Hand, foot and mouth disease is a highly contagious viral infection that mostly affects children under the age of 10. Whilst the condition can be unpleasant for your child and make them feel uncomfortable, in most cases it poses no serious threat to their health. There have been some instance of life threatening brain infections (encephalitis) associated with hand, foot and mouth disease infections caused by one particular viral strain, but these only seem to have occurred in the Asia-Pacific region of the world.
Hand, foot and mouth disease in adults is rare, but again the symptoms can cause severe discomfort. Due to it being so contagious, it is advised that people and the workplace are avoided until the disease has completely cleared up.
