Studies cited by WHO warn Delta variant has 137% more lethality

The World Health Organization (WHO) this week cited two new studies from China and Canada, not yet published in a trade journal, which warn of the greater danger of Delta variant of covid-19.

According to the Canadian study, the health risks of contracting Covid-19 with the variant Delta They are significantly higher than with the first types of coronavirus: the danger of having to go to the hospital increases by around 120%, and the danger of needing intensive care is around 287%. The risk of death is over 137%.

In addition, the viral load was 1,200 times higher on the first positive test than in the original variants of the virus. “This suggests that this disturbing variant may reproduce faster and be more contagious in the early stages of infection. “, said WHO as registered Euronews.

Globally, the number of new cases of coronavirus infection increased 12% to 3.4 million in the week to July 18. The highest number of new cases were recorded in Indonesia (over 44%) and the United Kingdom (over 41%).

The WHO predicts that the Delta variant – which already accounts for more than three-quarters of new Covid cases in many countries – will predominate in the coming months.

“It is expected that she (the Delta variant) will quickly supplant the other variants and become the dominant bloodline in circulation in the months to come.”, considered as the UN agency. And they added that “the exact mechanism behind the higher transmissibility” of this variant compared to others is still unknown.

Countries where the Delta variant causes more than 75% of new cases of the disease are India, China, Russia, Indonesia, Australia, Bangladesh, United Kingdom, South Africa, Australia, Portugal and Israel.

After being detected for the first time in India, it is now present in 124 countries and territories, 13 more than last week, compared to 180 (six more) of the Alpha variant, which was detected in the United Kingdom, 130 (seven more) from Beta, which was first identified in South Africa, and 78 (three more) from Gamma, which appeared in Brazil, according to new figures that the WHO is rebounding.
