Perhaps it is impossible to find a single person who has not undergone a Mantoux test at least once in his entire life . As a rule, in all schools this
The procedure is mandatory. Mantoux is a vaccine, the sizes of which show how much the human body contains immune cells that determine the presence of tubercle bacillus. And from how many there are, the vaccination reaction will be greater.
Vaccination Features
Usually, after a subcutaneous injection was made with a special vaccine, on the second and less often on the third day, a specific seal appears in that place. This redness is round in shape and a reddish tint, to a small extent, allocated on the surface of the skin. Mantoux is a vaccine, the sizes of which are analyzed after seventy-two hours, and this is considered the most reliable information. Therefore, she is examined by a specialist during this period.
What do vaccine sizes mean
The reaction to the Mantoux test is a result that shows whether a person is healthy or whether he needs an additional, more complete examination. The diameter of the seal - this is the size of the Mantoux vaccine , the norm is determined by its borders, while the resulting redness around the so-called “buttons” is not taken into account. If the papule is absent, then pigmentation can be recorded as a result. Mantoux reaction should be measured using a transparent ruler. The following results are distinguished:
- Negative reaction. It is determined when the seal has a size of 0-1 mm. This is usually an injection mark.
- The reaction is doubtful in the case of seal sizes from 2 to 4 mm, and if it is together, like redness, is absent.
- With a positive reaction, the boundaries of the seal are clearly defined, and the dimensions reach a diameter of 5 mm or more. Mantoux vaccination sizes in children are as follows: with a weakly positive reaction - from 5 to 9 mm, medium intensive - from 10 to 14 mm, severe - from 15 to 16 mm.
- With a pronounced reaction, the seal size is from 17 mm.
When the result was positive
When Mantoux (vaccination) is given, the sizes to which it should correspond with a negative result are known, it remains to wait for the conclusion of a specialist. A person always hopes for the best and in this case is quite sure that his child is completely healthy. What to do when the answer is positive?
Do not panic and prepare for the worst. After all, even if there was a positive reaction, then this does not confirm the presence of a disease such as tuberculosis. In the child's body, this stick is present, but the child is not infectious, since the bacterium is not transmitted by blood.
The disease is spread by airborne droplets in people who have tuberculosis disease.
This means that the child is infected, but is not sick and is not able to infect others, because his immunity is able to suppress microbacteria. If the child was given a Mantoux (vaccination), the sizes of which during the test showed a positive result, then they will have to be registered with the TB doctor and under his supervision. However, they are not prohibited from attending school and preschool institutions.
