NEW DELHI -- Around 40 cases of the 'delta plus' strain -- a mutated version of the highly contagious delta variant that drove the much of the devastating second wave of the COVID-19 pandemic in India -- have been detected in the country, the health ministry said Wednesday, amid concerns over a possible resurgence of infections in the South Asian nation.
Three Indian states -- Maharashtra, Kerala and Madhya Pradesh, where the delta plus variant, also known as AY.1, has been observed sporadically -- have been advised to step up surveillance and undertake appropriate public health measures, the ministry said.
