Reemerging Sudan Ebola Virus Disease in Uganda, 2011

Reemerging Sudan Ebola Virus Disease in Uganda, 2011

Trevor Shoemaker et al. Emerg Infect Dis.


Two large outbreaks of Ebola hemorrhagic fever occurred in Uganda in 2000 and 2007. In May 2011, we identified a single case of Sudan Ebola virus disease in Luwero District. The establishment of a permanent in-country laboratory and cooperation between international public health entities facilitated rapid outbreak response and control activities.

Sudan Ebola virus in Uganda, 2011. A) Geographic locations of Nakisimata village and Bombo Military Hospital with the isolation facility established by Médecins Sans Frontières (MSF) relative to locations where Sudan Ebola virus (SEBOV) was isolated during the current and previous outbreaks in Uganda. Scale bar indicates kilometers. B) Maximum likelihood tree obtained from full length sequences of SEBOV strains Nakisamata (JN638998), Boniface (FJ968794), Gulu (AY729654), and Yambio (EU338380) and the polymerase gene (*) of Maleo (U23458); full-length Reston Ebola virus (REBOV) (AY769362) is included as an outgroup. Bootstrap values listed at the nodes provide statistical support for 1,000 replicates. Scale bar indicates 0.006 substitutions per site.
