Zika virus: 2.2 billion people in “at risk” areas



More than two billion people live in parts of the world where the Zika virus can spread, detailed maps published in the journal eLife show.

The Zika virus, which is spread by Aedes aegypti mosquitoes, triggered a global health emergency this year.

Last week the US Centers for Disease Control and Prevention confirmed that the virus causes severe birth defects.

The latest research showed mapping Zika was more complex than simply defining where the mosquito can survive.

One of the researchers, Dr Oliver Brady from the University of Oxford, told the BBC: “These are the first maps to come out that really use the data we have for Zika – earlier maps were based on Zika being like dengue or chikungunya.

“We are the first to add the very precise geographic and environmental conditions data we have on Zika.”

By learning where Zika could thrive the researchers could then predict where else may be affected. The researchers confirmed that large areas of South America, the focus of the current outbreak, are susceptible.

In total, 2.2 billion people live in areas defined as being “at risk”.

The infection is suspected of leading to thousands of babies being born with underdeveloped brains.

The at-risk zones in South America include long stretches of coastline as well as cities along the Amazon river and its tributaries snaking through the continent.

And in the US, Florida and Texas could sustain the infection when temperatures rise in summer.

Dr Brady added: “Mosquitoes are just one condition needed for Zika to spread but there’s a whole range of other ones.

“It needs to be warm enough for Zika to replicate inside the mosquito and for there to be a large enough [human] population to transmit it.”

Both Africa and Asia have large areas that could be susceptible to the virus, the researchers said.


really ramping up the hype now..reminds me of swine flu..

wait for the announcement that 1/4 of the world should get a jab to “save” them from zika..

  1. “There needs to be heat so that the virus can replicate inside the mosquito”
    I could be wrong but a virus needing heat to replicate ?
    The mosquitoes need heat to survive but the virus inside them – ah global warming again .

    An almost unknown and mild virus becomes the major threat to the world ?
    And after gates fiddles about with GM mosquitoes ?

  2. Dr Oliver Brady from the University of Oxford…what an incompetent liar.

    Pushing the outright lie that Zika is a threat. Can Brady show the large population of small-head syndrome in Africa where apparantly Zika was discovered?

    Or the converse, the US has 25,000+ cases of microcephaly every year. Why has the fraudulent CDC not declare Zika an emergency in the US prior to 2016?
    Zika a threat = Bullshit! = Vaccine profits = research grants!

    • The case for a vaccination being built up on weak evidence of one or two alleged victims.

      Why not concentrate on the hundreds of millions of malaria , dengue mal nutrition etc deaths . Obvious a vaccine is a cash cow for almost no effort.
