The parent of a 9-month-old who was diagnosed with respiratory syncytial virus (RSV) yesterday calls the clinic to inquire if it will be all right to take the infant to the first birthday party of a friend's child the following day. Which response should the nurse provide this parent?

Do not expose other children because RSV is very contagious even without direct oral contact.

Make sure there are no children under the age of 6 months around the infected child.

The child can be around other children but should wear a mask at all times.

The child will no longer be contagious, no need to take any further precautions.
