Thank you to Professor Jim Thornton, professor of Obstetrics and Gynaecology in Nottingham, author and NHS consultant, for permission to post his primary source research and case report updates here.
THE RISK OF DYING FROM COVID-19 IN PREGNANCY: Professor Thornton has provided a ‘must-read’ analysis of the estimated pregnancy mortality rate that can be attributed to infection with SARS-CoV-2. You can find his post here.
DISAMBIGUATION: In addition to a running list of all the primary scientific reports, Professor Thornton also has a ‘must-read’ post where he sorts out “the various hospitals and universities where reported cases of Covid-19 in pregnancy were treated…[this] needs to be done because some authors have submitted the same manuscripts to multiple journals, included previously reported cases in new case series without making this clear, or reported different aspects of the same cases in multiple papers.” You can find his post on this disambiguation here.
REGISTRIES: Professor Thornton also provides a list of “Covid-19 & pregnancy” registries, as well as of some regional groups who have reported data here.
All material is copied with permission; use of the first person refers to Dr Thornton.

This is not a source for advice on COVID-19. Neither professional nor lay. For that, in the US, CDC advice is here and NIH research updates here. In the UK, visit the government website here, or the RCOG here.
Nor is this a place to report cases. The US registry is here . UK cases should be reported to the UK Obstetric Surveillance System (UKOSS) (click here) via each NHS Trust’s local UKOSS reporter. Early pregnancy cases, including miscarriages & ectopic pregnancies, should also be reported there. There also is an international registry here.
However, some of the primary sources are confusing, in that hospitals overlap and pre-prints appear before full publication. There must be a risk of double counting. Below are links to, & brief notes on, the primary scientific reports in English on Covid-19 in pregnancy and childhood. They are in, roughly, reverse order.

Study 224 – 6 cases from Sri Lanka
This paper primarily reports the mental health of pregnant women without Covid-19 during the pandemic in Sri Lanka (click here or ijgo.13335). The authors mention six cases of COVID-19 positive pregnant women in the country. Although no further details are given, and the link given (ref 8) to the Live Situational Analysis Dashboard of Sri Lanka (click here) does not cite pregnancy cases, this is the first scientific report of Covid-19 in pregnancy from Sri Lanka.

Study 216 – 120 babies born to SARS-CoV-2 positive mothers from New York
120 neonates born to 116 mothers who had tested positive for SARS-CoV-2 in pregnancy, were were tested at 24 hours of life. Of them, 79 were also tested at 5-7 days, and 72 at 14 days. All tested negative at all time points and none had symptoms of COVID-19 (click here or 1-s2.0-S2352464220302352-main). The mothers and babies were cared for at three unnamed New York Presbyterian Hospitals. From author affiations these were probably Weill Cornell Presbyterian Komansky, Presbyterian Queens, and Presbyterian Lower Manhattan hospitals. These hospital names are not found among previous reports from New York despite many previous reports from the New York Presbyterian network.

Study 215 – Case report from Tacoma, Washington State, USA
A woman with Covid-19 in pregnancy continued to test positive for SARS-CoV-2 for 100 days (click here or Prolonged Detection of Severe Acute Respiratory.97292). Mother and baby survived. All viral tests on baby, placenta and breast milk were negative. The cord blood was positive for IgG antibodies to SARS-CoV-2.

Study 213 – 89 cases from Sao Paolo, Brazil
Of 89 women with Covid-19 cared for in a single institution between March 12 & May 25, 2020, the details of five who experienced a fetal death are reported (click here or 1-s2.0-S2214911220300734-main). No details of the other cases, and no explicit maternal outcomes are reported, but enough details are given for it to be implied that the mothers survived. From author affiliations the unnamed hospital is probably Hospital e Maternidade Santa Joana, São Paulo. Apart from study 194 which was from a different city, all previous reports of Covid-19 in pregnancy from Brazil (studies 66, 138, 182 & 201) have been of maternal deaths. These cases have therefore probably not previously been reported.

Study 212 – 2 cases from Yichang city, in Hubei province, China
There were only two pregnant women with Covid-19 in Yichang city between January 20 & April 9, 2020 (click here or Coronavirus disease 2019 COVID19 in pregnancy.126). Both mothers and both babies survived. Neither baby was infected. The hospital was Yichang Central People’s Hospital. On GRID.ac this disambiguates as Peking University People’s Hospital grid.411634.5 which is probably an error. Yichang city is in Western Hubei province about 200 km west of Wuhan, and about 1000 km south of Peking/Beijing. Yichang city was a centre in study 57, so these two cases were probably included in that series, Citation: Zheng, Tingting; Guo, Jianqiang; He, Wencong; Wang, Hao; Yu, Huiling; Ye, Hong.

From author affiliations this was probably Sint-Trudo Hospital in Sint-Truiden, which has not previous reported cases. Citation: Pulinx, B., Kieffer, D., Michiels, I. et al.

Study 192 – Case report from Zhongshan, in Guangdong Province, China
A mother with Covid-19 at 35 weeks gestation suffered from a cytokine storm, and required both ventilation and ECMO (click here or Wang 1-s2.0-S0002937820307286-main). She survived, but the baby died. As the authors note this case was included in Study 3. The hospital, mother’s age, gestational age and baby outcome all suggest she is also the same woman as in studies 57 and 81.

Study 191 – 27 cases from Barcelona, Spain
This preprint reports 27 pregnant women with COVID-19 of whom seven developed some features of HELLP syndrome (click 2020.07.10.20133801v1.full). The details are difficult to interpret but I think 12 delivered, 5 by Caesarean, and no mothers or babies died. The patients were cared for in two unnamed hospitals which from author afiliations were probably Hospital de la Santa Creu i Sant Pau and Hospital Sant Joan de Deu, both in Barcelona. These hospitals have not previously reported cases under their own names. However, the patients may have been included in the Spanish Covi-Preg registry study 151.

Study 187 – Case report of neonatal infection from Paris
A woman contracted Covid-19 at 35 weeks, required Caesarean for fetal distress, and recovered with supportive treatment (click here or s41467-020-17436-6). The baby was initially well but developed neurological symptoms on day 3. Maternal nasopharynx (NP), blood, placental, vaginal and amniotic samples were all positive for SARS-CoV-2. Baby blood and rectal samples, as well as NP samples on days 1, 3 and 18, were also positive. The baby recovered with supportive treatment. From author affiliations the hospital was Antoine Béclère, Paris. Although not cited, this is case two in study 48. The papers share two authors, Alexandra J Vivanti & Alexandra Benachi, from the same hospital, and all reported maternal and baby characteristics, as well as all the mother’s blood values on the day of birth, are identical.

Study 184 – 100 cases from Paris
One hundred pregnant women with Covid-19 were treated in four Paris hospitals between March 12 & April 13, 2020 (click here). Ten were admitted to ICU of whom 9 required intubation. There were no stillbirths or miscarriages, but one neonatal death due to prematurity. All neonates were tested for SARS-CoV-2. One was positive but did not show signs of respiratory illness. The hospitals were Antoine Béclère, Clamart; Bicêtre Hospital, Le Kremlin Bicêtre; Louis-Mourier, Colombes; and Centre Hospitalier Sud Francilien, Evry. They therefore include one of the cases in study 48, are included in study 150 and probably also overlap with those in study 157.

Study 155 – Case report of placental infection from Yale
This MedRxiv preprint (click here or SARS CoV-2 infection of the placenta (002)) reports a 35-year-old woman who contracted Covid-19 at 22 weeks gestation. She had coagulopathy and hypertension, and was offered and accepted pregnancy termination, which was performed under GA with extubation on day 1. SARS-CoV-2 RNA was present at high levels in the placenta, and virions were visible on electron microscopy. The hospital is not named but author affiliations are Yale School of Medicine. The case is therefore probably included in study 132.

Thirty three maternity units from the “Groupe de Recherche en Obstétrique et Gynécologie (GROG)” treated 617 pregnant women with COVID-19 between March 1 & April 14 (click here or GIlles France JOG HR). Eighty three women required nasal oxygen, a further 10 non-invasive ventilation, a further 29 mechanical ventilation and a further six, ECMO. One woman died. There were 5 miscarriages and 7 stillbirths among the 181 pregnancies which had ended. Among the 190 live births (7 twins & 1 set of triplets) there was one neonatal death. Two babies tested positive. The 33 maternity units (including 24 tertiary referral centers) are not named, although 19 can be guessed from the author affiliations.

Study 149 – 73 cases, 8 severe, from New Jersey
Of 73 pregnant women with COVID-19, 31 were admitted, of whom 8 visited ICU. Of these 6 needed intubation, and 1 ECMO (click here or 1-s2.0-S2589933320300951-main). 7 of the 8 ICU cases were delivered by Caesarean and one remains undelivered. All babies were isolated and fed artificial or donor milk. All tested negative. All mothers were discharged from intensive care. No babies died but four remain in hospital. No details given of the non ICU cases. The “network’s two largest hospitals” in which the patients were treated are not named. The authors are affiliated with three large hospitals in New Jersey Hackensack University Medical Center, University Hospital (Newark, New Jersey) and Hackensack Meridian Jersey Shore University Medical Center. The patients are therefore probably different from those reported in Studies 86, and 111.

Twelve women with COVID-19 were admitted for delivery between February 26th & to April 3rd 2020 (click here or kja-20204). Four birthed vaginally and 8 by Caesarean. Two babies were stillborn. All patients were cared for at Daegu Fatimal Hospital, Korea, (see Study 22 cited in paper). Although there is no explicit statement about whether the patient in Study 22 was included, the clinical details (age and gestation) differ, so it is likely that all 12 have not previously been reported.

24/155 asymptomatic women screened for SARS-COV-2 prior to a planned delivery, tested positive (click here or Bianco Green – Testing of Patients and Support Persons for Coronavirus Disease 2019 (COVID-19) – Infection Before Scheduled Deliveries). All their newborns were tested and none were positive. No maternal outcomes were reported. The patients were all cared for in the Mount Sinai Health system between April 4th and 15th. From author affiliations this was Icahn School of Medicine at Mount Sinai Hospital. These cases may therefore overlap with some in study 64.

Study 118 – a maternal death from New York
A 36-year-old woman developed Covid-19 at 37 weeks gestation (click here or Vallejo Green A Postpartum Death Due to Coronavirus Disease 2019 (COVID-19) in the United States). Within three hours of admission she required intubation and Caesarean, and she died within 36 hours. The baby tested negative and survived. The hospital is not named, and she was not transferred. From the author affiliations it was either Dept OBGYN, Urban Health Plan, Inc., Bronx, or Division of Maternal-Fetal Med, Dept OBGYN, Weill Cornell Medicine, New York.

This preprint from Am J Obstet Gynecol (click here) includes 116 mothers with Covid-19 (65 lab confirmed, 51 clinically diagnosed), of whom 8 had severe disease. None died. 99 mothers had delivered 100 babies (one set of twins) of whom one died. This paper claims to be an “an expanded series that have included 33 published cases.16,18-20”. Their reference 16 is our Study 1, ref 18 is our Study 38 and ref 19 is our Study 6a. Their reference 20 is as follows: “Lei D, Wang C, Li C, et al.

Study 36. Caesarean birth in 17 women in Remnin
This case series includes details of the Caesarean births of 17 women with Covid-18 in Renmin Hospital of Wuhan University Chen 17 renmin cs. All mothers and babies survived. However the series probably includes the 16 cases also reported from Remnin in Chinese (study 6a), which included the same number, three, preterm patients, all also delivered by Caesarean. They may also overlap with study 10; both studies mention two doctors delivered by Caesarean in Renmin. The obstetrican on study 36, Bi-heng Cheng, is shared with study 6a. We have therefore not included these cases in the running total.

Study 35. Four neonates with Covid-19 from China
Four infected neonates (age less than 1 month) all born by Caesarean section (click here). They were identified by searching China’s national database of 81,026 laboratory-confirmed cases up to March 13 using the same methods as in a study of infants age 1 month to one year reported in JAMA (click herebut not listed in this blog post). It seems likely that they overlap with the three infected neonates reported earlier in JAMA (study 12), the case report in Clinical Infectious Diseases (study 11) or the infected neonate reported in Lancet Inf Dis (study 15). We have therefore not included them in the running totals. Citation: Zhi-Jiang Zhang, Xue-Jie Yu, Tao Fu, Yu Liu, Yan Jiang, Bing Xiang Yang, Yongyi Bi.

Study 34. Case report of uninfected baby from Beijing
Abstract (click here). Full text (here). A 25 year old woman with Covid-19 at 35 weeks recovered and had a normal vaginal birth of a 3070g boy at 38w + 4d. The baby had no signs of past or present infection with SARS-COV-2. The birth occurred at YouAn Hospital, Capital Medical University, Beijing, which has not previously reported cases in pregnancy, but the mother had been transferred from an unnamed hospital in Wuhan. Nevertheless we have included this as a non-duplicated case in summary totals. Citation: Xiali Xiong, Hong Wei, Zhihong Zhang, Jing Chang, Xiaopeng Ma, Xiang Gao, Qiang Chen, Qiumei Pang.

Study 33. US Centres for Disease Control reports 143 pregnant women
Preliminary data on lab-confirmed COVID-19 reported to CDC Feb 12–March 28, 2020. Of 7,162 cases, 143 were pregnant. Of these 72 stayed home, 31 hospitalised (non ICU), 4 entered ICU, and 36 had unknown hospitalisation status. “[…] for […] pregnancy, few severe outcomes were reported […].” Many probably reported elsewhere, so not added to running totals.

Study 32. 42 women from Lombardy
This pre-print Ferrazzi Lombardy ijgo.13162 cites a paper in press describing 42 pregnant women from Lombardy, Italy who had Covid-19 and delivered, 18 by Caesarean, and 24 vaginally. Two were spontaneously preterm. Seven women required CPAP or were admitted to ICU, but all “eventually did well”. No baby details are given. This is the first scientific report from Italy.

Study 30. 16 women with Covid-19 pneumonia from Hubei province
Sixteen pregnant women with confirmed COVID-19 pneumonia, and 18 with pneumonia on chest imaging who tested negative, were compared with two groups of control pregnancies (click here or ciaa352). The comparative design is similar to study 6a which, apart from an English abstract, has only been published in Chinese. However the hospital and authors differ, so I’m confident there is no overlap.

Study 29. ICNARC report 4 April 2020
This report from the UK Intensive Care National Audit & Research Centre (ICNARC) mentions two currently, and six recently (<6 weeks) pregnant women with Covid-19 who were also critically ill. One of the currently pregnant, and two of the recently pregnant women, were receiving advanced respiratory support. Excluded from running totals.
Study 28. Seven cases from Newark Beth Israel Medical Center. Newark, NJ
Pre-print from Am J Obstet Gynecol MFM (click here ) of two pregnant women with Covid-19 who developed cardiomyopathy. Report also mentions five other pregnant women with Covid-19 in Newark Beth Israel Medical Center. Details are only given for the two women with cardiomyopathy, and no baby details are given. For consistency of numbers I’ve assumed the other five pregnancies are ongoing in running totals.
Study 27. Expanded series from New York Presbyterian
This pre-print reports 43 pregnant women with COVID-19. It includes 36 new cases, identified during a period of universal testing, and 7 previously reported (Study 14) 43_COVID_040320. Click here.
No new scientific reports today. But obstetricians & midwives will enjoy reading the first newspaper report of a Covid-19 pregnancy and birth in France. Case 10 here. Better written and more detailed than many scientific reports.
Study 26 added. The first report of puerperal Covid-19. Not added to running totals.
Study 26. The first case report of puerperal COVID-19
This baby developed COVID-19 symptoms at age 10 days and was admitted to Wuhan Children’s Hospital age 17 days on February 5, 2020. Click here for the article in Chinese. What follows is based on Google translate. Both parents are reported to have had Covid-19 symptoms from three days before admission, i. e. day 14 after birth. This is therefore not a case of COVID infection in pregnancy or at birth, and therefore excluded from the running totals. However, the mother had puerperal Covid-19 and is, I believe, the first such case reported. The baby recovered and by implication, albeit not stated explicitly, so did the parents. The first author Zeng Lingkong shares a name with the first author of the series of 33 neonatal cases reported in JAMA Paediatrics, Study 8., but this is clearly not one of the three infected babies reported in that paper.

Annexe 6, page 32 of English version: “As opposed to Influenza A(H1N1)pdm09, pregnant women do not appear to be at higher risk of severe disease. In an investigation of 147 pregnant women (64 confirmed, 82 suspected and 1 asymptomatic), 8% had severe disease and 1% were critical.” Neither raw numbers, a citation, nor any further details are given. Assuming the percentages are of all 147, this would imply 12 women with severe disease, and one or two who were critical. In view of the high possibility of double counting – cases notified to the WHO team are likely to have also got reported elsewhere – I’ve left these out of the running total.

Study 23 Three cases from Iran
This review article (click here, full text here) from researchers from both Tehran and Shiraz in Iran, reports the births of three infants from infected mothers. The authors’ source was this Iranian ministry website (click here). All three babies were uninfected and survived, but two of the three mothers developed acute respiratory distress syndrome (ARDS) after delivery and died. Presumably this was related to their Covid-19 infection.

Study 17. Five from Maternal & Child Hospital of Hubei Province, Tongji Medical College
Two Caesarean and three vaginal births delivered in the Maternal and Child Hospital of Hubei Province, Tongji Medical College (click here). Or siyu chen. All mothers recovered. All babies well. According to Wikipaedia the MCH of HP is the 10th clinical college/hospital associated with Tongji Medical College. It is distinct from both Union hospital and Tongji hospital. These five births are therefore additional to those in the various Union Hospital reports, and to those in study 15. Citation: Chen S, Liao E, Shao Y.

Study 16. Three non-cases from Shenzhen 2nd People’s Hospital
Shenzen, a city of 13 million had had 420 confirmed cases of Covid-19, the second highest number outside Hubei, up to March 11th. Despite an annual birth rate in the city of 188,000, the 2nd People’s Hospital saw no COVID-19 infected pregnant women. Instead they report three suspected cases who, after barrier nursing, and in one case surgery for an ectopic pregnancy, were later confirmed negative.

Study 15. Seven cases from Tongji in Lancet Respiratory Med
These seven cases (click here) delivered at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology (Wuhan, China) between Jan 1 and Feb 8, 2020. All mothers had mild Covid-19 disease and all were delivered around term by Caesarean section. One baby (Patient 1) tested positive for Covid-19 by throat PCR at 36 hours and was transferred to Wuhan Children’s hospital. His mother’s age, gravidity, parity, lack of direct contact with Hunan seafood market and history of hypothyroidism all suggest this is the same mother/infant dyad as in report 11. Note however the reported birthweights differ 3250g v 3205g. No babies had any clinical symptoms and all (including the transferred one) were discharged home well. Wikipedia lists ten different hospitals/clinical colleges affiliated with Tongji Medical College in Wuhan. The 1st clinical college is called Wuhan Union Hospital. The 2nd clinical college is called Wuhan Tongji Hospital. This series is therefore unlikely to overlap with the various case series from Union Hospital Tongji.

Study 13. Cord blood serology from six babies in Zhongnan Hospital, Wuhan

Study 11. Caesarean birth & neonatal infection, Wuhan
Case report (click here) of a baby born by Caesarean to an infected mother at Wuhan Tongji Hospital. The baby was separated from the mother at birth but became infected (pharyngeal PCR at 36 hours). Both mother and baby recovered. I believe this case report is additional to the 33 Wuhan neonatal cases reported in JAMA, because the details (e.g. birth weight) do not align. This is therefore the fourth infected baby born by Caesarean.

Three more more primary scientific reports.
Study 9. A Caesarean birth from Zhejiang
This case report is in Chinese but has an English abstract. Click here. It’s from the First Affiliated Hospital, College of Medicine, Zhejiang University School of Medicine, Hangzhou. There appears to be no overlap of the authors with the Zhejiang Caesarean below, so this may be a new case. The Caesarean is reported as being “successful” which presumably means both mother and baby survived. Citation: Kang X, Zhang R, He H, Yao Y, Zheng Y, Wen X, Zhu S. Anesthesia management in cesarean section for a patient with coronavirus disease 2019. Zhejiang Da Xue Xue Bao Yi Xue Ban. 2020 May 25;49(1):0. Chinese. PMID: 32207592
Study 8. The 33 neonatal cases from Wuhan
A series of 33 neonates born to mothers who had Covid-19. All from Wuhan Children’s Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China. Reported in JAMA here. It seems possible that some or all of these infants are also included in the other Union Hospital Tongji series below. Of the 26 neonates delivered by Caesarean three became infected. One born at 30 weeks and 2 days developed RDS, pneumonia and suspected sepsis, and required non-invasive ventilation. The authors speculate that some of his problems were related to prematurity rather than COVID-19. The other two neonates were healthy. All three survived. By inference, although this is not specifically stated in the paper, none of the seven infant born vaginally became infected.

Assuming all the Union Hospital Tongji cases overlap, i.e. that Tongji has reported only 15 in total, there have been 38 published cases (39 babies) of Covid-19 infection in pregnancy. There have been no reports in the scientific literature of any maternal deaths, and all neonates have survived and not been infected. Four neonates remain undelivered.
David A Schwarz (click here) in a review in Arch Pathol (preprint available March 21st) also makes the total 38 published cases. However he includes a series published only in Chinese (his reference 17) Zhang I, Jiang Y, Wei M, Cheng BH, Zhou XC, Li J, et al. 湖北地区新型冠状病毒肺炎流行期间孕妇的 384 妊娠结局分析 [Analysis of the Pregnancy Outcomes in Pregnant Women With COVID-19 in Hubei Province]. Zhonghua Fu Chan Ke Za Zhi . 2020;55(0), E009. Accessed and translated 12 March 2020. He reports this as including 16 cases. For the moment I’ve not included this Hubei series, (but see Study 6a added 1 April).
Study 6a. 16 cases from Remnin
The cases included by David Schwarz on March 21 (see note above). English abstract (click here). Full text in Chinese here. Google translate used.
