Common Diseases Associated With Floods

Introduction

Malaysia frequently experiences flooding, particularly during the monsoon season, which typically occurs from May to September and November to March.

Heavy rainfall, coupled with the country's tropical climate, often leads to flash floods, riverine floods, and urban flooding.

Flooding can lead to several waterborne and vector-borne diseases, primarily due to the contamination of water supplies and the conditions that promote the spread of pathogens.

 

Common Diseases

Here are some common diseases associated with flooding:

1. Dengue Fever

Transmitted by the Aedes mosquito, dengue outbreaks can spike after flooding, as stagnant water provides breeding grounds.

 

2. Leptospirosis

This bacterial infection is contracted through contact with water contaminated by the urine of infected animals, particularly during floods.

 

3. Cholera
A serious diarrhea disease caused by Vibrio cholerae, cholera can spread through contaminated water sources during floods.

 

4. Typhoid Fever

Caused by Salmonella typhi, this disease can occur when food and water become contaminated in flooded areas.

 

5. Gastroenteritis

Often caused by viruses or bacteria, gastroenteritis can spread through contaminated water and food during floods.

 

6. Hepatitis A

This viral liver infection spreads through contaminated food and water, which can be more common in flooded regions.

 

7. Skin Infections

Floodwaters can carry bacteria and fungi, leading to skin infections, especially in individuals with open wounds.

 

8. Malaria

While less common, flooding can create conditions favourable for mosquito breeding, potentially increasing malaria risk.

 

 

Conclusion

Flooding in Malaysia poses significant public health risks due to the potential for various diseases.

Effective public health measures, including clean water access, vector control, and community education, are crucial for mitigating these risks during and after flooding events.

Boosting immunity can indeed help the body better resist infections too, including those associated with flooding and other environmental stressors.
