ABSTRACT

OBJECTIVE: To determine whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is present in the vagina of women diagnosed with coronavirus disease-19 (COVID-19) pneumonia. STUDY DESIGN: The study was conducted prospectively in a university affiliated hospital. Forty-one women of reproductive age whose nasopharyngeal PCR test were positive for SARS-CoV-2 and clinically diagnosed with pneumonia were included in the study. Vaginal swabs were obtained for SARS-CoV-2 PCR tests when the patients were admitted to the inpatient service before pneumonia treatment was initiated. RESULTS: Vaginal swab samples of 38 patients were analysed with SARS-CoV-2 PCR tests. None of the vaginal swabs were positive for SARS-CoV-2. CONCLUSIONS: SARS-CoV-2 does not infect the vagina of women diagnosed with SARS-CoV-2 pneumonia.

ABSTRACT

The aim was to investigate the association of the delivery mode and vertical transmission of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) through the samples of vaginal secretions, placenta, cord blood, or amniotic fluid as well as the neonatal outcomes. This cross-sectional study presents an analysis of prospectively gathered data collected at a single tertiary hospital. Sixty-three pregnant women with confirmed coronavirus disease 2019 (COVID-19) participated in the study. Vertical transmission of SARS-CoV-2 was analyzed with reverse transcriptase-polymerase chain reaction (RT-PCR) tests and blood tests for immunoglobulin G (IgG)-immunoglobulin M (IgM) antibodies. All patients were in the mild or moderate category for COVID-19. Only one placental sample and two of the vaginal secretion samples were positive for SARS-CoV-2. Except for one, all positive samples were obtained from patients who gave birth by cesarean. All cord blood and amniotic fluid samples were negative for SARS-CoV-2. Two newborns were screened positive for COVID-19 IgG-IgM within 24 h after delivery, but the RT-PCR tests were negative. A positive RT-PCR result was detected in a neof a mother whose placenta, cord blood, amniotic fluid, and vaginal secretions samples were negative. He died due to pulmonary hemorrhage on the 11th day of life. In conclusion, we demonstrated that SARS-CoV-2 can be detectable in the placenta or vaginal secretions of pregnant women. Detection of the virus in the placenta or vaginal secretions may not be associated with neonatal infection. Vaginal delivery may not increase the incidence of neonatal infection, and cesarean may not prevent vertical transmission. The decision regarding the mode of delivery should be based on obstetric indications and COVID-19 severity.

ABSTRACT

INTRODUCTION: Given the important role of sexual activity in most people's lives, in response to the question of whether the coronavirus is transmitted through sexual contact, this study was conducted to investigate the association of coronavirus transition with sexual contact. METHODS: Based on the PRISMA checklist, we review published articles on sexual contact with the Corona virus until 15 February 2021. Electronic databases based on search strategy including PubMed, Scopus, Web of Science was searched to identify relevant papers in English language. RESULTS: Retrieved from 4671, 29 titles and abstracts articles screened, eight were excluded. There were 21 articles in the selection criteria. Of the 21 studies whose full text was read, only 5 studies stated that coronavirus was not transmitted through sexual contact, and 16 articles argued that sexual transmission of the virus could not be ignored. Most studies have confirmed the transmission of the virus through semen, but its transmission through vaginal secretions is unknown. CONCLUSION: Transmission of the virus through semen should be taken seriously in patients and the necessary education should be given to men and their sexual partners. Health care providers need to increase their knowledge and awareness to provide the best practices to reduction the risks related to Covid-19 sexual transmission through counseling and appropriate approaches.

ABSTRACT

Pregnant women display a higher risk of progression to disease and higher viral loads during infections due to their more permissive, tolerogenic immune system. However, only few studies have focused on SARS-CoV-2 intrapartum vertical transmission via vaginal secretions or faeces. The aim of this study was to investigate the presence of the virus in vaginal, rectal and blood specimens from pregnant women characterized by different COVID-19 disease severity. We enrolled 56 SARS-CoV-2-positive pregnant women, of which 46 (82%) were in the third trimester of pregnancy, 6 (10%) in the second and 4 (7%) in the first. QPCR was performed to detect the virus in vaginal and rectal swabs and in plasma samples. SARS-CoV-2 was detected in 27% of rectal swabs of pregnant women in the third trimester, while no virus particles were detected in vaginal swabs of the same patients. Furthermore, only 4% plasma samples tested positive to SARS-CoV-2. No virus was detected in newborn's nasopharyngeal swabs. Despite the low number of subjects enrolled, our data suggest that, while theoretically possible, intrapartum vaginal or orofecal SARS-CoV-2 transmission seems to be unlikely.

ABSTRACT

OBJECTIVE: To study vaginal delivery outcomes and neonatal prognosis and summarize the management of vaginal delivery during the COVID-19 pandemic. METHODS: A retrospective analysis of medical records and comparison of vaginal delivery outcomes between 10 pregnant women with clinical diagnosis of COVID-19 and 53 pregnant women without COVID-19 admitted to Zhongnan Hospital of Wuhan University between January 20 and March 2, 2020. Results of laboratory tests, imaging tests, and SARS-CoV-2 nucleic acid tests were also analyzed in neonates delivered by pregnant women with clinical diagnosis of COVID-19. RESULTS: There were no significant differences in gestational age, postpartum hemorrhage, and perineal resection rates between the two groups. There were no significant differences in birth weight of neonates and neonatal asphyxia rates between the two groups. Neonates delivered by pregnant women with clinical diagnosis of COVID-19 tested negative for SARS-CoV-2 infection. CONCLUSIONS: Under the premise of full evaluation of vaginal delivery conditions and strict protection measures, pregnant women with ordinary type COVID-19 can try vaginal delivery without exacerbation of COVID-19 and without increasing the risk of SARS-CoV-2 infection in neonates.

ABSTRACT

OBJECTIVE: To determine whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is present in the vaginal secretions of both reproductive-aged and postmenopausal women during acute SARS-CoV-2 infection. DESIGN: Prospective study. SETTING: A single tertiary, university-affiliated medical centre in Israel. Time period, 1 June 2020 through to 31 July 2020. POPULATION: Women who were hospitalised in a single tertiary medical centre, who were diagnosed with acute SARS-CoV-2 infection by a nasopharyngeal RT-PCR test. METHODS: Women were diagnosed with acute SARS-CoV-2 infection by a nasopharyngeal RT-PCR test. Vaginal RT-PCR swabs were obtained from all study participants after a proper cleansing of the perineum. MAIN OUTCOME MEASURES: Detection of SARS-CoV-2 in vaginal RT-PCR swabs. RESULTS: Vaginal and nasopharyngeal swabs were obtained from 35 women, aged 21-93 years. Twenty-one women (60%) were in their reproductive years, of whom, five were in their third trimester of pregnancy. Most of the participants (57%) were healthy without any underlying medical conditions. Of the 35 patients sampled, 2 (5.7%) had a positive vaginal RT-PCR for SARS-CoV-2, one was premenopausal and the other was a postmenopausal woman. Both women had mild disease. CONCLUSION: Our findings contradict most previous reports, which did not detect the presence of viral colonisation in the vagina. Although passage through the birth canal exposes neonates to the vaginal polymicrobial flora, an acquisition of pathogens does not necessarily mandate neonatal infection or clinical disease. Nevertheless, when delivering the infant of a woman with acute SARS-CoV-2 infection, a clinician should consider the possibility of vaginal colonisation, even if it is uncommon. TWEETABLE ABSTRACT: When delivering the infant of a woman with acute SARS-CoV-2 infection, a clinician should consider the possibility of vaginal colonisation.

ABSTRACT

The risk of vertical transmission during vaginal delivery in COVID-19 pregnant patients is currently a topic of debate. Obstetric norms on vaginal birth assistance to reduce the potential risk of perinatal infection should be promoted by ensuring that the risk of contamination from maternal anus and faecal material is reduced during vaginal delivery.

ABSTRACT

OBJECTIVE: To assess whether vaginal secretions and breast milk of women with coronavirus disease 2019 (COVID-19) contain severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). DESIGN: Single centre cohort study. SETTING: Renmin Hospital of Wuhan University, Wuhan, Hubei province, China. POPULATION: We studied 13 SARS-CoV-2-infected pregnant women diagnosed between 31 January and 9 March 2020. METHODS: We collected clinical data, vaginal secretions, stool specimens and breast milk from SARS-CoV-2-infected women during different stages of pregnancy and collected neonatal throat and anal swabs. MAIN OUTCOMES AND MEASURES: We assessed viral presence in different biosamples. RESULTS: Of the 13 women with COVID-19, five were in their first trimester, three in their second trimester and five in their third trimester. Of the five women in their third trimester who gave birth, all delivered live newborns. Among these five deliveries, the primary adverse perinatal outcomes included premature delivery (n = 2) and neonatal pneumonia (n = 2). One of nine stool samples was positive; all 13 vaginal secretion samples, and five throat swabs and four anal swabs collected from neonates, were negative for the novel coronavirus. However, one of three samples of breast milk was positive by viral nucleic acid testing. CONCLUSIONS: In this case series of 13 pregnant women with COVID-19, we observed negative viral test results in vaginal secretion specimens, suggesting that a vaginal delivery may be a safe delivery option. However, additional research is urgently needed to examine breast milk and the potential risk for viral contamination. TWEETABLE ABSTRACT: New evidence for the safety of vaginal delivery and breastfeeding in pregnant women infected with SARS-CoV-2, positive viral result in a breast-milk sample.

ABSTRACT

OBJECTIVE: To report mode of delivery and immediate neonatal outcome in women infected with COVID-19. DESIGN: Retrospective study. SETTING: Twelve hospitals in northern Italy. PARTICIPANTS: Pregnant women with COVID-19-confirmed infection who delivered. EXPOSURE: COVID 19 infection in pregnancy. METHODS: SARS-CoV-2-infected women who were admitted and delivered from 1 to 20 March 2020 were eligible. Data were collected from the clinical records using a standardised questionnaire on maternal general characteristics, any medical or obstetric co-morbidity, course of pregnancy, clinical signs and symptoms, treatment of COVID 19 infection, mode of delivery, neonatal data and breastfeeding. MAIN OUTCOME AND MEASURES: Data on mode of delivery and neonatal outcome. RESULTS: In all, 42 women with COVID-19 delivered at the participating centres; 24 (57.1%, 95% CI 41.0-72.3) delivered vaginally. An elective caesarean section was performed in 18/42 (42.9%, 95% CI 27.7-59.0) cases: in eight cases the indication was unrelated to COVID-19 infection. Pneumonia was diagnosed in 19/42 (45.2%, 95% CI 29.8-61.3) cases: of these, 7/19 (36.8%, 95% CI 16.3-61.6) required oxygen support and 4/19 (21.1%, 95% CI 6.1-45.6) were admitted to a critical care unit. Two women with COVID-19 breastfed without a mask because infection was diagnosed in the postpartum period: their newborns tested positive for SARS-Cov-2 infection. In one case, a newborn had a positive test after a vaginal operative delivery. CONCLUSIONS: Although postpartum infection cannot be excluded with 100% certainty, these findings suggest that vaginal delivery is associated with a low risk of intrapartum SARS-Cov-2 transmission to the newborn. TWEETABLE ABSTRACT: This study suggests that vaginal delivery may be associated with a low risk of intrapartum SARS-Cov-2 transmission to the newborn.

ABSTRACT

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is spread mainly through respiratory droplets or direct contact. However, the infection condition of the genital system is unknown. Our aim in this study was to determine if SARS-CoV-2 is present in the vaginal fluid of women with coronavirus disease 2019 (COVID-19). METHODS: Ten women with confirmed severe COVID-19 pneumonia admitted to the Tongji Zhongfa Hospital intensive care unit from 4 February 2020 through 24 February 2020 were included. Clinical records, laboratory results, and computed tomography examinations were retrospectively reviewed. The potential for genital infection was accessed by testing for the presence of SARS-CoV-2 in vaginal fluids obtained from vaginal swab samples. Reverse transcriptase polymerase chain reaction was used to confirm the SARS-CoV-2 infection in vaginal fluids. RESULTS: The clinical characteristics of the 10 women were similar to those reported in other severe COVID-19 patients. All 10 patients were tested for SARS-CoV-2 in vaginal fluid, and all samples tested negative for the virus. CONCLUSIONS: Findings from this small group of cases suggest that SARS-CoV-2 virus does not exist in the vaginal fluids of severe COVID-19 patients.
