futurity.org - Stanford University - May 5, 2017

New research shows how rising temperatures might influence mosquito behavior and disease risk around the world. The researchers also calibrated their model with field data on human infections of mosquito-borne diseases.

Scientists have known for some time that climate change has caused the extension of mosquito season beyond the summer months, but the ways in which climate change affects the risk of mosquito-borne diseases such as dengue, chikungunya, and Zika has remained somewhat mysterious . . .

 . . . The group found that mosquito traits favorable to spreading disease peaked when temperatures reached 29 degrees Celsius (84 degrees Fahrenheit), but were lower when temperatures were cooler or warmer.

cidrap.umn.edu - by Lisa Schnirring - April 21, 2017

Echocardiography evaluation of a group of Brazilian babies with Zika-related birth defects found three times the expected rate of congenital heart disease (CHD), but only one infant had symptoms and most had minor septal defects that weren't hemodynamically significant.

The study is the first time CHD has been assessed in infants with congenital Zika infections, and so far there haven't been any reports of autopsy findings suggesting a connection, but other flaviviruses such as dengue have been associated with myocarditis and pericarditis.

The number of babies born in Puerto Rico with microcephaly and other birth defects caused by the Zika virus appears to be unexpectedly low — so low that experts are beginning to question whether the actual count is being significantly underreported by authorities on the island.

Zika Found in Common Backyard Asian Tiger Mosquito

nbcnews.com - by Maggie Fox - April 14, 2017

A common backyard mosquito can be infected with the Zika virus and it may pass the virus along in its eggs, researchers reported Friday.

The findings add to worries that the Asian tiger mosquito, scientifically known as Aedes albopictus, could help spread the virus as mosquito season hits temperate regions of the world.

The study, published in the Journal of Medical Entomology, doesn't prove that tiger mosquitoes can spread Zika, which causes severe birth defects. But it adds to evidence that they might.
