The novel coronavirus disease (COVID-19) epidemic is a major public health emergency that has spread the fastest, caused the most extensive infections and been the hardest to contain since the founding of the People's Republic of China in 1949.

Under the strong leadership of the Communist Party of China (CPC) Central Committee with Comrade Xi Jinping as the core, China has taken the most comprehensive, the strictest and the most thorough prevention and control measures to battle the epidemic. In their tenacious fight against the coronavirus, 1.4 billion Chinese people have pulled together in tough times and paid a tremendous price and sacrificed a lot.

With the joint efforts of the whole nation, the positive trend in preventing and controlling the epidemic in China has been constantly consolidated and expanded, and the restoration of normal production and everyday life has been quickened.

The pandemic has recently been spreading rapidly across the world, posing a formidable challenge to global public health security. According to data from the World Health Organization (WHO), COVID-19 had affected more than 200 countries and regions with over 1.13 million confirmed cases by April 5, 2020.

Virus knows no national borders, and the epidemic distinguishes no races.
