Apple’s spokesperson noted that he had received antibiotics as treatment and is now recovering.

After his speech at WWDC, some major news sites and various blogs have commented about Job’s physical appearance. Apple’s CEO appears to have lost some weight and he looked a little pale.

Jobs’ health is a reason of concern, because he was diagnosed with pancreatic cancer in October 2003, but Apple did not announce the illness until nine months later, in July next year. Jobs underwent a successful surgery in August 2004.

Jobs is considered by many analysts as the man who saved Apple, after he returned to the company in 1996. Jobs, who co-founded Apple, resigned in 1985. But he returned as CEO when Apple bought his company, NeXT. He became Apple’s permanent CEO in 2000.

Since his return, Steve Jobs has been involved in all Apple major achievements such as the launch of iPod and iTunes and the company’s transition to Intel-powered Macs.

In 2006, after Job’s speech also at WWDC, several news sites reported that he has health problems, but Apple dismissed the information as rumors.
