Clinical Features and Outcomes of COVID-19 Infection among Pregnant Women in South Africa

Background and Objective: Studies among COVID positive pregnant women are limited. Previous studies reported high rate of symptoms, comorbidities and poor fetal/neonatal outcome among women of different ethnicity. To date, no study was reported among pregnant African women. This study was conducted to determine the clinical features and outcomes of COVID-19 positive pregnant women in Ekurhuleni District in South Africa. Methods: Retrospective record review of 103 COVID-19 infected pregnant women during the period of April to September 2020 was done. Clinical features, symptoms, comorbidities, laboratory results, maternal and neonatal outcomes were analyzed. Descriptive statistics (mean + standard deviation, number and percentages) and inferential statistics (Chi-square test) were calculated. Ethical clearance was obtained from the Human Research Ethics Committee of the University of Witwatersrand, South Africa. Results: Majority (90%) were of African ethnicity and symptomatic (53%). The commonest symptom, comorbidity and laboratory abnormality was cough (62%), hypertension (23%) and high LDH (20%), respectively. Thrombocytopenia and lymphocytopenia occurred among 9% and 15% of the women, respectively. Although association was not significant, symptoms were more common among comorbid, HIV positive and women with abnormal results. Commonest complications were preterm labor (8%) and macerated stillbirths (6%). Six (6%) mothers died. Conclusion and Global Health Implications: COVID positive pregnant South African women were commonly symptomatic but incidence of adverse fetal outcomes was low. High rate of preterm labor, macerated stillbirths and maternal deaths was a concern. This study has several strengths. It included all COVID positive women over a 6 months’ period at all level of healthcare facilities such as clinics, community health centers/midwifery units, and district, regional and tertiary hospitals, conducted in an African country. Previous studies included mainly hospitals raising a high probability of including mainly severely ill women. The study might benefit the health care workers in other African countries.
