Dengue Epidemiology-Visakhapatnam (GVMC Peri-Urban)

M. Satyanarayana Raju, Yenni Mani

Abstract :

In the recent past significant number of dengue cases are reported from peri–urban areas. Gajuwaka, Anakapalli, Bhimili Municipalities and 13 Grama Panchayat are considered as peri–urban (GVMC –Rural). As per the classification of dengue basing on severity in South –East Asia region, India falls under category A ⁽¹⁾ and dengue is Major public health problem. Though dengue is notifiable ⁽²⁾, the true incidence is not reported by GVMC like, many other local bodies because of the fear from press and local politicians. Most of the dengue fevers are identified as un–differentiated fevers⁽³⁾ and there is no further follow up. Some of such fevers may land in dengue hemorrhagic fever /dengue shock syndrome⁽⁴⁾ which are life threatening. The disease in peri–urban ⁽⁵⁾ areas of Visakhapatnam has shown seasonal pattern. Aedes aegypti was found in the houses. Visakhapatnam being costal area climate i.e.^{( 6)} annual rain fall (ranging from 1013mm to 1439 mm, 2012 to 2017, source : Cyclone warning center, VSP, Meteorological dept ,govt of India) temperature  (16 ⁰ c – 30 ⁰ c) and a relative humidity (60 to 80 percent) are congenial for eeding of Aedes mosquitoes and transmission of virus. Unlike Visakhapatnam urban, there is no Urban Malaria Scheme⁽⁷⁾ operating in peri–urban areas except active, passive surveillance, radical treatment for positive cases and Indore residual spray⁽⁸⁾ (not accepted by residents). In view of the present situation and further rapid urbanization, lifestyle changes and deficient water management including improper water storage, future epidemics are expected in peri–urban areas also. It is highly essential to prepare advance action plan particularly identifying the high risk areas for implementation of⁽⁹⁾ Integrated Vector Management. Further it is necessary to extend the UMS to peri–urban areas also on par with GVMC Urban.
