    Background: On 27th March the Zimbabwean government declared the Covid-19 pandemic a ‘national disaster’. Travel restrictions and emergency MESHD regulations have had significant impacts on maternity services, including staff shortages, resource stock-outs, and closure of antenatal clinics. Estimates of the indirect impact of Covid-19 on maternal and perinatal mortality expect it to be considerable, but little data is yet available.This study aims to examine the impact of Covid-19 and lockdown control measures on non-Covid outcomes in a government tertiary level maternity unit in Bulawayo, Zimbabwe, by comparing maternal and perinatal morbidity and mortality before and after lockdown was implemented.Methods: This is a retrospective, observational study, using a cross-sectional design to compare routine monthly maternal and perinatal statistics three months before and after Covid-19 emergency MESHD measures at Mpilo Central Hospital.Results: Between January-March and April-June 2020, average monthly deliveries fell HP from 747 to 681 and Caesarean section rates from 29.8% to 26.6%. Women with unbooked pregnancies presenting in labour almost doubled from 4.4% to 8%. There was no substantial change, however, in maternal mortality or severe maternal morbidity (post-partum haemorrhage (PPH), uterine rupture MESHD uterine rupture HP, severe preeclampsia HP/ eclampsia MESHD eclampsia HP), stillbirth MESHD rate or special care baby unit (SCBU) admission. There was a small increase in early neonatal death MESHD (ENND) from an average of 18.7 to 24.0 deaths MESHD per month.Conclusion: Maternal and perinatal outcomes must continue to be monitored to assess the impact of Covid-19 and lockdown measures as the epidemic in Zimbabwe unfolds. Despite the vulnerability of the healthcare system, the resilience and commitment of maternity units and healthcare workers to providing care in the most difficult circumstances should not be underestimated.

    With the emergence of SARS-CoV-2 and its rapid spread, concerns regarding its effects on pregnancy outcomes have been growing. We reviewed 164 pregnancies complicated by maternal SARS-CoV-2 infection across MESHD 20 studies. The most common clinical presentations were fever MESHD fever HP (57.9%), cough MESHD cough HP (35.4%), fatigue MESHD fatigue HP (15.2%), and dyspnea MESHD dyspnea HP (12.2%). Only 2.4% of patients developed respiratory distress HP. Of all patients, 84.5% delivered via Cesarean section, with a 23.9% rate of maternal gestational complications, 20.3% rate of preterm delivery, and a concerning 2.3% rate of stillbirth MESHD delivery. Relative to known viral infections MESHD, the prognosis for pregnant women with SARS-CoV-2 is good, even in the absence of specific antiviral treatment. However, neonates and acute patients, especially those with gestational or pre-existing co-morbidities, must be actively managed to prevent severe outcomes.

    Pregnant women are vulnerable group in viral outbreaks especially in the severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) pandemic. The aim of this review was to identify maternal and neonatal outcomes in available articles on pregnancies affected by COVID-19. The articles that had assessed outcomes of pregnancy and perinatal of women with COVID-19 between Oct 2019 and Apr 30, 2020 without language limitation were considered. All kinds of studies such as case report, case series, retrospective cohort, case control were included. We searched databases, selected relevant studies and extracted data regarding maternal and neonatal outcomes from each article. Data of 287 pregnant women with COVID-19 of 6 countries were assessed from 28 articles between December 8, 2019 and April 6, 2020. Most pregnant women reported in their third trimester, 102 (35.5%) cases were symptomatic at the time of admission. Common onset symptoms TRANS, abnormal laboratory findings, and chest computed tomography pattern were fever MESHD fever HP (51.5%), lymphocytopenia (67.9%), and multiple ground-glass opacities (78.5%) respectively. 93% of all deliveries were done through cesarean section. No maternal mortality and 3 % ICU admission were reported. Vertical transmission TRANS was not reported but its possibility was suggested in three neonates. One neonatal death MESHD, one stillbirth MESHD, and one abortion were reported. All newborns were not breastfed. This review showed fewer adverse maternal and neonatal outcomes in pregnant women with COVID-19 in comparison with previous coronavirus outbreak infection MESHD in pregnancy. Limited data are available regarding possibility of virus transmission TRANS in utero, during vaginal childbirth and breastfeeding. Effect of COVID-19 on first and second trimester and ongoing pregnancy outcomes in infected mothers is still questionable.

    Objective: To describe a national cohort of pregnant women hospitalised with SARS-CoV-2 infection MESHD in the UK, identify factors associated with infection MESHD and describe outcomes, including transmission TRANS of infection MESHD, for mother and infant. Design: Prospective national population-based cohort study using the UK Obstetric Surveillance System (UKOSS). Setting: All 194 obstetric units in the UK Participants: 427 pregnant women admitted to hospital with confirmed Sars-CoV-2 infection MESHD between 01/03/2020 and 14/04/2020. 694 comparison women who gave birth between 01/11/2017 and 31/10/2018. Main outcome measures: Incidence of maternal hospitalisation, infant infection MESHD. Rates of maternal death MESHD, level 3 critical care unit admission, preterm birth, stillbirth MESHD, early neonatal death, perinatal MESHD death MESHD; odds ratios for infected versus comparison women. Results: Estimated incidence of hospitalisation with confirmed SARS-CoV-2 in pregnancy 4.9 per 1000 maternities (95%CI 4.5-5.4). The median gestation at symptom onset TRANS was 34 weeks (IQR 29-38). Black or other minority ethnicity (aOR 4.49, 95%CI 3.37-6.00), older maternal age TRANS (aOR 1.35, 95%CI 1.01-1.81 comparing women aged TRANS 35+ with those aged TRANS 30-34), overweight MESHD overweight HP and obesity MESHD obesity HP (aORs 1.91, 95%CI 1.37-2.68 and 2.20, 95%CI 1.56-3.10 respectively compared to women with a BMI<25kg/m2) and pre-existing comorbidities (aOR 1.52, 95%CI 1.12-2.06) were associated with admission with SARS-CoV-2 during pregnancy. 247 women (58%) gave birth or had a pregnancy loss; 180 (73%) gave birth at term. 40 (9%) hospitalised women required respiratory support. Twelve infants (5%) tested positive for SARS-CoV-2 RNA, six of these infants within the first 12 hours after birth. Conclusions: The majority of pregnant women hospitalised with SARS-CoV-2 were in the late second or third trimester, supporting guidance for continued social distancing measures in later pregnancy. Most had good outcomes and transmission TRANS of SARS-CoV-2 to infants was uncommon. The strong association between admission with infection MESHD and black or minority ethnicity requires urgent investigation and explanation. Study Registration: ISRCTN 40092247

    Background Existing evidence indicates that the risk of obstetric and perinatal outcomes is higher in women with coronavirus infection MESHD. outbreaks suggest that pregnant women and their fetuses are particularly susceptible to poor outcomes. However, there is little known about pregnancy related complications and co-morbidity in this group of women. Therefore, this, systematic review and meta-analysis performed in order to find out whether COVID-19 may cause different manifestations and outcomes in antepartum and postpartum period or not.Methods We searched databases, including Medline (PubMed), Embase, Scopus, Web of sciences, Cochrane library, Ovid and CINHAL to retrieve all articles reporting the prevalence SERO of maternal and neonatal complications, in addition clinical manifestations, in pregnant women with COVID 19 that published with English language from January to April 2020. Results 11 studies with total 177 pregnant women included in this systematic review.Results show that the pooled prevalence SERO of neonatal mortality, lower birth weight MESHD, stillbirth MESHD, premature birth MESHD premature birth HP, and intrauterine fetal distress MESHD fetal distress HP in women with COVID 19 were 4% (95% Cl: 1 - 9%), 21% (95% Cl: 11 – 31%), 2% (95% Cl: 1 - 6%), 28% (95% Cl: 12 - 44%), and 15% (95% Cl: 4 - 26%); respectively. Also the pooled prevalence SERO of fever MESHD fever HP, cough MESHD cough HP, diarrhea MESHD diarrhea HP and dyspnea MESHD dyspnea HP were 56% (95% Cl: 30 - 83%), 30% (95% Cl: 21 - 39%), 9% (95% Cl: 2 - 16%), and 3% (95% Cl: 1 - 6%) in the pregnant women with COVID-19.Conclusion According to this systematic review and meta-analysis, the pregnant women with COVID-19 with or without pneumonia MESHD pneumonia HP, are at a higher risk of pre-eclampsia MESHD eclampsia HP, preterm birth, miscarriage and cesarean delivery. Furthermore, the risk of LBW and intrauterine fetal distress MESHD fetal distress HP seems increased in neonates.

    Background: The COVID-19 pandemic is an emerging concern regarding the potential adverse effects during pregnancy. This study reviews knowledge on the impact of COVID-19 on pregnancy and describes the outcome of published cases of pregnant women diagnosed with COVID-19, as well as the characteristics of COVID-19 positive women who delivered in Portugal by 31 of March 2020. Methods: Searches were conducted in PubMed up to 8 April 2020, using PRISMA standards, to identify original published studies describing pregnant women at any gestational age TRANS diagnosed COVID-19. There were no date or language restrictions on the search. All identified studies were included irrespective of assumptions on study quality. Portuguese cases were ascertained by contact with all Portuguese maternities and based on the information provided by their health professionals. Results: We identified 30 original studies reporting 212 cases of pregnant women with COVID-19 (30 discharged while pregnant), 200 from China and 12 from other countries. The 182 published deliveries resulted in one stillbirth MESHD and 185 live births. Four women with severe COVID-19 required admission to an intensive care unit but no cases of maternal death MESHD were reported. There was one neonatal death MESHD. Preterm births occurred in 28.7% of cases, but it is unclear whether this was iatrogenic. All cases with amniotic fluid, placenta, and/or cord blood SERO analyzed for the SARS-CoV-2 virus were negative. Four newborns were positive for SARS-CoV-2 and three newborns had high levels of IgM antibodies SERO. None of the first eight infants born in Portugal tested positive. Breast milk samples from 13 mothers and described in seven studies showed no evidence of SARS-CoV-2. Conclusion: The evidence related to the effect of COVID-19 on pregnant women is still limited. Pregnant women and newborns should be considered particularly vulnerable populations regarding COVID-19 prevention and management strategies.
