A new study has found that the placenta is much more vulnerable to Zika infection in the first trimester of pregnancy and this explains why the congenital damage caused by the virus is more serious in the early stages of a child’s parental development. 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

We Know Zika Is A Big Problem In Puerto Rico. We Just Don’t Know How Big.

A JAMA paediatrics study published in October 2016 predicted that Puerto Rico would see 110 to 290 Zika-related microcephaly cases between mid-2016 and mid-2017. 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. Sources told Stat News Puerto Rico may be under reporting the Zika problem for fear of harming the tourism business

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.
