“…Month wise distribution of dengue and chikungunya cases in this study shown a gradual increase from July month onwards which is in concurrence with other outbreaks reported from India [25,26]. In this study the correlation between incidence of arboviral infections and monsoon season was clearly evident and it has been also supported in previous studies [27,28]. Sudden climate change, urbanization, extensive agriculture, migration of humans and animals, mass gathering events, development of air transport etc.…”

Newly emerging or re-emerging infections are posing continuous threat to both public health system and clinical care globally. The emergence of infections especially caused by arboviruses can be linked to several mechanisms which include geographical expansion linked to human development and transportation, global warming, enhanced transmission in peridomestic area and close proximity of human habitations to domestic as well as wild animals. The co-circulation of Dengue, Chikungunya and Zika is a matter of public health priority due to the fact that they are transmitted by the same vector as well as increase in the number of reported cases of severe dengue, postchikungunya chronic joint disease and microcephaly related to Zika virus disease. The study was designed to estimate the prevalence of these arboviral infections in Odisha. About 5198 cases presenting with common clinical symptoms of fever, arthralgia, headache, myalgia and malaise were screened during 2016-2019. A total of 42.2% patients tested positive for dengue NS1 antigen (n = 4154), 30.2% for dengue IgM (n = 2161) and 14.3% for chikungunya IgM (n = 1816). A total of 1684 samples were subjected to Zika RT-PCR and none was tested positive. Peak in the numbers of dengue/ chikungunya cases was evident in the post-monsoon months of July -October. Circulation of all four serotypes of dengue i.e. DEN 1, 2, 3, and 4 was noticed in the state. Molecular investigation of suspected Chik cases in early phases showed circulation of Eastern Central Southern African genotype (E1:226A). There is dearth of knowledge about disease severity during arbovirus co-infections and importance of adequate management of patients at an early stage residing in risk areas. It is the first study in Odisha to study the pattern and status of these three arboviral diseases Dengue, Chikungunya and Zika. The outcome of this study will help in focusing and improvement of existing surveillance systems and vector control tools, as well as on the development of suitable antiviral agents and formulating candidate vaccine.

“…Generally, the people living in rural, tribal and urban slum areas are high-risk groups who are more prone to develop VBDs as they belong to a low socioeconomic group. [2] Malaria as such is a major health concern among all VBD, since the majority of population resides in malaria-endemic areas and 80% of malaria reported in the country is confined to areas such as tribal, hilly, difficult and inaccessible areas. The annual report data recorded 844,558 cases and 194 deaths in 2017.…”

Background: In India, Vector-Borne Diseases (VBD) account for the majority of communicable illnesses. They account for 17% of the projected worldwide burden of all infectious illnesses, posing serious public health issues and impeding the country's socio-economic growth. To make a significant change in society, it is vital to increase the knowledge and attitudes of school students who serve as effective whistle-blowers between community and health educators. Hence the present study was undertaken. Methodology: Descriptive cross-sectional study including 194 secondary school students of rural Mandya. Students who were present and willing to participate were included. A pre-tested structured questionnaire was used to obtain their knowledge and attitude towards VBD. The data obtained before and after the health education was analysed using the McNemar X2 test and Wilcoxon signed-rank test. Results: In the pre-test, 6.2% and 93.8% of the participants have obtained average and poor knowledge scores respectively. A statistically significant improvement in the knowledge score was seen after the health education (Z=-11.91, p<0.001). About attitude, 89.2% had a very good attitude, 9.8% had good and 1.0% had a poor attitude towards vector-borne diseases. However, after health education, it was observed that betterment in the attitude of the students. (Z= -2.63, p=0.009). Conclusion: A significant improvement in the knowledge and attitude towards VBD among the study population was observed after the health education.

“…Arthropod‐borne infectious diseases are considered to be one of the major contributors to global mortality and disability 1 . In India, every year during the monsoon and post‐monsoon period, a large number of individuals get affected with Dengue and Chikungunya, which almost occur in epidemic proportion causing significant morbidity and mortality 2 . An upsurge of all these infections during these periods can impose significant challenges to the healthcare system.…”

For the past several decades, dengue fever has been emerging in epidemic proportions in several regions of the world. During August-September 2019, an increasing number of fever cases were being reported from some areas of North 24 Parganas district of West Bengal, India. Accordingly, outbreak investigation of fever cases from these affected areas of Bongoan, Barasat, and Habra was carried out. To characterize clinical and biochemical features of fever cases as well as to investigate the utility of CRP as a Dengue severity marker in resource-limited settings. We systematically enrolled 108 patients from the affected region of North 24 Parganas. Standard diagnostic assays along with routine serological and biochemical parameters were performed. Of the 108 patients, 77 (71%) were confirmed with Dengue infection followed by 22 (20%) DENV seronegative and 9 (8%) coinfected DENV cases. Among the 77 confirmed Dengue patients, 53 (69%) had primary infection while 24 (31%) had secondary infection. Among the DENV clinical symptoms, fever (r = 0.50; p = 0.004), headache (r = 0.40; p = 0.03) and abdominal pain (r = −0.40; p = 0.02) were found to bear significant correlation with DENV viral load. The predominant circulating serotype was found to be DENV2. CRP Dengue severity cut-off level of 10.15 mg/L (AUC: 0.85; 86% sensitivity, 77% specificity) was obtained. CRP had correlation with viral load (r = 0.4, p = 0.05) within febrile phase of infection. The performance of biomarkers can be influenced by local epidemiology, geography, and several patient factors, therefore, CRP Dengue severity cut-off value may be region-specific. This study for the first time attempts to estimate CRP Dengue severity cut-off value based on routine immunoturbidometric evaluation from Dengue Hyperendemic zones of
