Rubella in adults: symptoms, treatment,incubation period

Update: November 2018

Rubella is an infectious disease caused by the same
a virus. The name itself comes from a picture of a red rash –
the main symptom of this disease. It used to be called German
short-term measles or three-day measles
rashes.

Rubella is traditionally a childhood infection. But unvaccinated adults
can also be infected, with rubella
adults are much harder than children.

This infection is especially dangerous for pregnant women.
Intrauterine infection of the fetus occurs in 90% of cases.

There is no specific treatment for this disease. Protect from
infection can only vaccine.

How is rubella infected?

The disease spreads through airborne droplets. That is a virus
can get on the mucous membranes of the mouth and nose when inhaling small particles
saliva or mucus of a sick person.

дней
. That is, during this time the virus multiplies in
body, but so far does not manifest itself.

Particularly high probability of isolation of the virus from the patient:

  • at the end of the incubation period, that is, when the rash is still
    not,
  • during the rash and
  • persists for 5-7 days after the disappearance of the rash.

Infection occurs only with sufficiently close contact,
rubella is less contagious than measles. Usually outbreaks of rubella occur.
in children’s groups. Adults are infected mainly from their
children. Most often among adults, young people under 30 fall ill.
After contact with mucous membranes, the infection is absorbed by
blood and lymphatic vessels.

Statistics

The proportion of adults among all rubella cases is 22%.
Adults sometimes get this infection, despite the fact that
had it in childhood. But mostly sick unvaccinated. Periods
The rise in incidence occurs once every 3-5 years.

Since 2000, after the introduction of compulsory vaccinations, the incidence
began to decline markedly. Currently, the frequency of its detection
less than 1 case per 100 thousand population (for comparison, in 2006 this
the figure was over 500). However, in 2016 there was an outbreak
rubella in the Yaroslavl region (23 cases), with almost all
ill – these were unvaccinated adults aged 25-39
years old.

not, но выделение вируса в окружающую среду уже возможно.

Initial stage (prodromal period). This time of illness
before the rash appears.

  • A few days before the rash increases lymphatic
    knots. Usually it is zaushny, cervical, but may be axillary,
    inguinal. They are felt under the skin in the form of painful mobility.

  • Women may have polyarthritis – swelling and stiffness in
    joints, lasting up to 2 weeks.

Diagnostics

The clinical picture of rubella is very typical and difficult to confuse.
with other infections. Previously, the diagnosis was made only on the basis of
symptoms.

But now, since this disease has become very common
rarely, and the task is to eliminate it completely, any case of it
must be confirmed.

The main methods of laboratory confirmation:

  • virus detection by PCR in the mucous membrane scraping and
    nose;
  • detection of class M antibodies in paired sera by ELISA, or
    the same increase in the titer of antibodies of class G in the second analysis.
