After the first reports in South Africa, about a month later the Omicron variant of the coronavirus is already present in at least 70 countries and continues to spread rapidly, infecting thousands of people.
This variant is contributing to a new wave of infections in Europe, particularly in the UK and Denmark.
In just a few weeks, Omicron has significantly reversed the pandemic trend and consequently could influence the strategies pursued so far by the governments of various countries, which had relied heavily on vaccines in order to avoid the return of restrictive measures.
Over the weekend, the Netherlands entered a new deadlock, while several other governments have decided on other forms of closure and restrictions, but are also analyzing the approach to slow Omicron’s spread speed.
Following a wave of the Delta variant in the summer season, a new wave of infections with the Omicron variant in the winter season can create serious consequences especially for health systems.
The most pessimistic scenarios speak of a possible overload in intensive care units and all other hospital activities, comparable to those of the first months of 2020.
The risks posed by the new variant are in themselves higher, but may be mitigated in part by vaccination, which was lacking in the early stages of the pandemic.
Scientists have pointed out that Omicron may be the fastest-spreading variant to date, compared to other previous variants that appeared during the two years of the pandemic. Infection figures vary from country to country, but the differences are not so great.
