Viral mucositis
Normal human skin contains bacteria and fungi. Candidiasis occurs when the fungus overgrows and invades the skin. Risk factors include warm moist environments and a weakened immune system.
Inflammation of the mouth surface causes ulcers. Various factors can cause this, such as vitamin deficiencies, medications, and autoimmunity (the body's immune system attacking itself). Often, no clear cause is found, and the ulcers heal on their own.
Uveitis
Epilepsy is a neurological disorder where brain activity becomes abnormal, causing seizures of varying durations and severities. It can affect people of any age and may be caused by genetic disorders or brain injuries, such as stroke.
