There will be no new lock-downs. The response will be much more targeted during the second wave: masks in crowded indoor spaces like buses at rush hour, enforced quarantine for those returning from countries classified as having higher risk, arrangements at school and at workplaces to reduce exposure and a recommendation to work distantly if possible.
The pandemic will be over like every other pandemic before it. In countries or regions incapable of restricting it, it will spread swiftly and it will make a lot of people sick. The most vulnerable will die but but those who become moderately ill from it will be too sick to work for many weeks. A few will have long-lasting symptoms that will reduce their capacity to work and lower their life quality. Eventually effective vaccines will be available or the virus will mutate and develop variants that cause a milder disease and severe symptoms for much fewer and that will spread more rapidly in populations. Those variants will give populations herd immunity against the other variants, too.
Maybe in Finland, but what about elsewhere? Victoria (Melbourne area) got locked down in an unprecedented way a couple weeks ago.
Until the next mutation that lays outside of the created defenses.
That's not good news. At some point, the economic pressure will build up sufficiently to make it impossible lock down the economy.
It's never binary like that. Both the immune systems and the pathogens are responsive.
There hasn't been a single pandemic in history that hasn't run its natural course and vanished eventually. When a new pathogen jumps the species barrier and is introduced in humans, it tends to cause a severe illness because few people's immune systems can deal with it. But over time such pathogens become adapted to humans and the human immune systems adapt to them.
Who suffers with this kind of pressure, who gains?
Eventually there will be a wipeout one, unless we do it to ourselves first with nukes. But this is the issue - this flu really isn't so bad in comparison to what would have happened under a bad flu season anyway.
There's always someone gaining while others suffer. But at some point, too many will suffer.
That's not true. Covid-19 is also not just a flu. It affects not only the respiratory system but other organ systems as well.
The infection fatality rate (= the rate of death of all of those who are infected) is unknown because it is not known what proportion of the population has been infected. Also, the second wave of the pandemic is in an early stage.
The second wave has sometimes been the more deadly one because of this phenomenon called antibody-dependent enhancement:
