New model for predicting Zika virus infection rates

Zika virus disease is easily transmitted. However, in the majority of people the disease is asymptomatic — symptoms appear in only one in four people, mostly as a mild fever. To find out why, a new study has been running.

Another neurological disorder linked to Zika virus

Vancouver - The World Health Organization (WHO) has already linked the Zika virus to one neurological disorder, Guillain-Barré syndrome in adults, and microcephaly in expectant mothers. But a new study has also linked the virus to a rare neurological disease.

Agrochemical companies circle their wagons over Zika virus

The seemingly increased number of cases of microcephaly in newborns in Brazil which coincided with a Zika virus outbreak has stunned the world. The Zika virus has been linked to cases of microcephaly, however there are some doctors who disagree.

Microcephaly — Is it Zika or maybe, agrochemicals?

Proving birth defects, and in particular, microcephaly in newborns is linked to the Zika virus is more difficult than many people realize. While cases of microcephaly have been found in seven countries, determining the cause is still a long way off.

Researchers studying the spread of infectious diseases say the Zika virus, possibly linked to birth defects, has the potential to spread across the Americas, including parts of the U.S.

'Strongest evidence yet' of birth defect linked to Zika virus

Studies on the mosquito-borne Zika virus have been ongoing in Brazil and in the U.S. since an upsurge in the number of babies born in Brazil with microcephaly in 2015. The CDC may have found the answer.

Op-Ed: Zika virus — 2700 cases in one year in Brazil, first U.S. cases

New York - The Zika virus is causing a rash of birth defects in Brazil. Birth defects include microcephaly, infants born with small heads. Zika is so bad doctors are advising women to avoid pregnancy.

Virus linked to newborn brain shrinkage rampages beyond Brazil

Until this year, Brazil had few cases of microcephaly, a debilitating and ultimately deadly disorder in which newborns are born with abnormally small brains. Then the country recorded almost 3,000 cases after reporting less than 200 cases in 2014.

As Zika virus spreads, Brazil reports 1,761 microcephaly cases
