Is this Rubella?
Rubella, also known as German measles, is a viral infection that affects the respiratory system. Although once a very common childhood condition, due to the development and prevalence of the Rubella vaccine, it is now extremely rare in developed countries where vaccination against this disease has become the norm.
Symptoms include a measles like rash, and a mild fever. In most cases, the infection is very self-limiting, and cease within a few days, and is sometimes called the three day measles. Complications are extremely rare for babies with Rubella. The symptoms are generally worse when Rubella is contracted as an adult. Also, if a mother contracts Rubella during her first trimester, this can cause miscarriages or severe impairment in the newborn if the baby survives to birth. This is the main reason that vaccinations are conducted.
Consult your pediatrician for proper vaccination of your baby, and if your baby is suffering from a skin problem, and the condition appears to persist, visit a pediatrician for advise.
