My 4-year-old has a recurring severe cough with rapid breathing and a fast heart rate that improves with Montek syrup, but we received conflicting diagnoses of allergic asthma versus a normal childhood cough; since I catch the same cough from him and we have no family history of asthma, could this actually be allergic asthma (and can it be contagious), and what tests can we do to find the right diagnosis and treatment?
Asthma itself is not contagious, but the viral infections that trigger asthma flare-ups are highly contagious, which explains why you catch her cough. Since her symptoms improve with Montek (montelukast), there may be an allergic or reactive airway component. At four years old, standard lung function tests can be challenging, but a pediatric allergist or pulmonologist can evaluate her through a detailed clinical history, physical exams, and possibly allergy skin prick or blood tests. I highly recommend consulting a specialist to get a clear, reassuring diagnosis and a tailored treatment plan to help your little one breathe easier.
