International tourism could shrink by a whopping 60-80 per cent in 2020 due to the COVID-19 pandemic, resulting in the revenue loss of $910 billion to $1.2 trillion and placing millions of livelihoods at risk, said the World Tourism Organisation (UNWTO).

The pandemic, spread across every country on the planet, has so far infected 4.1 million people and killed 2,82,719 people. The US has been the worst-affected. The global international agency said the pandemic has already caused a 22 per cent fall in international tourist arrivals during the first quarter of 2020.
