Researchers in Brazil announced on Thursday, "the presence of the virus zika" in mosquitoes of the Culex family in the Eastern city of Recife. These findings were released with the words of caution, saying: "the findings will require additional studies to assess the potential involvement of a mosquito common in the spread of Zeke and his role in the epidemic."
The researchers collected 500 mosquitoes and found the virus in three groups of mosquitoes. Each pool contains from one to ten mosquitoes. The presence of the virus in these mosquitoes doesn't mean they can pass it.
Before that it was believed that the virus zika carry only mosquitoes of the Aedes Aegypti family. In the Metropolitan area of Recife ordinary mosquitoes 20 times more than mosquitoes aegypti, the study said.
The US centers for control and prevention of diseases and a senior press officer for the prevention Tom Skinner told CNN Thursday in response to the findings of the study, "the study will need to be replicated in order to have a better idea of the possible consequences. Analysis of scientific evidence to date clearly indicates the Aedes mosquito is the main vector involved in the outbreak Zeke ".
There are many different types of Culex mosquitoes. This study showed the virus in the mosquitoes Culex quinquefasciatus family. In a study published in the US earlier this week in the journal Emerging infectious diseases, refers to another type of Culex mosquito, which is not able to transmit zika virus in the laboratory.
The virus is spreading throughout North and South America since last year. The world health organization declared a state of emergency in public health of international importance. Since then, researchers have found that the virus can cause devastating birth defect called microcephaly, in infants born from mothers who were infected during pregnancy.
