Abstract

Objective: To study clinical presentation, disease severity, pregnancy complications, and maternal outcomes in women affected with coronavirus disease 2019 (COVID-19) during the third wave compared with the first and second waves of COVID-19.

Methods: A retrospective, observational cohort study was conducted among 2058 pregnant and postpartum women with COVID-19 admitted during three wave periods at a tertiary care COVID-19-dedicated hospital.

Results: The number of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) -infected pregnant and postpartum women with symptoms of COVID-19 was four times higher during the third wave compared with the first (odds ratio [OR] 4.6, 95% confidence interval [CI] 3.5-6.0, P < 0.001). There was a significantly lower proportion of pregnant and postpartum women with moderate to severe COVID-19 during the third wave (0.6%, 2/318) compared with those during the first wave (2.4%, 27/1143, P < 0.001) and second wave (14.4%, 86/597, P < 0.001). The intensive care/high dependency unit admissions during the third wave were significantly lower (2.5%, 8/318) than during the second wave (14.7%, 88/597; OR 0.2, 95% CI 0.1-0.3, P < 0.001) but similar to the first wave (2.4%, 27/1143).

Conclusions: Decreased severity of COVID-19, reduced maternal mortality, and morbidity were reported in the third wave compared with the first wave and second wave of COVID-19 in the Mumbai Metropolitan Region, India.

Trial registration: The study is registered with the Clinical Trial Registry of India (Registration no: CTRI/2020/05/025423).
