A systematic review of 70 studies found that local approaches are effective in increasing handwashing rates in low- and middle-income countries, and social marketing campaigns are less effective. Regarding the promotion of handwashing in schools, we can cite the example of &quot; the &quot;Three Star Approach&quot; from UNICEF, which encourages schools to take simple and inexpensive steps to ensure that students wash their hands with soap, while observing other hygiene rules.
Uchunguzi wa utaratibu wa tafiti 70 ulipata kuwa mbinu zinazohusisha jamii hufaa katika kuongeza kuosha kwa mikono katika LMIC, huku kampeni za kuhimiza jamii kubadilisha tabia zikifaa kwa kiwango cha chini.Mfano moja wa ukuzaji wa kuosha mikono katika shule ni &quot;Mbinu ya Nyota Tatu&quot; ya UNICEF inayohimiza shule kuchukua hatua rahisi, zenye gharama ya chini ili kuhakikisha kuwa wanafunzi wanaosha mikono yao kwa sabuni, kati ya mahitaji mengine ya usafi.
