VIRAL-INDUCED ASTHMA

Many factors can trigger asthma, including exercise, cold air, mold, allergens, and airborne irritants. However, viral infections are actually the most common asthma trigger. As many as 95 percent of children and 80 percent of adults with asthma have flare-ups caused by viral infections. These viruses include the ones we face every day: colds, the flu, RSV, and COVID-19. Many researchers suspect that viral-induced asthma (or viral asthma) is so common because chronic asthma damages the airways and makes them more susceptible to infection. Symptoms are similar to a regular asthma attack, but also include cold or flu-like symptoms. Viral asthma often lasts longer than typical asthma attacks, as the body must fight the infection to recover.

P.S. Scientists are still unsure whether viral infections cause asthma or simply make it worse.
