of AFP cases
• Provinces are to ensure health workers are sensitized for improved detection, reporting and investigation
of suspected measles and AFP cases

Ebola Virus Disease Preparedness

• All provinces to strengthen EVD surveillance among all health care providers and raise commu-nity awareness
of EVD prevention
• Provide weekly reports in IDSR reports of active searches including zero reporting in at risk dis-tricts, 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 Cholera Hotspots

• Cholera hotspots to continue heightened surveillance and review of epidemiological trends to quickly detect
and respond to changes
• Continue to provide health education to sensitize communities and health workers on cholera pre-ventative
• WASH continue water monitoring and distribution of chlorine in identified at risk populations
