The study aims to see if obeldesivir (ODV), a medicine, is safe and helpful for kids with Respiratory Syncytial Virus (RSV). RSV is a virus that can cause lung infections. The study will check if ODV helps kids feel better faster.

Key Points:

• Kids up to 5 years old with RSV can join. They must not have other serious infections or conditions like asthma.
• The study is for infants and children, divided into two groups based on age and weight.
• Kids must have RSV symptoms and a negative test for other viruses like flu and COVID-19.

Participants cannot join if they've needed hospital care for RSV recently, have other lung issues like cystic fibrosis, or have taken certain medicines. The study will help understand if ODV can safely reduce RSV symptoms in children. Parents should consider their child's health history and current condition before enrolling.
