Two conditions essential for being free of disease are Personal Hygiene and Clean Environment.

Explanation:
1. Personal Hygiene: Good hygiene practices, such as frequent hand washing, covering your mouth when coughing or sneezing, and keeping things clean, can help prevent the spread of disease-causing germs.

Good hygiene practices also reduce the risk of contracting infections and other diseases.

2. Clean environment: A clean environment is an essential condition for being free of disease. A dirty environment can be a breeding ground for disease-causing organisms, such as bacteria, viruses, and parasites.

Cleanliness helps to prevent the spread of disease by removing the sources of contamination and reducing exposure to harmful pathogens. Regular cleaning and disinfection of surfaces, proper waste disposal, and maintaining clean water sources are all important for creating a clean environment that supports good health.
