A new mutant strain of the novel coronavirus found in the United Kingdom has led to a reinforcement of precautionary restrictions across the globe. Several countries, including India, have banned air travel to and from the UK. States in India have also enacted measures to prevent large gatherings as efforts continue to trace passengers who returned from the UK in recent days and their contacts. The restrictions will hit New Year's Eve celebrations in many parts, with several authorities announcing bans on New Year's parties.
