How much does the bacteria/toxins effects depend on the body's natural immunity? I remember reading somewhere that you're only likely to catch typhoid (or is it cholera?) if you're already feeling poorly or if your immune system is somehow compromised. Is there any truth to that?
Not as stated. Clearly a weakened body will be less able to fight infection of any kind, but it's not a case of catching or not catching a disease, but how severe and/or long-lasting the symptoms may be.

The same virus, for example a common cold one, may leave one infected person with just a slight runny nose for a few days while completely knocking someone else for six. The reasons for this are not always clear, as with the cold thing studies have failed to conclude that it's "weaker" people who get worst hit.
