Dengue: Arboviral Infection In The World

Discussion
Dengue is now a global threat that has emerged as an important arboviral infection in different geographical regions of the world that supports the growth of mosquitoes. An estimated 50 million people live in dengue endemic countries. Its range exceeds over a hundred tropical and subtropical countries with more than 2.5 billion people at the risk of infection with about 100 million new cases each year worldwide. [18] [1, 19, 20] Dengue infection has been known to be endemic in India for over two centuries as a benign and self-limited disease. In north Indian region it has emerged as major health problem. In recent years, the disease has changed its course manifesting

According to Bihar Health Society report in 2012 seven Bihar districts hit by dengue, three persons were reported to have died and 250 others affected by it. Among the districts affected, Bhagalpur and Patna have reported the maximum number of cases. There are 1800 cases of dengue, including three deaths in the year 2013 in Bihar. According to government estimation Dengue has spread in more than two-third area of the State. This numbers is increasing rapidly and patients are being treated in Government and Private Hospitals .District Rohtas is worsted affected in 2013 with 1127 reported cases. According to Bihar Government estimate Bhabua comes second with 305 cases and The State Capital Patna with 105 cases of Dengue, reported in 2013. (9. http://timesofindia.indiatimes.com/topic/Dengue-Fever.) As we see the data reported from news paper, it is clear that dengue is becoming a deadly disease in Bihar. To determine the real burden of the disease it is urgently required to conduct seroprevalence studies on a broader scale. This is the first study on seroprevalence and serotyping conducted for period of three year from (2012 to 2014) of dengue infection reported

The other serotype present was serotype DEN-2. Concurrent infections with two different dengue virus serotypes is also reported first time in this region during an outbreak .Our results highlight the risks of febrile illness due to the prospect of dengue virus and indicate a large earlier exposure of the people of Patna, Bihar to dengue infection. Young people and males are more disposed to dengue fever according to present febrile cohort study of three year period Dengue infection was most frequent in the post-monsoon season. Further critical analysis is necessary to characterize the current dengue virus circulation patterns and to identify the linked serotypes and genotypes. The government and policy makers urgently need to make extensive efforts towards disease prevention and vector control through biological and/or environmental measures, chemical measures, and education strategies in the community, so that patients seek timely medical care, and knowledge of family dispensers/physicians/general practitioners to identify the admission signs and symptoms of dengue viral infection is strengthened. Moreover a strong campaign would be indispensable to increase local awareness in the population of this area so that they follow all the preventive measures
