Zika dangers

Zika linked to baby joint deformities

 

Brazilian researchers from Recife, the city at the centre of the Zika epidemic, describe seven suspect cases in the journal The BMJ.

The virus, which has been spreading across much of the Americas and has deterred some people from visiting the Olympic host country, is already known to cause a serious baby brain defect.

Mothers-to-be are urged to be vigilant.
