Five million left the city before it was closed off, but the city was swollen with people visiting for the Lunar New Year, and 9 million remain.

Regardless, the lockdown's effect is noticeable from above.

Wuhan looks like a ghost town.

Since January 23, the city of 11 million has been on lockdown. The Chinese government closed off Wuhan to try and stop the novel coronavirus, or 2019-nCoV, from spreading.

The coronavirus is thought to have originated at a wet market within the city. As of Thursday, it had killed 170 people, and infected at least 7,900 worldwide.

Five million people left before the lockdown, and and an estimated 9 million people were in the city once the quarantine started.

Despite this, satellite photos show a city without traffic. Typically congested streets and train stations are empty. Hotel lobbies are without patrons.

Photos on the ground show a few people still brave enough to venture out. But for the most part, nothing is going on.

Here's what life in Wuhan looks like under quarantine.
