List of Highly Contagious Diseases
-
Varicella (Chickenpox)
-
Varicella, more commonly referred to as chickenpox, is a highly contagious disease that most commonly affects children. Most people only catch varicella once, but the disease can lie dormant in your body and later cause an outbreak of a similar disease, shingles. Varicella is characterized by a blotchy rash that spreads over the entire body, including the genitals, ears, nose and mouth. Varicella is highly contagious because it spreads through coughing and sneezing, even before symptoms appear. A vaccine is available for children who are least 12 months old.
Measles (Rubeola)
-
Measles, or rubeola, is an airborne respiratory disease that infects 20 million people worldwide each year. Measles is spread through small droplets when an infected person sneezes or coughs without covering his mouth. The most prominent characteristic of this disease is the full-body rash that accompanies it, but other symptoms include runny nose, cough, red eyes and a fever. There is a measles vaccine available that is usually administered to children who are 12 months of age or older.
