Coronavirus figures released by health authorities across South America on Monday show a number of countries grappling with a spike in infections and deaths.

Uruguay and Paraguay registered record numbers of daily deaths, while the total number of covid cases surpassed the 13 million mark in Brazil. The surge has been attributed to the spread of the Brazil variant.

The variant is thought to be more than twice as transmissible as the original. Brazilian public health institute says, it has detected 92 variants of coronavirus in the country. Experts say that the development of new variants is not surprising, all viruses mutate as they make copies of themselves to spread.

It has mutations on the spike protein, that part of the virus which attaches to human cells and it is these mutations which are thought to make it more transmissible.
