[Intensity of the immunity against measles in employees of the maternity unit in Moscow].

INTRODUCTION: Measles remains an urgent problem in Russian healthcare. Despite the ongoing vaccination, there is an increase in the incidence of measles. Prevention of measles is particularly important in high-risk groups, as well as among healthcare professionals to prevent hospital-acquired outbreaks of infection. The duration of post-vaccination immunity during the elimination of measles has not been sufficiently studied, so often people who  have had measles in childhood or have 1-2 vaccinations against the disease lose their protective antibodies with age in the absence of natural boosterization.Goals and objectives. To study the intensity of specific immunity to measles in employees of the maternity unit. MATERIAL AND METHODS: The study involved 271 employees of the maternity unit aged 21 to 93 years (262 serum samples). The level of IgG antibodies (Ab) to the measles virus in the blood serum was studied by ELISA using a standard set of reagents for the quantitative determination of IgG by «VECTOR-BEST¼. The result was  considered negative if the concentration of IgG to the measles virus in tested sample was ≤ 0.18 IU/ml and  positive - if > 0.18 IU/ml. Results. The number of seronegatives ranged from 0% to 30.8% in female employees with its maximum at age of 31-35 years. The lowest proportion of seronegative and the highest proportion of seropositive women were observed among the elderly, > 60 years. DISCUSSION: There is a marked tendency for an increase of the proportion of persons with average Ab levels with age and a decrease of the proportion of persons with low Ab levels. The percentage of seronegative women among employees exceeded the recommended level, which makes it possible for an nosocomial outbreak when an infection is introduced. CONCLUSION: The authors recommend that serological testing for the intensity of the immune response against measles should be included in the standard of the pre-vaccination screening for adults.

Assessment of the enterobiasis preventive measures in the children's institutions of Leningrad Province demonstrated that wide treatment-and-prophylactic measures didn't reduce enterobiasis. Low efficiency (0.5% of positive results) was found in the sanitary helminthological examination of utensils, which had been performed at the pediatric institutions. The authors found it inexpedient to make planned mass screening of children attending or just entering the preschool institutions. A set of sanitary-and-hygienic and sanitary education measures producing a sustained and reliable effect in enterobiasis control without therapy is proposed to be used.

Workers engaged in automatic moulding mixtures preparation inhale aerosols with the particles' mass-median diameter 3.5 micromicrons, whereas the main parameters of the particle inhaled in steel bar rolling mills are 17.7 and 30.8 micromicrons respectively. The highest content of coarse dust fractions (up to 40 mg/m3) with the particles' diameter above 7 micromicrons, e.i. most affecting the bronchopulmonary system, was found in the cleaners working places. Workers of some other professions inhale dust complex particles with the diameter of 7 micromicrons, and polymodal aerosols with the maximum distribution among the particles within 4.3 and 11.7 micromicrons.
