As
of 30 Jul 2014, the cumulative number of cases attributed to EVD in the
4 countries stands at 1440 including 826 deaths. The distribution and
classification of the cases are as follows:
- Guinea, 472 cases (337 confirmed, 122 probable, and 12 suspected) including 346 deaths;
- Liberia, 391 cases (109 confirmed, 181 probable, and 101 suspected) including 227 deaths;
- Sierra Leone, 574 cases (507 confirmed, 41 probable, and 26 suspected) including 252 deaths;
- Nigeria, 3 cases (1 probable and 2 suspected) and 1 death.
[See [4] below for WHO definitions of confirmed, probable & suspected for EVD. - Mod.JW]
Between
28-30 Jul 2014, 55 new cases (laboratory-confirmed, probable, and
suspect cases) of EVD, and 58 deaths, were reported from the 4 countries
as follows:
- Guinea, 5 new cases [including] 3 deaths;
- Liberia, 31 new cases [including] 46 deaths;
- Sierra Leone, 17 new cases [including] 9 deaths;
- Nigeria, 2 new suspected cases which on 1st test were negative.
The
surge in the number of new EVD cases, especially in Liberia and Sierra
Leone, calls for concentrated efforts by all to address the identified
problems such as health facility transmission and effective contact
tracing. More human resources experts are requested in these 2 countries
to really tackle the progress of this outbreak. The situation in Guinea
seems to be stable these 2 last days.
In Nigeria, 2 suspected
cases among the contacts followed up at the airport were tested negative
in the 1st PCR test. Another test will be done 48 hours later to
confirm the status. The contact tracing is continuing as well as
communication activities.
In Togo, some passengers from the
flight to Lagos disembarked in Lome, and our epidemiologists in the
field are working with the services at the airport to find out their
addresses for contact tracing. The Togo and Nigeria EVD operational
plans have been finalized and sent. The national authorities in Nigeria,
Togo and Ghana continue to work closely with WHO and partners in
identification of contacts and contact tracing as well as in preparing
response plans [This suggests that, as he had no symptoms on embarkation
in Sierra Leone, he developed them some time between Accra, Ghana &
Lome, Togo. There is a table of confirmed, probable, and suspect cases
and deaths from Ebola virus disease in Guinea, Liberia, Sierra Leone and
Nigeria as of 30 Jul 2014 in the source. - Mod.JW].
The total
number of cases is subject to change due to ongoing reclassification,
retrospective investigation and availability of laboratory results. Data
reported in the Disease Outbreak News are based on official information
reported by Ministries of Health.
WHO does not recommend any
travel or trade restrictions be applied to Guinea, Liberia, Sierra Leone
or Nigeria based on the current information available for this event
[Nevertheless, the 3 originally infected countries have agreed to
establish a militarized quarantine zone along their common borders; see
ProMED archive
