COVID-19 and post-mortem microbiological studies

Abstract We review the microbiological aspects of COVID-19 infection and present the microbiological studies that should be performed in forensic cases. We describe the taxonomic characteristics of the virus, its relationship with the coronaviridae family and its genetic structure. We briefly present the clinical and pathological characteristics of COVID-19 infection, as well as the co-infections that could be associated with this virus. In the laboratory, PCR is a first-choice technique in the acute phase of the infection, together with antigen and serological studies. Finally, we describe the main objectives of microbiological studies in the deceased in relation to the COVID-19 pandemic, as well as the main post-mortem microbiological analysis to be carried out in the medico-legal context. The microbiological analysis should aim to detect both SARS-CoV-2 and coinfections, which may also contribute to the cause of death.
