More than 1 million people have died from coronavirus, after the deadly disease emerged less than a year ago and swept around the globe.
The pandemic has ravaged the world's economy, inflamed geopolitical tensions and upended lives, from Indian slums and Brazil's jungles to America's biggest city New York.
Sports, live entertainment and international travel ground to a halt as fans, audiences and tourists were forced to stay at home, kept inside by strict measures imposed to curb the virus's spread.
Drastic controls that put half of humanity - more than 4 billion people - under some form of lockdown by April at first slowed its pace, but since restrictions were eased cases have soared again.
The US has the highest death toll with more than 200,000 fatalities followed by Brazil, India, Mexico and Britain.
With scientists still racing to find a working vaccine, governments are again forced into an uneasy balancing act: Virus controls slow the spread of the disease, but they hurt already reeling economies and businesses.
The IMF earlier in 2020 warned that the economic upheaval could cause a "crisis like no other" as the world's GDP collapsed.
Europe, hit hard by the first wave, is now facing another surge in cases, with Paris, London and Madrid all forced to introduce controls to slow infections threatening to overload hospitals.
