Testing prevents premature closing of schools and businesses.
It also help stop the spread of the disease. When there are a handful of cases, they can prove someone has it and then retrace their steps and identify places they’ve been to disinfect and identify people they’ve contacted to quarantine and test them. This prevents small outbreaks and nips them in the bud like what happened in South Korea and Germany. When a disease is widespread, testing can identify whether someone needs to be quarantined or not so the disease stops spreading.
You won’t find many experts saying testing is unnecessary or useless and we don’t need it.
Arguing that testing is unnecessary because health experts say it’s unactionable and unnecessary is one of the worst takes Cougarboard has produced. Congrats.
