Zika Virus: Medical Countermeasure Development Challenges

Area of Science:

• Infectious Diseases
• Epidemiology
• Virology
• Immunology
• Public Health

Background:

• Zika virus infection is linked to high rates of microcephaly and Guillain-Barré syndrome.
• No licensed medical countermeasures (vaccines, therapies, or preventive drugs) are currently available for Zika virus.
• The Pan American Health Organization anticipates widespread transmission in the Americas.

Purpose of the Study:

• To review the current Zika virus outbreak status.
• To explore medical countermeasure options for Zika virus.
• To analyze how epidemiology, vectors, neuropathology, virology, and immunology inform countermeasure development.

Main Methods:

• Literature review, patent analysis, and review of official communications.
• Analysis of online physician surveys from the US, Mexico, and Argentina.
• Computational epitope analysis, infectious disease outbreak modeling, and field observations in Brazil.

Main Results:

• The review synthesizes information on the Zika virus outbreak and potential medical countermeasures.
• Epidemiological data, vector characteristics, neuropathology, virology, and immunology are considered.
• Physician survey responses provide insights into clinical perspectives.

Conclusions:

• Understanding the multifaceted aspects of Zika virus is crucial for effective medical countermeasure development.
• Integrated strategies leveraging epidemiological, entomological, and immunological data are needed.
• Urgent development and deployment of medical countermeasures are essential to combat the Zika threat.
