Is it likely that your patient has this disease?

If my patient gets a positive test, the chances are 99% that test is correct, so my specific patient with a positive test in the hand should have a 99% chances of being sick. I admit that among all the humans, there is a small percentage of chances that a patient has the disease, but with the positive test in the hand, the chances should be 99%. What am I misunderstanding here?

the result is 0.000989010989011 so it means that 1 in 9890 patients with a positive test is sick: would not it mean that the test accuracy is 1/9890
