Six months ago, no one thought Covid-19 existed in the US.

The first reported case came on January 21. Within 99 days, 1 million Americans became infected.

It took just 43 days after that to reach 2 million cases.

And 28 days later, the US reached 3 million cases of the novel coronavirus Wednesday.

The ferocious speed at which Covid-19 spreads has astounded doctors, with over 131,000 people dying from the disease since January, according to data from Johns Hopkins University.

1/21首例，99天後100萬例，又過43天200萬例，再過28天300萬例，也就是說200萬至300萬例那100萬只花了不到一個月時間

8月中400萬，9月500萬，不自由，毋寧死！這句名言也是美國人說的，不愧是全世界最愛好自由的國家
