After a man in Italy was reported to have signs of Zika virus in his semen six months after exposure, scientists are questioning whether the virus is reproducing itself in the male genital tract.
A small number of babies infected with Zika virus in the womb have developed a rare birth defect involving muscle weakness and stiff joints, according to a new report of the cases.
As the globe warms, scientists warn about melting ice caps, rising sea levels and odd, extreme weather. But there’s another threat that may already be emerging: New (and old) diseases spreading in places once thought safe.
Melting permafrost may release “zombie pathogens” that have been frozen in ice for centuries, while warming temperatures will allow disease-spreading insects to roam far and wide. Threats now confined to the tropics will likely become problems at higher latitudes. Here are a few of the diseases that could thrive in a warming world.
Based on the paper-based sensors they made to detect viral-based pathogens like Ebola, a Wyss Institute at Harvard research team created a version that checks for Zika. This prototype method could reveal the presence of the disease in hours instead of the days or weeks it takes for blood tests, but it needs more refining before it’s accurate enough to be deployed.
