The Delta variant of Covid-19 remains the current dominant strain in 185 countries as per the WHO.

Delta now accounts for 90 per cent of the sequences submitted to GISAID with a sample collection, said WHO.

GISAID (Global Initiative on Sharing Avian Influenza Data) is an open-access database.

Since less than one per cent each of Alpha, Beta and Gamma variants are currently circulating.

Scientists believe that the Delta variant is more transmissible and it is also replacing the other viruses that are circulating.

Also, the global health body has revised the classification of Eta (detected in 81 countries), Iota (identified in at least 49 countries) and Kappa (spread to 57 countries) from variants of interest (VOI) to Variants Under Monitoring. This is due to their substantial decline in the incidence worldwide.

The Delta variant spreads faster, it has infected both the unvaccinated and fully vaccinated populations in a federal prison in Texas, as per a report from the US Centers for Disease Control and Prevention.

In the context of India, the recent decline in Covid cases can be well attributed to lower Covid-19 testing and speedy vaccination drive.

According to ICMR data, 15,92,395 tests were conducted in 24 hours.

On average, around 15 lakh tests are getting conducted across India each day for the past 10 days.

Moreover, Kerala also saw improvement in its coronavirus caseload. There has been a decline of 5,813 active cases in a day.

When it comes to R-values of Maharashtra and Kerala these remain below 1. Furthermore, India’s daily positivity rate was recorded at 1.69 per cent.
