A former patient of Dr. Christiane Farazli says hundreds more people haven't been warned they could have been infected from procedures done by the embattled doctor.

At least one of Farazli's former patients said he didn't get a letter telling him he could have contracted hepatitis or HIV because he said there was no record of his 2003 colonoscopy.

"They had no record of me being a patient, OHIP didn't have me on their screen and neither did Dr. Farazli," said Ken Birchall.

"It's come to my attention that there are at least 200 other people that haven't (received one) because of either moving or circumstances that they have no control over."

Birchall said he had to request the City of Ottawa's information package on how to be tested, sent to 6,800 former patients in October after an inspection found improper cleaning procedures from April 2002 to June 2011.

He said he's going to get tested next week.

"I also want them sent to my own doctor because if they can do that much to screw up then I don't want to be any part of that end of it," he said.

"(Record keeping is) their job, that's what all of those people are paid for, that's why we have the Ministry of Health in Toronto."

Ottawa's chief medical officer of health Dr. Isra Levy said if people are concerned they may have contracted one of these illnesses, they should talk to their own doctor or the city's dedicated health information line at 613-580-2888.

Birchall said he's pleased with how Ottawa Public Health responded to his concerns.

"(They were) very receptive," he said. "I talked to a public health nurse, explained what was going on, she was the lady that called me back subsequently."

Farazli is currently under investigation by the College of Surgeons and Physicians of Ontario and is facing a class-action lawsuit from former patients.

Five plaintiffs in the suit said they have contracted Hepatitis C in the same time frame as they received a colonoscopy or endoscopy from the doctor.

Four of those said they only found out they had it after receiving the letter and getting tested.
