阳性率上升！除了流感 这种病毒也开始高发

Core Viewpoint - The article highlights the significant increase in respiratory infections among children during the autumn and winter seasons, with a particular focus on the rise of rhinovirus infections, which have become the leading pathogen in respiratory samples tested in hospitals, accounting for 17.5% of cases [1][2]. Group 1: Rhinovirus Overview - Rhinovirus, also known as Human Rhinovirus (HRV), is a small single-stranded RNA virus and a major cause of the common cold, particularly prevalent in children, accounting for 30% to 50% of acute upper respiratory infections [1][3]. - HRV can be transmitted through respiratory droplets and can survive on surfaces for several days, making it easily spreadable, especially among children under three years old [1][3]. - Symptoms of rhinovirus infection typically include nasal congestion, runny nose, sneezing, and sore throat, with most individuals recovering within 7 to 10 days without lasting effects [3][5]. Group 2: Health Risks Associated with Rhinovirus - For vulnerable populations such as infants, the elderly, and those with weakened immune systems, rhinovirus can lead to more severe health issues, including bronchitis and pneumonia [3][4]. - Chronic obstructive pulmonary disease (COPD) patients may experience exacerbated symptoms due to rhinovirus infections [4]. - Complications may include sinusitis and otitis media, with children potentially experiencing more severe symptoms, including gastrointestinal issues like vomiting and diarrhea [5]. Group 3: Prevention and Response Strategies - Preventive measures against rhinovirus include maintaining good hygiene practices, such as frequent handwashing and using tissues or elbows to cover sneezes and coughs [6][7]. - Keeping indoor air well-ventilated and enhancing personal immunity through a balanced diet, regular exercise, and adequate sleep are recommended [7][8]. - In case of infection, individuals are advised to stay hydrated, rest, and use symptomatic treatments without resorting to antibiotics, as they are ineffective against viral infections [9].
