ZIKA virus is found in Brazil. Symptoms shown by people with ZIKA virus are mild fever, skin rash and conjunctivitis for about 2-7 days, but it is different story for pregnant women.
The World Health Organization said the disease affects the growth of the foetus, leading to microcephaly or stunted brain growth.
WHO is predicting that ZIKA will spread to all Americas except Canada and Chile.
Concerns are growing that it may be a worldwide issue with the 2016 summer Olympic Games coming up in Rio de Janeiro, Brazil.
