Molecular and Immunological Diagnostic Techniques of Medical Viruses

الملخص EN

Viral infections are causing serious problems in human population worldwide.

The recent outbreak of coronavirus disease 2019 caused by SARS-CoV-2 is a perfect example how viral infection could pose a great threat to global public health and economic sectors.

Therefore, the first step in combating viral pathogens is to get a timely and accurate diagnosis.

Early and accurate detection of the viral presence in patient sample is crucial for appropriate treatment, control, and prevention of epidemics.

Here, we summarize some of the molecular and immunological diagnostic approaches available for the detection of viral infections of humans.

Molecular diagnostic techniques provide rapid viral detection in patient sample.

They are also relatively inexpensive and highly sensitive and specific diagnostic methods.

Immunological-based techniques have been extensively utilized for the detection and epidemiological studies of human viral infections.

They can detect antiviral antibodies or viral antigens in clinical samples.

There are several commercially available molecular and immunological diagnostic kits that facilitate the use of these methods in the majority of clinical laboratories worldwide.

In developing countries including Ethiopia where most of viral infections are endemic, exposure to improved or new methods is highly limited as these methods are very costly to use and also require technical skills.

Since researchers and clinicians in all corners of the globe are working hard, it is hoped that in the near future, they will develop good quality tests that can be accessible in low-income countries.
