Lack of hygiene and sanitation can lead to health issues and spread of diseases. Poor hygiene and sanitation can be caused by lack of access to clean water, lack of education on proper hygiene practices, inadequate sanitation infrastructure, and a lack of resources to maintain proper sanitation. People living in poverty often have difficulty accessing clean water, proper toilet facilities, and soap for washing their hands. Improving access to clean water, sanitation facilities, and hygiene education can reduce the spread of diseases and improve overall health.
