That forecast could represent a fivefold spike inside the wide variety of Colombian microcephaly cases seen on average every year.

"we are doubting that discern. we are studying what's taking place in Brazil, however between while we released the estimate and now we have not found a single case of microcephaly," Gaviria stated. "The extrapolation of Brazil's figures to Colombia, which is how we were given the projection, now does not seem reasonable."

much stays unknown approximately Zika, including whether or not the virus certainly causes microcephaly.

a pandemic of the virus became first detected in Brazil early final yr and is now spreading rapidly thru the Americas.

Brazil has thus far been the only u . s . a . to file a spike in instances of the start illness, with greater than 4,four hundred reported instances, of which extra than 500 have been confirmed as microcephaly.

however it may take numerous extra weeks, or months, as signs of microcephaly may simplest be detected very late in pregnancy, professionals say.

"If Zika is in reality the motive of microcephaly, we need to expect to peer microcephaly instances in Colombia in June," Espinal said.

Colombia in the beyond has reported a especially better prevalence of microcephaly, relative to its populace, than Brazil, suggesting there may additionally had been beneath-reporting within the larger united states of america, Gaviria stated.

The Zika virus has additionally been connected to Guillain-Barre syndrome, that may motive paralysis. The ministry expects round 60 cases of the syndrome month-to-month, an boom of fifty percentage, Gaviria stated.

3 deaths from Guillain-Barre were related to Zika in Colombia. One affected person tested positive for the virus, while the opposite  were recognized by using medical doctors but did no longer have their cases confirmed by using a lab, he stated.
