First of all, colds are highly contagious, so most of them occur in groups, such as families, schools and work environments; allergic rhinitis is not contagious, but is genetically related, so families with blood relatives who have a history of allergic diseases, including allergic rhinitis, asthma, skin allergies, drug allergies and other allergies, are more likely to have attacks.
Secondly, nasal symptoms such as sneezing, runny nose and nasal congestion of cold are often continuous and will last for several days, with the control of cold, the symptoms gradually reduce and finally relieve; while allergic rhinitis attacks are paroxysmal and may occur only once or several times a day, more obvious in the early morning or after the stimulation of odor, etc. After the attack as normal, allergic rhinitis is usually not accompanied by fever, while cold is often accompanied by fever.
Allergic rhinitis is characterized by frequent sneezing and clear water-like nasal discharge, while cold is characterized by less sneezing, less nasal itching, obvious and persistent nasal congestion, and nasal discharge that can change from clear or mucous to purulent; cold is characterized by heavy systemic symptoms, such as chills, fever, weakness of limbs, myalgia, headache, sore throat, gastrointestinal discomfort, while allergic rhinitis is characterized by nasal symptoms only or accompanied by asthma or skin allergy.
Finally, the duration of the disease is short, usually 1-2 weeks, while allergic rhinitis has a longer duration and recurs throughout the year.
It is important to pay proper attention to allergic rhinitis, especially when your child’s “cold” symptoms are not cured, you must take your child to a specialist hospital for diagnosis and treatment in time to avoid further complications caused by allergic rhinitis.
If you don’t understand allergic rhinitis, you always think that allergic rhinitis is a minor disease that doesn’t require treatment, and that children, for example, grow up and get better. This is a completely wrong viewpoint, clinical medical research results have confirmed that 60-80% of patients with allergic rhinitis can develop allergic asthma. Since the upper and lower respiratory tracts are anatomically continuous, the inflammation of the upper respiratory tract in allergic rhinitis can easily spread downward and develop into asthma, which is medically known as allergic rhinitis-asthma syndrome, called “the same airway, the same lesion”.
