A baby born in Mississippi with the virus that causes AIDS appears to have been cured according to CBS News.

Scientists announced Sunday that the two-and-a-half-year-old child has shown no signs of infection after being off medication for a year.

The child received aggressive treatment just 30 hours after being born.

This is a major step in the fight against HIV, Dr. Anthony Fauci, sathe director of the National Institute of Allergy and Infectious Diseases told "CBS This Morning." He spoke about the Mississippi baby and the ramifications of this cure.

"This is very likely a cure," Fauci explained. "It's really more of a hypothesis-developing or driving situation...we need to see if this is going to be applicable."

The course of treatment involved serves as "an important proof of concept that if you treat early enough, you prevent the virus from establishing what we call a reservoir where it's very difficult to eliminate that after it's been established ... so they got a jump on virus," Fauci added.

Mothers are typically treated during their pregnancy, hoping not to pass the virus on to the child. With this cure, that may change.

"In those circumstances you don't aggressively treat the baby ... you wait about six weeks [after birth] until you can definitively prove that the baby he said.

Fauci explained that the Mississippi case could lead to a shift treatment options and added that, "we're going to have to start looking at the relative risk versus the benefit of doing it this way."

This child would be considered to the second person ever to be cured. The first was 45-year-old Timothy Ray Brown of Berlin, Germany.

According to webmd.com, Brown was living in Berlin and being treated for his HIV infection with a normal anti-HIV drug regimen. When he developed leukemia, he underwent a bone marrow transplant. His doctor decided to look for a donor who had a rare genetic mutation that makes a person resistant to HIV infection.

Such a donor was found. After having his own blood cells eradicated with radiation and powerful chemotherapy, Brown received the transplant with the anti-HIV mutation. While recovering, he was unable to take his anti-HIV drugs -- yet there was no sign of the virus in his body.

Five years later, Brown remains HIV free.
