Brazil is trying to fight the rapid spread of the mosquito-borne Zika virus, as the number of new-borns with brain defects soars.  

Zika is a mosquito-borne virus linked to an alarming surge in infants borne with serious brain deformation. 

Some four-thousand suspected cases of microencephaly have been reported in Brazil since October, compared to 150 cases in all of 2014.

In addition to fumigating, health officials have launched a campaign to educate people on how to prevent mosquito breeding in their homes.

Zika is transmitted by the same mosquito that transmits diseases like dengue and chikangunya.

There is no vaccine or treatment for it.

Brazil is trying to get the epidemic under control before the country hosts the Olympic Games in Rio de Janeiro in August.
