The podcast episode COVID-19 Q&A #2 explores various aspects of the ongoing pandemic, including the length of time the virus stays in the body, the possibility of flare-ups, and whether exposure leads to immunity. Genetics, previous exposure to viruses, sleep, and gut microbiome are all factors that influence the immune system's response to the virus. Adequate micronutrient intake, including vitamins A, C, D, E, omega-3 fatty acids, and minerals such as zinc, iron, selenium, magnesium, and copper, is also crucial for immune function. Gender and biological age may also impact immune responses. The podcast delves into the long-term effects of COVID-19, such as scar tissue in the lungs from acute respiratory distress syndrome and the increased risk of cardiovascular disease in older patients hospitalized for pneumonia. Consumer-based genetic testing services are also discussed, offering a free viral report with SNPs that affect viral entry, replication, and immune response.
