Why it’s so important to know your own risks
It’s been a little over a year since the first of the US states launched its state-led response to Zika virus outbreaks, and the US is not alone.
Many countries have been trying to curb the spread of the virus, which is transmitted through the mosquito-borne Aedes aegypti mosquito.
But there are still a few lingering questions about how well this strategy will work.
In the US, there is little doubt that the new rules are working, as some states have seen the number of cases drop by more than half.
But while the number and spread of cases have fallen in the US and elsewhere, the virus remains active in a number of other countries, including Brazil and Russia, and its spread remains a concern in the Middle East and the South-East.
There is still the issue of the link between the two countries’ mosquito-breeding regimes.
And despite the recent suspension of the new Zika-control measures in some states, the World Health Organisation still warns that there is a risk of another virus-transmission pandemic, as the virus may be able to cross the border and travel to more developed countries.
