Enhanced surveillance in affected districts is being carried out through active search for cases in the communities
PUBLIC HEALTH ACTIONS
Cases are isolated and managed at local health facilities
Cholera kits have been dispatched
Communication and social mobilization activities are ongoing
WASH activities are being scaled up

6. Hepatitis E: Namibia
Geographical distribution of hepatitis E cases in Namibia, Jan - July 2018
The outbreak of hepatitis E in Namibia continues to spread to other regions of the country.
During week 28, 63 new suspected cases were reported as compared to 64 cases in week 27, 2018), indicating continuous upsurge of cases.
Three regions are currently experiencing outbreaks of hepatitis E including
Khomas (capital Windhoek)
Omusati (bordering Angola)
Erongo, in central-western Namibia
Over 90% of cases reported are epidemiologically linked to the cases in Windhoek.
From Jan 2018, a total of 1,915 cases including 17 deaths (CFR - 0.9%)
178 laboratory confirmed
1,355 have epidemiological
PUBLIC HEALTH ACTIONS

7. Ebola Virus Disease: DRC
Geographical distribution Ebola virus disease cases, DRC, 1 April – 9 July 2018 (n=53)
The MoH and WHO continue to closely monitor the EVD outbreak in the DRC
No new laboratory-confirmed EVD cases have been detected since the last case developed symptoms on 2 June 2018.
On 12 June, the last confirmed Ebola virus disease was discharged following two negative tests
A period of 42 days (2 incubation periods) must elapse before the outbreak can be declared over.
Since 4 April 2018:
53 suspected cases including 29 deaths have been reported (CFR – 55%)
38 confirmed, 14 probable
Risk Assessment:
National level: very high
due to the serious nature of the disease
Regional level: High
confirmed case in Mbandaka, located on a major national and international river, increases the risk for further spread to neighboring countries.
At global level: Risk is currently considered low.
The review included the development of a 90-day enhanced surveillance and response plan for the continuation of core activities after the end of the outbreak, as well as planning for sustaining local and national capacities for to ongoing health emergency response across the Democratic Republic of the Congo
On 3 July 2018, WHO reviewed the level of public health risk associated with the current outbreak. The latest assessment concluded that the current Ebola virus disease outbreak has largely been contained, considering that over 21 days (one maximum incubation period) have elapsed since the last laboratory-confirmed case was discharged and that contact tracing activities ended on 27 June However, there remains a risk of resurgence from potentially undetected transmission chains and possible sexual transmission of the virus by male survivors. It is therefore, critical to maintain all key response pillars until the end of the outbreak is declared. Strengthened surveillance mechanisms and a survivor monitoring program are in place to mitigate, rapidly detect and respond to respond to such events. Based on these factors, WHO considers the public health risk to be moderate at the national level.
Risk Assessment:
National level: High
Regional level: Low
At global level: Low
