@Pygathrix: sorry dude, but You're wrong; I'm not making the veterinary guideline rules. The seperation I mentioned above is quite common in governmental epizootic control programs, f.e. in Germany. According to them, an outbreak of Chlamydophila psittaci in parrots (=psittacosis) is of greater importance than one in other birds (=ornithosis) and thus has a higher safety status, resulting in state-run veterinary control measurements (by executive veterinarians). This has two reasons: a) Parrots usually are the kind of birds people have the closest relation to (pet parrots nibbling at Your face) and thus the risk of transmission is higher. b) In former times, ps. and o. were considered two different illnesses, with p. leading to more fatal results due to a) (f.e. sailors).
And about the whale shark: all sound and fine-but how should more knowledge and experience about their husbandry be won if they are not kept? Same situation with Great White Sharks in Monterey Bay Aquarium; everyone told them it's a bad idea, and nevertheless their program seems to work after all.
@Chris79: Why shouldn't zoos not be "justified" to breed and keep "common" species instead of rare relatives? Take the African branch of the Colobinae as an example: no zoo has so far succeeded in keeping red or olive colobus monkeys alive for a longer period of time, while f.e. the Eastern Black-and-white Colobus is doing pretty fine. Why not rather concentrate on in-situ projects for red and olive colobus monkeys and keep the hardier Guereza as an "ambassador" species in the zoos, instead of keeping red's and olives in zoos? Same is true for meerkats & Liberian Mongoose, Blue & Sansibar Duiker, Giant & common Sable antelope, East Lowland & Mountain gorilla etc. In most cases, the conservation value of the above scenario (popular common species as ambassador in zoo, endangered & less popular species rather taken care of in in-situ projects "behind the scenes") is much higher than what You suggest. And don't forget how soon a "common" species can become endangered-f.e. the river hippopotamus.
About zoonoses: some of the mysterious tropical "diseases" You're inoculated against (IF You can be vaccinated against them at all....) before doing the Great Jungle Adventure do belong to that category-at least partly; yet it depends on the scenario & the illness whether invertebrates are involved (like in the case of an arbovirus or a trypanosoma infection) or not. However, so called "tropical diseases" play only a very small role in the zoo world, at least in western zoos; it's rather other epizootics, supported and spread by the productive livestock market that are of interest here.
The term "zoonosis" btw. automatically includes "zooanthroponosis" as well as ""anthropozoonosis (aka "reverse zoonosis"-a quite rarely used term and nowadays in Europe of interest in the case of TBC).
