The Delta variant spreads around the world
The Delta variant of the Coronavirus, formerly Indian and whose scientific name is B.1.617.2, it is fast spreading all over the world. A situation that is worrying public health experts because this variant is much more contagious of the Alpha variant, formerly English (B.1.1.7), which in turn was more contagious than the previous variants widespread in Europe. Furthermore, a single dose of the vaccine is not enough to counteract it.
The Delta variant is destined to become the prevailing one, as has already happened in UK, where despite the continuous increase in infections, the government of Boris Johnson has confirmed for July 19 the latest reopening with the abolition of the obligations of the mask indoors and the distance. The measures were initially scheduled for June 21 and then postponed.
The country is betting everything on vaccination. The increase from new infections, in fact, did not lead to the corresponding increase in hospitalizations and deaths as in previous waves. Thanks to vaccines, whose main objective has always been to reduce the impact of the disease. However, hospitalizations and deaths are also on the rise in the UK, albeit by few. A circumstance that worries the country’s experts who have criticized Johnson’s decision to remove the obligation to wear a mask indoors and on public transport and that of distancing. These are risky and too early measures also because a large part of the population has not yet completed vaccination.

However, we must not let our guard down on the spread of the virus, whose infections are on the rise all over the world, except the Americas. The last week they happened 2.6 million new cases. A situation that will have serious consequences on those large portions of the world population still without vaccination protection.
Compared to the previous week, in Europe you register a 30% increase in the incidence of infectionsinstead in Africa a 23% increase in mortality. In all WHO regions, except the Americas and Southeast Asia, there is a increase in the number of deaths in the last week.
