HOUSE TO HOUSE MOBILIZATION FOR SUCCESSFUL MEASLES SIAs
HOUSE TO HOUSE MOBILIZATION FOR SUCCESSFUL MEASLES SIAs: SITREP AFTER FIVE YEARS IN AFRICA Bob Davis Measles/Health Delegate American Red Cross
WHOM DO WE HAVE TO REACH TO STOP MEASLES TRANSMISSION? § § § Ethno-linguistic minorities and slum dwellers Marginalized and ‘floating’ populations, both urban, peri-urban, and rural In a nutshell: Those who don’t watch CNN, don’t listen to the BBC, and don’t read the New York Times • Solution, for both polio and measles: next slide Photo, Prof. Stanley Foster 1
THE HOUSE TO HOUSE STRATEGY § § For GPEI, OPV SIA policy since 2001 PAHO policy in Latin America for measles SIAs: H 2 H mobilization in campaigns which vaccinated from fixed posts and fixed mobile posts H 2 H mobilization a best practice, UN supported measles SIA, Ethiopia, 2010 Used in Red Cross supported campaigns in 10 African countries: Benin, Burundi, C. A. R. , Kenya, Mali, Mozambique, Namibia, Senegal, Tanzania, Uganda 2
COMMUNITY MONITORING AS PART OF H 2 H MOBILIZATION Wherever possible, line list the 9 - to 59 -month-olds in the week before the campaign, using RC volunteers, then trace defaulters after Day 1 of the campaign to bring them in from home. Example from Tanzania: 3
HOUSE TO HOUSE MOBILIZATION (cont. ) § § § Does H 2 H mobilization produce better results in measles SIAs? Probably: Traditional mass media approaches may miss the least readily accessible populations, even in urban areas. Herd immunity is more easily achievable when we systematically reach populations who lack, e. g. , radio and TV. Data from 8 countries tend to support this hypothesis. 4

H 2 H EVALUATED AS BEST PRACTICE, BENIN CAMPAIGN, 2011 CRITERIA Effectiveness Efficiency Relevance Feasibility Reproducibility Participation of the partners ANALYSIS BY CRITERION - Strong mobilization of the parents of children targeted at the time of the passage of the teams in the villages CONCLUSION Satisfactory - Better knowledge of the populations of the campaign schedule, of the strategy of progression of the teams and of the campaign’s target disease - Reduction of the number of people reluctant to vaccinate Satisfactory - Improvement of the vaccine coverage in the localities benefiting from the support of mobilizers - Facilitate the acceptance of vaccination by the populations in the urban zones - Valid for all the vaccination campaigns even the JNV polio - Implementation in the country’s 3 largest cities and in 12 other communes of the country - Activities mainly undertaken by the volunteers of the Red Cross, the Community and members of the Church of Jesus Christ of Latter Day Saints Satisfactory
WHAT THE DATA SHOWS § § § Large chunks of the urban population, and even of many rural populations, are accessible through mass media approaches. However, we are unlikely to achieve herd immunity in campaigns without house to house mobilization. In addition to campaigns, intercampaign house canvassing, 1 ½ years after the SIA, is a promising possibility to reduce the risk of outbreaks between campaigns.
METHODS FOR EVALUATING COMPARATIVE PERFORMANCE OF H 2 H AND CONVENTIONAL APPROACHES BEST OF ALL POSSIBLE WORLDS PLANET EARTH § 30 cluster surveys, intervention and nonintervention areas §Yes; §Admin §Yes, §Spot coverage estimates surveys at vaccination sites to ascertain mothers’ source of info. Cheap and easy; permits assessment of comparative role of H 2 H and other info sources so far, only in mainland Tanzania, with results ranging from 72 to 100 percent in areas with house visiting. but check your denominators. With data retention and/or recording errors, check your numerators as well. §Spot surveys at vaccination sites to ascertain mothers’ source of info. Cheap and easy; permits assessment of comparative role of H 2 Hand other info sources §Compare to IM data where available.
WHY WE NEED MORE SPOT SURVEYS § § § Cluster coverage surveys, with more scientific rigor, are not always done, and rarely permit comparison between areas with and without house visiting. Admin coverage data are based on high side population figures (Eritrea) or low side population figures (Uganda). >>100% coverage = high degree of flakiness; true of ½ of all districts in Uganda’s 2012 measles SIA. Data retention by health workers (Senegal, Kampala) makes it impossible to calculate SIA admin coverage.
COSTING OF HOUSE TO HOUSE MOBILIZATION § § Vitamin m, the indispensable micronutrient Single partner funding by American Red Cross is not a viable option for H 2 H mobilization to go to scale.

CONCLUSIONS § § § In areas with H 2 H mobilization, measles SIA cost per child rises from ~$1 to ~$1. 32 or more. We need to be selective in choosing areas for H 2 H. Selection criteria used by American Red Cross and, in some countries, UNICEF: § Underserved populations, especially slums § Areas with low coverage and/or high cases based on case based surveillance § Geographically remote areas
CONCLUSIONS (CONT. ) § § Some countries (Kenya, Burkina Faso) have widespread viral seeding from town to country. There, it may be necessary there to target whole cities, not just slums. In some settings, the dollar goes farther in urban H 2 H mobilization (Tanzania vs. Namibia). Where funding is short, first priority goes to underserved urban and periurban areas.
THE MAGIC FORMULA § § There is no magic formula for targeting areas to cover through H 2 H. Where viral seeding is well documented, target the source of the viral seeding. Where coverage data are reliable, target areas with low coverage. Where case based surveillance is good, target areas with cases (Burundi: 4/17 regions were home to 29/30 confirmed measles cases).
URBAN PARTICULARITIES § § § Weekend SIA start is preferable; no traffic jams to tie up logistics; pulpit announcements on Fridays and Sundays Multilingual house visitors and vaccinators are needed – Dakar, Nairobi, for example. Mapping of neighborhoods with many migrants and floating populations, for special emphasis by gov’t, RC and other partners
H 2 H CANVASSING FOR ROUTINE IMMUNIZATION? § § § American Red Cross & partners need to consult on how best to apply lessons learned from SIAs to routine immunization. A network of volunteers already exists to sensitize the community. Possible modalities: birth registration and follow-up; periodic village canvasses; linkages to health facilities for defaulter follow-up
SO WHERE IS H 2 H GOING? § § § Depends on decisions made by the MRI, as by the GPEI in 2001, when the polio initiative opted for H 2 H OPV SIAs. If H 2 H mobilization goes global with measles, as with polio, then more resources and partners will be needed. You can’t go global on a shoestring, and you can’t do it with 1 or 2 partners, as at present. Decision whether to go global with H 2 H should predate any WHA resolution. No 1988 -2001 gap as with GPEI, SVP!
