Acute rhinitis is an acute inflammatory disease of the mucous membrane of the nose caused by viral infection, also known as “cold” or “cold”. Symptoms include nasal congestion, runny nose, fever, etc. The course of the disease usually lasts for 7~10 days. more than 200 types of viruses are associated with acute rhinitis. It can occur in all seasons and is more common in winter. Acute rhinitis is the most common disease in humans and occurs worldwide. Adults usually have an average of 2-5 infections per year, and children may have 6-10 episodes per year (up to an average of 12 episodes per year in school-age children). The annual incidence increases in the elderly due to the deterioration of the immune system. The common causative viruses are rhinovirus, adenovirus, influenza and parainfluenza viruses, and coronavirus. When the body due to a variety of triggers and resistance to decline, the defense function of the nasal mucosa was damaged, such as vasospasm, tissue hypoxia, cilia dysfunction, nasal mucosal damage, SlgA reduction, etc., the virus through the respiratory tract infections invade the organism, or the original latent in the upper respiratory tract of the virus grows and reproduces, virulence and enhancement and cause disease. On the basis of viral infection can also be combined with bacterial and secondary infection. Common causes are: 1, systemic factors: cold, overwork, excessive smoking and alcohol, vitamin deficiency, endocrine disorders and chronic diseases of the body. 2, local factors: nasal septum deviation, inappropriate digging nasal damage nasal mucosa, chronic rhinitis and other chronic diseases of the nasal cavity, 3, neighboring foci of infection: such as chronic purulent sinusitis, chronic tonsillitis, etc., are conducive to the growth and reproduction of pathogens in the local. Induce acute inflammation of the nasal cavity.
