The Delta variant causes more than 75% of new cases
It is expected that it (the Delta variant) will quickly supplant the other variants and become the dominant lineage (of the Covid) in circulation in the coming months
", continued this UN agency headquartered in Geneva . Among the countries where the Delta variant is now the cause of more than 75% of new cases of this disease, we find India, China, Russia, Indonesia, Australia, Bangladesh, United Kingdom United, South Africa, Australia, Portugal and Israel.

" at the origin of the greater transmissibility "of this variant compared to others, recognized the WHO.
About 3.4 million additional cases of Covid were identified during the week of July 12 to 18, 12% more than the previous week, she said.
57,000 deaths from Covid per week
At this rate, the cumulative number of reported cases (since the start of the pandemic) worldwide is expected to exceed 200 million in the next three weeks,
" the WHO warned.
This explains this trend by four factors: more transmissible variants, a relaxation in public health measures, stronger social interaction and the fact that many people are not vaccinated.
