Infectious causes of vomiting

The commonest infectious cause of vomiting is, rather unsurprisingly, gastroenteritis. However, children tend to have more non-specific syndromes when they get infections. Since they often can't vocalise their symptoms, it is difficult to know exactly what is going on. As such, vomiting can be a sign of any of the following infections:

• Meningitis
• UTI
• Respiratory Infection
• Otitis Media
