I have earlier been convinced that aids is not transmitted by mosquitoes. However, it there any conclusive information?

An attempt to culture HIV in mosquito blood cells failed. As you may know a culture is more favorable than "real life" situations. In other words, things multiply in cultures where they wouldn't be as successful elsewhere. Hence, failure of HIV to culture in mosquitos would be IMO about as conclusive as scientific knowledge gets. -- Bob Culmer - Dallas | "Hearts will never be practical until Somewhere over the rainbow | they can be made unbreakable." - Wizard ...in the Land of OZ | "But I still want one." - Tin Man {mic,void,egsner}!ozdaltx!bob

I believe I've read that syphillis, for example, is extremely difficult to culture, even though it grows easily enough in actual humans.

I believe that much of the evidence that HIV is not transmitted by
mosquitoes is epidemiological -- there is no correlation between AIDS
incidence and mosquito exposure. For instance, in African areas where
AIDS and malaria are both endemic, children between ages 3 and 15
don't develop AIDS, even though they are at high risk for malaria.
