In-depth molecular analysis of a small cohort of human and Aedes mosquito (adults and larvae) samples from Kolkata revealed absence of Zika but high prevalence of dengue virus.

CONCLUSION: Both host and vector samples showed absence of ZIKV but high prevalence of DENV. The high rate of infection of larvae with DENV is suggestive of trans-ovarial transmission that could contribute to the surge of human infections during each post-monsoon season. It would be important to guard against false positives using the available Zika-reporting primer sets.
