All provinces are further encouraged to strengthen AFP surveillance using available technological tools and geo code all cases detected.
The national annualized Non Polio AFP detection rate has increased to 4 cases /100,000 of children detected under 15 years for provinces.
Note all AFP cases are immediately notifiable and require immediate investigation with new case investigation forms.
All districts are expected to conduct health facilities integrated supervisory active searches at priority sites as per recommended schedule.
Provinces to ensure silent districts not reporting AFP/measles cases are supported for active surveillance of AFP cases.
Ebola Virus Disease Preparedness
All provinces to strengthen EVD surveillance among all health care providers and raise community awareness of EVD prevention.
Provide weekly reports in IDSR reports of active searches including zero reporting in at risk districts, including ports of entry.
Ensure epidemic preparedness measures for detecting cases, sample testing/transportation and managing cases are effected.
All border districts to strengthen point of entry EVD screening including facilitation of cross boarder monitoring and reporting of suspected EVD cases.
Heightened Surveillance in COVID– 19 High Risk Districts
Surveillance (including Event Based Surveillance) is being actively conducted at POEs, health facilities, and sentinel sites.
Screening facilities have been set up at POEs; additionally, screening is being done at the dry port in Makeni for all buses coming in from outside the country.
