TheDelta variantor B.1.617.2 strain, which was first detected in India, is more infectious than the Alpha variant or B.1.1.7, first detected in the United Kingdom, and is also the reason behind the second wave of the Covid-19 pandemic, reveals a study conducted by a team of scientists from different Indian institutions.
The scientists noted B.1.617.2 is capable of creating very fast-rising outbreaks, importantly with vaccination breakthroughs (infections after vaccination). We would re-emphasise that prior infections, high seropositivity and partial vaccination are insufficient impediments to its spread, as seen in Delhi, and strong public Health response will be needed globally for its containment
