Doctor warns of RSV risk to seniors, heart patients

Doctor warns of RSV risk to seniors, heart patients

2026-10-27

With flu season in full swing, another easily overlooked virus merits equal caution: respiratory syncytial virus, or RSV. Its symptoms closely resemble the flu, but it has no targeted antivirals, and rapid tests often show false negatives in adults. A doctor warned that elderly people and those with chronic diseases are at especially high risk.

Coughing, runny nose, and fever are familiar flu symptoms. They’re also common symptoms of respiratory syncytial virus, or RSV, making it easy to miss during flu season. But its threat shouldn’t be understated, as it can trigger pneumonia or exacerbate heart failure.

Not long ago, I saw a patient in their 60s or 70s who previously had a stent implanted for a heart attack. After contracting RSV, their body’s delicate balance was disrupted, and their condition deteriorated rapidly. By the time they went to the ER, their blood oxygen levels had dropped and they were in respiratory failure, requiring immediate intubation in the ICU.

Dr. Lee said RSV can trigger pneumonia and respiratory distress in elderly and chronically ill patients, while severe infection can elevate the risk of cardiac events such as atherosclerosis or heart attack, with impacts extending far beyond the respiratory system.

People with pre-existing conditions are more susceptible to RSV infection, and catching RSV can trigger other underlying conditions, creating a vicious cycle. Since there are no specific antivirals to treat RSV, it wasn’t routinely tested for.

RSV screening often turns back false negatives in adults, leading many to overlook its risks. Susceptible groups such as the elderly, those with chronic cardiovascular or pulmonary diseases, and people with diabetes should exercise extra caution. Doctors advise that the simplest methods remain the most effective: Wash your hands, wear a face mask, avoid contact with sick people, and get vaccinated. Extra care should be taken when spending extended periods indoors or in crowded places. Since there’s no cure for RSV, prevention remains far better than treatment.

"RSV"呼吸道融合病毒像流感 醫生:長者.慢性病患高風險群

2026-10-27

正值流感季節,還有另一種病毒也得特別留意,因為它很容易被大家忽略,RSV呼吸道融合病毒,症狀跟流感很像,可是沒有特效藥,在成人中篩檢的偽陰性很高,醫師提醒,尤其是年長者、慢性病患者都是高風險族群。

咳嗽、流鼻涕、發燒,RSV呼吸道融合病毒,症狀跟流感很像,特別容易在流感季節被忽略,但它的威脅可不容輕忽,很可能引發肺炎或讓心衰竭惡化。

“我前陣子就有遇到一個60、70歲的患者,之前心肌梗塞放過支架,(後來)呼吸道融合病毒RSV感染之後,打破原本的平衡,過幾天(病程)進展很快,等到很不舒服去急診,結果馬上就發現,血氧掉了,呼吸衰竭,馬上緊急插管加護病房”

醫師說,RSV對長者、以及慢性病患者來說,除了可能引發肺炎、呼吸窘迫,嚴重還會提高動脈粥狀硬化、及心肌梗塞等心血管疾病發生機率,影響遠超過呼吸道本身。

[[淡水馬偕醫院心臟內科醫師 李俊偉]]
“你有這些慢性病的人,比較容易感染呼吸道融合病毒,你感染呼吸道融合病毒,也容易誘發(其他疾病),有點是一種雙向的惡性循環,因為它沒有特別針對,呼吸道融合病毒治療的藥,因此過去不常檢驗”

成人中,偽陰性的比例很高,大家很常因此忽略,高風險族群像是年長者、慢性心血管疾病患者、慢性肺病患者、以及糖尿病患者都得特別注意。醫師建議,最簡單的最重要,勤洗手、戴口罩、避免接觸生病者、以及疫苗接種,如果長時間待在室內、人多地方要特別注意,否則,呼吸道融合病毒感染後沒有特效藥,預防勝於治療,才能讓自己保持健康。
