Infantile asthma is a specific, allergy-related, noninfectious disease. Most asthma attacks in infants and children are associated with viral respiratory infections. That is, viral respiratory infections can trigger asthma attacks. Asthma itself is not contagious, but the viral respiratory infections that trigger asthma can infect babies who are in close contact with the sick child. In the case of syncytial viral infections, the infected baby may also develop wheezing symptoms. Therefore, it is important to avoid close contact between the baby and the sick child. Babies with infantile asthma should eat a balanced diet, take vitamin D supplements, and add complementary foods on time, but do not eat foreign proteins, such as seafood and other meats that are allergy-prone, too early. Before half a year old, avoid adding protein-based complementary foods, exercise and get more sunshine, keep the room well ventilated, and avoid contact with allergy-prone pet plush toys. Don’t eat foods that are too sweet, and don’t use any scented or otherwise odorous items or things in the room, like disinfectant, to avoid constant respiratory irritation.
