He is a two-time Olympian, and a three-time All-American swimmer for the Arizona State Sun Devils at Arizona State University in Tempe, Arizona, where he majored in and graduated with a bachelor's degree in civil engineering.

Hussein made his first Egyptian team at the 2000 Summer Olympics in Sydney, where he competed in the men's 200 m backstroke. Swimming in heat two, he edged out Singapore's Gary Tan to earn a fifth spot and thirty-sixth overall by 0.22 of a second in 2:06.10.

At the 2004 Summer Olympics in Athens, Hussein extended his program by qualifying for two swimming events. He claimed two gold medals from the All-Africa Games in Abuja, Nigeria, breaking an Egyptian record and meeting a FINA B-cut of 55.75 (100 m backstroke) and 2:02.45 (200 m backstroke).

In the 100 m backstroke, Hussein participated in heat three against seven other swimmers, including Olympic veteran Derya Büyükuncu of Turkey. He raced to sixth place and thirty-first overall by 0.52 of a second behind Buyukuncu, outside his personal best of 56.86. In his second event, 200 m backstroke, Hussein matched his position from the 100-metre backstroke on the morning's preliminaries. Hussein saved a seventh spot on the same heat as Sydney over South Korea's Sung Min, who finished behind him in last place by 0.04 of a second, with a time of 2:04.82.
