In what year did SARS occur?

SARS first appeared in Foshan City, China in 20021early October. Because of the symptoms of pneumonia, the patient was classified as atypical pneumonia at that time, and the China media generally called it "SARS". Since then, the disease has spread rapidly to Hong Kong through tourism, commerce and immigration, and from Hong Kong to Vietnam, Singapore, Taiwan Province Province and Toronto.

In May 2003, the epidemic situation in Beijing and Hong Kong was the most serious. In the summer of 2003, the number of infected people decreased for a few days, and the disease was completely controlled. In June 2003+June 2003+10, sporadic cases appeared again in Guangzhou, and in March 2004, suspected SARS cases appeared again in Beijing, but none of them turned into epidemic again.

After March 2003, the epidemic spread to the whole country, especially to Beijing. On June 24th, 2004, the World Health Organization (WHO) announced the lifting of the travel ban in Beijing, which marked Chinese mainland's victory over SARS.
