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 20140801.2652930. - Mod.JW].
