TV report I saw today from Brazil.
The Zika Virus.
It's related to the more common dengue virus and no more lethal than dengue. Just proper care is enough to recover. Originally reported in Uganda in the 40s. The problem comes when people who's had dengue gets the Zika virus, the body gets fool into thinking it's dengue and instead of the body destroying the dengue that it knows, in some small cases the cells protect the Zika virus, hiding them.
At the start of the year in the north east region of Brazil there was an epidemic of Zika fever cases, and people thought nothing more of it. Now, women who got the virus when they were pregnant are giving birth to babies with microcephaly, which is smaller malformed/undeveloped brains. The last two months more than 300 cases of babies were born with this condition in the region. Scientist don't know how Zika got to the babies, they suspect hidden in cells travelling through the uterus.
They are doing a strong campaign of fumigation now but how many are already infected? Outbreak.
