ToreBear said:Don't know anything about Bilharzia, but most diseases/infections/parasites, don't take affect immediately upon infection.
It might take a bit of time before symptoms become noticable.
The incubation period is usually a matter of weeks. Froome himself states that he had tests done whilst in SA in December 2010 - which would have been a few days after the race on 27 November - and according to him / Sky PR, this is how he came to know he had the disease.
"We found out that I had it last December, I had a full blood screening in Africa as they regularly check for it over there.
Why would he need tests for Bilharzia after just doing the lion's share of the work setting a new course record at our longest one day event?
Using Google's date range search we can establish that there is zero mention of Froome and Bilharzia until the very day he takes the leader's jersey at the 2011 Vuelta. That includes any knowledge of him having the disease here in South Africa, where he was already a well-known face on the local racing scene.
The day before Vuelta leaders jersey - nada
The day the Vuelta concluded - 2 pages of results
