Young boy displaying the characteristic maculopapular rash of<unk>  Generalized rash on the abdomen due to<unk> <unk>  has symptoms similar to those of flu. However, the primary symptom of<unk>  virus infection is the appearance of a rash (exanthem) on the face which spreads to the trunk and limbs and usually fades after three days, which is why it is often referred to as three-day measles. The facial rash usually clears as it spreads to other parts of the body. Other symptoms include low-grade fever, swollen glands (sub-occipital and posterior cervical lymphadenopathy), joint pains, headache, and conjunctivitis. The swollen glands or lymph nodes can persist for up to a week and the fever rarely rises above 38 °C (100.4 °F). The rash of<unk>  is typically pink or light red. The rash causes itching and often lasts for about three days. The rash disappears after a few days with no staining or peeling of the skin. When the rash clears up, the skin might shed in very small flakes where the rash covered it. Forchheimer spots occur in 20% of cases and is characterized by small, red papules on the area of the soft palate.<unk>  can affect anyone of any age. Adult women are particularly prone to arthritis and joint pains. In children,<unk>  normally causes symptoms which last two days and include: * Rash beginning on the face which spreads to the rest of the body. * Low fever of less than 38.3 °C (101 °F). * Posterior cervical lymphadenopathy. In older children and adults, additional symptoms may be present, including: * Swollen glands * Coryza (cold-like symptoms) * Aching joints (especially in young women) Severe complications of<unk>  include: * Brain inflammation (encephalitis) * Low platelet count * Ear infection Coryza in<unk>  may convert to pneumonia, either direct viral pneumonia or secondary bacterial pneumonia, and bronchitis (either viral bronchitis or secondary bacterial bronchitis). Congenital<unk>  syndrome Child with cataracts in both eyes due to congenital<unk>  syndrome<unk>  can cause congenital<unk>  syndrome in the newborn, this being the most severe sequela of<unk> . The syndrome (CRS) follows intrauterine infection by the<unk>  virus and comprises cardiac, cerebral, ophthalmic and auditory defects. It may also cause prematurity, low birth weight, and neonatal thrombocytopenia, anemia and hepatitis. The risk of major defects in organogenesis is highest for infection in the first trimester. CRS is the main reason a vaccine for<unk>  was developed. Many mothers who contract<unk>  within the critical first trimester have either a miscarriage or a stillborn baby. If the fetus survives the infection, it can be born with severe heart disorders (patent ductus arteriosus being the most common), blindness, deafness, or other life-threatening organ disorders. The skin manifestations are called "blueberry muffin lesions". For these reasons,<unk>  is included on the TORCH complex of perinatal infections. About 100,000 cases of this condition occur each year.
