The intensity, duration and recurrence of the symptoms vary from person to person. Even in the same person the symptoms may vary from episode to episode . Some people with asthma may have extended symptom-free periods, interrupted by periodic asthma episodes, while others may have some symptoms every day. Very often some people with asthma have symptoms only during exercise, or when they are exposed to allergens or viral respiratory tract infections. |
