abstract
Crimean-Congo Haemorrhagic Fever (CCHF) is a vector borne zoonotic disease caused by Crimean Congo Haemorrhagic Fever Virus (CCHFV), a member of the genus Orthonairovirus in the family Nairoviridae and order Bunyavirales. CCHFV has been isolated globally from a variety of domesticated and wild mammals. Ixodid ticks of genus Hyalomma act both as reservoir and as vector for the CCHF virus. This study was carried out with the data acquired from the web portal of Integrated Disease Surveillance Programme (IDSP). Analysis of the data showed that a total of 34 outbreaks of CCHF had taken place in Gujarat, Rajasthan and Uttar Pradesh during 2010-19. Further the highest incidence rate of 2.01 per one million population was seen in the year 2013. It was found that the highest case fatality rate of 66.67 percent was reported in 2014. In addition to that the mortality rate was found to be in the range of 0-0.78 per one million population. Death to case ratio was found to be 45.33 per 100 people. About 62% of outbreaks took place in monsoon season (Jun-Sept). Laboratory Diagnosis of CCHF was carried out in BSL 3 or BSL 4 laboratories by RT PCR and ELISA/IFA. Treatment mainly consists of supportive therapy along an antiviral drug Ribavirin which has some effect on the virus. Active surveillance with timely diagnosis of the disease in addition with health education to high risk groups and vector control activities may aid to address the future threat of CCHF in India.
