VSIV can infect insects, cattle, horses and pigs. It has particular importance to farmers in certain regions of the world where it infects cattle. This is because its clinical presentation is identical to the very important foot and mouth disease virus. The virus is zoonotic and leads to a flu-like illness in infected humans. It is also a common laboratory virus used to study the properties of viruses in the

However, other studies report no correlation between aphthous stomatitis and menstrual period, pregnancy or menopause. Aphthous stomatitis is uncommon in people who smoke, and there is also a correlation between habit duration and severity of the condition. Tobacco use is associated with an increase in keratinization of the oral mucosa. In extreme forms, this may manifest as leukoplakia or stomatitis nicotina (smoker's keratosis).
