Conclusion
Coronavirus disease 2019 might increase the risk for pregnancy complications. In our study, more severe symptoms such as pneumonia and admission to ICU seem to be more common amongst Asian women, pregnancies with known comorbidities such as diabetes and pregnant women with confirmed COVID-19 infection in the 3rd trimester.
There is a relatively higher rate of preterm birth, preeclampsia, and caesarean in hospitalised mothers infected with COVID-19. There has been no clinical evidence of vertical transmission in our study or in published studies so far. The findings from this study can guide and enhance prenatal counselling of women with COVID-19 infection occurring during pregnancy and could potentially give guidance to prepare for the possible rebound of the epidemic, although should be interpreted with caution in view of the very small number of included cases. Furthermore, supplying health workers with appropriate PPE is essential to ensure they are equipped for a potential second wave of the infection, especially when reviewing COVID-19 patients in viral shedding period who were not investigated for the infection.
