North of London | The explanation in the link refers to the NML (National Microbiology Laboratory) which compared/checked the numbers.
If you read further down in the link it talks about negative tests not being as good with 70-90% accuracy and this is explained partly by timing, if the test is done when a person is just becoming infected there might not be enough infection to read positive.
That had always been my understanding of the tests, they were only going to give you a negative for that moment and you could become infected on your way home from having the test so become positive a few days later.
However if you test positive then you know you are infected and will be infected for a while.
There is a 'good news' story in Ontario today where a nurse returned home today after becoming infected with Covid in March.
He worked in Detroit and became infected at work.
Was on a respirator for 30 days I think, had failing organs, was expected to die but pulled through with damage to his brain as well as some other organs but returned home today to continue to recuperate
Was a healthy 30 some years old before getting it while caring for others who were infected. | |
