From government clarifying on Aarogya Setu to Sputnik V's India trials, here are the top updates on coronavirus pandemic.

An RTI was filed to find out who built the Aarogya Setu app. Meanwhile, Sputnik V's India trial is likely to end in May next year. Delhi recorded highest number of cases in a single day crossing 5,000 daily cases. Also, a UK study shows that antibody responses to Covid may diminish over time. A small but growing number of recovered patients have fallen ill with Covid-19 again. Watch the full video for more details.
