Hand, foot, and mouth disease is one of many infections that causes mouth sores. Health care providers can usually identify mouth sores caused by hand, foot, and mouth disease by considering
- How old the patient is
- What symptoms the patient has
- How the rash and mouth sores look
A health care professional may sometimes collect samples from the patient’s throat or feces (poop), then send them to a laboratory to test for the virus.
