The 40-year-old charity swimmer is undergoing tests for deadly Weil’s disease after suffering from fever and extreme muscle and joint pain following his marathon 140-mile swim of the River Thames recently.
David WalliamsÂ symptoms are classic sign of the dangerous waterborne disease which is contracted through water contaminated by infected animal urine.
In more severe cases, Weil’s disease can kill.
The poorly Little Britain star has been forced to cancel a number of special guest appearances including the new Jonathon Ross show on ITV1 and is now undergoing tests for Weils Disease in London.
David WalliamsÂ raised a massive Â£1million for Sports Relief for finishing the 140-mile mighty Thames River swim.
“The first signs were during the swim including the sudden fever, the diarrhoea and the rash.
“What was especially significant was the sudden stop of the illness only to return a few days later.
“The extreme and continued muscle and joint pain and the fact he is still extremely fatigued and feverish show all the classic signs of Weil’s.
“He is undergoing tests but at least he’s in good hands”, said a source.
