diagnostic sensitivity: the conditional probability that a person having a disease will be correctly identified by a clinical test, determined by taking the number of true positive results and dividing it by the total cases of the disease (which is the sum of the numbers of true positive plus false negative results).
diagnostic specificity: the probability that a person not having a disease will be correctly identified by a clinical test, i.e., the number of true negative results divided by the total number of all those without the disease (which is the sum of the number of true negative plus false positive results).
The characteristics, the sheer existence of this disease, mandate a significant tendency towards mutation. Any one who needs a flu shot every year, this mutating (if it’s natural) bug would require the same every few months. Oh Noes!
Yesterday on Fox I heard Dr. Isadore Rosenfeld say if you have the flu, there’s a 95 percent chance it’s H1N1 because that’s the main flu that’s infecting people right now.
