The latest strain is Delta plus variant –which has been formed due to a mutation in the existing Delta or B.1.617.2 variant – the variant that originated in India. “Six hundred thousand-plus Americans have died, and with this delta variant you know there’s going to be others as well. You know it’s going to happen. We’ve got to get young people vaccinated,” US President Joe Biden said last week.
Delta is the most transmissible of the variants identified so far, has been identified in at least 85 countries, and is spreading rapidly among unvaccinated populations,” said De Tedros Adhanom Ghebreyesus, WHO’s Director General in his weekly briefing.
A lockdown mandates people to stay at home. So, with minimum interaction possible, the lockdown slows down the spread of a pandemic – and has been historically used as a control measure to combat pandemics.
