Few doubts about the future. The World Health Organization (WHO) confirmed this Wednesday the projections already advanced by several countries including France concerning the evolution of the Delta variant. According to the WHO, this very contagious strain of Covid-19 and already the source of more than three quarters of new cases of Covid in many large countries, will soon be predominant. “It (the Delta variant) is expected to quickly supplant other variants and to become the dominant lineage (of the Covid) in circulation in the coming months,” the UN agency said.

This variant, which was first detected in India, is now present in 124 countries and territories, 13 more than last week, compared to 180 (six more) for the Alpha, unearthed in the United Kingdom. , 130 (seven more) for Beta, identified for the first time in South Africa, and 78 (three more) for Gamma, which appeared in Brazil, underlined the WHO, whose headquarters are in Geneva.

The relaxation of public health measures in question

Among the countries where the Delta variant is now the cause of more than 75% of new cases are India, China, Russia, Indonesia, Australia, Bangladesh, United Kingdom, l ‘South Africa, Australia, Portugal and Israel. “However, we still do not know what is the exact mechanism” 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. “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.
