The Korea Centers for Disease Control and Prevention (Director Ji Young-mi) announced that respiratory syncytial virus (RSV) infections increased 2.2 times in one month compared to early February, prompting postpartum care centers, neonatal rooms, and infant care facilities to use respiratory systems to prevent mass outbreaks. They were requested to strengthen the prevention and control of infectious diseases.
In the 9th week of 2023 (February 26 – March 4), a total of 214 patients were reported for respiratory syncytial virus infection.

It has been confirmed that the incidence is increasing, especially in infants and young children. The percentage of patients aged 0-6 years who reported respiratory syncytial virus infection at 9 weeks: 72.9%

Mild case symptoms can include congested or runny nose, dry cough, low-grade fever, sore throat, sneezing, and headache.
