Delta
The Delta variation was first seen in India’s Maharashtra state in 2021, during a big wave of Covid-19 cases. After this variant arrived in the United Kingdom, it started to spread quickly. After some studies, scientists determined that Delta was approximately 60% more transmissible than Alpha, the previous variant.
According to some studies from Wendy Barclay’s laboratory, a virologist at Imperial College London, it had been found that Delta is able to multiply and infect people so much faster than other variants. That is because this variation has higher levels in the airways of infected patients, which is probably going to outpace the initial responses against SARS-CoV-2.
Knowing that it’s happening all over the world, we can say that the Delta variant is responsible for thousands of deaths and infection cases.
