With the aggravation of air pollution, the incidence of rhinitis and cough caused by allergy is higher and higher in children, and the symptoms are very similar to colds. How should parents distinguish them? We can identify from the following years:

① many allergic respiratory diseases have seasonal manifestations. Spring and autumn are high incidence periods. The cause is caused by children’s exposure to some allergens. Common allergens include fungi, pollen, cockroach allergens, organic compounds, dust mites, molds, formaldehyde, pet dander and second-hand smoke. If parents observe carefully, The onset of allergic diseases in children can always be followed. The onset of cold is not seasonal, but it is generally caused by virus and bacterial infection;

② allergic respiratory tract infection will occur repeatedly if the allergen is not removed. It can heal itself for several days each time, generally without fever. Colds are often acute, usually lasting 7-10 days. In addition to respiratory symptoms, there will also be systemic symptoms such as fever, muscle soreness and joint pain;

③ patients with allergic respiratory diseases will have severe sneezing, dry cough and other symptoms. Sneezing can be repeated for several to dozens at a time. Cold patients will also sneeze, but they will not sneeze for dozens of times in a row. The main symptoms are nasal congestion, fever and so on. Runny nose usually appears in the early stage of a cold, and the amount is not much. Allergic rhinitis is accompanied by sneezing and a large amount of runny nose;

④ in terms of treatment, the effect of ordinary anti-inflammatory or anti-virus treatment for allergic respiratory diseases is not good, while the cold is just the opposite. However, due to the certain self limitation of allergic diseases, they will quickly return to normal after being separated from allergens, so it is easy for parents to have the illusion of effective treatment.
