SARS-CoV-2, the virus responsible for the coronavirus pandemic, is still present in various organs of the body at least five days after death, reveals a new German study published in Annals of Internal Medicine. Cited by Sciences Et Avenir, the study confirms the post-mortem persistence in humans of the SARS-CoV-2 virus. However, this is the first time that the analysis has been done so completely.
In this group, where the median age was 73, forensic pathologists and pathologists from the forensic medicine service at the University Medical Center in Hamburg-Eppendorf (Germany) used an associated scanner for each of the 12 autopsies. a fine, so-called histological, analysis of the tissues of different organs as well as an evaluation of the viral load by the PCR technique.
Thus, in addition to identifying the cause of death, namely the presence of blood clots in the pulmonary blood circulation responsible for pulmonary embolism, forensic pathologists also found in the lungs of all RNA patients SARS-CoV-2.
The study reveals that it is not the only organ concerned, the virus having also been identified in the pharynx of nine patients as well as in the liver, heart and kidneys. The authors also report that in one in four patients, viral RNA was detected in the brain and a vein in the leg, called the saphenous vein.
But if this so-called retrospective study, which attests to the post mortem viral presence, “does not provide evidence of an infectious risk, the viremia remaining moderate with concentrations lower than 4 × 104 copies / ml”, specifies Sciences etvenir .
