It is not easy to determine whether an illness is RSV and not the flu, cold, or COVID-19. But some differences do exist that might help you identify what your child has. For starters, the flu comes on quickly as a severe respiratory infection, causing your child to feel very sick. In contrast, RSV and a cold can come on gradually, maybe as a tickle or a scratch in the throat, or as a little runny nose. The only assured way to diagnose RSV is to get a test, but doctors don't routinely test for these illnesses, so we advise that you simply make sure your child is hydrating and that you continue to provide loving care. Remember, too, that most people do fine with RSV but do monitor whether your child is becoming sicker. If so, you may need to consult your doctor.

COVID-19, however, is different to RSV, the flu, or a cold. It can appear in different forms. Some people start with vomiting or diarrhea. Other people start with respiratory symptoms. When in doubt, ask for a COVID-19 test. That way you can care for your child as your doctor recommends while also better protecting other family members from catching COVID-19.
