Polymerase Chain Reaction-Based Detection Method Is Suitable for Dengue Infection During Epidemics

Area of Science:

• Virology
• Infectious Diseases
• Molecular Diagnostics

Background:

• Dengue fever is a significant global infectious disease with no available vaccine.
• Current treatments for dengue are limited, and severe symptoms can develop.
• Accurate early diagnosis and serotype identification are essential for effective management.

Purpose of the Study:

• To evaluate immunological and nucleic acid-based methods for dengue virus detection.
• To determine the sensitivity and specificity of different diagnostic techniques.
• To assess the utility of molecular methods for dengue serotype identification.

Main Methods:

• Comparison of immunological assays (antibody detection) with nucleic acid-based molecular methods.
• Utilized polymerase chain reaction (PCR) for dengue virus detection.
• Analyzed nucleic acid sequences to identify dengue serotypes/genotypes.

Main Results:

• Polymerase chain reaction (PCR) demonstrated higher sensitivity compared to antibody detection methods.
• Nucleic acid analysis proved effective in identifying circulating dengue serotypes/genotypes.
• The study confirmed PCR as a suitable method for rapid dengue virus detection.

Conclusions:

• Polymerase chain reaction (PCR) is recommended for rapid and sensitive dengue virus diagnosis.
• Nucleic acid analysis aids in understanding regional dengue virus epidemiology.
• Improved diagnostic tools are vital for managing dengue fever effectively.
