Rubella, A Viral Infection

Rubella is a vaccine-preventable disease, so it is more common in young children who have not yet been vaccinated. Find out more about this ailment.

What is it?

Rubella is a highly contagious viral infection characterized by the appearance of a rash (spots or pimples on the skin) and an enlargement of the nodes with usually mild general manifestations.
It typically presents during childhood and is usually benign. In pregnant women it is important, since it can cause malformations in the fetus.


The virus is present in nasopharyngeal secretions in people with clinical and subclinical disease, in blood, urine, feces, and skin.
This disease can be prevented with the MMR vaccine (first dose at 12-15 months and a second dose at 3-6 years of age, or in adolescence when they had not received it before). The vaccine gives protection for life.

Rubella symptoms

The incubation period varies between 10 and 23 days , and the contagion period goes from 1 or 2 days before the appearance of the rash until 6 or 7 days after it. The disease can be practically asymptomatic or present with a low-grade or intermittent fever.
A faint pink rash is observed that begins on the face and chest, spreading to the entire body in approximately 24 hours. It is common to find lymph nodes, frequently in the nape region and in the posterior region of the ears (behind the ear), which are sometimes somewhat painful. A sore throat is common .
Complications, which can be neurological and hematological, are very rare.


There is no specific treatment, only of the symptoms, if any: fever and malaise. It is important that the sick child does not have contact with any pregnant woman .
