In February 2016, the World Health Organization (WHO) declared the Zika virus outbreak a global public health emergency. The epidemic is raging in over 30 countries in the Americas, Pacific Islands, and several other regions around the world. The Zika virus belongs to the Flaviviridae family, which also includes the yellow fever, dengue, chikungunya, Japanese encephalitis, and West Nile viruses. It is transmitted by Aedes mosquitoes, especially Aedes aegypti and Aedes albopictus. Other mosquito species such as Anopheles and Culex are also considered potential Zika virus vectors. Symptoms are usually mild to moderate, including fever, bilateral non-purulent conjunctivitis, rash, and arthralgia.
