Epidemiological Situation

West Nilefever (WNF) is the most important arbovirus infectionfor the Volgograd region. The observed decrease in the WNF incidence from 2001 to 2006, in 2008 and2009, the reducing the number ofsevere forms ofdiseases only give evidence ofa temporary regression of the epidemic process in the territory of the Volgograd region. In the territory of the Volgograd region there are prerequisites and harbingers of the complication of epidemiological situation on West Nile fever. The aim of the performed in the Volgograd region epidemiological surveillance for WNF is to provide the information necessary and sufficient for the analysis of the epidemiological situation, as well as to determine the direction of policy and activities in public health and in making management decisions.

Cases of West Nile neuroinvasive disease (WNND) in Spain increased in summer 2020. Here we report on this increase and the local, regional and national public health measures taken in response. We analysed data from regional surveillance networks and the National Epidemiological Surveillance Network, both for human and animal West Nile virus (WNV) infection. During the 2020 season, a total of 77 human cases of WNV infection (median age 65 years; 60% males) were detected in the south-west of Spain; 72 (94%) of these cases developed WNND, presenting as meningoencephalitis, seven of which were fatal. In the previous two decades, only six human cases of WNND were detected in Spain. Reduced activities for vector control this season, together with other factors, might have contributed to the massive increase. Public health measures including vector control, campaigns to raise awareness among physicians and the general population, and interventions to ensure the safety of donations of blood products, organs, cells and tissues were effective to reduce transmission. Going forward, maintenance of vector control activities and an update of the vector-borne diseases response plan in Spain is needed.

AbstractWe aimed to describe the clinical characteristics of West Nile patients reported in Québec in 2012 and 2013 and to document physical, mental and functional status 24 months after symptom onset according to illness severity. The cases were recruited by a public health professional. Data were collected from public health files, medical records and two standardised phone questionnaires: the Short Form-36 and the Instrumental Activities of Daily Living. In all, 92 persons participated in the study (25 had West Nile fever (WNF), 18 had meningitis and 49 had encephalitis). Encephalitis participants were older, had more underlying medical conditions, more neurological symptoms, worse hospital course and higher lethality than meningitis or WNF participants. Nearly half of the surviving hospitalised encephalitis patients required extra support upon discharge. At 24-month follow-up, encephalitis and meningitis patients had a lower score in two domains of the mental component: mental health and social functioning (P = 0.0025 and 0.0297, respectively) compared with the norms based on age- and sex-matched Canadians. Physical status was not affected by West Nile virus (WNV) infection. In addition, 5/36 (15%) of encephalitis, 1/17 (6%) of meningitis and 1/23 (5%) of WNF participants had new functional limitations 24 months after symptom onset. In summary, mental and functional sequelae in encephalitis patients are likely to represent a source of long-term morbidity. Preventive measures should target patients at higher risk of severe illness after WNV infection.

Aim. Clinical-epidemiological characteristic of West Nile fever on the territory of Krasnodar Region in multi-year dynamics. Materials and methods. Manifestations of epidemic process and clinical symptoms of West Nile fever (WNF) on the territory of Krasnodar Region were analyzed retrospectively from 1988 to 2013. Results of epidemiologic observations with inclusion of monitoring of arbovirus circulation, carried out by Prichernomorskaya Station of Plague Control and Centre of Hygiene and Epidemiology in Krasnodar Region were used. Clinical course of verified WNF was studied in 62 patients, treated in the Specialized Clinical Infectious Hospital ofKrasnodar in 1999 - 2012. Results. Clinical-epidemiologic characteristic of cases of West Nile fever morbidity on the territory of Krasnodar Region is presented. The presence of acting foci of arbovirus infections was noted. Clinical signs of the disease are established, patients allocated into groups that require examination for West Nile fever. Conclusion. Complex of entomologic-virologic monitoring, prophylactic and counter-epidemic measures was determined, that allow to prevent emergence of dangerous epidemiologic manifestations of foci of the disease in the future.

Purpose: analysis of the arbovirus infections incidence in the south of the European part of the Russian Federation in 2015–2019.Materials and methods. Data from statistical documentation (epidemiological examination of the infectious disease cases, reports on the arbovirus infections incidence) reported by Departments of Rospotrebnadzor to Scientific and Methodological Center for monitoring pathogens of infectious and parasitic diseases of 1–3 risk groups for subjects of the North Caucasian and Southern Federal Districts were analyzed. The obtained data were processed using Microsoft Excel 2010 program.Results. In the south of the European part of the Russian Federation Crimean-Congo hemorrhagic fever (CCHF), West Nile fever (WNF), tick-borne viral encephalitis and dengue fever cases are registered annually.An expansion of the territory with registered epidemic manifestations of CCHF and WNF was noted, reflecting an increase in the area of circulation of their pathogens. An expansion of CCHF and WNF epidemic season with the involvement into the epidemic process of people from all age groups including young children was observed. Significant increase in number of imported cases of dengue fever was documented. Markers of tick-borne viral encephalitis, Batai, Inko, Sindbis, and Tyaginya fevers were detected in residents of a number of territories. A high levels of population humoral immunity to West Nile, Batai, Inko, Sindbis Tyaginya, Ukuniemi, Bhanja, Dkhori viruses were identified in the Astrakhan region.Conclusion. The data obtained indicate the need for epidemiological surveillance both for arbovirus infections with a pronounced epidemiological and clinical manifestations, and for infections, the proportion of which in the structure of infectious pathology in southern Russia has not been sufficiently studied, but carrying a potential risk of spreading.

The trend towards an increase in the West Nile fever incidence among the population in the Russian Federation, recorded in the season of 2018, continued and led to a significant increase in the incidence in 2019 (the indicator was 2 times higher than the long-term average). The features of manifestations of the epidemiological process of WNF in 2019 were identified: early registration of cases of the disease, activation of natural and natural-anthropourgic foci in the Southern Federal District (90 % of the total incidence in the Russian Federation), an increase in the share of neuro-invasive forms, dominance of patients aged 50 and older in the structure of the incidence, late epidemic season ending. It was established that in the season of 2019, the lineage 2 of WNV circulated in the European part of Russia. In the Volgograd Region, simultaneous presence of the West Nile virus and Sindbis virus in mosquitoes Culex pipiens and Culex modestus was identified. It was shown that the most significant factors for predicting the epidemiological situation on West Nile fever in the Volgograd Region are the average seasonal summer air temperature and monthly average indicators of relative humidity in the spring and summer periods, and the average monthly air temperatures in the spring and summer in the Rostov Region. In the Astrakhan Region, a significant correlation dependence of the influence of the considered factors on the incidence of the population has not been established. The forecast of the development of epidemic situation in 2020 does not exclude a possible increase in the incidence in the territories of the European part of Russia, endemic for West Nile fever, and the occurrence of local outbreaks in individual constituent entities, if the complex of climatic conditions and social factors favorable for West Nile virus coincide.
