Saad Hussein, an Ethiopian refugee in his late 20s, sent a number of items to the offices of the Illinois government in the weeks before the
US President's inauguration, according to court documents.
One envelope contained a letter with reddish stains and an admission ticket for Mr Obama's election night celebration in Grant Park, Chicago.
Court documents claim Hussein told FBI agents he is "very sick with HIV" and cut his fingers with a razor so he could bleed on the letter.
Hazardous materials teams were called in after the envelope addressed to "Barack Obama" was opened.
Days after the first letter was sent, Hussein allegedly placed two more letters in the mail, one addressed to "Emanuel", an apparent reference to the President's chief of staff, Rahm Emanuel.
The two letters contained what appeared to be dried blood, the court documents said.
Hussein, who is being treated for a mental
illness, was arrested last month.
An affidavit filed at the time accused him of "knowingly" posting letters "containing HIV-infected blood, with the intent to kill or injure another".
But Hussein told FBI agents - with his brother acting as an interpreter - he was "an admirer" of Mr Obama and was "seeking help from the government", according to the documents.
He was placed in a correctional facility in Chicago and has not been formally charged.
A judge ordered that he should be examined to determine if he is mentally fit to stand trial but this has not yet happened because a suitable translator has not been found.
The case was only the second time that HIV-infected blood had been sent with malicious intent through the American mail system, a spokesman for the US Postal Inspection Service said.

After scaling to the top of the pop charts with some of the most memorable hits this country has ever heard, no-one would blame Gary Barlow for resting on his laurels. But later this week, Gary’s scaling further than ever before as he attempt to conquer Mount Kilimanjaro for Comic Relief.Gary revealed, "I really can't wait for this to happen. It's been quite a long time in the organising but now it’s almost here!”However, the sheer scale of the 19,340ft, tallest mountain in Africa is also playing on his mind, “Altitude sickness is the biggest fear I guess - I've been skiing at around 2000 meters before but this is almost three times as high as that so it's a real unknown quantity for all of us.” That said, with the chance to raise money to help change lives across Africa and the UK for thousands of people, we think they’ll overcome everything the inactive stratovolcano can throw at them!To help the team raise a mountain of cash…sponsor the team at http://www.rednoseday.com/
