West Nile virus infections in Hungary: Epidemiological update and phylogenetic analysis of the Hungarian virus strains between 2015 and 2022.

Following the introduction of the West Nile virus (WNV) into Hungary in 2004, it has shortly become one of the most important human arbovirus infections, with a gradually increasing number of cases. The study aimed to summarize the current epidemiological situation in Hungary and sequence the WNV PCR-positive clinical specimens and virus isolates by next-generation whole genome sequencing (NGS) to obtain a detailed phylogenetic analysis of the circulating virus strains. Whole blood and urine samples from confirmed WNV-infected patients and WNV isolates were investigated by reverse transcription PCR assays. Genome sequencing was carried out by Sanger-method, followed by NGS on the Illumina MiSeq platform. Altogether 499 human infections were diagnosed between 2004 and 2022. A particularly remarkable increase in human WNV infections was observed in 2018, while the number of reported cases significantly decreased during the COVID-19 pandemic. Between 2015 and 2022, 15 WNV isolates, and 10 PCR-positive clinical specimens were investigated by NGS. Phylogenetic analysis revealed that the major European WNV lineage 2 clades, namely the Eastern European (or Russian) and the Central European (or Hungarian) clades, are presented in Hungary. Strains of the Balkan and other European clusters within the Central European clade are co-circulating in the country, following a characteristic geographical distribution. In Hungary, the presence and co-circulation of multiple lineage 2 WNV strains could be identified in the last few years. Therefore, in light of the 2018 WNV outbreak, sequence-based typing of the currently circulating strains could highly support outbreak investigations.

A COVID-19-pandémia harmadik hullámának hatása a 60 év feletti magyar lakosság életmódjára, mentális és fizikai egészségére.

INTRODUCTION: Elderly population is the most vulnerable group of the COVID-19 pandemic, since they often live with chronic diseases. OBJECTIVE: The goal of our research is to analyze the direct and indirect effects of the pandemic on the Hungarian population over 60 years of age. METHOD: We collected data using the authentic Hungarian translation of the "World-Wide FINGERS SARS-CoV-2 Survey" between 1st of February and 1st of June 2021. RESULTS: Our study included 431 people with a low rate of COVID infection (6%). The most marked changes were the increase in the use of digital services in 71%, increased feeling of loneliness in 46%, decrease in subjective sleep quality in 47%, and reduced contact with friends and relatives in 80% of the respondents. Eight-six percent of participants had at least one chronic illness and 23% missed an illness-related medical visit during the pandemic. In 45%, the subjective quality of life deteriorated and 25% reported impairment of memory functions. DISCUSSION: Participants became socially isolated during the pandemic having a significant negative impact on their way of life. The changes in physical and mental health are likely to be reflected in an increased incidence and accelerated progression of age-related diseases in the elderly. CONCLUSION: In order to reduce the direct and indirect harmful effects of the COVID-19 pandemic, it is of paramount importance to know how the pandemic and the following restrictions affect the behavior and lifestyle of the elderly as well as the care of patients living with chronic diseases.

[Can we influence the negative drug attitude? Interpretation of the rejection of COVID-19 vaccine in the light of results of a pilot study]. / Befolyásolható-e a negatív gyógyszerszedési attitud? A Covid-19-vakcinát elutasító magatartás interpretációja egy elokészíto vizsgálat eredményeinek tükrében.

Background and purpose: Vaccination refusal is a serious obstacle to minimizing the spread of COVID-19. Nevertheless, the rejection of vaccine can be considered the result of a negative attitude towards medical treatment, and according to our previously published data, it can be influenced by the underlying affective state. Increased incidence of affective disorders and anxiety could be observed globally during the pandemic, which may have a significant impact on vaccination acceptance. The aim of our pilot study was to determine the association between clinical improvement of affective and neurocognitive symptoms and change of drug attitude and health control beliefs in a sample of psychiatric patients. Methods: A data set of 85 patients with psychiatric disorder has been analysed with the use of Patient's Health Belief Questionnaire on Psychiatric Treatment (PHBQPT) with 5 subscales (Negative Aspect of Medication - NA; Positive Aspect of Medication - PA; Doctor health locus of control- Doctor HLOC; Internal HLOC; Psychological Reactance - PR); Hospital Anxiety Depression Scale (HADS-Anx; HADS-Dep) and neurocognitive tests, such as the Stroop test and the Trail Making Tests. All the tests were performed before and after a 14 days treatment. Paired t-tests and generalized linear models were performed to assess the associations between the variables. Results: The baseline scores of NA and HADS-Anx correlated significantly (p=0.001) and after two weeks of treatment NA decreased (p=0.001), while Doctor HLOC and Internal HLOC increased (p=0.001 and p=0.006). The patients performance of the neurocognitive tests improved (all p<0.05). The reduction of HADS-Anx (p=0.002) and HADS-Dep (p=0.006) scores showed significant associations with the decrease of NA. Increase of the PA score was associated with reduction of HADS-Dep (p=0.028). Improvement of neurocognitive functions had no effect on PHBQPT scores. Conclusion: Important conclusions can be drawn regarding the rejection of the COVID-19 vaccine based on the associations found between the intensity of affective and anxiety symptoms and the attitude towards treatment. Our findings suggest that affective symptoms have a negative influence on the attitude towards treatment and that the improvement of these symptoms can facilitate the acceptance of the therapy, regardless of diagnosis. The modest effect of the improvement of neurocognitive functioning on the attitude towards drugs and the significant role of affective-emotional factors suggest that the accep-tance of vaccination probably cannot be facilitated solely with the aid of educational programs. Considering the increasing incidence of affective disorders during the COVID-19 pandemic, the screening of affective and anxiety symptoms and treatment of these disorders could be an important step towards the acceptance of the vaccine. Although psychiatry is not considered as a frontline care unit of the COVID cases, more attention is needed to pay on the availability of mental health services because refuse of vaccine can develop due to affective disorders too.
