呼吸道合胞病毒（RSV）是一种常见的呼吸道病毒，尤其在婴幼儿、老年人及免疫力低下人群中易引发严重下呼吸道感染，如支气管炎或肺炎。RSV主要通过飞沫传播，例如咳嗽、打喷嚏，或接触被病毒污染的物体表面后再触摸口鼻眼而感染。目前尚无特效抗病毒药物用于治疗RSV感染，大多数轻症患者可通过对症支持治疗康复，如多休息、补充水分、使用退烧药等。对于高风险人群（如早产儿、有慢性心肺疾病的儿童或老年人），医生可能会考虑使用单克隆抗体药物（如帕利珠单抗）进行预防。预防是应对RSV的关键。日常应勤洗手、避免与患病者密切接触、保持室内通风，并定期清洁常接触的物品表面。2023年起，部分国家已批准RSV疫苗用于60岁以上人群及孕妇（以保护新生儿）。此外，母乳喂养也能增强婴儿对病毒的抵抗力。若孩子出现持续高烧、呼吸急促、嘴唇发紫、拒食或精神萎靡等症状，应及时就医。总体而言，提高公众对RSV的认知、加强预防措施，是减少其传播和重症发生的重要手段。
Respiratory Syncytial Virus (RSV) is a common respiratory virus that can cause severe lower respiratory tract infections—such as bronchiolitis or pneumonia—especially in infants, older adults, and individuals with weakened immune systems. RSV spreads primarily through respiratory droplets from coughs or sneezes, or by touching contaminated surfaces and then touching the eyes, nose, or mouth.There is currently no specific antiviral treatment for RSV infection. Most mild cases resolve with supportive care, including rest, hydration, and fever-reducing medications. For high-risk groups—such as premature infants, children with chronic heart or lung conditions, or elderly individuals—doctors may recommend preventive monoclonal antibody therapy (e.g., palivizumab).Prevention is key to managing RSV. Everyday measures include frequent handwashing, avoiding close contact with sick individuals, ensuring good indoor ventilation, and regularly disinfecting frequently touched surfaces. Since 2023, RSV vaccines have been approved in several countries for adults aged 60+ and pregnant women (to protect newborns). Breastfeeding also helps boost an infant’s immunity against the virus.Seek medical attention promptly if a child shows signs like persistent high fever, rapid breathing, bluish lips, refusal to eat, or lethargy. Overall, raising public awareness and implementing preventive strategies are essential to reducing RSV transmission and severe outcomes.
