to assess the predisposing factors of the infection and evaluate signs of early manifestation, as this may help prevent the progression and poor outcomes of the disease.

Haematological parameters and coagulation in umbilical cord blood following COVID-19 infection in pregnancy.

OBJECTIVE: The aim of this study was to evaluate infants, born to women with SARS-CoV-2 detected during pregnancy, for evidence of haematological abnormalities or hypercoagulability in umbilical cord blood. STUDY DESIGN: This was a prospective observational case-control study of infants born to women who had SARS-CoV-2 RNA detected by PCR at any time during their pregnancy (n = 15). The study was carried out in a Tertiary University Maternity Hospital (8,500 deliveries/year) in Ireland. This study was approved by the Hospital Research Ethics Committee and written consent was obtained. Umbilical cord blood samples were collected at delivery, full blood count and Calibrated Automated Thrombography were performed. Demographics and clinical outcomes were recorded. Healthy term infants, previously recruited as controls to a larger study prior to the outbreak of COVID-19, were the historical control population (n = 10). RESULTS: Infants born to women with SARS-CoV-2 had similar growth parameters (birth weight 3600 g v 3680 g, p = 0.83) and clinical outcomes to healthy controls, such as need for resuscitation at birth (2 (13.3%) v 1 (10%), p = 1.0) and NICU admission (1 (6.7%) v 2 (20%), p = 0.54). Haematological parameters (Haemoglobin, platelet, white cell and lymphocyte counts) in the COVID-19 group were all within normal neonatal reference ranges. Calibrated Automated Thrombography revealed no differences in any thrombin generation parameters (lag time (p = 0.92), endogenous thrombin potential (p = 0.24), peak thrombin (p = 0.44), time to peak thrombin (p = 0.94)) between the two groups. CONCLUSION: In this prospective study including eligible cases in a very large population of approximately 1500 women, there was no evidence of derangement of the haematological parameters or hypercoagulability in umbilical cord blood due to COVID-19. Further research is required to investigate the pathological placental changes, particularly COVID-19 placentitis and the impact of different strains of SARS-CoV-2 (particularly the B.1.1.7 and the emerging Delta variant) and the severity and timing of infection on the developing fetus.

Severity of illness by pregnancy status among laboratory-confirmed SARS-CoV-2 infections occurring in reproductive-aged women in Colombia.

BACKGROUND: Multiple studies have described increased risk of severe coronavirus disease (COVID-19) among pregnant women compared to nonpregnant women. The risk in middle-income countries where the distributions of age groups and preexisting conditions may differ is less known. OBJECTIVES: To determine whether pregnant women with SARS-CoV-2 infection are at increased risk for severe COVID-19 compared to nonpregnant women in Colombia. METHODS: We analysed national surveillance data from Colombia, of women aged 15-44 years with laboratory-confirmed infection with SARS-CoV-2 by molecular or antigen testing, from 6 March 2020 to 12 December 2020. An enhanced follow-up of pregnant women with COVID-19 was established to monitor pregnancy and birth outcomes. RESULTS: Of 371,363 women aged 15-44 years with laboratory-confirmed SARS-CoV-2 infection, 1.5% (n = 5614) were reported as pregnant; among those, 2610 (46.5%) were considered a complete pregnancy for reporting purposes at the time of analysis. Hospitalisation (23.9%) and death (1.3%) occurred more frequently among pregnant symptomatic women compared to nonpregnant symptomatic women (2.9% and 0.3%, respectively). Compared to nonpregnant symptomatic women, pregnant symptomatic women were at increased risk of hospitalisation (adjusted risk ratio [RR] 2.19, 95% confidence interval [CI] 2.07, 2.32) and death (RR 1.82, 95% CI 1.60, 2.07), after adjusting for age, type of health insurance and presence of certain underlying medical conditions. Among complete pregnancies, 55 (2.1%) were pregnancy losses, 72 (2.8%) resulted in term low birthweight infants and 375 (14.4%) were preterm deliveries. CONCLUSIONS: Although pregnant women were infrequently reported with laboratory-confirmed SARS-CoV-2 infection, pregnant symptomatic women with COVID-19 were at increased risk for hospitalisation and death compared to nonpregnant symptomatic women. Almost all infections we reported on were third-trimester infections; ongoing follow-up is needed to determine pregnancy outcomes among women infected earlier in pregnancy. Healthcare providers should counsel pregnant women about preventive measures to protect from SARS-CoV-2 infection and when to seek care.

Congenital infection of SARS-CoV-2 in live-born neonates: a population-based descriptive study.

OBJECTIVE: To evaluate the evidence of mother-to-child transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). METHODS: This is a descriptive, multicentre, observational study in nine tertiary care hospitals throughout Spain. The study population was women with coronavirus disease 2019 during pregnancy. Mother-to-child transmission was defined as positive real-time RT-PCR of SARS-CoV-2 in amniotic fluid, cord blood, placenta or neonatal nasopharyngeal swabs taken immediately after birth. RESULTS: We included 43 women with singleton pregnancies and one with a twin pregnancy, as a result we obtained 45 samples of placenta, amniotic fluid and umbilical cord blood. The median gestational age at diagnosis was 34.7 weeks (range 14-41.3 weeks). The median interval between positive RT-PCR and delivery was 21.5 days (range 0-141 days). Fourteen women (31.8%, 95% CI 18.6%-47.6%) were positive at the time of delivery. There was one singleton pregnancy with SARS-CoV-2 RT-PCR positive in the placenta, amniotic fluid and umbilical cord blood (2.2%, 95% CI 0.1%-11.8%). Nasopharyngeal aspiration was performed on 38 neonates at birth, all of which were negative (0%, 95% CI 0%-9.3%). In 11 neonates the nasopharyngeal aspiration was repeated at 24-48 hours, and one returned positive (9.1%, 95% CI 0.2%-41.3%). CONCLUSIONS: The presence of SARS-CoV-2 in placenta, amniotic fluid and cord blood shows that mother-to-child transmission is possible but uncommon.

A Preparedness Model for Mother-Baby Linked Longitudinal Surveillance for Emerging Threats.

INTRODUCTION: Public health responses often lack the infrastructure to capture the impact of public health emergencies on pregnant women and infants, with limited mechanisms for linking pregnant women with their infants nationally to monitor long-term effects. In 2019, the Centers for Disease Control and Prevention (CDC), in close collaboration with state, local, and territorial health departments, began a 5-year initiative to establish population-based mother-baby linked longitudinal surveillance, the Surveillance for Emerging Threats to Mothers and Babies Network (SET-NET). OBJECTIVES: The objective of this report is to describe an expanded surveillance approach that leverages and modernizes existing surveillance systems to address the impact of emerging health threats during pregnancy on pregnant women and their infants. METHODS: Mother-baby pairs are identified through prospective identification during pregnancy and/or identification of an infant with retrospective linking to maternal information. All data are obtained from existing data sources (e.g., electronic medical records, vital statistics, laboratory reports, and health department investigations and case reporting). RESULTS: Variables were selected for inclusion to address key surveillance questions proposed by CDC and health department subject matter experts. General variables include maternal demographics and health history, pregnancy and infant outcomes, maternal and infant laboratory results, and child health outcomes up to the second birthday. Exposure-specific modular variables are included for hepatitis C, syphilis, and Coronavirus Disease 2019 (COVID-19). The system is structured into four relational datasets (maternal, pregnancy outcomes and birth, infant/child follow-up, and laboratory testing). DISCUSSION: SET-NET provides a population-based mother-baby linked longitudinal surveillance approach and has already demonstrated rapid adaptation to COVID-19. This innovative approach leverages existing data sources and rapidly collects data and informs clinical guidance and practice. These data can help to reduce exposure risk and adverse outcomes among pregnant women and their infants, direct public health action, and strengthen public health systems.

Evolution of awareness and knowledge of congenital cytomegalovirus infection among health care providers in France between 2011 and 2018.

BACKGROUND: Cytomegalovirus (CMV) is the most frequent cause of congenital viral infection. Approximately 1 % of newborns are congenitally infected and in up to 10 % of them the consequences are severe. Antenatal and postnatal treatments, although promising, are still under evaluation. Hygiene counseling to prevent CMV infection is important and should be systematic. OBJECTIVE: To evaluate health care providers' awareness of CMV maternal and congenital infection in France. STUDY DESIGN: A questionnaire on CMV infection was sent in 2018 by e-mail to obstetricians, pediatricians, midwives and laboratory physicians, and members of medical or midwifery associations. We evaluated their knowledge concerning CMV epidemiology, transmission, symptoms in adults, newborns and long-term effects (scores from 0 to 30) and compared the results with those of our 2012 published study. RESULTS: Of the 597 respondents who completed the questionnaire, 91 % were unaware of the precise transmission route of CMV, 33 % wrongly thought thatin utero therapy for congenital CMV infection was a current standard of care in France, and less than half were familiar with the HAS (Haute Autorité de Santé) and CNGOF (Collège National des Gynécologues et Obstétriciens Français) recommendations. When respondents' knowledge of CMV was greater, patients were given more hygiene counseling. Between 2011 and 2018, knowledge improved among doctors and midwives concerning the route of transmission, the symptoms in adults, and the long-term effects of CMV infection. CONCLUSIONS: Knowledge is improving among healthcare providers, but gaps remain. To bridge these gaps, health care providers should improve their knowledge about congenital CMV by various means: medical reviews, continuing medical education, meetings, conferences, the Internet. Moreover, greater knowledge will allow for more effective counseling of pregnant women, as recommended by HCSP and CNGOF in France.

Immunization with Human Cytomegalovirus Core Fusion Machinery and Accessory Envelope Proteins Elicit Strong Synergistic Neutralizing Activities.

Human cytomegalovirus (HCMV) core fusion machinery proteins gB and gH/gL, and accessory proteins UL128/UL130/UL131A, are the key envelope proteins that mediate HCMV entry into and infection of host cells. To determine whether these HCMV envelope proteins could elicit neutralizing activities synergistically, we immunized rabbits with individual or various combinations of these proteins adsorbed to aluminum hydroxide mixed with CpG-ODN. We then analyzed serum neutralizing activities with multiple HCMV laboratory strains and clinical isolates. HCMV trimeric gB and gH/gL elicited high and moderate titers of HCMV neutralizing activity, respectively. HCMV gB in combination with gH/gL elicited up to 17-fold higher HCMV neutralizing activities compared to the sum of neutralizing activity elicited by the individual proteins analyzed with both fibroblasts and epithelial cells. HCMV gB+gH/gL+UL128/UL130/UL131A in combination increased the neutralizing activity up to 32-fold compared to the sum of neutralizing activities elicited by the individual proteins analyzed with epithelial cells. Adding UL128/UL130/UL131A to gB and gH/gL combination did not increase further the HCMV neutralizing activity analyzed with fibroblasts. These data suggest that the combination of HCMV core fusion machinery envelope proteins gB+gH/gL or the combination of gB and pentameric complex could be ideal vaccine candidates that would induce optimal immune responses against HCMV infection.

Clinical Features and Outcome of SARS-CoV-2 Infection in Neonates: A Systematic Review.

OBJECTIVE: The objective of this study is to systematically synthesize the currently available literature on various modes of transmission (congenital, intrapartum, and postpartum), clinical features and outcomes of SARS-CoV-2 infection in neonates. METHODS: We conducted a comprehensive literature search using PubMed, EMBASE, and Web of Science until 9 June 2020. A combination of keywords and MeSH terms, such as COVID-19, coronavirus, SARS-CoV-2, 2019-nCoV, severe acute respiratory syndrome coronavirus 2, neonates, newborn, infant, pregnancy, obstetrics, vertical transmission, maternal-foetal transmission and intrauterine transmission, were used in the search strategy. We included studies reporting neonatal outcomes of SARS-CoV-2 proven pregnancies or neonatal cases diagnosed with SARS-CoV-2 infection. RESULTS: Eighty-six publications (45 case series and 41 case reports) were included in this review. Forty-five case series reported 1992 pregnant women, of which 1125 (56.5%) gave birth to 1141 neonates. A total of 281 (25%) neonates were preterm, and caesarean section (66%) was the preferred mode of delivery. Forty-one case reports describe 43 mother-baby dyads of which 16 were preterm, 9 were low birth weight and 27 were born by caesarean section. Overall, 58 neonates were reported with SARS-CoV-2 infection (4 had a congenital infection), of which 29 (50%) were symptomatic (23 required ICU) with respiratory symptoms being the predominant manifestation (70%). No mortality was reported in SARS-CoV-2-positive neonates. CONCLUSION: The limited low-quality evidence suggests that the risk of SARS-CoV-2 infections in neonates is extremely low. Unlike children, most COVID-positive neonates were symptomatic and required intensive care. Postpartum acquisition was the commonest mode of infection in neonates, although a few cases of congenital infection have also been reported.

SARS-CoV-2: Is it the newest spark in the TORCH?

Amid the rapidly evolving global coronavirus disease 2019 (COVID-19) pandemic that has already had profound effects on public health and medical infrastructure globally, many questions remain about its impact on child health. The unique needs of neonates and children, and their role in the spread of the virus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) should be included in preparedness and response plans. Fetuses and newborn infants may be uniquely vulnerable to the damaging consequences of congenitally- or perinatally-acquired SARS-CoV-2 infection, but data are limited about outcomes of COVID-19 disease during pregnancy. Therefore, information on illnesses associated with other highly pathogenic coronaviruses (i.e., severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome [MERS]), as well as comparisons to common congenital infections, such as cytomegalovirus (CMV), are warranted. Research regarding the potential routes of acquisition of SARS-CoV-2 infection in the prenatal and perinatal setting is of a high public health priority. Vaccines targeting women of reproductive age, and in particular pregnant patients, should be evaluated in clinical trials and should include the endpoints of neonatal infection and disease.
