Rubella: Symptoms and Rash in Children and Adults

Rubella (German measles, "third disease") is a viral infection that usually resolves in about a week. It is dangerous mainly for pregnant women: if infected early in pregnancy, the virus can harm the fetus. Half of those infected have no symptoms at all, but such people can still transmit the virus.

What rubella is and who gets it

The causative agent is Rubella virus; humans are the only known host. The virus is transmitted by airborne droplets through coughing and sneezing. The incubation period is about 15–24 days, on average 17. A person becomes contagious approximately 7 days before the rash appears and remains a source of infection for up to 7 days after the rash.

Thanks to mass vaccination, the incidence worldwide has dropped sharply: from 670,894 cases in 2000 to 17,865 in 2022. In the WHO European Region, 494 cases were registered in 15 countries between September 2023 and August 2024, of which 15 were in Ukraine. If you have received both doses of the MMR or MMRV vaccine or have already had rubella, the likelihood of rubella is very low.

First signs of rubella

About half of people with rubella have no symptoms. Others may have a mild fever, enlarged lymph nodes in the neck and behind the ears, headache, sore throat, cough, runny nose and sneezing, and red eyes. Adults often have pain in the fingers, wrists, or knees. The rash appears 2–3 weeks after infection and lasts several days.

Rubella rash: what it looks like and how it spreads

The main sign is a spotty rash that starts on the face or behind the ears and spreads to the neck and body. On light skin it looks red or pink; on dark skin it is harder to notice, but it may feel rough or bumpy. Some people have no rash at all.

• The rash starts on the face or behind the ears and moves to the neck and body
• Appears 2–3 weeks after infection
• Usually lasts several days
• Accompanied by enlarged lymph nodes in the neck and behind the ears

Rubella in children: course features

In children the illness is usually mild and resolves in about a week. Besides the rash, there may be fever, cough, runny nose, sneezing, and enlarged lymph nodes. The rash usually lasts several days.

Rubella in adults: symptoms and features

Adults more often have joint pain — in the fingers, wrists, knees; this is especially characteristic of young women. Headache, sore throat, fever, and red eyes are possible. The course generally remains mild.

How rubella differs from measles and when to see a doctor

Rubella is called "German measles," but these are separate infections. The MMR or MMRV vaccine protects against both measles and rubella. If you suspect rubella in yourself or your child, see a doctor; it is better to call ahead to discuss the appointment by phone. The doctor assesses the rash, lymph nodes, and general condition, and orders tests if necessary. There is no specific treatment; the MMR or MMRV vaccine prevents the disease.

Rubella itself is not a reason to call an ambulance. A pregnant woman with a new rash or contact with someone who has rubella should contact a doctor urgently; 103/112 — for a life-threatening condition when help is needed immediately.
