As the world reopens after 18-20 months of the Covid-19 pandemic and lockdowns, a new variant of the coronavirus -- called B.1.1.529 -- has been identified in South Africa

As the world reopens after 18-20 months of the Covid-19 pandemic and lockdowns, a new variant of the coronavirus -- called B.1.1.529 -- has been identified in South Africa that has left the scientific community worried, as they fear that this new strain could fuel outbreaks in several countries and cripple health systems once again. Over 100 cases have been detected in South Africa, where the new strain is slowly becoming the dominant one.

Here are five things you should know about this deadly super Covid variant that has forced a number of countries, including the UK, Israel, Italy and Singapore, to restrict travel from South Africa and other countries in the region.

1. According to South African health officials, the 'B.1.1.529' variant has many more mutations than scientists expected, especially after a severe third wave, which was driven by the Delta variant. Many of the mutations are of concern for immune evasion and transmissibility.

2. B.1.1.529 carries a high number of mutations in its spike protein, which plays a key role in the virus' entry into cells in the human body. The B.1.1.529 variant has 50 mutations overall, including more than 30 on the spike protein alone which is the target of most current Covid vaccines.
