Sweden did basically nothing and they're fine. The whole virus is BS. It's not nearly as deadly as the media keeps pushing. There are studies by USC, Stanford and others showing 40-85x more people have gotten this than have tested positive. Most didn't even know they had it. There's a 99.9% chance you'll be fine if you get it. We need to just go back to normal and live our lives.
There is so much that goes into why certain countries have been hit harder than others. For starters, the average Swede is WAY healthier than the average American. America is a very unhealthy country compared to other first world countries, and this virus is highlighting this vulnerability. Whether it's high blood pressure, obesity, smoking, or just lack of general self-hygiene, all of these factors play into chances of beating the virus.
Taking this into account, and given Sweden's strategy is working so well, the US should have a higher ratio of deaths, right? Wrong, Sweden has a higher mortality rate than the US. Obviously in terms of total deaths, their count is lower, but their population is 33 times smaller. To dumb down this comparison, Sweden has 2,000 deaths vs. US count of 45,000. Scaling Sweden to the US, their death count is 66,000, or 46% higher. Is that "fine" to you? It's important to note that while Sweden has some restaurants and bars open, many nonessential businesses are actually still closed, and everyone is working from home or social distancing. Initial data shows that Sweden may see a slightly smaller decrease in GDP compared to the US, but they are paying for that in more lives. It's not like Sweden is operating as they were pre-COVID-19.
Not sure where you get your news from, but everything I mentioned above is data and facts. Not news headlines from biased media outlets. The best thing anyone can do in uncertain times is make decisions and form opinions based on data, not shared articles on Facebook. Regarding the studies you mentioned,
none of these are peer reviewed, meaning they shouldn't be relied upon. The folks that conducted the tests listed many data quality/biases in their process, which is why their margin of error is in the tens of millions. Kind of ironic you fault the media, yet I would bet you relied on a media's headline regarding these studies vs. actually reading the study, or you would've realized this.
At this point, no one disagrees that there are more infected cases in the wild vs. confirmed cases via tests. However, since the US is still inept at widespread testing months after being made aware of this virus, we don't have the data available to make informed decisions, meaning we can't resume life as we knew it. Hopefully that changes in the coming months, though if this past month is any indication, I'm not holding my breath that things will improve overnight. This whole situation has thankfully shown that most US citizens are altruistic and selfless, and would rather save the lives of fellow Americans vs. taking a gamble on a material % of the population (your figure of 99.9% is made up, but know that is still 330,000 deaths) so that they can rush back out to a bar or shopping mall.
