Viral Skin Diseases Rubella. Rubella (German measles)  is a viral disease of numerous organs caused by an RNA virus  and accompanied by a mild skin rash called an  exanthem.  First appearing on the body trunk, the  rash spreads to other areas. Pregnant women may transmit the virus across the placenta to the  developing embryo or fetus, and  congenital rubella syndrome  may develop in the newborn.  Damage to the eyes, ears, and heart often result. Immunity can be rendered by an injection of  attenuated rubella virus in the  MMR vaccine.   Measles. Measles  is also called  rubeola.  It is caused by an RNA virus normally transmitted by  respiratory droplets during the coughing stage. Red spots with white centers occur on the cheeks,  gums, and lips and are a diagnostic sign for the disease. These spots are called  Koplik spots.  The  measles skin rash appears as a blush first on the forehead, then on the upper extremities, trunk, and

Chickenpox is a highly contagious disease. Transmitted primarily by respiratory droplets, the disease is accompanied by teardropshaped lesions filled with fluid. The lesions begin on the scalp and trunk and then spread to the face and limbs. Prevention is possible with injections of inactivated VZ virus in the chickenpox vaccine....
