"This can be a real challenge for diagnostic tests," Mary Rogers, co-author of the report and chief scientist at Abbott, said. Her company is testing more than 60% of the world's blood supply, she said, and they need to look for new strains and track those in circulation so that "we can find it exactly wherever it is in the world."

There's no reason to panic or even worry a little bit about it, "Fauchi said. "Not many people are infected with this. It's different."
In order for scientists to declare that this is a new subtype, three cases must be discovered independently. The first two were discovered in the Democratic Republic of the Congo in 1983 and 1990.
The two strains are "very unusual and do not match other strains," Rogers says. The third sample, discovered in the Congo, was collected in 2001 as part of a study aimed at preventing the transmission of the virus from a mother to a child. The sample was small, and although it looked similar to the two older samples, scientists wanted to test the entire genome to be sure. At the time, there was no technology to determine if this was the new subtype.
So scientists at Abbot and the University of Missouri developed new techniques for exploring and mapping the 2001 sample. Rogers said it was "like looking for a needle in hay" and then "pulling the needle with a magnet"  New York state may end AIDS epidemic by end of 2020, governor says ” data-src-mini=”//cdn.cnn.com/cnnnext/dam/assets/160206152814-gov-cuomo-jan-29-small-169.jpg” data-src-xsmall=”//cdn.cnn.com/cnnnext/dam/assets/160206152814-gov-cuomo-jan-29-medium-plus-169.jpg” data-src-small=”http://cdn.cnn.com/cnnnext/dam/assets/160206152814-gov-cuomo-jan-29-large-169.jpg” data-src-medium=”//cdn.cnn.com/cnnnext/dam/assets/160206152814-gov-cuomo-jan-29-exlarge-169.jpg” data-src-large=”//cdn.cnn.com/cnnnext/dam/assets/160206152814-gov-cuomo-jan-29-super-169.jpg” data-src-full16x9=”//cdn.cnn.com/cnnnext/dam/assets/160206152814-gov-cuomo-jan-29-full-169.jpg” data-src-mini1x1=”//cdn.cnn.com/cnnnext/dam/assets/160206152814-gov-cuomo-jan-29-small-11.jpg” data-demand-load=”not-loaded” data-eq-pts=”mini: 0, xsmall: 221, small: 308, medium: 461, large: 781″ src=”data:image/gif;base64,R0lGODlhEAAJAJEAAAAAAP///////wAAACH5BAEAAAIALAAAAAAQAAkAAAIKlI+py+0Po5yUFQA7″/>
