Culex must modify combat zika control actions of Aedes aegypti and muri?oca are different

The larvicide, for example, is adopted to combat Aedes has no effect against muri?oca international, national, state and municipal managers await confirmation of the presence of zika in gnats (Culex) Wild collected in RMR and are targets of a survey of Fiocruz Pernambuco.Preliminary results of the analysis identified the insect naturally contaminated in the streets, as the Folha de Pernambuco anticipated, rekindled the possibility of this vector also have contributed to the zika epidemic, especially in vulnerable areas without basic sanitation, such as Recife, which has only 32% sanitized. In the state are about 20%. On Monday (20), at a seminar organized by the State Secretary of Health (SES), experts gathered to discuss the surveillance measures and responses to arboviruses. For all, the expected confirmation of Culex represent a change in coping strategies. "The vector control actions are different complements. What we do to control the Aedes aegypti as the larvicide, for example, is not for the Culex. They are other actions. Basic sanitation is essential. But to rethink this control only from Fiocruz information ", said the executive secretary of Health Surveillance of SES, Luciana Albuquerque. Recife, which has waged a battle against muri?oca in past decades in the fight against filariasis, should start another journey. This time to contain the possible transmission of zika. "If confirmed, we will initiate appropriate control actions. We sat with some organs like Compesa and Department of Infrastructure, depending on Aedes, to discuss improvements in environmental and health conditions. Now, this conversation should be narrowed, "said the executive secretary of Health Surveillance of Recife, Cristiane Penaforte. Another challenge ahead is to know the infestation of gnats in cities that do not have a watch as present as the Aedes. "We do not do this scouting infestation there is no national policy for this. I believe that once disclosed the possibility of transmission, we have to do, "said Earthwatch manager Recife, Jurandir Almeida. The director of the Department of Communicable Disease MS, Eduardo Hage, preferred to be measured on the condition of muri?oca as possible vector zika. "If confirmed, will be a step in the matter of elucidating other potential transmitters of these viral diseases," he said. Hage added that often are detected virus other diseases mosquitoes, but they are not good transmitters. They do not have enough vectorial capacity. "Identifying the virus exists within the insect and can reproduce here is an important step. But there are other steps to be overcome so that will have epidemiological importance.

RIO DE JANEIRO (Reuters) - Brazilian researchers on Thursday said they found signs of the Zika virus in a common mosquito that is a separate species from the insect known to be the primary means of transmission.
They warned, however, that further tests are needed to determine whether the species, known as Culex quinquefasciatus, is in fact responsible for transmitting the virus to humans and, if so, to what extent.
The scientists, from a leading Brazilian research institute known as the Oswaldo Cruz Foundation, discovered the Zika traces in Culex mosquitoes captured in and around the northeastern Brazilian city of Recife, capital of the state that was hit hardest by the Zika outbreak since last year.
In March, the same researchers said they had successfully transmitted the Zika virus to Culex mosquitoes in the lab, but were not yet sure at the time whether the species could carry the virus naturally.... http://www.huffingtonpost.com/entry...r=WorldPost&section=us_world&utm_hp_ref=world
 
Zika found in common house mosquito in Brazil: Researchers
Updated: Jul 22, 2016 13:43 IST
New York, July 22 (ANI): Researchers in Brazil have announced the "presence of the Zika virus" in Culex mosquitoes, the common house mosquito in the eastern city of Recife.
The statement was released yesterday with word of caution, saying "the obtained data will require additional studies in order to assess the potential participation of Culex in the spread of Zika and its role in the epidemic," reports CNN.
The researchers found the virus in three pools of 500 mosquitoes.
Zika was thought to solely by carried by the Aedes aegypti mosquito, before this study was completed by the Oswaldo Cruz Foundation (Fiocruz).... http://www.aninews.in/newsdetail-NE...mon-house-mosquito-in-brazil-researchers.html
