Wuhan for instance has has a >50% smoking rate and high air pollution. They also have poor trap systems in multitenent housing for not spreading sewage germs, which can be aerosolized by toilets flushing. Hygiene practices in China are also well below the western world.
SARS-CoV-2 virus attaches it to ACE2 receptors found in lungs and intestines. Smokers, those who live in high pollution areas have more ACE2 receptors in their lungs. So the conditions seen in China are different than elsewhere.
It just hasn't spread enough globally to see if the numbers are the same outside of China as they are inside.
