What is Roseola Disease – Causes and Symptoms
Roseola is a disease affecting children below the age of two years. Other names of this disease are baby measles, Exanthema subitum and three-day fever. This article tries to understand the causes and symptoms of this disease.
Causes of Roseola Disease: The cause of this disease was not known until recently. Research studies carried out in the United States, Europe and Japan found that this disease is caused by a group of virus known as herpesviruses HHV-6 and HHV-7. 90 percent of infants affected with this disease are infected by a type of HHV-6 virus known as the HHV-6B.
When the condition is present at the time of the birth, it is known as congenital roseola disease. Most babies born with this condition get affected by the HHV-6A type of the virus and inherit it as part of their chromosomes or gene sets.
People suffering from weak immune system should consult the doctor immediately if they feel that they have come in contact with a person suffering from this disease. This highly contagious disease spreads through the saliva of the infected person as well.
Symptoms of Roseola Disease:
- Swollen eyelids
- Mild diarrhea
- Decreased appetite
The fever is among the first symptoms to appear usually in the range of 39–40 degree centigrade. Though in most of the cases the child appears normal, in certain cases fever fits can develop along with the rising temperature of the body. As the child appears to recover from fever after few days, red rashes develop on the trunk, neck and legs which last for one or two days. Liver dysfunction is a rare case however. If the fever lasts for more than 3 days and rashes also do not show signs of improvement within this period, it is time to call the doctor.
