Can rubella be prevented?
Roseola is contagious. Infection spreads when a child with roseola speaks, sneezes or coughs, expelling infected droplets in the air that other people can inspire.
The droplets can also end up depositing on the surrounding surfaces, So, if other people touch these surfaces and then touch their mouths or noses, they can get it.
This disease can be spread during the high fever phase, but it can not be contagious when the rash is declared. There is no way to prevent roseola.
But, since it affects younger children much more than adults, it is believed that an episode of roseola in childhood can give some immunity long-term to this disease. It can be contracted several times, but it is not common.
How is the diagnosis of roseola made?
To make the diagnosis, the doctor will elaborate the patient's medical history and explore it. A diagnosis of this pathology is usually not clear until the fever subsides and the rash appears. At that time, the doctor may send tests to make sure that the fever is not due to another type of infection.
Most treatments focus on lowering high fever. Antibiotics are not good for treating it because this disease is caused by viruses, rather than by bacteria.

Complications of roseola
Some of the complications that can appear are:
Seizures in children
Sometimes, a child with roseola has a seizure triggered by a rapid increase in body temperature. If this happens, the child may lose consciousness and shake his body abruptly. You may also temporarily lose bladder or bowel control.
Seizures related to fever in healthy young children are usually short-lived and, on occasion, harmful. Roseola complications are rare. The vast majority of healthy children and adults with roseola recover quickly and completely.
Weakened immune system
People with weakened immune systems can get a new case of roseola or re-develop a previous infection. Because they have less resistance to viruses in general, they usually develop more serious cases of infection and it is more difficult to fight the disease.
