The number of COVID-19 cases has once again started to increase in India. The seven-day average number of infections rose to 4,500 on June 8 from around 2,100 a fortnight ago. Much like the previous waves, Delhi, Mumbai, Chennai, and Bengaluru have recorded a large number of cases. Both Chennai and Mumbai have recorded a sharp spike in the number of hospitalisations. Data from GISAID show that Omicron’s BA.2 sub-lineage may be responsible for the uptick in most cities. However, in Chennai, the latest increase coincides with a noticeable rise in the BA.5 sub-lineage. But given the small number of cases sequenced in every district, the data have to be taken with a pinch of salt.
