Panorama

Panorama travels to Brazil to investigate the mystery of the Zika virus. The city of Recife is at the centre of an epidemic of cases of microcephaly - babies born with abnormally small heads who suffer from brain and limb deformities. Reporter Jane Corbin meets the families living with this tragedy and hears from doctors and scientists working to solve the riddle of the Zika virus and trying to eradicate the mosquito which carries it.
