Thanks for your question on Health Care Magic. I can understand your situation and problem. Asthma patients are at increased risk of respiratory infections due to poor lung defense. And most common infection is viral infection. Amongst viruses, Influenza virus is more common. So for your symptoms, recurrent viral infections (mostly Influenza) is likely cause. And fir this, annual vaccination with Influenza vaccine is advisable. This will provide sufficient immunity to prevent recurrent Influenza infection. Also take your asthma drugs timely because control of asthma is also important in prevention of symptoms. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
