Diagnostic tests for human rabies.

Area of Science:

• Medical Diagnostics
• Infectious Diseases
• Public Health

Background:

• Reliable data on human rabies deaths is lacking, leading to underestimation and neglect of the disease.
• Clinical diagnosis of human rabies is difficult and lacks specificity.
• Traditional post-mortem diagnosis using immunofluorescence is invasive.

Purpose of the Study:

• To highlight the need for improved human rabies diagnostic tests.
• To discuss advancements in intra-vitam diagnosis of human rabies.
• To address challenges in implementing these diagnostic techniques globally.

Main Methods:

• Review of historical and modern diagnostic techniques for human rabies.
• Evaluation of minimally invasive (saliva, skin biopsies) and non-invasive sampling methods.
• Discussion of molecular techniques and their validation.

Main Results:

• Intra-vitam diagnosis of human rabies is now possible with validated, robust techniques.
• New methods allow for diagnosis using less-invasive samples, suitable for resource-limited settings.
• Progress has been made in molecular techniques and sampling.

Conclusions:

• Establishing reliable diagnostic tests is a priority for accurate rabies assessment.
• Accessible, validated techniques are essential for confirming suspected human rabies cases, especially in low-income countries.
• Development of rapid, low-cost methods for rural and remote areas is necessary.
