Zika link to microcephaly, neurological disorders show 'strong scientific consensus': WHO
32 babies with microcephaly in Colombia under investigation
In its previous weekly report, the United Nations agency said the mosquito-borne virus that is spreading across Latin America and the Caribbean was "highly likely" to be a cause.
"Based on observational, cohort and case-control studies, there is a strong scientific consensus that Zika virus is a cause of GBS (Guillain-Barré Syndrome), microcephaly and other neurological disorders," the WHO said in an update.
The WHO declared the Zika outbreak an international health emergency on Feb. 1, citing a "strongly suspected" relationship between Zika infection in pregnancy and microcephaly.
Microcephaly and other fetal malformations have also been reported in Colombia, where 56,477 suspected cases of Zika virus including 2,361 laboratory-confirmed have been reported.
Two babies from Cabo (Cape) Verde in Africa have also been reported as having microcephaly, it said.
