Researchers have found that certain viruses may have a trick up their sleeve that can make humans more attractive to mosquitoes. The study also revealed a possible remedy.
Subtle developmental differences in children whose brains seemed normal at birth underscore the need to follow children long term — a lesson that may be key for babies exposed to COVID-19.
In 2015, the mosquito-borne virus Zika exploded in South America. Health experts predicted it would erupt in Africa. But a major outbreak never happened. Now scientists think they understand why.
The largest study to follow women infected with Zika while they were pregnant finds about 6 percent of children had problems at birth, but 14 percent had complications by their first birthday.
The first known human case of the virus was identified in a Florida teen after a year of tests. Known symptoms include fever and a severe rash, but it's unclear if it causes brain inflammation.
A study looks at the rate of miscarriage — and of babies born with the birth defect — among a group of pregnant women in Brazil. Researchers were surprised by what they found.
