Zika Virus Disease.

Area of Science:

• Virology
• Epidemiology
• Public Health

Background:

• Zika virus, a Flaviviridae family arbovirus, was first isolated in Uganda in 1947.
• Initially causing mild infections, Zika outbreaks shifted significantly in 2007, with widespread human cases reported.
• Recent outbreaks have shown severe clinical signs, including microcephaly and Guillain-Barre syndrome.

Purpose of the Study:

• To review the epidemiology and transmission of Zika virus.
• To highlight diagnostic challenges and clinical manifestations.
• To emphasize the need for global efforts in Zika virus prevention and control.

Main Methods:

• Literature review of Zika virus epidemiology, transmission, and clinical presentation.
• Analysis of diagnostic methods and challenges.
• Discussion of factors influencing Zika virus spread and control.

Main Results:

• Zika virus transmission occurs via mosquitoes (primarily Aedes aegypti), and also through mother-to-fetus, sexual contact, blood transfusions, and other routes.
• Differential diagnosis is crucial due to overlapping symptoms with other arboviruses like Dengue and West Nile virus.
• Reverse transcription polymerase chain reaction (RT-PCR) is the primary diagnostic test, though established tests are limited.

Conclusions:

• The rapid spread, changing severity, and multiple transmission routes of Zika virus necessitate coordinated global control strategies.
• Challenges include limited research, co-infections, vector involvement, population movement, and lack of vaccines.
• Collective efforts are crucial for effective Zika virus disease prevention and management.
