Abstract
Background This study was to compare a baseline and endline survey which were conducted to assess the changes in knowledge, attitude and practices about anthrax disease among the communities after One Health intervention for the elimination of human anthrax in an endemic district of Odisha. Methods A total of 2670 respondents were interviewed during the baseline and 2511 for the endline survey using a structured questionnaire by multi-stage sampling method. Descriptive statistics were used and logistic regression was performed to estimate the relationship between the variables and knowledge of anthrax. Results Out of the total participants in the study, males were about 76.25% in baseline and 72.08% in endline and about half of the total respondents were illiterate. Majority of the respondents had reported agriculture as their main occupation during both surveys. More than 50% of the respondents had livestock in their houses and farming was the main purpose for keeping them in both surveys. Around 20.26% of respondents knew about anthrax in baseline which raised to 53.64% after One Health intervention. Almost 21.29% of livestock owners had vaccinated their animals against anthrax disease throughout baseline, which increased to 66.5% during the endline survey. Conclusion This study highlights a significant surge in both knowledge and practices related to anthrax within the community after the implementation of intervention packages based on the One Health approach. The outcome of our study signified the importance of One Health interventions to address the health challenges related to zoonotic diseases in tribal communities. The data could be useful for local Governments to incorporate such an approach in their health policy to eliminate human anthrax.

Abstract
This study presents a rare case of chronic multifocal tubercular osteomyelitis in a 13-year-old boy from Nepal, a high-burden country for tuberculosis (TB). He presented with chronic pain in the lower extremities and had no pre-existing comorbidities. The patient's clinical presentation, diagnostic process, and treatment plan are described. Multifocal skeletal TB, though infrequent, poses diagnostic challenges due to its variable manifestations. This case emphasizes the importance of considering TB in differential diagnoses, especially in endemic regions, necessitating a high index of suspicion. Early detection and treatment align with WHO's "End TB" strategy and Nepal's TB management guidelines, promoting improved outcomes in high-risk populations.

Abstract
INTRODUCTION AND IMPORTANCE Gallbladder tuberculosis (GT) is an extremely rare clinical entity that represents only 1 % of abdominal tuberculosis cases. Preoperatively, most patients are misdiagnosed as chronic cholecystitis or gallbladder malignancy. CASE PRESENTATION We report the case of a 43-year-old patient, whose clinic, imaging and biology were in favor of Gallbladder carcinoma. DISCUSSION The clinical presentation of GT is varied and nonspecific, making the preoperative diagnosis of GT difficult; it may mimic acute cholecystitis to frank malignancy as seen in our case. Preoperatively, GT poses a diagnostic dilemma despite advanced imaging modalities, leading to missed diagnosis. The biology remains non-specific also. The diagnosis is usually made upon histological examination after cholecystectomy. CONCLUSION Even though the clinical presentation and the radiology are aspecific and misleading, It seems to us justified to evoke the diagnosis of tuberculosis faced with such a presentation, especially if the patient comes from a tuberculosis-endemic country. Diagnosis is made upon histopathological examination.

Abstract
The human monkeypox virus (MPXV) was first identified in 1959. Since then, the incidence of the disease has been sporadic. The endemic regions were identified in Africa's central and western areas. However, the infection started to spread in 2017 to non-endemic regions such as North and South America, Europe, and Asia. Since May 2022, the non-endemic areas reported 62,635 till 20th September 2022. Although the monkeypox virus has a mortality of ≥ 10%, it showed only 82 mortalities worldwide in 2022. The common symptoms include chills, fever, fatigue, and skin lesions, and the complications include secondary respiratory tract infections, encephalitis, blindness, and severe diarrhea. The factors responsible for spreading the virus include improper handling and consumption of infected bushmeat, unprotected sexual intercourse, contact with an infected person, no smallpox vaccination, improper hygiene, lower diagnostic capacity, and strong travel history from the endemic regions. The therapeutic strategy is symptom-based treatment and supportive care. Antivirals and vaccines such as Tecovirimat, Brincidofovir, Cidofovir, Imvamune, and ACAM2000 have shown promising results. The primary purpose of the review is to perform an epidemiological study and investigate the pathobiology, diagnosis, prevention, treatment, and some associated complications of the monkeypox virus in 2022.

Abstract
BACKGROUND This study is a baseline survey to assess the knowledge, attitude and practices with regards to the anthrax disease among the communities before demonstrating a One Health approach for elimination of human anthrax in an endemic district of Odisha. A total of 2670 respondents from 112 villages of 14 blocks were interviewed for the study using a structured questionnaire by multi-stage sampling method. Descriptive statistics were reported and logistic regression was performed to estimate the relationship between the variables and knowledge of anthrax. RESULT Out of 2670 participants in the study, 76.25% were male and about half were illiterate. Most of the respondents (54.19%) were involved in agriculture as an occupation. 71% of the respondents had livestock in their houses and farming was the main purpose for keeping the livestock. Only one-fifth of the respondents (20.26%) knew about anthrax and a majority of them have come across the disease during community outbreaks. Almost 25.9% of livestock owners had knowledge about vaccination against anthrax disease although 83.4% of the livestock owners disposed the animal carcass by burial method. CONCLUSION The study findings indicated that the community members had poor knowledge of cause, symptoms, transmission and prevention of anthrax disease which may be improved by a One Health approach.

Abstract
The current study aimed to identify correlative and regressive dependencies between the water iodine concentration and the levels of TSH (thyroid-stimulating hormone), thyroglobulin antibodies (TgAbs), and thyroid peroxidase (TPOAb) in the serum of 168 in patients (34 men and 134 women) with a hypothyroid form of Hashimoto's thyroiditis who use water from the supply network and individual wells. Based on the water iodine concentration, low and moderate degrees of iodine endemia in the location of the patients were determined. In the groups of men and women using water from different water supply sources, there were direct correlations between the water iodine concentrations and the TgAbs and TPOAb titers as well as an inverse dependence between iodine and TSH levels. Multivariate regressive analysis indicated that TgAb and TSH in the group of women using water from a supply network and TPOAb titers in the group of women using well water were independent factors associated with water iodine concentrations. Statistically significant correlations and regressive dependencies between the water iodine concentrations and the biomarkers of the thyroid status of the patients indicate the risk of Hashimoto's thyroiditis progression, especially among women with additional iodine intake.

Abstract
Given the nationwide distribution of the vector, Ixodes ricinus, both neuroborreliosis and tick-borne encephalitis (TBE) might be expected to occur throughout Germany. However, cases of neuroborreliosis and TBE have so far only been reported in certain German states and counties. The aim of this survey therefore was to investigate the possible occurrence of TBE in regions not designated as known risk areas and the spread and incidence of neuroborreliosis throughout Germany. Data were collected by means of a questionnaire which was sent to 305 neurological clinics in Germany. Only twenty-two of them (7.2%) participated in a prospective, and 52 (17%) in a retrospective survey, therefore the significance of the study is limited. Cases of TBE were detected in five counties (Barnim, Dessau-Roßlau, Western Pomerania-Ruegen, Saarbruecken, Uckermark) that were not known so far as areas of risk according to the definition of the German Robert-Koch-Institute (RKI). The median incidence of TBE in various counties was 1.24 cases with a range from 0.19 to 20 cases per 100,000 inhabitants/year. Illnesses from neuroborreliosis were reported from all 61 counties, where clinics participated in the study. The incidence here varied between 0.19 and 23.4 cases with a median of 3.0 cases per 100,000 inhabitants/year. In areas where both diseases occurred, their incidence differed greatly from each other. The survey shows the occurrence of TBE in several counties in eastern Germany that are not defined as risk areas by the RKI and an incidence of neuroborreliosis in Germany that is significantly higher than reported to the public health authorities.

Abstract
Background Severe fever with thrombocytopenia syndrome (SFTS) is a typical tick-borne, natural focal disease. The natural foci of SFTS were considered to exist in hilly and mountainous areas before 2015. A cluster of 3 patients exposed to a patient with a fulminant disease consistent with SFTS occurred from July to August 2015 in Dongtai County, which is characterized by alluvial plains; this prompted investigation. Methods The epidemiological, clinical, and laboratory features of 4 patients in the cluster were analyzed. Serum samples from the indigenous healthy population and native domesticated animals were collected to conduct laboratory tests, along with small wild animals and ticks. Results In 3 secondary case patients, high fever, thrombocytopenia and leukopenia developed within 8-13 days after contact with blood or bloody secretions from the index patient; SFTS was then diagnosed by means of reverse-transcription polymerase chain reaction. Genomic sequencing and analysis of S and L segments of 2 viral strains isolated from 2 secondary case patients showed that they shared 99.8%-99.9% homology in nucleotide sequence. The seroprevalences among indigenous healthy population, native livestock, native poultry, and small wild animals was 0.74%, 17.54%, 6.67%, and 1.12%, respectively. Three questing ticks, 61 feeding ticks, and 178 small wild animals were collected in August 2015. Survey on tick density and seasonal fluctuation in 2016 showed that ticks were active from March to October. All ticks were identified as Haemaphysalis longicornis. Severe fever with thrombocytopenia bunyavirus (SFTSV)-specific RNA was detected in the ticks collected in 2016, and the minimum SFTSV infection rate in these ticks was 0.54% (1 of 185).Wild mammals and ticks collected in August 2015 tested negative for SFTSV-specific RNA. Conclusions Aside from hilly or mountainous area, a coastal plain was identified as the natural foci of SFTSV in Dongtai County, China. The involvement of migration in the evolution of SFTSV might lead to a transregional transmission event of SFTSV.

Abstract
Rickettsiosis are emerging or re-emerging diseases, with a worldwide distribution associated to transmission by arthropod vectors. Rickettsia species belong to the spotted fever group (SFG) and are transmitted by hard ticks (Acari: Ixodidae) that may act as vectors and reservoirs. This study carried out a molecular detection of Rickettsia from 7 species of the family Ixodidae collected from domestic hosts by PCR amplification of fragments of the citrate synthase "gltA" gene and outer membrane protein "ompA" gene. Of the 204 samples analyzed, 11.3% (23) were positive for rickettsial infection. Three Rickettsia species belonging to the SFG were found, constituting the first reports of Rickettsia rickettsii in 2 departments of Colombia. Furthermore, we confirmed the first occurrence of Candidatus Rickettsia andeanae in Colombia, a species with an unknown pathogenic role in humans. These results raise awareness regarding the need to increase epidemiological control measures, as well as to consider new endemic regions in Colombia for Rocky Mountain spotted fever (RMSF).

Abstract
Surveillance systems for rabies in endemic regions are often subject to severe constraints in terms of resources. The World Organisation for Animal Health (OIE) and the World Health Organisation (WHO) propose the use of an active surveillance system to substantiate claims of disease freedom, including rabies. However, many countries do not have the resources to establish active surveillance systems for rabies and the testing of dead dogs poses logistical challenges. This paper explores the potential of using a scenario tree model parameterised with data collected via questionnaires and interviews to estimate the sensitivity of passive surveillance, assessing its potential as a viable low-cost alternative to active surveillance systems. The results of this explorative study illustrated that given a large enough sample size, in this case the entire population of Colombo City, the sensitivity of passive surveillance can be 100% even at a low disease prevalence (0.1%), despite the low sensitivity of individual surveillance components (mean values in the range 4.077×10(-5)-1.834×10(-3) at 1% prevalence). In addition, logistic regression was used to identify factors associated with increased recognition of rabies in dogs and reporting of rabies suspect dogs. Increased recognition was observed amongst dog owners (OR 3.8 (CI, 1.3-10.8)), people previously bitten by dogs (OR 5.9 (CI, 2.2-15.9)) and people who believed they had seen suspect dogs in the past (OR 4.7 (CI, 1.8-12.9)). Increased likelihood of reporting suspect dogs was observed amongst dog owners (OR 5.3 (CI, 1.1-25)). Further work is required to validate the data collection tool and the assumptions made in the model with respect to sample size in order to develop a robust methodology for evaluating passive rabies surveillance.
