“鼻”不可挡？近期鼻病毒活跃，专家提醒：虽温和但不能掉以轻心

Core Viewpoint - The recent increase in the positive rate of rhinovirus among outpatient flu-like cases indicates that rhinovirus is becoming a major pathogen for respiratory symptoms, second only to influenza virus in some southern provinces of China [1][3]. Group 1: Rhinovirus Overview - Rhinovirus was discovered in 1956 and is well-adapted to the nasal environment, often being overlooked due to its mild nature [1]. - It is now gaining attention as influenza virus activity declines, with rhinovirus becoming more prevalent among both adults and children [1][3]. Group 2: Symptoms and Impact - Symptoms of rhinovirus infection are generally mild and resemble those of a common cold, including nasal congestion, clear nasal discharge, cough, and throat discomfort, with low-grade fever being rare [3][4]. - In children, rhinovirus accounts for approximately 15% of upper respiratory infections, with its prevalence peaking in May-June and October-November, and it can lead to more severe conditions like asthma exacerbations [4][5]. Group 3: Treatment and Prevention - There are no specific antiviral treatments for rhinovirus; management focuses on symptomatic relief, and antibiotics are only necessary if a secondary bacterial infection occurs [4][5]. - Preventive measures include frequent handwashing and maintaining good ventilation in crowded places, as rhinovirus can survive on surfaces for several days [5].
