Doctors report that smokers are more likely to have serious symptoms with Covid-19.
New US research suggests that smokers also catch the disease more easily.
Researchers have discovered that smoking makes the lungs produce a certain protein that makes it easier for the virus to stick to and infect them.
The good news is that high amounts of this protein in smokers’ lungs seem to be temporary. So stopping smoking could possibly lower the amount and reduce the risk of catching Covid-19.
