2. Zika virus
What it is: The Zika virus is transmitted by the Aedes mosquito. It was first identified in Uganda in 1947 in monkeys. It was later identified in humans in 1952. The Zika virus is known to cause serious complications in unborn babies when contracted by pregnant women – these include congenital brain abnormalities.
How is it contracted? It is transmitted by mosquitos. While it can’t be transmitted from person to person in most cases, it is believed that the Zika virus can live in semen and be transmitted through s3xual intercourse. It can also be passed on from a mother to her unborn child.
Signs and symptoms: The incubation period of the Zika virus is still unclear according to the WHO, but is estimated to be a few days. The symptoms are mild and last for two to seven days – including fever, a rash, headache and joint pain.
When and where: The most recent outbreak of the Zika virus was reported in May 2017 in India. Zika was also reported to be present in some parts of North America, Brazil, South America and parts of the Caribbean.
