The National Institute of Health today said that of the 33 cases of microcephaly reported so far this year, two have been confirmed to have been caused by the mosquito-borne virus. Another 15 cases remain under analysis while 16 cases have been ruled out for any relation to the virus.
The government agency said that one case was in Norte de Santander department near the border with Venezuela and the other in the lowland areas near the capital, Bogota. No other details were provided out of respect for the families' privacy.
The announcement comes a day after the Centers for Disease Control confirmed that there's no doubt Zika is a cause of the birth defects.
Colombian authorities have been on the lookout for a rise in microcephaly ever since the epidemic hit Brazil. But authorities say the 33 cases of microcephaly reported in the country so far in 2016 don't represent a statistical aberration from previous years.
