Brazilian scientists identify another type of Zika-transmitting mosquito
25 July 2016 Current Affairs: Brazilian scientists have identified Culex quinquefasciatus mosquito infected by the Zika virus as another type of Zika-transmitting mosquito.

 It was identified by researchers from the public Brazilian laboratory Fundacion Oswaldo Cruz (Fiocruz) in three out of 80 groups of mosquitoes analysed up until now. Up until now, transmission of the Zika virus was only known through the Aedes aegypti mosquito, the same vector that spreads Dengue and Chikungunya. 

The Culex quinquefasciatus mosquito is known as the domestic mosquito in Brazil. In Recife, where the majority of Zika cases of Brazil were registered, the population of this mosquito is estimated to be 20 times larger than that of the Aedes aegypti.

Zika virus  : Zika virus is vector borne disease transmitted primarily by mosquitoes. The virus is capable of causing serious birth defects i.e. neurological disorders and foetal deformation known as Microcephaly in which infants are born with abnormally smaller heads. 

Besides a possible link between the virus and Guillain-Barré syndrome (a condition in which the body’s immune system attacks part of the nervous system) is also suspected.
