effort to finish the job," the WHO's special representative for Ebola,
Bruce Aylward, told a briefing attended by health ministers.
"With
the start of the rainy season today, the doubling of effort will be that much
more difficult, that much more important," he added, referring to
increased logistical challenges for health workers.
The
35 new cases in the week to May 17 were in six districts of Guinea and Sierra
Leone , with most infections in Guinea , Aylward said, giving no
breakdown of the preliminary figures. A total of nine were confirmed the
previous week.
