Interesting and good news from Dr John Cambell regarding immunity and re-infection of those that have had Covid 19.
Topics Covered:
- South Korea
- Testing positive again, China, Japan and Italy, as much 10 weeks later
- Recovered patients who tested positive for COVID-19 likely not reinfected
- Patients who appeared reinfected, false positives
- Probable long-term immunity
- Expert panel, dead virus fragments causing 290 to test positive after recovery
- Not caused by reinfection or reactivation
- Tests detected the ribonucleic acid of the dead virus
- PCR tests, cannot distinguish living or dead virus, leading to false positives
- Fragments of the virus can be detected for up to two months
- Respiratory epithelial cells have a half-life of up to three months
- Patients had developed antibodies
- The process in which Covid-19 produces a new virus takes place only in host cells and does not infiltrate the nucleus, (Dr Oh)
- This means it does not cause chronic infection or recurrence
- Virus stays outside of the host cell’s nucleus, before quickly bursting out and infiltrating the next cell
- Unlike hepatitis B or human immunodeficiency viruses (HIV)
- The virus is currently undergoing very small genetic changes
- Even if antibody levels, memory cells (memory lymphocytes)
- The KCDC has not found a single case where such patients had passed the coronavirus to another person
