In 2016, the US Centers for Disease Control and Prevention confirmed that the Zika virus caused birth defects in babies born to women who had been infected while pregnant. This was the first mosquito-borne disease known to cause birth defects . . . 

 . . . Now, a study suggests that two viruses that are related to Zika can cause similar birth defects.

West Nile and Powassan viruses caused fetal death in infected pregnant mice, the researchers say.

Researchers identified three new mosquito carriers of Zika virus in Mexico and say all three are potential vectors of the disease.

Writing in Scientific Reports, the researchers reported isolating Zika virus from the salivary glands of wild-caught female Culex coronator, C.tarsalis and Aedes vexans mosquitoes, as well as other previously reported vectors, including A. aegypti, the primary driver of the recent Zika virus epidemic in the Americas. They also isolated Zika from different body parts of wild-caught female C. quinquefasciatus mosquitoes and whole males from the A.aegypti and C. quinquefasciatus species.

“Our findings strongly suggest that all the species reported herein are potential vectors for [Zika virus],” they wrote.

Climate change is altering the environment in ways that increase the potential for viruses like Zika.

 . . . Climate change is turning abnormal weather into a common occurrence: Last year was the warmest year on record, the third in a row, and there were more heat waves, freezes and storms in the United States that caused $1 billion or more in damage just in 2016 than in the years 1980 to 1984 combined. Anything that improves conditions for mosquitoes tips the scales for the diseases they carry as well: the West Nile virus that flattened Dallas, the dengue that returned to Florida in 2009 after 63 years and the newest arrival, Zika, which gained a toehold in the United States last year and is expected to surge this summer . . .

Brazil's microcephaly epidemic continues to pose a mystery -- if Zika is the culprit, why are there no similar epidemics in other countries also hit hard by the virus? In Brazil, the microcephaly rate soared with more than 1,500 confirmed cases. But in Colombia, a recent study of nearly 12,000 pregnant women infected with Zika found zero microcephaly cases. If Zika is to blame for microcephaly, where are the missing cases?
