The meme is talking about a common probability error that surveys have shown even doctors are prone to making.

Why you’re probably ok:

The rarity of the disease far exceeds the error rate of the positive test. Meaning, the disease occurs in 1 out of a million people, so if you are tested at random and show positive, you only have a 1 out of 30,000 chance (the 3% false-positive rate) of being the the 1 person who truly has the disease.

      I mean, yes…

      But at 1/30,000 , they should say “get the second test… but be SUPER CAREFUL on the drive”, since at 1/30000 you’re still an order of magnitude more likely to die in an MVA.
