Managing Viral Emerging Infectious Diseases via current Molecular Diagnostics in the Emergency Department: the Tricky Cases

ABSTRACT

Introduction

Emerging infectious diseases’ diagnosis has been a major problem in most hospitals and other senior care facilities, especially for the current Coronavirus Disease 2019 (COVID-19). The various clinical manifestations, and the several radiology and laboratory data combined with the misleading test results for identifying the virus, are responsible for certain misdiagnoses, especially for suspected cases that visit the emergency department and require urgent management and further treatment.

Areas Covered

The major challenges for emerging infectious diseases’ molecular diagnosis are being described here on a great scale, and, finally, strategies for a precise and on-the-spot molecular diagnosis are thoroughly discussed. Related literature was searched using the PubMed, Science Direct, and EMBASE databases published until May 2022 on the general information for viral infections and relevant false test results.

Expert Opinion

Emerging diseases’ molecular diagnosis via current common diagnostic assays seems to be extremely tricky, and front-line physicians and other senior care facilities should be able to recognize some falsely diagnosed cases or even prevent their existence. Further biotechnologic revolution concerning viral molecular diagnostics will be evident in the near future, thus new methods’ limitations should be highlighted to physicians from the very beginning of their performances and wide utilization.

Article highlights

• Emerging infectious diseases may escalate in the near future; thus, precise molecular diagnosis is crucial especially for front-line physicians

• Common PCR and antigen/antibody assays can lead to false results for various reasons

• Strategies for a prompt diagnosis are the golden ideal for an accurate further management and acute care
