Epidemiological Updates of Zika Transmission and Emphasizing the Critical Role of Public Health Interventions
Abstract:
Since the start of Zika epidemic this
year, till date there are more than 45 countries with active Zika virus transmission.
Considering its spread at an alarming rate with large
clusters of microcephaly and neurological complications, the Emergency Committee
of the World Health Organization (WHO) under the International Health Regulations
(IHR) announced that Zika constitutes Public Health Emergency of International Concern
(PHEIC) on February 1, 2016. Countries in Central America and South America
show a decreasing trend of cases where as there is an increasing number of cases
in USA and some Caribbean states. Recently after careful review of the existing
evidence the scientists at CDC concluded that Zika virus causes Microcephaly a condition
in which the size of baby’s brain and head is smaller than the normally expected.
For planning more effective disease control and prevention activities for Zika fever
there is great need for a functional and intensified Public Health Surveillance
system Preparedness for the prevention and control of Zika virus infection. Risk communications
should be enhanced in countries with Zika virus transmission to address population
concerns, enhance community engagement, improve reporting, and ensure application
of vector control and personal protective measures. Vector control measures and
appropriate personal protective measures should be aggressively promoted and implemented
to reduce the risk of exposure to Zika virus. Attention should be given to women
of childbearing age and particularly pregnant women so that they have the necessary
information and materials to reduce risk of exposure
