Bacteria
Technically a 'pathogen' IS measels. A pathogen is a fancy name for Bacteria. And a pathogen is a bacteria that IS a certin disease. Hencforth, the answer to your question would be measles IS its own pathogen.
The closest and most likely to be effected is Canada. The wind is likely to carry ash toward either Mexico or to the Caribbean countries. If the eruption is large enough, all countries in the northern hemisphere would likely be affected by the climatic impact.
After your first exposure to a pathogen, you have memory T-cells that will remember the antigen of the pathogen so in the future if you would come in contact with the same pathogen your body would recognize it right away and be able to kill it much faster.
The primary structure of the protein, which refers to the sequence of amino acids, would likely not be affected when a protein is denatured. Denaturation usually disrupts the secondary, tertiary, and quaternary structures of a protein.
That would be a virus.
A virus or fungus ?

Every kind of animal is affected by garbage dumps. It would be most likely be a stray cat, dog or a wild bird.
Economic productivity would decline.
less glucose would be available for energy production.
A very broad answer to a very broad question... A "pathogen" as defined by a dictionary would be, "any disease-producing agent, esp. a virus, bacterium, or other microorganism." First- a "pathogen" in drinking water will cause nothing unless someone or something drinks the water or if the "pathogen" enters the body/host by some other means... Second- even once the "pathogen" enters the body it may still cause nothing, as the quantity of the "pathogen" must be sufficient to cause the would be disease... Third- because a "pathogen" could be any one of millions of things, what disease would be caused by your hypothetical "pathogen in the drinking water" would depend entirely on what it is... You should seriously consider being more specific about your question. If you are interested in a specific pathogen and the associated disease, please try again.
A population with a low population density would be least likely to be affected by a density-dependent limiting factor, as these factors typically become significant when populations reach higher densities.
