Does a mouth blister indicate a stomach infection?

In brief: Sometimes

Some stomach viruses can cause mouth ulcers.
For example, herpangina and hand, foot and mouth illnesses are two common viral infections. They are annoying, but rarely dangerous. There are several other causes of mouth ulcers, including canker sores, minor trauma, or different viruses. In either case, the only treatments required are pain control and fluids.

In brief: Usually Not

Oral ulcers are common in many types of viral infections, but not all viral infections will affect the stomach.
As with most all viral infections they will need to run their course and treating the symptoms is the best way to provide supportive relief to your child as their immune system handles the infection on it's own.
