ZIKA virus strain

WHO says three babies have
been born brain damaged
with microcephaly.
Until the virus was
sequenced by scientists in
Senegal, it was not certain if
the outbreak in Cape Verde
was caused by the African
or Asian type, which has
hit Brazil and other Latin
American countries.
Tests show that this is the
Asian strain – the same as
the one blamed for birth
