>>> only suffering from a severe bacteria infection well, I wouldn't say only. The bacteria in the tropics are fully as dangerous as appendicitis. (not only in the tropics by any means, but they are virulent here)
They have become resistant to the antibiotics. It's no longer a case of you just take your meds and you're good to go. You may respond to them and you may not, but if the infection has a good hold on your system, you may well die.
Bacteria are living organisms that multiply rapidly, so time is of the essence in treatment. First you have this amount, then they double, then that doubles, and so forth ... soon it is untreatable and a body literally decomposes into ooze and organs burst. It is disgusting and an awful way to die.
The medic may have wanted to come up with a "condition" for the moment and for the camera that would justify removal, while most likely knowing perfectly well there were a number of things it could be, but blood tests and cultures were needed.
