Though Ebola patterns look promising in Sierra Leone and Liberia, the number of new confirmed cases spiked in Guinea last week, underscoring tough challenges that remain there, such as gaps in contact tracing and unsafe burials, the World Health Organization (WHO) said today.

For the third week in a row, Liberia reported no confirmed Ebola cases, and cases declined slightly in Sierra Leone, the WHO said in its weekly epidemiologic analysis of the outbreak.

Overall, 150 new confirmed Ebola cases were reported in the outbreak region last week, up from 116 the week before. The number of confirmed, probable, and suspected cases in the three countries has risen to 24,666, with death total increasing to 10,179.

...The WHO warned that although Ebola's footprint is now limited to a narrow area, the population is mobile, posing the risk or reseeding the disease to other districts and countries.

Health officials have made tremendous progress in fighting the Ebola epidemic in West Africa in recent months, but continued efforts are still needed, experts say. That's because the cases that are happening now could be enough to restart the whole epidemic....

Although health officials are trying to trace all of the people who had contact with each Ebola patient, this "contact tracing" is far from perfect in Guinea and Sierra Leone. As a result, cases pop up among people who officials didn't know were at risk. For example, so far this month, just 14 percent of cases in Guinea occurred among people who were known to have had contact with someone who was sick with Ebola, WHO says.

This "shadow epidemic," which is occurring under the radar, is very worrisome, said Dr. Amesh Adalja, a senior associate and infectious disease physician at the Center for Health Security at the University of Pittsburgh.

If this shadow transmission continues, "it will threaten to cause this whole outbreak to reignite again," Adalja said. "You have to make sure you're finding every case, and stopping transmission in every case."

The latest American aid worker to contract Ebola overseas, last week in Sierra Leone, was swiftly evacuated to a specialized treatment center for infected health workers run by the British Defense Ministry in the country’s capital, Freetown, then on to the National Institutes of Health clinical center in Bethesda, Md. Doctors at the center said Monday that his condition had worsened from serious to critical since his arrival on Friday.

CONAKRY/DAKAR - Guinea has suffered a setback in its fight against Ebola with a rash of new cases, including three doctors infected by the virus, with officials blaming weak surveillance and a failure to follow safety procedures.

  ... Guinea has seen cases rise for three consecutive weeks, according to World Health Organization data.

A government health report from the weekend showed there were 21 new cases in a single day, a spike from the recent daily average of eight.

One big source of concern is a chain of new infections that can be linked back to a woman who died of Ebola and was not buried safely, according to Fatoumata Lejeune-Kaba, spokeswoman for the U.N.'s Ebola emergency response mission UNMEER.

"It's a major setback .... It's due to individual behaviours. That is having a devastating effect on the community. People are simply not practising the safety rules that we have been talking about for a year," she told Reuters.
