MANGALURU: With a death suspected due to dengue in the district, the vector-borne diseases have arrived along with monsoons. But there seems to be a serious problem at hand with district health officials suspecting whether a different serotype of the virus had caused this death.In Dakshina Kannada, out of the four antigenic ally different serotypes of the virus only (Dengue virus ) DENV-2 and DENV-3 are found. District Health Officials say that in case DENV-1 or DENV-4 strains are responsible for the death, then matters become worse as it leads to complications like a life-threatening syndrome called Dengue Hemorrhagic Fever (DHF) or Dengue Shock Syndrome (DSS).
