This is caused by a virus, which is usually spread by droplets during coughing, sneezing or drinking from the same vessel as an infected person. It is predominantly a childhood disease, but can be quite severe if caught by an adult. It takes around 7-10 days to develop and the child is usually infectious until the last scab disappears.
It usually starts with mild fever, a general feeling of malaise, which gradually leads to the development of red rashes appearing on the face, back and scalp, and genitalia. The child becomes irritable and itchy with the rashes developing into water-filled areas with surface scabs.
The following are recommended treatments:
Cool baths every 4-5 hours without soap but with a few spoonfuls of Sodium Bicarbonate. This soothes the skin and reduces itchiness.
For the fever, Paracetamol or Ibuprofen (provided the child is not asthmatic) will help control temperature.
Calamine Lotion is a good soothing agent.
Anti-histamine like Piriton helps stop the scratching and thereby reduces chances of secondary infections.
Give plenty of fluids and light food.
Do not scratch the scabs to avoid getting scars.
