Brazil has been hardest hit by the Zika virus, which is thought to have arrived there in 2014 during the World Cup soccer tournament.
Since then, the number of cases of illness has exploded – with estimates of at least 1.5 million people infected in Brazil alone. The World Health Organization predicts it could spread to three to four million people across the Americas in the next 12 months. The virus has been suspected of causing an increase in cases of microcephaly – children born with unusually small heads, often with brain damage.
