Introduction: Dengue and chikungunya are Aedes mosquito-borne viral diseases of major public health concern in India. Recently, there is a gradual rise in number of dengue and chikungunya positive cases in various states of Northern India and a similar emergence and increase of dengue positive cases has been observed in Jammu since 2011. Among the mosquito-borne diseases dengue has become a regular seasonal disease while chikungunya has recently emerged in 2016 and Zika the third aedes borne viral infection is needed to be under surveillance under national guidelines.

Aim: To report the emergence of chikungunya and analyse the status and pattern of dengue over a period of one year along with serosurveillance of Zika which was done under Central Government guidelines.

Materials and Methods: A total of eight hundred eight (808) samples from patients suspected of dengue infection over a period of one year from January 2016 to December 2016 from all the districts of Jammu Province, were tested serologically at our tertiary care centre for dengue NS1 antigen and IgM anti - dengue antibodies. Besides three clinical suspects of chikungunya, 167 dengue (7 positive and 160 negative) sera were tested by National Institute of Virology (NIV) CHIK IgM Capture ELISA, as there is an overlap of clinical symptoms. For Zika testing, the stored negative samples of dengue and Chikungunya (215) were sent to NIV Pune.

Results: Recurring dengue infection with periodic upsurge since last few years and emergence of chikungunya was reported in Jammu region. Of the 808 sera tested for dengue and 170 tested for chikungunya, 17.82% and 18.2% were positive respectively. The results for Zika testing were negative. The association of dengue on the basis of sex was found to be highly significant (p=0.009276).

Conclusion: In the absence of specific treatment and vaccine for dengue and chikungunya fever, early diagnosis is important in the management of these infections. This also demands continuous seroepidemiological surveillance of the locally prevalent and emerging arthropod borne infections for timely formulation and implementation of effective arboviral control programme.
