Introduction: Emerging and re-emerging viral diseases are a major threat to public health. Odisha, being one of the coastal states in the country, reports many viral illnesses due to its typical geographical location. This study focuses on the prevalence of different viral diseases in the state of Odisha, India, from 2010-2017. Material and Methods: A total of 43,397 patients with clinical suspicion of viral diseases were screened for different viral etiologies during 2010-2017. The laboratory diagnosis was conducted by serology (ELISA) and RT-PCR for 24 different viruses, i.e., dengue, chikungunya, Japanese encephalitis, hepatitis A virus, hepatitis E virus, hepatitis B virus, hepatitis C virus, rotavirus, herpes simplex virus-1 and herpes simplex virus-2, Epstein- Barr virus, cytomegalovirus, and respiratory viruses. Patients were enrolled from sporadic hospital admissions and outbreaks under different categories as per clinical diagnoses like fever with rash, diarrhoea, encephalitis, jaundice, respiratory illness, and fever of unknown etiology. Results: The majority of patients belonged to exanthematous group, i.e., fever with rash (32.24%). The number of males was more in all categories except fever with rash, where females (53.34%) were more. Children <16 years of age were found to be the predominant age group for suspected viral diarrhoea (85.26%), encephalitis (76.96%), fever of unknown origin (40.16%), and respiratory infections (27.23%). Conclusion: Not only vector-borne diseases pose a threat to the Odisha state, but other viral illnesses have also emerged. This detailed report of different viral diseases in the state of Odisha will support public health management. [ABSTRACT FROM AUTHOR]

Compared the "Diagnostic and Statistical Manual of Mental Disorders" Major Depressive Disorder (MDD) diagnostic interview information from Hong Kong and U.S. adolescents. Results suggested that adolescent MDD was as prevalent in Hog Kong as in the United States and that "subthreshold" depression was not a benign condition. Comparison of symptomatic patterns in the two cultures showed cultural influences on expressions of distress. (Contains references.) (SM)

Despite consistent public health efforts, the burden of viral disease in India remains high. The present study was undertaken to understand the aetiology, frequency and distribution of viral disease outbreaks in the state of Odisha between 2010 and 2019. This was a prospective study conducted at the Virology Research and Diagnostic Laboratory located at ICMR-Regional Medical Research Centre, Bhubaneswar, Odisha, wherein all the outbreaks of viral aetiologies were investigated and analysed to provide a comprehensive picture of the state of viral disease outbreaks in the region. A total of 191 suspected viral outbreaks were investigated by the team from VRDL during September 2010 and September 2019 reported from all the 30 districts of Odisha. Annual number of suspected cases ranged from 185 to 1002. The most commonly suspected outbreaks were of viral hepatitis (55 outbreaks; 1223 cases) followed by dengue (45 outbreaks; 1185 cases), chickenpox (30 outbreaks; 421 cases), viral encephalitis (27 outbreaks; 930 cases), measles (23 outbreaks; 464 cases), chikungunya (10 outbreaks; 593 cases) and rubella (1 outbreak; 60). The outbreaks peaked in frequency and intensity during the months of July and September. The epidemiology of viral disease outbreaks in the region is presented in the study. Health system preparedness based on evidence is essential for early detection and adequate response to such viral outbreaks. [ABSTRACT FROM AUTHOR]

During the early stage of an epidemic, timely and reliable estimation of the severity of infections are important for predicting the impact that the influenza viruses will have in the population. We obtained age-specific deaths and hospitalizations for patients with laboratory-confirmed H1N1pdm09 infections from June 2009 to December 2009 in Hong Kong. We retrospectively obtained the real-time estimates of the hospitalization fatality risk (HFR), using crude estimation or allowing for right-censoring for final status in some patients. Models accounting for right-censoring performed better than models without adjustments. The risk of deaths in hospitalized patients with confirmed H1N1pdm09 increased with age. Reliable estimates of the HFR could be obtained before the peak of the first wave of H1N1pdm09 in young and middle-aged adults but after the peak in the elderly. In the next influenza pandemic, timely estimation of the HFR will contribute to risk assessment and disease control. [ABSTRACT FROM AUTHOR]
