Emerging/re-emerging viral diseases & new viruses on the Indian horizon. Indian Journal of Medical Research. 2019 Apr; 149(4): 447-4670971-59160975-9174http://imsear.searo.who.int/handle/123456789/195866Infectious diseases remain as the major causes of human and animal morbidity and mortality leading to significant healthcare expenditure in India. The country has experienced the outbreaks and epidemics of many infectious diseases. However, enormous successes have been obtained against the control of major epidemic diseases, such as malaria, plague, leprosy and cholera, in the past. The country's vast terrains of extreme geo-climatic differences and uneven population distribution present unique patterns of distribution of viral diseases. Dynamic interplays of biological, socio-cultural and ecological factors, together with novel aspects of human-animal interphase, pose additional challenges with respect to the emergence of infectious diseases. The important challenges faced in the control and prevention of emerging and re-emerging infectious diseases range from understanding the impact of factors that are necessary for the emergence, to development of strengthened surveillance systems that can mitigate human suffering and death. In this article, the major emerging and re-emerging viral infections of public health importance have been reviewed that have already been included in the Integrated Disease Surveillance Programme.Avian influenzaCCHFemergingIndiaNipah virusre-emergingrespiratory viral infectionsrotavirusviral diseasesJournal ArticleIndiaICMR-National Institute of Virology, Pune, IndiaMaximum Containment Laboratory, Pune, IndiaInfluenza Department, Pune, IndiaDivision of Epidemiology and Communicable Diseases, Indian Council of Medical Research, New Delhi, IndiaNational Center for Disease Control, New Delhi, India
