About Cholera
Cholera is an infectious disease caused by the bacterium Vibrio cholerae. It spreads through contaminated food and water. Symptoms include severe watery diarrhoea, vomiting, and dehydration. If untreated, cholera can lead to death within hours. However, proper hydration can prevent fatalities.
Causes of Cholera
The primary source of cholera is contaminated water supplies. Poor sanitation and hygiene practices exacerbate the risk. Common sources include:
- Polluted well water
- Foods from street vendors
- Raw vegetables grown using contaminated water
- Contaminated seafood
Transmission can occur even if an infected person shows no symptoms.
Symptoms and Stages of Cholera
Symptoms manifest between a few hours to five days after infection. They can range from mild to severe. Key symptoms include:
- Severe watery diarrhoea
- Vomiting
- Dehydration signs
Cholera progresses through three stages:
- Evacuation Stage: Lasts 3-12 hours, with symptoms like cramps and thirst.
- Collapse Stage: Severe dehydration occurs, leading to potential loss of consciousness.
- Recovery Stage: Symptoms may improve, but the risk of other infections remains.
Public Health Response
Local authorities have taken immediate action. The Jajpur district administration cancelled holidays and banned community feasts to curb further spread. Health officials are monitoring the situation closely and raising awareness in local communities. The Chief Secretary of Odisha has directed neighbouring districts to remain vigilant against waterborne diseases. The Indian Council of Medical Research and the World Health Organization are assisting in containment efforts.
Global Context of Cholera
Cholera is a global health issue, particularly in regions with poor sanitation. The World Health Organization estimates 1.3 to 4 million cholera cases annually. Despite being rare in developed countries, outbreaks continue to pose a threat in parts of Africa, South Asia, and Latin America.
Preventive Measures
Preventing cholera involves improving sanitation and hygiene practices. Key measures include:
- Access to clean drinking water
- Proper food handling and preparation
- Community education on hygiene
These steps are essential to mitigate cholera outbreaks and protect public health.
