Persistent Symptoms of COVID-19: Molecular Tests by Nasal and Pharyngeal Swabs Do Not Detect the Presence of the Virus in Intestines, Heart, and Other Organs

The paper titled “Persistent Symptoms of COVID-19: Molecular Tests by Nasal and Pharyngeal Swabs Do Not Detect the Presence of the Virus in Intestines, Heart, and Other Organs” addresses the limitations of PCR tests in detecting SARS-CoV-2 in various parts of the body. Here’s a detailed summary: Key Message: The paper emphasizes that a negative PCR result, obtained from nasal and pharyngeal swabs, does not confirm the absence of SARS-CoV-2 in other parts of the body or at the intracellular level. It specifically highlights that the virus can persist in organs like the intestines, heart, and skin, even when respiratory…
