the flu cannot be "Cured" but can oly be surpressed so it in inactive. only the body white blood cells can kill and fully remove the virus.
this is questiponed because it is true that it is limited to only one person, but this person may not of even had the flue to begin with. the the second question is which flue did the person have. swine flu is deadly and cannot be removed with antibodies or antibiotics. which is a pain because this flue kills the body.
the second things that is questioned is, is the antibiotic stable enough for everyone?
everyone has a different immune structured in different ways. some antibiotics will not help certain people because of the lack of lipids and enzymes in the hosts blood. this can be fatal because the body has a natural buffer in the blood that the antibiotic can easily damage and kill the host.

Explanation:
The sequence of impulse through the cardiac conduction system starts from SA node passes to AV node to atrioventricular bundle fibers and finally to Purkinje fibers.
Heart is an organ that receives oxygenated blood form lungs and deoxygenated blood from different parts of body. Oxygenated blood is transported to different organs and deoxygenated blood is transported to lungs for oxygenation.
Now, to perform this transportation, the auricles and ventricles of heart contract and relax. In order to contract and relax, impulse generation is required, which begins at SA node or Sinoatrial node. It is also referred to as pacemaker of the heart. SA node contracts the atria and the impulse transfers to AV node or Atrioventricular node.
This is followed by transfer of impulse to atrioventricular bundle fibers which further passes it on to Purkinje fibres for ventricular contraction. Now the blood is sent to lungs and aorta as per it's oxygen status.
