0.0% CFR
EVENT DESCRIPTION
From week 1 2021 (ending 10 January 2021) through week 1
2022 (ending 9 January 2022) a total of 3 362 Acute Flaccid
Paralysis (AFP) cases were reported among which, 19 cases
were confirmed to be circulating vaccine-derived poliovirus type
2 (cVDPV2) from four provinces (Sud Ubangi, Mongala, Nord
Ubangi and Maniema) of the Democratic Republic of the Congo.
No death was reported among these cVDPV2 cases. Majority
of the cases have been reported from Maniema province (9
cases, 47.4%) followed by Sud Ubangi with 5 cases (26.3%),
and Mongala with 4 cases (21.0%). An additional 2 environment
samples from Maniema province tested positive for cVDPV2.
During the period, week 1 through week 51 (ending 26 December
2021), a total of 10 937 polio alerts were received, of which
10 921 were investigated (99.8%) including 10 762 that were
investigated within 48 hours (98.5%). Specifically, in week 51, a
total of 152 alerts were received, of which 143 were investigated
within 48 hours (94.1%).
Since 2017, the Democratic Republic of the Congo has reported
a total of 234 (1.5%) cVDPV2 cases of 15 371 Acute Flaccid
Paralysis (AFP) cases reported. Three (3) environmental samples
tested positive for cVDPV2 in the same period. The country
experienced 12 cVDPV2 outbreaks reported in 65 health districts
across 16 provinces.
To date, the cVDPV2 outbreak is still active is the provinces of
Kasai, Sankuru, Haut-Lomami, and Maniema.
PUBLIC HEATH ACTIONS
The national polio integrated technical team has conducted
field supervisions to the affected provinces
The preparations for the 2021 polio response activities
review including polio data management is ongoing
Field teams are conducting active polio case search and
supportive integrated supervisions to the affected health
districts
The preparations for deployment of technical teams (national
consultants) to the affected health districts have started
The polio outbreak risk assessment in Maniema province has
been finalized
SITUATION INTERPRETATION
Although the Democratic Republic of the Congo has been certified
as a “polio-free country” by the WHO since November 2015, the
country remains among high-risk countries for cVDP2 outbreaks.
Effort should be maintained especially for enhanced surveillance
and response to facilitate early detection and stop occurrence of
new outbreaks.
PROPOSED ACTIONS
The required resources should be mobilized to facilitate the
country achieve its national and Global polio eradication
objectives as quick as possible.
Specific response strategies are required for hard-to-reach
areas in order to eliminate the chain of transmission and
avoid new outbreaks.
