Figure 4: Distribution and frequency of the most prevalent mutations of S protein of SARS-CoV-2 isolates circulated in India during the year 2020. D614G is predominant throughout the year with high frequency followed by L54F mutation. D614G, Q677H and P681H mutations originated during the first half of the year and their appearance was observed throughout the year; L54F, K77M and P812 L mutations emerged during the first half of the year but absent after few months of their appearance
