The Delta Plus variant of Covid-19 has a greater affinity towards lung issues as compared to other strains, National Technical Advisory Group on Immunisation (NTAGI) head Dr NK Arora has said, but it does not mean that it can cause severe lung disease or has higher transmissibility, he has clarified.
which was identified on June 11 was recently classified as a variant of concern by the Union health ministry on Tuesday. India has detected 51 cases of Delta Plus across 12 states with Maharashtra reporting maximum cases. “Delta plus is having greater affinity to mucosal lining in the lungs, higher compared to other variants, but if it causes damage or not is not clear yet. It also does not mean that this variant will cause more severe disease or it is more transmissible,” Dr Arora was quoted as saying by news agency PTI. He also pointed out that the disease is generally mild in all those who have vaccinated with either a single or double dose of the Covid-19 vaccine.
Arora said that the number of identified cases of Delta plus variant could be higher as asymptomatic individuals with Covid-19 may be spreading the virus. He highlighted that there is a need to keep a very close watch on the spread to understand the transmission efficiency.
He said that it is important to note that the genomic surveillance component has picked up at the right time and early enough. Since the government has identified the variant of concern, it means that states can now take action based on data shared with them. State governments can make micro plans for districts where the virus has been identified in order to contain its spread.
Union health secretary Rajesh Bhushan has already written to chief secretaries of 7 states and a Union Territory on Friday sharing the names of districts where cases of Delta Plus variant has been found and asked them to initiate widespread testing, prompt tracing as well as vaccine coverage on a priority basis.
