: People with asthma often have higher counts of eosinophils , a type of white blood cell. Research suggests these cells may help degrade viral RNA and boost the immune defense specifically against this virus. AI responses may include mistakes

: The SARS-CoV-2 virus enters cells via a receptor called ACE2 . In many people with allergic asthma, the expression of this receptor is naturally lower, giving the virus fewer "doors" to enter through.
