Researchers also found that the Zika strain in Africa is more virulent than the Asian strain. The African strain multiplies faster than the Asian strain, destroying placental cells and compromising gestation

But at the last count there were only 16 babies born with microcephaly, a staggeringly low number given the island has had 3,200 cases confirmed zika cases in pregnant women since the beginning of the outbreak.

STAT: Personal conflict may be at the root of Puerto Rico's Zika reporting problem

The media obtained a document indicating that Puerto Rico may be intentionally under reporting Zika cases. The issue stems from a personal dispute between Miguel Valencia MD, the Puerto Rican official in charge of the territory’s tracking programme, and the CDC Director of the Vector-Borne Diseases Lyle Petersen MD, according to the report. Dr Valencia has instructed staff to use his criteria, which is narrower than that of the CDC, in identifying and recording Zika-related birth defects

Clues to Zika Damage Might Lie in Cases of Twins

While identical twins often share a fate, fraternal twins typically don’t, a divergence that offers clues to researchers. With one sibling affected by microcephaly because his mother was bitten by a Zika infested mosquito during pregnancy and the other apparently spared, doctors are hoping that these nine sets of twins identified in Brazil’s Zika crisis may shed some light on how the virus works generally and why it inflicts ruthless damage on some babies and not others.
