McIlroy battles health scare
Rory McIlroy will have to overcome possible Dengue fever as well as Alvaro Quiros if he is to end the European Tour season with back-to-back victories.
Two closing bogeys left the 22-year-old five behind Quiros at the halfway stage of the Dubai World Championship but the Northern Irishman's health was more of a talking point than his golf after he left a chip short of the green at the short 17th and then drove into water on the par 18th 20 minutes after Quiros had eagled the hole to go 12 under par.
"I'm going to see a doctor again tomorrow night and she's going to determine whether I go to Thailand next week," the US Open champion and world number two said.
"They said it could have been Dengue fever (an illness transmitted by a mosquito bite and fatal in less than one per cent of all cases), food poisoning or a number of different things.
"My immune system is a little low and it's taking my body a bit more time to recover from it usually would."
McIlroy has been struggling with his energy levels for the past few weeks and underwent blood tests on his arrival in the Middle East from Hong Kong on Monday.
The results were given to him after his opening 66 and showed that both his platelet count and white blood cell count were low.
McIlroy was assured, however, that if it was Dengue fever it was only a mild case because of the platelet count.
"It didn't go so low to say that I had a bad case of it, but to be honest I'm ready for the season to be done and looking forward to putting the clubs away."
