Asthma May Not Boost Odds Of Severe Covid-19 Today

In the early days of the pandemic, fear was the constant companion for those with respiratory conditions. For individuals with asthma, the logic seemed simple and terrifying: a virus that attacks the lungs would surely be devastating for those whose lungs were already compromised.

Scientists have discovered several biological reasons why asthma might actually offer a strange kind of protection:

The story isn't the same for everyone. While asthma in general may not boost the odds of severe outcomes, remains a concern. A large-scale Swedish study published in February 2026 found that patients with very poor symptom control or frequent flare-ups still faced a higher risk of hospitalization if they contracted the virus.

However, as years of data have poured in, a surprising and reassuring story has emerged. Recent studies, including a major scoping review published in , indicate that asthma is not an independent risk factor for severe COVID-19 illness. The Protective Paradox In the early days of the pandemic, fear

: 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.

For most, the message is clear: staying consistent with daily medications and keeping asthma well-controlled provides a robust layer of protection, allowing many to "breathe easier" despite the ongoing presence of the virus. While asthma in general may not boost the

: 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.
