감기 비슷한데 폐렴, 사망까지…RSV 백신, 가을 유행 전에 맞아야 [건강한겨레]

RSV, or respiratory syncytial virus, is an airborne infection that can cause serious complications for vulnerable groups such as the elderly and immunocompromised. Though its symptoms resemble the common cold, for the elderly and those with pre-existing conditions, it can lead to pneumonia, hospitalization, and even death. Health authorities recommend RSV vaccination beginning in August before the onset of the annual respiratory illness season.

The number of hospitalized older individuals with RSV has more than doubled compared to the same period last year. Due to aging-related changes in lung function and weakened immune response, older individuals are at a higher risk of developing pneumonia and experiencing severe complications from RSV infection. Studies show that among hospitalized older adults with RSV, 56.8% were diagnosed with pneumonia, and the risk of severe complications is significantly higher compared to bacterial pneumonia.

The duration of recovery from RSV infection also leads to prolonged health issues for the elderly, such as repeat hospitalization and reduced independence. Even for those without pre-existing conditions, RSV can have serious consequences, especially for individuals with chronic respiratory diseases like asthma or COPD, heart disease, diabetes, and those who have undergone organ transplantation.

RSV vaccination is the most effective preventive measure, especially since the virus tends to spread earlier than influenza.
