Every monsoon, Kerala experiences an increase in illnesses caused by contaminated water. Heavy rainfall, flooding and overflowing drains may contaminate drinking water sources with harmful bacteria, viruses and parasites.
Most water borne diseases are preventable through safe drinking water, proper sanitation and good personal hygiene. Awareness and early action play an important role in protecting families during the rainy season.
What are water borne diseases
Water borne diseases are infections that spread through contaminated drinking water or food prepared using contaminated water. They commonly affect the digestive system and may spread rapidly within communities.
The risk increases during the monsoon because heavy rains may contaminate wells, storage tanks and public water supplies.
Common water borne diseases during monsoon
Common illnesses include acute diarrhea, cholera, typhoid fever, hepatitis A, shigellosis and other intestinal infections.
These infections are usually caused by bacteria, viruses or parasites entering the body through contaminated food or drinking water.
How these diseases spread
The microorganisms spread when drinking water becomes contaminated with sewage or when food is prepared without proper hygiene.
Poor hand washing, unsafe food handling and inadequate sanitation further increase the risk of transmission.
Common symptoms
Symptoms may include diarrhea, vomiting, abdominal pain, fever, nausea, weakness and loss of appetite.
Some infections may also cause jaundice, bloody diarrhea or severe dehydration depending on the organism involved.
Importance of safe drinking water
Drink only clean and safe water. Boiling drinking water adequately before use is one of the simplest and most effective ways to reduce the risk of many water borne infections.
Water storage containers should be kept clean and covered to prevent contamination.
Maintain proper food hygiene
Consume freshly prepared food whenever possible. Wash fruits and vegetables thoroughly using safe water before consumption.
Avoid eating food from unhygienic sources and ensure cooked food is stored safely to prevent contamination.
Personal hygiene protects the family
Wash hands thoroughly with soap before eating, before preparing food and after using the toilet.
Teaching children proper hand hygiene is one of the most effective ways to reduce the spread of intestinal infections.
Prevent dehydration during illness
Vomiting and diarrhea may rapidly lead to dehydration, especially in young children and older adults.
Adequate fluid intake and early medical evaluation are important if symptoms become severe or prolonged.
When should medical advice be sought
Medical evaluation should be sought if diarrhea is severe, contains blood, persists for several days or is associated with high fever, repeated vomiting or signs of dehydration.
Infants, elderly individuals, pregnant women and people with chronic illnesses should receive prompt medical attention if symptoms develop.
Protecting your family throughout the monsoon
Simple daily habits such as drinking safe water, maintaining food hygiene and practicing proper hand washing can significantly reduce the risk of water borne diseases.
Community awareness and timely medical evaluation remain essential for preventing outbreaks during the rainy season.
