The number of new COVID-19 cases reported outside China on a daily basis has been exceeding the number inside China since February 26. Similarly, starting on March 4, more people have been dying of the disease outside China than inside.

As the COVID-19 spreads across the world, the World Health Organization (WHO) released a report that acknowledged the effectiveness of China's efforts in controlling the epidemic and called on other countries to learn lessons from China.

"I think the key learning from China is speed – it's all about the speed. The faster you can find the cases, isolate the cases and track their close contacts, the more successful you're going to be," said Dr. Bruce Aylward, a public-health expert with the WHO. 

China built Leishenshan Hospital in 10 days to help contain the fast-spreading virus. It is the second specialized hospital for treating COVID-19 patients with mild symptoms.

Apart from the speed, WHO experts say effective quarantines have been a big contributing factor to China's containment of the virus.  

In Wuhan City, the epicenter of COVID-19, local authorities converted stadiums and other public facilities into quarantine centers temporarily. More than a dozen temporary hospitals for patients with mild symptoms of the disease were built within a short time. 

Wuhan temporarily shut down 14 temporary hospitals since March 9. 

According to China's National Health Commission (NHC), over 40,000 medics joined the fight against against COVID-19 in Hubei Province. Most of them went to the frontline to risk their lives to save more patients. 

Chinese manufacturers from various industries were mobilized to plug a shortage of medical supplies. Organizations, businesses and people from all walks of life help ease the shortage of medical supplies, which shows the solidarity and selflessness of the Chinese people. 

Discrimination and disunity won't help humans in the fight against the COVID-19 outbreak. The virus collapses when people united as one and China's experience has proved this.
