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 281 – First report from the US PRIORITY Study
The PRIORITY study collected self-reported cases of Covid-19 in pregnancy. In this report they describe the outcomes of 179 infants born to mothers who had tested positive and 84 who tested negative. 82% of the former group and 63% of the latter had symptoms (click here or ciaa1411). 44 babies were admitted to NICU, and two were infected. Although not explicitly stated there appear to have been no stillbirths or neonatal deaths. Births occurred at over 100 hospitals across the US so it is likely that many will have been included in other US reports.

Study 271 – 86 “extra” maternal deaths during pandemic in Mexico
These authors used publicly available goverment statisitics (click here) to estimate the excess maternal deaths from Covid-19 in Mexico in 2020 (click here or Excess Maternal Deaths Associated With Coronavirus.97254). The predicted maternal mortality ratio was 29.5 per 100,000 live births, and so far in 2020 the actual ratio is 42.4. The excess was entirely confined to respiratory disease. Overall 86 “extra” deaths have ocurred. In comparison the 168 deaths officially reported as due to respiratory disease are made up of 109 deaths due to confirmed COVID-19, 34 for which COVID-19 needs to be confirmed, and 25 due to other respiratory diseases.

The patients are therefore likely to include some from previous Spanish series, namely studies 53, 125, 151, 158, 165, 185, 191, 196, 235, and 266. Note that study 196, authored by the Neo-COVID-19 Research Group, which includes 14 hospitals in Spain, reported 42 cases and included one maternal death, so presumably does not completely overlap.

Study 263 – 66 cases (plus one maternal death) from Tehran, Iran
Of 66 women with Covid-19 treated between March 1 to Sep 1, 2020, four were admitted to ICU but none required ventilation (click here or taaa158). Two women aborted, 43 delivered, and 21 pregnancies are ongoing. No baby outcomes are reported directly, although one baby tested positive. No women in the series died. However in the discusssion section it is mentioned that in February 2020, a 22-year-old pregnant woman with COVID-19 at 37 weeks had died in the same hospital. It is not clear if she had been included in studies 23, 66 or 67. The women were cared for in Arash Women’s Hospital, which has also reported a set of triplets of which one was infected with SARS-CoV-2 and survived, and the other two who were negative died, (case 5 in study 250). Those triplets seem not to be included in the present series although it is not clear why. Citation: Pirjani R, Hosseini R, Soori T, et al.

Study 235 – 125 anti-SARS-CoV-2 sero-positive women from Barcelona, Spain
Of 874 pregnant women attending first trimester screening (n=372) or delivery (n=502) from April 14 to May 5, 2020, 125 were positive for anti-SARS-CoV-2 IgG, IgM, or IgA. 54/372 in first trimester, and 71/502 in 3rd trimester (click here or PIIS0140673620317141 & supplementary material mmc1). Three women required oxygen therapy, but none critical care. No baby outcomes reported. Women were cared for in Hospital Sant Joan de Déu, Hospital Clínic, and Sant Pau all in Barcelona. They probably overlap with cases reported in studies 185 and 191, but probably not with those in studies 53, 125, 151, 158, 165, or 196.

Study 234 – 70 cases from New York
Of 675 pregnant women admitted for delivery and tested for SARS-CoV-2, 70 were positive, of whom 55 were asymptomatic on presentation (click here or 1471-0528.16403). Three mothers were hypoxic, one was admitted to ITU but none required ventilation. No mothers died. There was one stillbirth to a mother with asymptomatic Covid-19 and other pathology. 73 babies were born, 71 were tested and all were negative. The three hospitals, all affiliated with New York Presbyterian were Weill Cornell Medical Center, Queens, and Lower Manhattan Hospital. The cases may therefore also have been included in studies 160, 216 and 230. However, they were probably not included in the other NY Presbyterian series namely studies 14, 27, 41, 95, 96 and 136.

Study 233 – case report from Marrakech, Morocco
A woman contracted Covid-19 at 31 weeks gestation, required oxygen therapy and went into premature labour. A Caesarean was performed for fetal distress (click here or 8852816). The mother recovered. The baby tested negative but had severe birth asphyxia and died age 5 days. The mother was cared for at University Hospital of Mohammed VI, Marrakech, which has not previously reported cases. This is the first report from Morocco.

Study 232 – 44 cases from Boston, Massachusetts
Of 44 pregnant or recently postpartum women with COVID-19, 5 had severe disease and 2 required ventilation (click here or ijgo.13333). All mothers survived. Of 11 babies born, 9 tested negative and 2 declined testing. All survived. 31 pregnancies are ongoing. The majority of patients belonged to racial [sic] or ethnic minority groups. From author affiliations the unnamed hospital was probably Brigham and Women’s Hospital, Boston. Some cases may therefore have been reported in study 231, but probably differ from those in studies 129 & 142. Citation: Onwuzurike, C., Diouf, K., Meadows, A.R. and Nour, N.M.

Study 231 – 19 placentas from Boston, Massachusetts
2/19 placentas of affected pregnancies tested positive for SARS-CoV-2 by in-situ hybrization (click here or s41379-020-0639-4). There were no specific pathologic features compared with 262 control placentas. One fetus was stillborn at 22 weeks and not tested. There were two sets of twins. All liveborn babies survived, and only one tested positive. From the case codes in Table 2 it appears that 10 pregnancies had been cared for at Massachusetts General Hospital, 4 at Brigham and Women’s Hospital & 5 at Beth Israel Deaconess Medical Center. Some have therefore probably been reported in studies 129 & 142. Citation: Hecht, J.L., Quade, B., Deshpande, V. et al.

Study 230 – Placental features of 74 cases from New York
2/53 placentas from affected pregnancies contained a SARS-CoV-2 viral signal by in-situ hybridization (click here or Zhang, Placenta, AJOGMFM). One baby tested positive, the other negative. Both were asymptomatic. There were no specific histological differences between 74 placentas from SARS-CoV-2 positive pregnancies and 290 controls. The authors are affiliated with the New York Presbyterian, Brooklyn Methodist, Weill Cornell group of hospitals so the clinical aspects of the cases have probably been reported before.

Study 229 – Some assisted reproduction pregnancies during the pandemic in France
The authors report 88, or possibly 104, women (numbers are unclear) who conceived by assisted reproduction between December 2019 & March 2020, and were still pregnant after the first reported case of Covid-19 in France on 12th February. Ten had symptoms related to Covid-19, none severe or requiring intensive care (click here or PIIS0301211520304929). Five of the ten were tested and two were positive. 15 women miscarried although their Covid-19 status was not reported. From author affiliations the unnamed centre was probably the Reproductive Biology Unit, Antoine Béclère Hospital, Clamart, France. These cases may therefore feature in studies 150, 157, 184 & 217. The pregnancies were unlikely to have been sufficiently far advanced to have featured in studies 48 & 187.

Study 228 – Case report from Stockton, California
A pregnant woman contracted severe Covid-19 requiring ventilation at 32 weeks (click here or Ching Case Rep RespMed). She was delivered by Caesarean section for suspected placenta praevia and recovered. The baby required intubation and ventilation for 48 hours but tested negative. The ultimate baby outcome is not reported. The hospital is unnamed but the authors’ affiliation with San Joaquin Critical Care Medical Group, suggests that it was San Joaquin General Hospital in Stockton, California which has not previously reported cases.

Study 227 – Case report from Columbia, Missouri, USA
A woman with mild Covid-19 gave birth to a male infant vaginally at term (click here or HSU jmv.26386). She recovered. The baby breast fed, tested negative and was fine. The virus was demonstrated in the placenta by immuno-histochemistry using a SARS-CoV-2 nucleocapsid-specific monoclonal antibody. Mother and baby were cared for at University of Missouri Women and Children’s Hospital which has not previously reported cases. The clinical details of case 69 differ.

Study 226 – 3 cases treated with remdesivir from Stanford
Three pregnant women with Covid-19 were treated with remdesivir outside a clinical trial (click here or PIIS0002937820308292). One developed “transaminitis” – I think the authors mean raised liver transaminase. The pre-print is missing a table – which the authors attributed to the remdesivir. That woman later developed intrahepatic cholestasis of pregnancy and delivered normally. The other pregnancies are ongoing. The acknowledgements suggest that the unnamed hospital is Lucile Packard Children’s Hospital at Stanford. Although one author is shared with study 115 from another unnamed Stanford hospital, the clinical details differ. These cases have probably not previously been reported.

Study 225 – over 600 cases (412 births) in Nair Hospital, Mumbai
Nair hospital, Mumbai, India, a dedicated Covid-19 facility, has cared for over 600 pregnant women with the disease (click here or ijgo.13338). There have been 412 births including seven pairs of twins and one set of triplets. No mothers died of Covid-19 directly, although four died of other causes. No baby outcomes reported. The first two cases had originally been cared for elsewhere, and also previously denied admission at four private hospitals, the latter a feature of news reports from India (click here). Two health care workers contracted COVID-19. Nair Hospital has not previously reported cases. The case reported in study 58 was from New Delhi.

Study 201 – 20 maternal deaths from Brazil
Twenty COVID-19 related maternal deaths were identified from the Brazilian Ministry of Health surveillance system (click here or Takemoto Maternal mortality and COVID 19). Ten were in the Northeast region, and nine in the Southeast (5 in São Paulo). They probably overlap with those in studies 138, 182 & 194. Citation: Maira L. S. Takemoto , Mariane O.

Study 200 – 23 cases from Birmingham, UK
Of 23 pregnant women with COVID-19, four were admitted to ITU and one died from basilar artery thrombosis, pulmonary embolism, and diabetic ketoacidosis (click here or Antoun EJOG 1-s2.0-S0301211520304486-main). 20 babies were delivered, incl. one set of twins. All survived. Seven babies were tested for SARS-CoV-2 and all were negative. The hospital is unnamed but from its size and author affiliations is likely to be Birmingham Women’s Hospital which has not previously reported cases. However, they will have been included in the UKOSS report study 92. The clinical details of the maternal death suggest this is the same patient as reported in study 107 as having been delivered at Birmingham Heartlands Hospital.

Study 199 – case report of a miscarriage from France
A woman with Covid-19 miscarried at 20 weeks (click here or Hachem EJOG 1-s2.0-S0301211520304668-main). The hospital is unnamed but from author affiliation is René Dubos Hospital, Cergy-Pontoise, a northern suburb of Paris. No authors with this affiliation were included in the GROG series, study 150, so this case has probably not been reported before.

Study 198 – 10 cases from Cleveland, Ohio
Ten pregnant women tested positive for SARS-CoV-2, of whom three were symptomatic (click here or Berkowitz AJOG PIIS0002937820307298). None required medical treatment beyond standard obstetric care. They were cared for at various hospitals managed by the Cleveland Clinic Foundation in Ohio, which appear to be all based around the town of Cleveland itself. If so they have not previously been reported. Citation: Berkowitz KM, Goje O, Eaton J. Implementation of universal testing for SARS-CoV-2 in pregnant women with intended admission for delivery.

Study 197 – A case report from Mantova, Italy
A pregnant woman with Covid-19 at 24 weeks gestation was treated with convalescent plasma (click here or Grisolia AJOG MFM 1-s2.0-S258993332030118X-main). The following day her condition worsened, and she was transferred to ICU where she received non-invasive ventilation. After a 2nd dose of convalescent plasma she recovered. The pregnancy is ongoing. The hospital is not named but from author affiliations was Carlo Poma Hospital, Mantova. Mantova is in Lombardy so this case was probably included in studies 32 & 64.

Study 195 – 14 first trimester cases from Turin
14 women tested positive for SARS-CoV-2 in the first trimester (click here or cosma turin jmv.26267). No outcomes reported. They were cared for at Sant’ Anna Hospital, Turin, Italy, so are likely included in the 23 first trimester cases in study 167.

Study 194 – Three cases from Vitoria, Espirito Santo State. Brazil
Two women with severe Covid-19 in pregnancy, and one with severe disease postnatally, required prologed ICU admission and ventilation (click here or dos Reis Case Rep Brazil). One mother died. All three babies tested negative and survived. This is the first scientific report from this city. However, the woman who died may be included in studies 66, 138 & 182.

Study 193 – Case report from Belgium
A pregnant woman with twins developed mild Covid-19 at 22 weeks gestion (click here or Pulinx 10096_2020_Article_3964). She was nursed at home, but at 24 weeks went into spontanous labour. One twin was stillborn and the other died soon after birth. Amniotic fluid and placental tissue tested positive for SARS-CoV-2. 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.

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 188 – Four, possibly five, cases from Bergamo, Italy
Four pregnant women with Covid-19 and a further woman who had possible pneumonia one day after delivering twins and two months later had SARS-CoV-2 IgG antbodies, are reported (click here or 1-s2.0-S0014256520301120-main (002)) All mothers and babies survived although one of the four definite Covid-19 mothers developed Guillain-Barré syndrome and remains in hospital. All patients were cared for Bolognini Hospital which is a “spoke center” for COVID 19 in pregnancy in Seriate, Bergamo in Lombardy. It is thus likely that they were included in studies 32, 64 & 117.

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 165 – 65 cases from Madrid
Of 65 women with Covid-19, 13 were diagnosed postnatally. Of the 52 antenatal cases, 32 developed pneumonia and two required ICU admission (click here or PIIS2589537020301516. No mother died. 6/32 women with pneumonia had delivered and no babies were infected. Patients were cared for at University Hospital “12 de Octubre”.

Study 161 – 54 cases from Strasbourg
Of 54 pregnant women with confirmed (n=38) or suspected (n=16) COVID-19 in pregnancy treated at Strasbourg University Hospital (France) from March 1 to April 3, there was one miscarriage, 21 live births (12 vaginal, 9 cesarean), and 32 ongoing pregnancies (click here or PIIS0002937820306396). Five women were admitted to ICU, three required mechanical ventilation and one ECMO. No mothers died, although at the time of writing the woman on ECMO remained on it. All babies tested negative & none died. Strasbourg doctors co-authored the GROG report, so these cases are probably included in study 150.

Study 160 – 241 cases from New York
Of 241 pregnant women with laboratory-confirmed SARSCoV-2 infection who gave birth between March 13 & April 12, there were 245 live births to 241 women (6 sets of twins), & 2 stillbirths (click here or Characteristics and_Outcomes of 241 Births to.97310). 17 women were admitted to ITU and 9 intubated. No mothers died, although one woman remained intubated at time of writing. 27% of neonates were admitted to NICU. Of liveborns with SARS-CoV-2 test results 236/230 tested negative. No further neonatal outcomes reported. The five hospitals were “Montefiore Medical Center; Mount Sinai Health System, including Mount Sinai Hospital and Mount Sinai West; its affiliate, NYC Health and Hospitals- Elmhurst Hospital; NewYork-Presbyterian Hospital- Columbia University; and New York University Langone Health, including NYU Langone Hospitals, Manhattan campus, and NYU Langone Hospitals-Brooklyn”. These cases therefore likely overlap with studies 14, 27, 41, 49, 83, 85, 86, 95, 95, 119, 135, 136, & 152. They probably do not overlap with women in studies 61, 113, 118, 122 & 134, which included women cared for in different New York centres. Women in Study 99 are unclear.

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 clinical details and patient age indicate that this is not patient no. 42 (click here) reported in the Ohio newspapers.

Studies 44 & 45 added. HT @Belinda_J_Lowe for study 45. We’ve also done some housekeeping today. Study 13 probably overlaps with study 1, so 13 has been removed from running totals. Study 3 includes 13 patients from multiple centres, both in and outside Hubei province, who may overlap with other studies. 12 mothers (3 undelivered) and 9 babies therefore removed from the running total. Only case 6, where the woman was reported to be on ECMO and the baby stillborn and preterm, does not appear to have been reported elsewhere, so remains in the running totals.

They presumably include the 18 women with Covid-19 previously reported as having delivered in the same two hospitals (Studies 14 & 27), as well as some of the women who were at the time undelivered in those two series.

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.

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).

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.

Assuming the percentages are of all 147, this would imply 12 women with severe disease, and one or two who were critical.

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.

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.

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.

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).

This is therefore the fourth infected baby born by Caesarean.

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.

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).
