What is Delta Plus Variant?
World Health Organisation, last month, tagged B.1.617.2 strain as the ‘Delta’ variant of SARS-CoV-2. Now, the “Delta” variant has further mutated to form the ‘Delta plus’ or ‘AY.1’ variant. Well, according to the reports, the initial data suggests that the Delta plus variant shows signs of resistance against the monoclonal antibody cocktail treatment. This treatment for Covid-19 was recently authorised by the Central Drugs Standard Control Organisation (CDSCO).

3 Key Characteristics of Delta Plus Variant in India to Watch Out For
The health ministry has identified three characteristics of the Delta Plus variant:
- Increased transmissibility
- Stronger binding to receptors of lung cells
- Potential reduction in monoclonal antibody response
The chief secretaries of all the three states have been advised to take up immediate containment measures in the districts and clusters, including preventing crowds and intermingling of people, widespread testing, prompt tracing as well as vaccine coverage on a priority basis.
Furthermore, the health ministry also said that India is among the nine countries where the Delta Plus variant has been detected. It said that the variant has been detected in the US, UK, Portugal, Switzerland, Japan, Poland, Nepal, China and Russia.
Notably, the clusters of the variant has been identified by the Indian SARS-CoV-2 Genomics Consortium or INSACOG. The government has advised the states that their samples are sent to designated laboratories of INSACOG so that it can provide guidance based on the clinical epidemiological correlations.
So far, 22 cases of the Delta Plus variant of the coronavirus have been detected in India, with 16 of them being reported from Maharashtra and the remaining from Madhya Pradesh and Kerala, according to the government.
