Itchy skin rash with water-clear blisters, possibly fever.

After chickenpox, shingles (herpes zoster) can occur at a later stage. This is not a new disease, as the virus can survive for decades in certain areas of the nervous system. The virus can be reactivated under stress and other factors such as temporary immunodeficiency. This disease is often very painful and occurs much less frequently after chickenpox vaccination.

Since July 2006, the double vaccination against chickenpox has also been available in combination with the vaccination against measles, mumps and rubella(MMRV or MMR + V).

The time between infection with the pathogen and the outbreak of the disease is two weeks (eight to 28 days). Infection is possible two days before to seven days after the appearance of the first blisters, possibly much longer in patients with weakened immune systems.

Siblings or children from the same household require a medical certificate proving immunity through vaccination or a past illness. If this is not possible, they are not allowed to attend the community facility for two weeks. A lockdown vaccination is often still possible up to the third day after the rash appears.

If the course of the disease is uncomplicated, sick children may return to facilities such as school or Kita one week after the onset of the disease. A written medical certificate is not required.
