2Acute infectious rhinitis, also known as the common cold, nasopharyngitis, rhinopharyngitis, or acute coryza, is caused by one of more than 200 viral types and most commonly involves rhinovirus (Arcangelo et al., 2017). The common cold is a viral upper respiratory infection. It is widely spread in all countries and more common in crowded areas and small children. Most cases of the common cold usually occur during the winter months. Common cold symptoms are usually fever, sore throat, frequent sneezing, nasal congestion, watery eyes, and coryza. Coryza is an acute inflammation of the mucous membranes of the respiratory passages, particularly of the nose, sinuses, and throat, and is characterized by sneezing, rhinorrhea or watery nasal discharge, and coughing (Arcangelo et al., 2017). The common cold is the third most common primary diagnosis in office visits (Fashner et al., 2012). The virus is spread anywhere through the direct or indirect contact with secretions of the infectedpeople. The incubation period can vary and lasts nearly two days. Afterward, the peak of the symptoms lasts for 1–3 days, and the infected feel relief after 7–10 days (Allan & Arroll, 2014). The symptoms and the period associated with the common cold can vary depending on many factors including the age, the lifestyle, and the immune system functioning.
