The new Covid-19 variant Omicron has been detected in several countries round the world, prompting measures such as travel restrictions and mask mandates. In some countries, these measures are quite strict. This new strain, first discovered in South Africa, is now present in the UK, in the Netherlands, Denmark, Belgium, Botswana, Germany, the Czech Republic, Australia, Hong Kong, Israel, and Italy. Since this new strain has over 30 mutations in its spike protein, it’s believed to be vaccine-resistant and prolong the almost two-year pandemic. Experts do not know yet if it will cause more of less severe Covid-19.
