Subsequently, a rapid increase in the number of cases has been observed.

Key updates

  • Angola epidemiological update (as of 15 September):
    • There have been 4 new laboratory positive cases this week, 2 of which have been discarded as having recent vaccination history.
    • The other 2 are currently under investigation.
    • Phase II of the vaccination campaign has been prepared and will begin shortly in 12 districts in 9 provinces.
  • Democratic Republic of the Congo epidemiological update (as of 14 September):
    • The second case reported from Budjala Health Zone in Sud Ubangui province (reported in the situation report of 9 September) has been confirmed for yellow fever.
    • Based on the investigation this has been classified as a sylvatic case not related to the outbreak.
    • The first notified case reported in Sud Ubangi province in Bominenge Health Zone (reported in the situation report of 26 August) remains under investigation.
    • The pre-emptive vaccination campaign in Democratic Republic of the Congo has concluded.
    • The results indicate that the overall administrative immunization is 102.7% in the six provinces.
    • The response vaccination campaign in Feshi and Mushenge Health Zones in Kwango province will begin next week.

 

Analysis

  • The continuing detection of suspected and confirmed sylvatic cases demonstrates that active surveillance is functioning well in some areas.
  • Nevertheless, it is important to note the inherent difficulties in surveillance and laboratory confirmation capacities.
  • It remains possible that detection of a case could be delayed in some remote areas.
  • A strong and sustained surveillance effort is therefore more crucial than ever.
