Rubella

Rubella may be discreet, but infection during pregnancy may have serious consequences for the foetus.

Documentary Enrichment: · General information

Essentials

Infection often benign but likely to cause serious malformations when it occurs during pregnancy.

Agent
Rubella virus
Transmission or exposure
Respiratory tract · Materno-infant transmission

Situation and vulnerability

The onset of pregnancy is particularly sensitive. A mild rash in adults does not reflect the fetal risk.

Signs and limits of their interpretation

Eruption, moderate fever and lymph nodes are possible. Some infections go without symptoms.

Diagnosis and monitoring

Confirmation requires appropriate examinations. Serological results during pregnancy should be interpreted with previous dates and results.

Prevention and care

Prevention is based on vaccination according to schedule. Check protection before pregnancy and discuss contact quickly during pregnancy.

Practical issues

Are rubella and measles the same disease?

No. They are due to different viruses and have distinct consequences and approaches despite some resemblances of eruption.

Preparing for an exchange with a professional

  • Pregnancy term and date of contact
  • Vaccine diary and previous analyses
  • Start of eruption and displacement

Bring the full minutes and dates. This information facilitates evaluation; its collection must not delay an urgent appeal.

Individual decisionThe choice of a test, treatment or prevention depends on the local situation and recommendations. In case of distress, call 911.
