COVID-19

I am moving my English blogs on COVID-19 and ORTEC to this site.
Nederlands
Basis of virology is simple. More infections imply
  • More people with disease
  • More hospitalizations
  • More lockdown
  • More economic damage
  • More damage to society
  • More people with long-covid
  • More deaths
  • Virus epidemics grow exponential.
    • Weekly doubling imply 1000-fold after 10 weeks.
    • More infections are harder to control
  • More virus variants will evolve
Herd immunity might end an epidemic when the maximum number of people has been infected or vaccinated if the virus induces lasting sterilizing immunity.
  • Coronaviruses don’t induce herd immunity.
  • Herd immunity through natural infection has never been a strategy against a severe pathogen.
Some aspects of SARS-2 are more complex, but these do not change the list above:
