All 6 pregnant women contracted the Zika virus while traveling to countries south of the border, including Mexico, Guatemala and El Salvador.
According to a CDC report, 8% of offspring of pregnant women who tested positive for Zika in the 1st trimester, 5% in the 2nd trimester and 4% in the 3rd trimester had birth defects linked to the virus.
Researchers found that Aedes aegypti might transmit Zika, chikungunya and dengue viruses with one bite – called coinfection.
The alert network will allow people to share their observations and help scientists to monitor emerging trends.
Zika is carried by mosquitoes both in Brownsville and across the border in Mexico. With so many people going back and forth every day, it’s hard to know exactly where they picked Zika up.
Researchers have identified antibody Z004, which was effective at neutralizing both Zika and dengue 1 and shows promise as a new potential strategy for developing a vaccine.
Recent studies of infected rhesus monkeys show retention of the Zika virus in the gut lining and lymph nodes.
The Zika outbreak may have prompted a drop in the number of live births in Rio de Janeiro. Researchers believe that very early miscarriages and pregnancy avoidance may be to blame.
Professionals warn that a Zika outbreak in the Rio Grande Valley at the southernmost tip on the Texas border with Mexico is just a matter of time. With 1.3M people live in poverty – many without AC and window screens – this area is conducive to an outbreak.
20,000 male Aedes aegypti mosquitoes infected with a naturally occurring bacteria called Wolbachia were recently released in the Florida Keys. When the infected males mate with female mosquitoes, the eggs she produces won’t hatch. Florida’s mosquito-control experts are hoping for a decline in Aedes aegypti population and the number of locally-transmitted Zika cases.
