Epidemiological Situation

Aim. To describe clinical and epidemiological situation of the massive increase of cases of vector-borne infections and the level of preventive and antiepidemic measures in the Archangelsk region over the last decade. Methods. Retrospective, longitudinal study investigated ten-year incidence of vector-borne infections, vaccination of the population and the amount of disinfection measures in the region over the last decade. Results of a survey of 232 citizens, who were referred for vaccination against tick-borne encephalitis, are listed. The study included 101 patients with tick-borne encephalitis, 19 of which had concomitant a tick-borne Lyme disease, and 21 patients with tularemia treated in infectious hospitals of Archangelsk between 2011 to 2014. Results. Observations performed over the last decade showed marked increase in the incidence of vector-borne infections among the population of the Archangelsk region Levels of immunization against tick-borne encephalitis has also increased, level of vaccination against tularemia was unstable. Amounts of disinsectization measures tends to increase, but the number of people bitten by ticks also progressively increases. None of patients diagnosed with tick-borne encephalitis and tularemia who got the disease in the Archangelsk region had been previously vaccinated. The survey of 232 citizens showed sustainable motivation for vaccination, therefore, regional program for children and adult vaccination should be facilitated, considering the increasing incidence of vector-borne infections in non-vaccinated subjects. Predominant clinical forms were feverish and severe focal for tick-borne encephalitis, erythema for Lyme disease and bubonic for tularemia. Due to climate change, incidence of vector-borne infections over the last decade was on stable upward trend with high share of severe forms and high risk for progredient clinical course. Conclusion. Preventive and antiepidemic measures in the Archangelsk region over the last decade tend to increase, but are still not enough effective, as do not lead to a significant reduction of incidence.

The Impact

Tick-borne infectious diseases can affect many tissues and organs including bone, one of the most multifunctional structures in the human body. There is a scarcity of data regarding the impact of tick-borne pathogens on bone. The aim of this review was to survey existing research literature on this topic. The search was performed using PubMed and Google Scholar search engines. From our search, we were able to find evidence of eight tick-borne diseases (Anaplasmosis, Ehrlichiosis, Babesiosis, Lyme disease, Bourbon virus disease, Colorado tick fever disease, Tick-borne encephalitis, and Crimean–Congo hemorrhagic fever) affecting the bone. Pathological bone effects most commonly associated with tick-borne infections were disruption of bone marrow function and bone loss. Most research to date on the effects of tick-borne pathogen infections on bone has been quite preliminary. Further investigation of this topic is warranted.

The most of ixodes ticks in Tula region belongs to the group of pasture mites. It is generally accepted to estimate the tick’s contamination by the tick-borne encephalitis virus and raoueti inducing Lyme Borellia. The aim of the present work was to educe the aetiologic agents of the set of potentially-enable infections out of ticks Dermacentor reticulatus, Ixodes ricinus and Ixodes сrenulatus collected at the different terrains of Tula Region by PCR method. The results: a considerable number of pathogenic rickettsiae R. raoultii was educes from the ticks D. reticulatus, which including them as the component of mixed infection together with the human monocytic ehrlichiosis agent. R. raoultii was determined in more than a half of the cases in ticks I. ricinus including the mixed infection together with ticks’ borreliosis virus and Kemerovo fever agent. Conclusion. The reasons, induced the quantity changes of the ticks’ distribution at Tula Region terrains, apparently promote the rise in frequency of the ticks contamination with the agents of herd tick-transmissive infection. It demand an infectiologist’s attention rise and dictate the necessity of the above mentioned diseases monitoring as well as Fr. tularensis, the tick-borne encephalitis virus and Lyme disease.

Epidemiological Situation

In this paper an epidemiological situation regarding tick-borne encephalitis at children in Tomsk region is analyzed. It is noted that Tomsk region is an endemic center of tick-borne encephalitis with cyclic variations by subareas. The total number of children with tick-borne encephalitis in the south and middle subareas is greater then in the northern subarea. The number of diseased children depended on the number of persons went to seroprophylaxis stations after the tick suction, on the tick number and duration of epidemiological season. Vaccination, accessible and free specific seroprophylaxis of the population promoted the step-by-step increase of feverish and meningeal form part and the decrease of focal tick-borne encephalitis form part.

Lyme disease is one of the most frequent tick-borne diseases worldwide, it can be multi-systemic and insidious, in particular when it shows a chronic course.In recent years co-infections represent an emerging issue in Lyme disease spectrum because in addition toBorrelia burgdorferi slmany other potential pathogens may be transmitted by hard ticks Ixodes species. The main co-infections found in Lyme disease described in this review are represented byAnaplasma phagocytophilum, Babesia species, Bartonella species, Rickettsiae species and tick-borne encephalitis virus. For each single co-infecting micro-organism, clinical features, diagnostic issues and therapeutical approaches are discussed.Co-infections represent an emerging problem because they might exacerbate Lyme disease clinical features, they can also mimic Lyme borreliosis sharing common manifestations, and eventually they can change the course of the disease itself.The presence of one or more co-infecting agent during the course of Lyme disease may represent an issue especially in endemic areas for tick-borne diseases and in people occupationally exposed.The aim of this review is to summarize the more important co-infections in patients with Lyme disease and to discuss their importance in the disease process.

AbstractTick-borne infections—including tick-borne encephalitis viruses, represented in the United States by rare infections with Powassan and deer tick viruses, and more often Lyme disease—are of increasing importance to neurologists. Lyme neuroborreliosis (LNB) causes all or part of a triad including meningitis, radiculoneuritis, and cranial neuritis. Rarely, parenchymal brain and spinal cord involvement occur, with focal findings on examination and magnetic resonance imaging (MRI). LNB diagnosis requires plausible exposure, objective evidence of nervous system involvement, and, generally, positive two-tier serology. Central nervous system (CNS) LNB is almost always accompanied by abnormal cerebrospinal fluid (CSF) (cells, protein), often with intrathecal antibody production, which is determined by concentration-adjusted comparison of serum and CSF antibody. Measuring CSF antibody in isolation and nucleic acid-based testing of CSF are not useful in LNB and should be avoided. LNB treatment is highly effective with a 2- to 3-week course of antibiotics. Increasing evidence suggests that LNB not involving the CNS parenchyma can be treated successfully with oral doxycycline.

Epidemiological Situation

This paper characterizes the current epidemiological situation of tick-borne encephalitis in the Tomsk region. There has been a decrease in the incidence of TBE for 10 years. There was made an attempt to typify the epidemiological situation of tick-borne encephalitis nidus on the basis of analysis of epidemiological data of the recent years (2011-2020) in the context of administrative territories of Tomsk region. The typification of the foci of TBE was carried out in the context of the administrative territories of the region. Areas of high, medium, low risk of TBE infection are identified. The territories of the city of Tomsk and the Tomsk region, where the maximum infection rates are recorded (66-88 cases per year), are referred to the high-risk zone. Keywords: monitoring, morbidity, tick-borne encephalitis, natural focal infections, intensive indicator.

Epidemiological Situation

INTRODUCTION. Lyme disease is the most common tick-borne disease, caused by spirochetes of the genus Borrelia, transmitted by ticks of the Ixodes genus. According to ECDC, Poland should be considered as an endemic area. The risk of Lyme disease incidence in-creases with tick habitats increase, which is a response to environmental factors and climate change. AIM OF THE STUDY. The aim of the study is to assess the epidemiological situation of Lyme disease in Poland in 2018 compared to the situation in previous years. MATERIAL AND METHODS. The epidemiological situation of Lyme disease in Poland was assessed on the basis of the data sent to NIPH-NIH by voivodeship sanitary-epidemiological stations and published in the bulletin ‘Infectious diseases and poisoning in Poland in 2018’ . RESULTS. In 2018; 20,150 Lyme disease cases was registered, 2,124 people were hospitalized. You can also see an increase in cases in the second and third quarter in favor of the fourth quarter. The epidemiological situation in Western European countries is similar to the situation in Poland. SUMMARY AND CONCLUSION. The inability to determine the clear trend of the epidemiological situation in Poland indicates the sensitivity of the surveillance system, but also the difficulty in new cases diagnosis. You can also see a decrease in the number of cases, which may be a sign of having the right tools or experience in the Lyme disease diagnosis.

Epidemiological Situation

ABSTRACT INTRODUCTION. Meningitis are the most common form of the nervous system infectious diseases. There are meningitis and/or encephalitis with bacterial and viral etiology. In epidemiological surveillance are highlighted meningitis and/or encephalitis caused by N. meningitidis, S. pneumoniae, H. influenzae and tick-borne encephalitis virus. Because vaccinations against these agents are common. AIM OF THE STUDY. The aim of the study is to assess the epidemiological situation of meningitis and encephalitis in Poland in 2017. MATERIAL AND METHODS. The epidemiological situation of meningitis and encephalitis in Poland was assessed on data from the annual bulletin “Infectious diseases and poisoning in Poland in 2017” and “Vaccinations in Poland in 2017”. (MP Czarkowski et al., Warsaw 2018, NIZP-PZH, GIS). RESULTS. In 2017 were registered 2 095 cases of meningitis and/or encephalitis in Poland. It means a 10.8% decrease in meningitis and/or encephalitis in Poland compared to 2016. With a general decrease in the number of infections of bacterial etiology, the number of cases of meningitis and/or encephalitis of S. pneumoniae, H. influenzae type B cases reported remains at the same level similar to last year. In contrast, the number of cases of etiology of N. meningitidis shows an increase of 25.4% compared to the previous year. Among all cases 57.9% were viral infections. In comparison to 2016 means a decrease in the percentage share of viral infections by 1.2 percentage points for bacterial infections. Among laboratory confirmed cases of neuroinfection with established etiology, the incidence caused by Neisseria miningitidis (122 cases), Streptococcus pneumoniae (171 cases) and tick-borne encephalitis (283 cases) are the most prevalent. SUMMARY AND CONCLUSION. There is a general downward trend in the number of meningitis and/or encephalitis cases, which may be due to introducing mandatory vaccination against S. pneumoniae. It can also mean an improvement in diagnostics given the decrease in unspecified meningitis and/or encephalitis. However meningitis and/or encephalitis remain a challenge for healthcare and epidemiological surveillance institutions.
