What led to health concerns in China?
Urbanization gave rise to modern cities and job opportunities. People started migrating from rural areas to cities. Overcrowded cities led to major health concerns, such as the SARS.
When so many people live in overcrowded places in large cities, they are more prone to get diseases such as flu, influenza, and other viral diseases such as SARS. In overcrowded places due to urbanization, diseases spread more easily, and that was the concern of the Chinese government. Even today, with the pandemic that the world is living in, the disease spread in larger cities due to the fact that there are too many people living in small places.
