The CDC guides men from South Florida, including Broward and Palm Beach counties, to refrain from donating sperm because they are at greater risk of spreading Zika.
So far, 29 travel-related cases of Zika have been registered in Utah, 11 of these cases have been pregnant women.
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.
Researchers will soon begin the 2nd phase of human clinical trials for a DNA vaccine candidate for Zika. 3½ months from design to injection is warp speed, but it’s easy to move very quickly with DNA vaccines.
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.
Zika-related birth defects were seen in about 3 out of every 1,000 births during 2013-2014 compared to 60 out of every 1,000 completed pregnancies where the mother tested positive for a Zika infection.
Collier County reported its 1st new Zika case of 2017 and Miami-Dade reported 3 new local transmissions.
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.
Researchers found that the Zika virus appears to create disorganization in the cellular layers of the placenta that keep toxins, bacteria and viruses from crossing, potentially allowing the virus to penetrate the fetus.
The first vaccine to be approved for clinical trials by the U.S. is now undergoing human trials in the U.S., Canada and Puerto Rico. The vaccine has the potential to also protect the male reproductive organ, preserving fertility and restricting testicular damage.
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.
The medians and 95th percentiles for the time until the loss of detectable Zika virus RNA detection were 14 days and 54 days, respectively, whereas 90% of patients infected with dengue viruses clear RNA within 10 days after the onset of symptoms.
