CARS Epidemic in Toronto Area
« on: Today at 05:00:56am »
It seems that Toronto has been struck with another epidemic. This time its CARS (Confusing Acute Respiratory Syndrome aka Conflicting Acute Respiratory Syndrome). It is a fatal disease very similar to SARS but requires a "confused" or "conflicted" statement by a physician, researcher, or elected official.
The "confused" part requires multiple PCR tests. If a patient tests positive repeatedly for SARS CoV, additional tests are run until "conflicting" results are obtained, followed by a confused or conflicted statement. See below for an example.
The treatment for CARS is a SARS epidemic (SARS clusters are no longer effective), which forces physicians, researchers, or government officials to reclassify CARS patients to SARS patients.

They argue it's too soon to suggest the virus has spread because of conflicting test results.
