@Red225: I don't have a medical background nor a science degree in Biology, but as far as I understand it, one bacteria or one virus can actually infiltrate your body, successfully reproduce itself and therefore infect you. It is just astronomically improbable and for it to become halfway probable, there need to be a huge number of them, so your statement holds true most of the time. I would just have added that. Your post is the most proficient one in this thread.
Also Infections can die down again and an infected individual can also be isolated (e.g. living somewhere remote) or isolate themselves by choice. So even if some bacteria reach somebody at the shore, most likely nothing will happen.
And bacteria are living beings. Viruses are on the border of being counted as life, but they simple infiltrate a host and reprogram it. Many can lie dormant quite some time. Most bacteria on the other hand NEED TO metabolize! If they don't have a mode, that puts them into a deep dormant state, they aren't frozen or dried up (later both not very probable in an ocean), they have to fight with two unfavorable factors: An environment that is hostile towards them, as it is no host, and there is nothing to metabolize. They starve eventually, if nothing else killed them. If they float on the water surface, there are also UV-rays, which will disinfect them.
The only troublesome thing might be a washed up corpse, but I believe the admiral is capable enough to judge the currents.
@DeadKinginHell: While I thought of your first comment here as too soupy (Most careless people/deniers don't kill themselves, they kill others.), I can wholeheartedly concur to your second post.
