Ebola Cases Surpass 8,000

Over 8,000 people in Liberia, Guinea and Sierra Leone have been infected with Ebola, according to new data from the World Health Organization (WHO).

The numbers show there were 2,799 new cases in the last 21 days. Of the 8,011 people infected, 3,857 people have died. “The situation in Guinea, Liberia, and Sierra Leone continues to deteriorate, with widespread and persistent transmission of [Ebola],” says the WHO in a statement.

The WHO cites problems gathering data in Liberia, and says it should be emphasized that “the reported fall in the number of new cases in Liberia over the past three weeks is unlikely to be genuine. Rather, it reflects a deterioration in the ability of overwhelmed responders to record accurate epidemiological data.”

This happened before in Guinea, when it appeared cases had slowed, but in reality cases went unreported or were hidden. The WHO says there is likely a lot of underreporting in Liberia, as fears and distrust of government grow, and that official estimates are likely lower than Liberia’s actual number of cases.

“There is no evidence that the [Ebola] epidemic in West Africa is being brought under control,” the WHO says. “Though there is evidence of a decline in incidence in the districts of Lofa in Liberia, and Kailahun and Kenema in Sierra Leone.”

Tobacco plants are grown for six weeks in the Medicago greenhouse in Quebec City so their leaves are large enough to serve as a factory for making antibodies. The plants are not modified or genetically altered in any way during this time.Mathieu Belanger—Reuters

Researchers at Icon Genetics in Germany prepare the DNA coding for antibodies that can neutralize Ebola. These genes are inserted into a soil bacterium that easily infects the tobacco plant cells. Once in the cells, the gene is treated like any other plant gene and the plant starts churning out the antibodies.Sean Gallup—Getty Images

To infect the leaves with the antibody-containing bacteria, the plants are submerged in a water solution of the loaded bacteria. Plant cells have plenty of empty spaces filled with air, so a vacuum removes the air and the water, along with the bacteria and antibody genes, flow in.Mathieu Belanger—Reuters
