History of Zika
Zika virus was first discovered in 1947 and is named after the Zika Forest in Uganda. In 1952, the first human cases of Zika were detected and since then, outbreaks of Zika have been reported in tropical Africa, Southeast Asia, and the Pacific Islands. Zika outbreaks have probably occurred in many locations. Before 2007, at least 14 cases of Zika had been documented, although other cases were likely to have occurred and were not reported. Because the symptoms of Zika are similar to those of many other diseases, many cases may not have been recognized (CDC, 2016).
Diagnosis and Treatment
The Zika disease is caused by the Zika virus (ZIKV), an arbovirus of the falavivirus genus. It is transmitted by the bite of Aedes mosquitoes. After the mosquito bite, the disease symptoms usually appear after an incubation period of three to 12 days. The infected individual may present with fever and non-purulent conjunctivitis, headache, myalgia, arthralgia, asthenia, maculopapular rash, edema in lower limbs, and less frequently, retro-orbital pain, anorexia, vomiting, diarrhea or abdominal pain OR may be asymptomatic. Symptoms may last from 4-7 days and are self-limiting. Neurological and autoimmune complications are rare. There is no specific antiviral treatment or an effective vaccine for this disease. Symptomatic and supportive treatment for the acute phase is recommended and early diagnosis of atypical and severe forms is warranted.

Tracking and Notification
The CDC maintains enhanced surveillance of women who have possible or confirmed Zika infection during pregnancy and their babies for the first year of life.
Zika is a nationally notifiable disease. State and territorial health departments are encouraged to report laboratory-confirmed cases to CDC through ArboNET, the national surveillance system for arboviral diseases. Healthcare providers should report cases to their local, state or territorial health department according to the laws or regulations for reportable diseases in their jurisdiction (CDC, 2016).
Non-essential travel should be discouraged to areas where the incidence of the Zika virus is increasing or already prevalent. If travel is necessary to those areas, large-scale Public Service Announcements must be made with simple instructions (6th-grade reading level).
