What are the differences between the Delta variant and the Delta Plus of Covid-19?


These days we are hearing about the Delta Plus variant of the Covid-19, but what is the difference with the Delta (ancient India)? Apparently it is a new, more infectious mutation of the coronavirus, which comes from the Delta, and which at the moment includes more than 40 cases, all located in India.

Specifically, this variant, which is not yet known if it is more dangerous than the previous one, worries the scientific community in case it extends like the Delta through different countries of the world.

For now and according to agencies, Collecting Data from Indian Health Minister Harsh Vardhan has been seen in Maharashtra (west), Kerala (south) and Madhya Pradesh (center) of the country.

Although it is being studied if it is more contagious, what it does know is that the Delta Plus variant has greater transmission capacity and this is what makes it stronger and generates this concern among experts.

In addition, the country’s health officials have reported that it is potentially resistant to the monoclonal antibody cocktail drugs, Casirivimab and Imdevimab, which have been shown to be highly effective with mild and moderate patients with Covid-19.

The virus mutates, we are seeing it, and it will try escape any protection we have to end him. In this case, the Delta Plus variant is based on the mutation of the spike protein, called K417N, and is studying whether it can escape the immunity of vaccines, which are currently serving to stop infections in much of the world.

In the event that this is not the case, health workers are already predicting new waves due to these new variants. The most important thing is to detect them in time so that infected people can be isolated and that they do not cross borders. But this is complicated as it is being seen with the different variants that have emerged because they are present in different countries.

The Reuters agency announces that, in addition to India, this new variant could also be in the United Kingdom, the United States and Japan.

As we have pointed out, it is not known exactly whether this new mutation is more or less resistant to vaccines. What is known is that with the Delta, one dose of both AstraZeneca and Pfizer vaccines, the effectiveness is 32%, and with two doses, the effectiveness of AstraZeneca increases up to 60% and that of Pfizer, up to 88% to the variant.
