Coronaviruses occur in all four classes of terrestrial vertebrates – mammals, birds, reptiles and amphibians – and can sometimes change hosts due to their high genetic variability. In humans seven types of coronaviruses are currently known to cause mild respiratory infections (cold/flu) but also severe respiratory diseases such as SARS.

The latter include the new coronavirus SARS-CoV-2, which first appeared in 2019 and can in some cases result in severe symptoms and death. The main transmission route for SARS-CoV-2 is droplet infection, i.e. the respiratory uptake of virus-containing fluid particles (breathing, coughing, speaking, sneezing).

Since the symptoms of the disease caused by SARS-CoV-2 are very heterogeneous and ambiguous, the pathogen must be clearly detected in the patient to confirm the disease. The method used for Covid-19 detection is the real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR).

The correct identification of potentially infected patients – in addition to the correct timing of the test – depends crucially on the collection method of the material. To ensure reliable test results the sampling method has to provide a sufficient amount of viral material in case of corona-positive patients. This is commonly achieved by a swab of the nasopharynx or oropharynx. A supplementary sample of the lower airways (bronchoalveolar lavage, sputum, tracheal secretion) is recommended. The potentially virus-containing sample should be placed immediately in a sterile transport tube containing 2-3 mL virus transport medium (VTM).

Coronaviruses are enveloped positive-sense RNA viruses, i.e. the genetic information is encoded in RNA instead of DNA. For the specific detection of Covid-19 the RNA must be isolated from the virus particles accordingly. The virus transport medium or virus inactivation medium in which the virus sample is stored until diagnosis is ideally suited as starting material for RNA extraction. When many samples are generated, high-throughput extraction is performed using automated nucleic acid extraction machines.

The laboratory diagnosis of SARS-CoV-2 is performed by detecting two nucleotide sequences, the E gene and the RdRp gene. The qualitative detection of SARS-CoV-2 RNA is performed by real-time quantitative reverse transcriptase PCR (RT-PCR).
