The corona virus is more contagious. Whereas a person infected by a regular influenza will infect on average 1,1 persons, a person infected with the corona virus will infect more people on average. Bear In mind, the Corona virus is new and the data on the virus are yet sparse. The numbers are therefore not bulletproof. But according to The World Health Organization, WHO, the rate of reproduction may actually be as high as 2,0- 2,5. The reason may be that the human immune system does not combat the corona virus as effectively as it does a regular flu virus. It may require fewer viral particles to get infected by the Corona virus.
When your little Viking utopia opens its schools again, go back and learn not to cherry-pick facts and data. R number doesn't tell you anything about how fast a pathogen spreads. It tells you how many new cases will be generated, but not when.
For example, HIV has an R0 as high as 5, but it took years to infect millions like the flu does. That's because a person who catches the flu starts infecting new people in only a couple of days, while a person with HIV may take months to years.
If you've studied covid so thoroughly, you should be able to ace this quiz:
1) covid has a (long or short) incubation phase
2) transmission during incubation phase (is or is not) thought to be a main driver of contagion
3) therefore, covid takes a (longer or shorter) time for an infection to generate a new infection
