Zika Virus: What Do Emergency Physicians Need to Know?

Area of Science:

• Infectious Diseases
• Virology
• Public Health

Background:

• Zika virus (ZIKV) has gained significant public attention due to its severe complications.
• Global travel facilitates the rapid spread of ZIKV, impacting regions including the U.S.

Purpose of the Study:

• To offer physicians a comprehensive clinical review of Zika virus.
• Key aspects covered include epidemiology, pathogenesis, diagnosis, management, and differential diagnoses.

Main Methods:

• Literature review of current Zika virus research.
• Synthesis of information on transmission, clinical presentation, and diagnostic methods.

Main Results:

• ZIKV is transmitted by Aedes mosquitoes and through sexual contact.
• Clinical presentation includes low-grade fever, rash, conjunctivitis, and arthralgias; only 20% of infected individuals show symptoms.
• Major complications include microcephaly in infants and Guillain-Barre Syndrome.

Conclusions:

• Zika virus shares similarities with Chikungunya and Dengue Fever, necessitating careful differential diagnosis.
• Effective management relies on symptom control, as no specific antiviral treatment is currently available.
• Physicians must consider travel history and rule out similar arboviral diseases.
