Experts ask why Zika isn’t causing birth defects in Colombia

To date Colombia has reported more than 20,000 cases of the virus.

No country outside Brazil has confirmed more Zika cases than Colombia — including more than 2,100 pregnant women who have had the virus. But so far health officials have not found a single case of the birth defect known as microcephaly among those expectant mothers.

Brazilian authorities have received more than 4,000 reports of suspected microcephaly cases linked to Zika. But in the first 762 cases they have examined, only 270 had microcephaly that appeared to be caused by Zika or another infection. (Microcephaly can also be caused by genetic disorders and such things as maternal alcohol abuse).

Bemærk at af de undersøgte tilfælde af mikroencefali i Brasilien, ser kun 1/3 ud til at være forårsaget af Zikavirus eller anden infektion.

Hvor længe er smitteperioden?
Er det kun farligt for gravide at blive stukket mens de er gravide eller vil man hvis stukket og efterfølgende bliver gravid også ha en teoretisk øget chance for microcephali?
Opbygger man imunitet eller er der som ved e.g. dengue risiko for komplikationer ved gentagne stik?
