Rubella is a viral disease that belongs to a group of airborne infections.
The highest possibility to get infected with rubella is when the immune system is weakened. A sick person during the incubation period, i.e. the first 5-7 days since the onset is the source of the rubella virus.
The course of the disease in adult patients is heavier compared to children and may lead to serious complications. Therefore, it’s highly recommended to visit a doctor immediately even in case of the slightest suspicion.
