Ahmedabad: Gujarat has witnessed a four-fold rise in fortnightly Covid cases from 529 in May 21 to June 4 to 2,249 during June 5 to 19. The state has also recorded a 114-day high daily tally of 244 on Sunday. Experts say the spike could be a result of Omicron’s sub-variant BA.2.38.

According to data from Gujarat Biotechnology Research Centre (GBRC), the past month witnessed whole genomic sequencing of 431 samples from Covid patients. Of the total, 223 or 52% were found to be BA.2.38. 

Despite recent spike, few takers for booster doses.

The BA.2.38 variant was first reported in the state in May and gained dominance in June. Till May, BA.2 – the dominant variant in India and many countries in the world – reigned in the state and in the past one month’s data, it accounted for 145 or 34% share in sequencing.
