[Laboratory diagnostics of HIV infection in Syberian federal district].

Spread of HIV infection in the Russian Federation is an important problem of the state healthcare. Data on HIV infection diagnostics in the Syberian federal district in 2005-2009 are presented. Coverage of population by HIV examination, rate of positive study results by enzyme immunoassay and rate of positive EIA confirmed by immunoblotting are presented.

[Strategic problems in counteracting the spread of HIV infection in the Altai Territory]. / Nekotorye voprosy strategii protivodeistviia rasprostraneniiu VICh-infektsii v Altaiskom krae.

The Altai Territory belongs at present to regions with the insignificant level of the spread of HIV infection. By December 1, 1999, the Altai Territory had 31 registered cases of HIV infection, which constituted 1.33 per 10,000 of the population (the corresponding figure for the whole of Russia being 14.92). But the situation with HIV/AIDS showed the general tendency to the development of the epidemic of HIV infection due to steady growth and the wide involvement of injecting drug users in the epidemic process. Before 1999 all cases of HIV infection registered in the Altai Territory were imported. Out of 31 HIV infected persons detected in the territory, 18 were injecting drug users. In 1999 local foci of HIV infection were formed among drug users in two big cities of the Altai Territory, which was indicative of the gradual transition of HIV infection from the phase of the registration of individual cases to the phase of the formation of local foci among some groups of the population.

[The principles of pre-epidemic diagnosis in the epidemiological surveillance system for HIV infection]. / Printsipy predépidemiologicheskoi diagnostiki v sisteme épidemiologicheskogo nadzora na VICh-infektsiei.

The problem of the general introduction of the principles of the pre-epidemic diagnostics of HIV infection was discussed. These principles should be based on the observation of "model" infections (viral hepatitides B, C, D), multipurpose serological monitoring and sociological methods aimed at obtaining the necessary information. The suggestion that the age and sexual structure of HIV-infected patients would be determined by the route of HIV transmission, prevailing on a given territory, including into infection process adolescents and young women and men was made.

[Problems in and the means for improving the epidemiological surveillance of HIV infection]. / Problemy i puti sovershenstvovaniia épidemiologicheskogo nadzora za VICh-infektsiei.

The system of the epidemiological surveillance of HIV infection, existing now in Russia and aimed at the detection of sources of the infective agent, is not adapted for territories with a low level of HIV infection among the population. This makes it impossible to evaluate the factors which may contribute to the epidemic spread of the infective agent. A new program of epidemiological surveillance is proposed. This program is based on the complex approach to monitoring infections having epidemiological signs, common with HIV infection; on the organization of serological monitoring for the detection of HIV-seropositive persons on the basis of blind tests and orientation on monitoring the social factors which determine the spread of HIV infection.
