I am happy that you liked the article @pmduy!
Yes, such technology would be amazing! However, I have no idea how to create it, but will keep thinking. Great inspiration for future article btw :D hypothetical technology that could diagnose it in short time.
It's not hypothetical, several markers in blood have been associated with either bacterial or viral infections, one of them is human neutrophil lipocalin (HNL). I think the test based on HNL is coming: see here
Wow! Thanks for the link, going to check it in the morning (night here), didnt know that we have such tech already.
