The natural reservoir is the man.

The sources of sickness are represented by:

• Patients with an asymptomatic form of disease (about 50% of total infected persons), or
• Patients with symptomatic disease;
• Newborns with congenital rubella.

Method of transmission

The mode of transmission is direct, aerogenic. The patients eliminate the virus through saliva drops. Another route of transmission is the transplacental pathway (congenital rubella).

Rubella is less contagious than measles or influenza. Close contact is required for the virus to be transmitted.

Risk groups

Children and medical staff, education staff and nursery / children’s homes.
