The difference between allergic rhinitis and colds in babies is usually the following: The first aspect that distinguishes the two is the difference in etiology. Allergic rhinitis is due to nasal symptoms that occur under the repeated stimulation of allergens. Cold is due to the symptoms of respiratory virus, or intestinal virus infection. The second aspect is that the clinical symptoms and manifestations are different. Allergic rhinitis is dominated by allergic symptoms, which manifest as nasal congestion, runny nose and sneezing. In addition to symptoms similar to those of severe allergic rhinitis, colds may also have symptoms of fever of varying degrees. In the case of intestinal viral infections, there may also be digestive symptoms such as nausea and vomiting. The third aspect is that the treatment of the two is different. Allergic rhinitis is mainly treated with anti-allergic treatment, and anti-allergic treatment such as loratadine or cetirizine hydrochloride can be taken. In addition to anti-allergic treatment, severe colds also require anti-viral treatment, and can be treated with oral anti-viral Chinese medicines, such as anti-viral oral liquid. In addition, topical application of ribavirin spray, interferon spray, etc. can also be used for antiviral treatment.
