Sixth disease (Exanthema subitum)

 The sixth disease, also called Roseola Infantilis or Exanthema Subitum  has an unknown etiology though it is firmly thought that it has a viral origin (human Herpes Virus-6).


It affects children between 6 and 18 months old, but it can also occur in the case of children over that age (pre-school and schoolchildren).


Incubation period:  between 7 and 17 days.


Symptoms:  high fever for 3 or 4 days; when the fever disappears an eruption is seen.  It starts in the trunk and spreads to the arms, legs and face; it lasts 24 to 48 hours.


Despite the fever, the child has a good general condition but it is the pediatrician who decides upon the need to request lab tests if there are doubts about the diagnosis; a child of 2 or 3 years of age, feverish and having no apparent focus of infection is a child who must be under special control and vigilance (we will speak about Hidden Bacteriemia later).


The sixth disease is benign but the diagnosis is generally reached in a retrospective way.


The treatment consists in medical control and antithermics indicated by the pediatrician.


 All feverish little children must have strict medical vigilance.
