Zika Virus: Transmission, Detection, Control, and Prevention

Area of Science:

• Virology
• Epidemiology
• Public Health

Background:

• Zika virus (ZIKV), a mosquito-borne Flavivirus, has caused major outbreaks globally.
• ZIKV infection is often asymptomatic but linked to severe outcomes like microcephaly and Guillain-Barré Syndrome (GBS), particularly following its emergence in the Americas.
• Brazil reported significant increases in microcephaly and GBS cases in 2015, highlighting the public health threat.

Purpose of the Study:

• To review current evidence on ZIKV's association with prenatal microcephaly and GBS.
• To summarize ZIKV transmission dynamics, detection methods, and control strategies.
• To emphasize the need for efficient ZIKV detection techniques for improved surveillance and control.

Main Methods:

• Literature review of existing evidence on ZIKV.
• Analysis of ZIKV transmission dynamics, detection methods (molecular and serological), and control strategies.

Main Results:

• ZIKV infection is associated with increased rates of prenatal microcephaly and Guillain-Barré Syndrome.
• Current understanding of ZIKV transmission, detection, and control strategies is summarized.
• The review highlights the urgent need for sensitive, cost-effective ZIKV detection methods.

Conclusions:

• Understanding ZIKV transmission is key to developing targeted diagnostics and treatments.
• Efficient detection techniques are vital for effective ZIKV surveillance and control.
• Further research into ZIKV pathogenesis could inform disease management and control strategies.
