Measles outbreak response : Rapid Response Team Line list of suspected measles cases with follow up the contacts Detecting the index case Lab: Sampling ( Blood sample and throat swab) Map for area with cases distribution Control measures (case isolation, treatment, Health education and outreach activities) immediate reporting of newly cases Epidemic curve Report Documentation
14
Outbreak response Emergency measles outbreak response: – Vaccination around the case – April- May 2013: Measles/Polio/vitamin A campaign at Zaatari and EJC camps (covering 71,000 individuals up to 30 y). – June-July 2013: out of camp Measles/Vitamin A campaign in 2 Governorates bordering Syria and Iraq (covering 622,000 children up to 15 y). – November 2013: Measles/Rubella/Polio/Vitamin A campaign is going on:
15
Campaign results – administrative data *Note: Higher reported coverage among the Syrian population may be due to less accurate population target estimates - population change due to their mobility (i.e. some may be registered in Amman, but reside in Irbid or Mafraq), or they may be un-registered.
16
Results of PCES Overall 898 houses were visited Data from one child per age group were used in the analysis 1,669 children – Irbid (819 children) – Mafraq (850 children)
17
PCES – Nationality and Age Group * In Irbid, coverage was significantly lower among children 10–14 years of age than in children 6–59 months or 5–9 years Coverage among Syrian children was lower compared to Jordanian children, but the difference was not statistically significant.
18
MR-P Campaign / 2-21 Nov.2013 MR Age group targeted = 6 M – 20 years OPV Age group targeted = 0 – 59 M Vit.A Age group targeted = 6 M – 59 M Campaign strategy : - through fixed teams at health centers - outreach teams in the Universities, schools, NGOs,Malls.. Etc. - mobile teams to hard to reach and mobile populations
19
Due to polio situation in Syria we have now competing priorities regarding the measles & Polio which implicate to combine the improvement of AFP & measles surveillance and all other activities related
20
Lessons learned - 1 Frequent advocacy meetings and coordination among all partners allowed for good communication and improvements throughout the campaign Close collaboration with UNHCR and NGOs resulted in high coverage among Syrians during the campaign – Specialized strategies for reaching Syrian children needed Intensified supervision structure allowed for careful monitoring and correction of any issues that arose – Also allowed for immediate action to be taken by the campaign teams Daily supervisory tour plans and checklists provided transparency and accountability
21
Lessons learned - 2 The Measles Control Rooms were critical to the success of the campaign – Managed vaccine distribution – Daily contact with the supervisors – Identified problems in the field and took immediate action
22
Lessons learned - 3 RCA is an important tool to find pockets of missed children and guide social mobilization efforts throughout the campaign
23
Challenges Intensifying measles rubella surveillance ( combined with AFP surveillance,surveillance officers for AFP and Measles –Rubella surveillance. Negative media ( communication group ) for preparing bilingual messages ) Reaching the older age groups of universities and schools students( meetings with students unions leaders, sending messages through the SMS, through media youth radios..) Competing priorities ( combining both activities for AFP & measles ) Reaching the un registered Syrians ( through the IOM and other NGOs dealing with Syrian refugees ).
