A new variant of corona which is more infectious is wreaking havoc in the UK. The new strain of  Covid-19  now reached to other countries. According to the World Health Organization have spread rapidly across dozens of countries.

WHO said the more contagious Covid-19 known as VOC 202012/01 or B.1.1.7  variant first spotted in Britain had by January 25 spread to 70 countries across all regions of the world. It has been proven to transmit more easily than previous variants of the virus, had thus spread to 10 more countries over the past week. The organization has urged countries to actively work to spot mutations that might significantly alter either the virus's virulence or transmissibility.

Recently, British Prime Minister Boris Johnson last week also warned that fresh studies had indicated the new could be more deadly. Reacting to the statement,  WHO on Wednesday said that those "results are preliminary, and more analyses are required to further corroborate these findings". All viruses mutate when they replicate in order to adapt to their environment, and scientists have tracked multiple mutations of Sars-CoV-2, the virus that causes Covid-19.
