Post inauguration a positive case is only reported if a person tests positive twice and shows symptoms.
Look it up...
I don't want to make this a F16 thread but I did look it up and there is literally zero information to support that claim. If it's true, please provide proof.
https://www.who.int/news/item/20-01-2021-who-information-notice-for-ivd-users-2020-05I think it may be a bit overstated but its not that far off. The WHO statement says the below:
WHO guidance Diagnostic testing for SARS-CoV-2 states that careful interpretation of weak positive results is needed (1). The cycle threshold (Ct) needed to detect virus is inversely proportional to the patient's viral load. Where test results do not correspond with the clinical presentation, a new specimen should be taken and retested using the same or different NAT technology.
WHO reminds IVD users that disease prevalence alters the predictive value of test results; as disease prevalence decreases, the risk of false positive increases (2). This means that the probability that a person who has a positive result (SARS-CoV-2 detected) is truly infected with SARS-CoV-2 decreases as prevalence decreases, irrespective of the claimed specificity.
I know that's a lot of medical gobbledygook but I read it to say if someone tests positive but isn't showing symptoms they should be retested to avoid a false positive test. The date on that guidance is January 13, 2021 so I can see how people interpreted it the way they did.
