Rotavirus is a highly contagious virus that causes diarrhea, which is a common illness in children and adults worldwide. Before the development of a vaccine, most children had been infected with the virus at least once by age 5. Although rotavirus infections are unpleasant, they can usually be treated at home with extra fluids to prevent dehydration. In severe cases, hospitalization may be necessary to receive fluids through a vein.
Rubella, also known as German measles or three-day measles, is a contagious viral infection that is characterized by a distinctive red rash. While it is often referred to as a "mild" illness, rubella can cause serious problems for unborn babies whose mothers become infected during pregnancy.
Rumination syndrome is a condition in which someone repeatedly regurgitates undigested or partially digested food from the stomach. This process occurs without any effort or intention, and the regurgitated food is then chewed again and swallowed or spit out. Rumination syndrome is often misunderstood as a form of self-induced vomiting, but it is a distinct condition that requires attention and treatment.
A ruptured eardrum, also known as a tympanic membrane perforation, is a hole or tear in the thin tissue that separates the ear canal from the middle ear (eardrum). This condition can cause hearing loss, middle ear infections, and other complications. In most cases, a ruptured eardrum heals on its own within a few weeks, but in some cases, it may require treatment to heal.
A ruptured spleen is a medical emergency that occurs when the surface of the spleen breaks, causing internal bleeding and potentially life-threatening complications. The spleen, located just under the rib cage on the left side of the body, plays a vital role in the body's defense against infection and filtering out old blood cells from the bloodstream.
