For RSV in children, what is the primary care approach?

For RSV (Respiratory Syncytial Virus) in children, the primary care approach is primarily supportive care. RSV is a viral infection that affects the respiratory tract, causing symptoms such as cough, congestion, and difficulty breathing. Antibiotics are not effective against viruses like RSV, so they are not the appropriate treatment. Surgery is not indicated for RSV in children as it is a viral infection that typically resolves on its own with supportive care. Therefore, the correct answer is B.
