Right now, more than a billion people around the world are living a very different life to usual. Social distancing and self-isolation measures have transformed our cities. Bars, restaurants and cultural venues have been shuttered. Public transport is suspended or reduced. Many institutions are closed to the public (though you can still tour some major landmarks online). In some countries, even going for a stroll requires official permission.
The result, in dozens of the world’s greatest cities, is a city that looks, sounds and even tastes very different to usual. Check out these striking images of empty streets and other usually busy places around the world, and get a glimpse into what happens when the human world suddenly becomes human-free.
More than nine million people live in London, but you wouldn't know it by looking at the UK capital right now: normally crowded places like Piccadilly Circus (pictured) are empty following a compulsory lockdown order.
