We designed the WASHmobile mobile health (mHealth) program for high risk populations for diarrhoea. In our previous randomised controlled trials in the Democratic Republic of the Congo (DRC) (PICHA7) and Bangladesh (CHoBI7), WASHmobile delivery to diarrhoea patient households through a healthcare facility visit and mobile messages from a doctor significantly reduced diarrhoea, cholera, and improved child growth. Building on this, we adapted WASHmobile for large scale implementation through a mHealth and e\u2010voucher program for diarrhoea outbreak areas. A pilot program evaluation of this approach was conducted in DRC health areas with ongoing diarrhoea outbreaks among 2022 participants. Voice and SMS messages from a doctor were sent to those within 500\u2009m of diarrhoea patients stating there was a diarrhoea outbreak nearby and emphasising the importance of treating and safely storing household drinking water and handwashing with soap for the next 7\u2010day high\u2010risk period. The SMS messages contained an e\u2010voucher to redeem for free chlorine tablets at a pharmacy or shop. Unannounced spot checks assessed WASH behaviours 7 days after program initiation. Fifty\u2010seven percent of WASHmobile households redeemed e\u2010vouchers. Compared to control, WASHmobile households redeeming e\u2010vouchers had higher stored drinking water with free chlorine concentrations &gt;\u20090.2\u2009mg\/L (Odds Ratio: 6.93, [95% Confidence Interval: 1.76, 27.24]) (64% [WASHmobile] vs. 20% [control]), higher stored drinking water completely covered (4.55 [2.68, 7.70]) (73% vs. 38%), and higher presence of a cleansing agent within 10 steps of latrine and cooking areas (latrine: 3.64 [1.47, 9.02] [70% vs. 39%] and cooking: 2.50 [1.31, 4.77] [70% vs. 49%]). The WASHmobile PICHA7 mHealth and e\u2010voucher program significantly increased water treatment, safe water storage and hygiene behaviours in diarrhoea outbreak areas in DRC.<\/jats:p>","DOI":"10.1111\/tmi.70109","type":"journal-article","created":{"date-parts":[[2026,3,10]],"date-time":"2026-03-10T23:23:25Z","timestamp":1773185005000},"page":"716-723","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Program Evaluation of the\n                    <scp>WASHmobile PICHA7<\/scp>\n                    Mobile Health and Chlorine E\u2010Voucher Program in the Democratic Republic of the Congo"],"prefix":"10.1111","volume":"31","author":[{"given":"Christine Marie","family":"George","sequence":"first","affiliation":[{"name":"Department of International Health, Program of Global Disease Epidemiology and Control Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean\u2010Claude","family":"Bisimwa","sequence":"additional","affiliation":[{"name":"Center for Tropical Diseases &amp; Global Health Universit\u00e9 Catholique de Bukavu  Bukavu Democratic Republic of the Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelly","family":"Endres","sequence":"additional","affiliation":[{"name":"Department of International Health, Program of Global Disease Epidemiology and Control Johns Hopkins Bloomberg School of Public Health  Baltimore Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin","family":"Bengehya","sequence":"additional","affiliation":[{"name":"Bureau de L'information Sanitaire, Surveillance Epid\u00e9miologique et Recherche Scientifique, Division Provinciale de la Sant\u00e9 Sud\u2010Kivu, Minist\u00e8re de la Sant\u00e9  Bukavu Democratic Republic of the Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean\u2010Claude","family":"Kulondwa","sequence":"additional","affiliation":[{"name":"Bureau de l'Hygi\u00e8ne et Salubrit\u00e9 Publique, Division Provinciale de la Sant\u00e9 Sud\u2010Kivu, Minist\u00e8re de la Sant\u00e9  Bukavu Democratic\u00a0Republic\u00a0of\u00a0the\u00a0Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raissa","family":"Boroto","sequence":"additional","affiliation":[{"name":"Center for Tropical Diseases &amp; Global Health Universit\u00e9 Catholique de Bukavu  Bukavu Democratic Republic of the Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ghislain","family":"Maheshe","sequence":"additional","affiliation":[{"name":"Faculty of Medicine Universit\u00e9 Catholique de Bukavu  Bukavu Democratic Republic of the Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cirhuza","family":"Cikomola","sequence":"additional","affiliation":[{"name":"Center for Tropical Diseases &amp; Global Health Universit\u00e9 Catholique de Bukavu  Bukavu Democratic Republic of the Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Presence","family":"Sanvura","sequence":"additional","affiliation":[{"name":"Center for Tropical Diseases &amp; Global Health Universit\u00e9 Catholique de Bukavu  Bukavu Democratic Republic of the Congo"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,3,10]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(18)30310-4"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(23)00458-0"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(17)30276-1"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/jn\/137.11.2464"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.2006.74.475"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/advances\/nmy101"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(02)07744-9"},{"key":"e_1_2_10_9_1","unstructured":"World Health Organization \u201cCholera in the WHO African Region: Weekly Regional Cholera Bulletin \u201d2024 https:\/\/www.afro.who.int\/health\u2010topics\/disease\u2010outbreaks\/cholera\u2010who\u2010african\u2010region#:~:text=As%20of%2031%20July%202024 (4%20375)%20deaths%20reported."},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1617218114"},{"issue":"6","key":"e_1_2_10_11_1","first-page":"2134","article-title":"Cholera Cases Cluster in Time and Space in Matlab, Bangladesh: Implications for Targeted Preventive Interventions","volume":"45","author":"Debes A.
