I believe Amergin is right concerning the Danish woman and this dates from around about 1979 I think. If my memory serves me well, I believe the HIV virus was also subsequently found during the re-testing in the 1990s of stored frozen blood or tissue in a London teaching hospitalof one unusual (i.e. at the time cause of death not fully established) case from the 1940s . I think the story was reported in the New Scientist at the time. Again, if my memory serves me well, this man was possibly in the merchant navy and was a frequent traveller around the world including Africa. If so, this firmly nails the lid on the coffin of a lab conspiracy theory.
