The US tested the wrong people for coronavirus

And you can tell because of a number called the test positivity rate.

As the rate of new coronavirus cases in the US slows down, many states and cities there are encouraging businesses to open again, easing the lockdowns that have been in place since March. But public health experts warn that in many of those places, opening up is premature.
The reason is that throughout the US, as well as in many other countries, we still don’t really know how many people have the virus, or where they are. That’s dangerous because it means infected people who don’t feel sick are probably mingling with the rest of the population, which could enable further outbreaks. And the only way to really prevent that is by proactively testing people for covid-19 until the people who have it have been tracked down and isolated.
The US started testing its population for covid-19 very slowly, but it’s since ramped testing up, and by early May was performing over 200,000 tests a day. Unfortunately, there’s no magic number of tests that is “enough” to contain an outbreak. The important thing is to test the right people - and to evaluate whether that’s happening, public health officials recommend looking at a different number: The percentage of tests coming back positive. It’s called the test positivity rate.

  • How does this 10% or less theory works if a majority of people are infected? Then no matter how much you test the TPR will always be above 10%!

  • I usually think having things privatised by the government is bad but healthcare should be privatised and be free to everyone in the country, how many people in the US are suffering from medical bills. Most homeless in other countries is from drugs or mental health but in the Us it’s medical bills. Having it privatised will also help stopping corona cuz trump will try and stop the virus if it is affecting him and his economy nothing else will make him care!

  • Colorado is covering up their actual deaths as 6 ppl i know here died from the virus in one day and Colorado's death count did not rise at all that day, their covering up that they slowed testing down and even turned my mother away , and she turned out to test positive later she got the virus from me, we both almost died, haven't been tested since, forced back to work within 3 weeks of catching yhe virus, just because i have no way to get the test again

  • There is not any place to get the test for over an hour on wheels and tons of workers here dont have a car lole myself, theres over 600 workers here and i know most of them after a survey we found the casino workers here were stripped of unemployment even high risk people and people over 70 years old, we were told being high risk is not enough and if we turn down our jobs who reopened a month ago we will loose all income

  • "10 negative tests to 1 positive test" is 9%, not 10%. (10 negative + 1 positive = 11 tests. 1 positive / 11 tests = 9.09...%) So did that guy take "10%" and say it wrong, or has the video taken "10 to 1" and done a super common math-o. I think the thing to say which is both correct and wouldn't confuse people is to say "... that means less than 10%"

  • If someone has symptoms already, is the test necessary? Stopping the spread of the virus was the goal of the lock down. Shouldn't the test have the same goal?

    MICHAEL JUNGMICHAEL JUNG6 gün önce
    • No, testing should be used to catch the asymptomatic, not those who have symptoms. That way we can catch those who have the virus, and slow the spread.
