Epidemiological Aspects of Arbovirus Infections in the South-Eastern Part of Azerbaijan

Sultanova Ye. A.

The purpose of the work was to study the epidemiological aspects of arbovirus infections in the southeastern part of Azerbaijan using serological studies and questionnaires using forms developed by us. Materials and methods. The study involved 633 residents of the southeastern part of Azerbaijan (Lankaran, Masally districts, the territory of the Qizil-Aghaj State Reserve), who underwent a serological survey on a voluntary basis. Results and discussion. Seropositive were 15.3 ± 1.4% of the examined. 6 types of arbovirus infections have been identified – West Nile Fever, Sindbis, Tahyna, Batai, Uukuniemi and Bhanja. The dominant types of arboviruses were Sindbis and Tahyna, the detection rate of which is 30.5 ± 4.5 and 26.2 ± 4.4%, respectively (χ2=0.56; P>0.05), detection of other types did not exceed 10.4 ± 2.9% (χ2=9.21; Р<0.01). The level of seropositivity depended on the condition of the residents at the time of blood sampling. Comparative evaluation of the identified symptoms in seropositive residents and their interpretation allows to identify risk groups, which is advisable for reducing serological studies and identifying seropositive patients more targetedly. It has been established that the most effective infection occurs in May–June and September–October, when the activity of mosquitoes and the density of their settlement in residential premises and other biotopes in the human habitat is the highest. Conclusion. The study of the seasonality of infection of residents with arbovirus in epidemiological terms is very important, as it allows planning and implementing appropriate preventive measures. Based on the data obtained, it can be argued that the most effective infection of residents occurs in May–June and September–October, when the activity of mosquitoes and their density in residential premises and other biotopes in the habitat of residents is the highest. Infection can also occur in summer, late autumn and early spring, but it is not very effective. Therefore, to reduce the risk of infection of residents, it is advisable to carry out anti-mosquito measures, taking into account the seasonal activity of mosquitoes
