I'm not sure the world visitor is exactly correct: "visitors from infected countries" seems to imply people who actually live in that country. But Australia, for example, doesn't just require visitors from infected areas to be immunized, they require it of anyone, incluing residents of Australia, who has been in an infected area recently. -- Hypatia 08:24, 6 Oct 2004 (EDT)
I'm confused as to the placement of this information. I find it hard to believe that anyone is going to be searching out good places to get yellow fever, with the exception of WHO staff. So, why not put the fact that you should be immunized for yellow fever if you visit the jungles of Peru in Peru#Stay healthy or even in some more specific page? I guess I just don't find this list very readable. --Evan 14:49, 6 Oct 2004 (EDT)
You may want to visit South America and pick a country where you don't have to go through the hassle of getting immunized. The WHO list is spread out over several pages and organized alphabetically by country, so it's pretty useless for this. That's why I organized this geographically. It should be on the country pages too, of course. -phma 20:45, 6 Oct 2004 (EDT)
I think there also need to be a warning and link from countries with yellow fever. But then we have a problem keeping it consistent. -- elgaard 21:14, 2004 Oct 6 (EDT)
Deciding on a destination based on immunization seems extremely unlikely, unless you are a very capricious traveler -- "Wow, this country is fascinating! Exotic wildlife, friendly people, unique culture, great food ... oh, but it requires an immunization... forget it!" Especially considering that a yellow fever shot is good for ten years, most people who would casually consider going to a tropical developing country: a) have probably been to one already so are already immunized, or b) should get the immunization anyway. If you're going to Africa, or South America, or Southeast Asia, it doesn't matter what country, you should just get all your shots.
Conversely, novice travelers going to an endemic country for the first time are probably going for a specific reason and have already put a lot of planning into it, including immunizations.
Like the hitchhiking article, I think this article should cover the topic in general, and have separate country articles point to it. -- Paul Richter 22:14, 6 Oct 2004 (EDT)
Agreed with Paul, Elgaard and Evan. This should cover yellow fever in general, and should be linked in from countries where this is an issue. Jpatokal 22:55, 6 Oct 2004 (EDT)
I've added some more general information about obtaining the vaccination to the article so that it is useful if anyone wants to link to it from a country page. Note that the information may be rather biased to the Australian experience -- in particular in Australia the allergic reaction risk is because the vaccine is produced in eggs and recipients may react to the egg product in the vaccine. And the risk of serious side-effects is apparently 1 in 10000, which is about 10 times greater than measles/mumps/rubella. Obviously, feel free to amend the article if this information is not true world-wide. -- Hypatia 05:59, 7 Oct 2004 (EDT)
