Why are multiple family members experiencing the same long-lasting symptoms, like cough and post-nasal drip? Is it possible that a single infection is affecting the entire family for several years? What should we do?
When multiple family members have similar long-lasting symptoms, such as cough and post-nasal drip, it is more commonly due to shared environmental factors (such as dust, pollution, mould, dampness, or indoor air quality) or to allergies that affect people living in the same home. Infections usually do not persist for years and spread in this pattern. All affected family members should consult a doctor and also evaluate the home environment to identify and address the underlying cause.
