Medical authorities in Uganda have expressed concern over the
possible spread of the deadly Ebola disease in the western region
after suspected cases were reported in 2 neighbouring districts. Sam
Zaramba, the director of medical services in the health ministry,
told IRIN on Mon 3 Dec 2007 that a patient with symptoms similar to
those reported in Bundibugyo district, the epicentre of the outbreak,
died on Sun 2 Dec 2007 at Mbarara hospital, farther southwest,
causing fears that the disease was spreading out of Bundibugyo.
Another suspected case had also been isolated at Virika hospital in
Fort Portal district, next to Bundibugyo, Zaramba said. "We are
waiting for the results of the samples for the 2 suspected victims,"
he told IRIN by telephone.
Another medical official, who requested anonymity, said: "There is
cause to worry when we start getting these cases overshooting and
appearing in other areas because this complicates contact
surveillance. One medical officer who worked on the 1st cases but
moved to Kampala [the capital] to attend to personal issues has also
fallen sick and was admitted to Mulago [the main hospital in
Kampala]; we are trying to follow his contacts."
Several dozen medics and support staff have fled western Uganda after
their co-workers became infected with the virus in an outbreak that
has already killed 16 people and infected at least 58 others. A
government official in Bundibugyo, Samuel Kazinga, said a quarantine
had been declared in all homes in the district that had registered a
case in order to control contacts and ease monitoring. "We are
mobilising the public to take precautionary measures through public
announcements on the radio and talking to people through community
[leaders]," Kazinga said.
He said Bundibugyo had appealed for help, but efforts to contain the
outbreak, which began in September 2007, although it was only
identified as Ebola last week, have been hampered by lack of medical
personnel. "We have a shortage of health workers, and we need more
because those who were there on the ground have been infected: 2
doctors, a medical officer and a nurse. We are trying to get more
medical workers to go to the region and help in the fight," said Zaramba.
Zaramba had initially said 2 more patients succumbed to the virus on
Sat 1 Dec 2007, bringing the toll to 18. But the health ministry on
Mon 3 Dec 2007 revised the number back to 16, saying the 2 deaths had
since been confirmed as due to other causes. "Cumulatively, we now
have 16 deaths and 58 cases," he said.
Patients were quarantined in Bundibugyo hospital's isolation ward
near the border with the Democratic Republic of Congo (DRC), which
has had outbreaks of the virulent disease in the past. "Those
admitted are mainly health workers and those who attended to the
patients," Zaramba said. Previous Ebola fatalities among medical
workers have been blamed on poor sanitation and hygiene in health
centres that lack protective suits, masks, latex gloves and other equipment.
Ebola spreads through body fluids, particularly blood, putting health
workers without protective gear at risk. Ebola sub-types usually
attack capillaries and blood vessel linings, so patients lose blood
rapidly and die of shock, doctors say. The new Uganda subtype kills
patients by provoking high fever, but without much loss of blood.
There is no vaccine or cure for Ebola. "The situation is not yet
under control," Zaramba said. "The main challenge we are facing is
detecting cases and following up on those who had contact with the
patients." A team of epidemiologists and virologists arrived in the
region on Sat 1 Dec 2007 to try to retrace the source of the virus as
part of a campaign to avoid future epidemics. Authorities said a team
of pathogen experts from the Centers for Disease Control in the US
were expected in the country on Tue 4 Dec 2007 to beef up the local
response to the disease, including bringing laboratory facilities to
detect infections more easily.
An outbreak killed at least 170 people in Uganda's northern Gulu
district in 2000. Another recent outbreak killed at least 26 people
in DRC's West Kasai region. The Ebola virus was 1st identified in
1976 in Sudan and in a nearby region of DRC, then Zaire. Outbreaks of
Ebola have also occurred in the Ivory Coast and Gabon.

[The significant new feature of this most recent report is that the
death toll in the outbreak has been reduced from 18 back to 16 -- the
2 most recent cases having failed to be confirmed. The number of
confirmed cases has been revised down to 58.
Dr C.H. Calisher has raised the interesting question of the taxonomic
status of the virus responsible for this new outbreak. Preliminary
reports have suggested that the outbreak virus is significantly
different from previously isolated Ebola viruses. Should the current
Uganda virus be designated a new strain, a new subtype or a new virus
species? Some guidance from those involved in determination of the
genome sequence of this new Ebola virus would be appreciated. - Mod.CP]
