Title: COVID-19 pandemic dynamics in India and impact of the SARS-CoV-2 Delta (B.1.617.2) variant Cord-id: 0xnpfdt9 Document date: 2021_6_25
ID: 0xnpfdt9
Snippet: The Delta SARS-CoV-2 variant has spread quickly since first being identified. To better understand its epidemiological characteristics and impact, we utilize multiple datasets and comprehensive model-inference methods to reconstruct COVID-19 pandemic dynamics in India, where Delta first emerged. Using model-inference estimates from March 2020 to May 2021, we estimate the Delta variant can escape adaptive immunity induced by prior wildtype infection roughly half of the time and is around 60% more
Document: The Delta SARS-CoV-2 variant has spread quickly since first being identified. To better understand its epidemiological characteristics and impact, we utilize multiple datasets and comprehensive model-inference methods to reconstruct COVID-19 pandemic dynamics in India, where Delta first emerged. Using model-inference estimates from March 2020 to May 2021, we estimate the Delta variant can escape adaptive immunity induced by prior wildtype infection roughly half of the time and is around 60% more infectious than wildtype SARS-CoV-2. In addition, our analysis suggests that the recent case decline in India was likely due to implemented non-pharmaceutical interventions and weather conditions less conducive for SARS-CoV-2 transmission during March - May, rather than high population immunity. Model projections show infections could resurge as India enters its monsoon season, beginning June, if intervention measures are lifted prematurely.
