A new type of Covid-19 subvariant named AY.4, a mutation of Delta variant, has been detected in Indore, India. At least seven people were detected with the new AY.4 mutation in the city.
The National Center for Disease Control (NCDC) of India has detected the new subvariant in seven samples by genome sequencing, the Times of India reported.
BS Satia, chief medical and health officer of Indore, said the samples were collected in September. Among the victims were two army officers. Besides, AY.4 subvariant was detected in 1% of the samples from Maharashtra.
The NCDC report said this type of Delta was behind the upward COVID infection in Indore in September – where 64 percent more patients were detected than in August. 44 Army officers training at Army College were tested COVID positive. Authorities then sent their samples for genome sequencing.
BS Satia said the NCDC released the reports of seven by October 1 and others by October 16.
In a new interpretation, Anita Mutha, head of the microbiology department at MGM College, told the Times of India that AY.4 is a subvariant of the Covid-19 Delta genus. “But it’s not Delta or Delta Plus,” he added.
The Times of India says it (AY.4 type) is now a “curious” type. Little is known about the potential for such an infection or the risk of developing a serious condition in an infected person. Besides, it is not certain whether it will have a groundbreaking effect on infection.
