Zika virus is a mosquito-borne flavivirus, which was initially isolated in Uganda in the year 1947.  Till the year 2006, only sporadic cases of the disease were reported.  However, in 2007, the first major outbreak of the disease was observed in Yap state and then in Southeast Asia and Western Pacific region.  Further, in May 2015, the first local transmission of Zika virus was reported in the American region and since then, cases have been isolated in almost 20 nations in the region. ,
As Zika virus infection in time and place has been associated with a simultaneous rise in the incidence of congenital malformations, microcephaly, and neurological complications such as Guillain-Barré syndrome (GBS), the disease has attracted a major attention from the international stakeholders. , In fact, there is a major threat of the disease to spread to other Latin American nations; thus, it is quite essential to monitor the spread of the disease in the region. ,
Acknowledging the recent cluster of microcephaly cases or other neurological disorders in Brazil, the Emergency Committee has declared that emerging Zika virus disease is a Public Health Emergency of International Concern.  Even though a strong causal association between Zika infection during the antenatal period and microcephaly is suspected, it is not yet confirmed. ,
In addition, it has been proposed to strengthen and standardize the surveillance mechanism for microcephaly and GBS, implement measures to prevent mosquito bites both among general population and high-risk groups, and disseminate standard case definitions and diagnostics in high-risk areas to contain the situation. , Further, measures such as facilitating development of rapid diagnostic tool to enable prompt implementation of control measures, improving risk communication to identify concerns of the people, ensuring community engagement and implementation of vector control measures, and offering counseling to pregnant women who have been exposed to Zika virus and follow-up them for their birth outcome. , Furthermore, there is an extensive need to invest in research activities to ensure the development of an appropriate vaccine or drug and to strengthen the health care delivery system so that it can respond to the high caseload of the neurological syndromes and congenital malformations. ,,
To conclude, Zika virus disease has emerged as a major public health concern and is expected to increase further in magnitude owing to the lack of immunity among the population in the affected regions. Thus, all the international stakeholders should work together to reduce the incidence of Zika virus-associated neurological diseases and congenital malformations.
