From Wuhan to New York City: A timeline of COVID-19's spread
COVID-19 has spread quickly around the world, causing more than 636,000 deaths and infecting more than 15 million people as of July 24, according to Johns Hopkins' Coronavirus Resource Center. It’s already hard to remember life before COVID-19—but it was just half a year ago when a doctor in China sounded the alarm about a new respiratory virus. Since then, cases have been confirmed in nearly every country and on every continent except Antarctica. The United States today has the most COVID-19 cases in the world.
The story of how COVID-19 spread so far and so fast is a story of government secrecy, delayed action, and a highly contagious disease we haven’t seen before. To better understand what has happened and what might follow, Stacker constructed a timeline of the COVID-19 pandemic from its first mention by Dr. Li Wenliang in Wuhan, China. The situation changes daily, but what is clear is that this virus is still spreading and that the surest way to flatten the curve is to keep people apart through social distancing.
Our timeline includes information from a range of sources including news outlets such as the New York Times and CNN, science articles, and releases from the World Health Organization (WHO). Keep reading for more information about the COVID-19 pandemic and a better understanding of how a highly contagious virus became a global health crisis.
