Palpitation followed by shortness of breath and fatigue were symptoms of heart problems in 8 of 9 patients in Venezuela within 2 weeks of having Zika-type symptoms.
Researchers found that during the first trimester of gestation the placenta produces genes encoding proteins which the Zika virus finds a favorable biological environment for infection.
Caribbean travelers – the vast majority by cruise ship – were the primary means of introducing the 2016 Zika outbreak in South Florida. Researchers also confirmed that decreases in the Aedes aegypti population from pesticide spraying corresponded with a subsequent drop in new reported Zika cases.
5% of travelers who visited travel medicine clinics in British Columbia through Quebec from Oct. 2015 to Sept. 2016 sick with the Zika had a neurological condition including Guillain Barre.
Research shows that the Asian lineage Zika virus halted the proliferation of brain stem cells and hindered their ability to develop into brain nerve cells. The Zika infection was mainly found in glial cells, which provide support and insulation for the brain.
Babies diagnosed with CZS continue to struggle in NE Brazil. As a result, many families held off pregnancy. The birthrate in Pernambuco, which includes Recife, fell 7% last year as 70% of Recife’s inhabitants contracted Zika in 2015 and 2016. The birthrate dropped 45% at private clinics.
A new Zika candidate vaccine uses tiny modified strands of RNA that hold the genetic codes for making viral proteins so that they can easily enter cells, inducing a level of virus neutralization ~25 times greater after a single dose than standard vaccines.
A new MIA detects Zika in blood in less than 4 hours and for a longer period of time after infection and reduces the instances of false positives. A quicker diagnosis helps authorities locate new Zika hot spots and control mosquito populations sooner.
New findings show that the Zika virus (ZIKV) effects more than 500 genes/proteins present in developing brain cells and explain some of the consequences seen on brain formation and function.
Puerto Rico is pushing for more federal funds to fight Zika and provide incentives to doctors who don’t normally accept medicaid patients. The CDC estimates that 10,300 pregnant women could be infected and that 100-270 babies could be born with microcephaly.
