Sewage contains micro-organisms such as bacteria, viruses, fungi, and parasites. These can be particularly active in summer. Exposure to equipment or material contaminated by sewage can cause
• Gastroenteritis (stomach cramps, abdominal pain, diarrhea, vomiting)
• Hepatitis (inflammation of the liver, jaundice)
• Occupational asthma (breathlessness, tight chest, wheezing)
• Infection of eyes and skin.
