Is asthma an exclusionary condition for SARS-CoV-2 infection in China? -the relationship between asthma and COVID-19
Objective:
To investigate the relationship between asthma and COVID-19.
Methods:
We searched the existing literature and researches to analyze the possible reasons.
Results:
The possible reasons for the very low COVID-19 infection in asthma patients in China may be as follows: the expression of ACE2 in asthma patients is relatively low; the use of ICS in asthma patients may have protective effect; data bias and ethnic differences are also possible reasons, too.
Conclusion:
The relationship between asthma patients and COVID-19 has not been completely clear, which needs further study.
