Behaviour change is difficult anywhere in the world – which is why talking to communities about hygiene isn't always easy. It often involves challenging age-old taboos, for example those surrounding menstrual hygiene, and asking people to change habits involving handwashing, eating and keeping clean that they've had for generations. That’s why we don't have a one-size-fits-all approach to hygiene. Instead, we work with partner organisations, members of the community and schools, supporting them to keep clean and healthy so they can spread the word with their friends, family and communities, and ensure the arrival of taps and toilets means the start of lasting change. The blue hand game, Bangladesh Diseases such as diarrhoea spread fast in schools, but explaining how germs travel can be tricky. Our blue hand game starts with a football covered in blue powder, and ends with a better understanding of how easily germs can spread to hands and faces, underlining the importance of washing your hands before eating.

The children loved it and the response was overwhelmingly positive – a vital first step in developing good hygiene practices in time for new taps and toilets being installed.

We've also been spreading the word about better hygiene through posters like this one, as well as using plays, music and songs to show the benefits of keeping clean and healthy.

Our menstrual hygiene education groups not only supported local girls and women to take control of their monthly bleed, but also motivated the men in the village to support them – including through menstrual hygiene card games like this one.

Their board teaches them the dangers of going to the toilet in the bush and eating fruit without washing it first, and shows how boiling their drinking water and looking after their water source can save them from diseases.
