Well I say not just mud but there is water logging and diseases too which come out of rain.
Some precautions are necessary to keep oneself safe and health from monsoon related diseases
The diseases associated with monsoon are malaria, jaundice, gastro intestinal infections like typhoid and cholera. Apart from these, viral infections like cold and cough also make their presence felt.
Pollution of drinking water during monsoon is very common. It is very necessary to drink clean and pure water when water borne monsoon diseases like diarrhea and gastro intestinal infections threaten us. Drinking boiled water at home is strongly recommended to tap water. Prefer mineral water of government certified companies when you are away from home.
Walking in dirty water during rainy season leads to numerous fungal infections which affect toes and nails. Diabetic patients have to take a special care about their feet. Always keep your feet dry and clean. Avoid walking in dirty water. Keep your shoes, socks and raincoats dry and clean.

• Make sure that you cover the food, vegetables and fruits all the time, to protect them from flies.
• Avoid eating outside as much as possible especially roadside stalls due to hygiene concerns.
• Do not eat stale food. This pointer is applicable in all seasons.
• Make sure that you close water and mud pools on the road in your area or even water containers as openings like these lead to breeding of mosquitoes.
