Epidemics after disaster are caused by all except –
**Core Concept**
In the aftermath of a disaster, the risk of epidemics increases due to compromised water and sanitation systems, displacement of people, and damage to healthcare infrastructure. This creates an environment conducive to the spread of infectious diseases.
**Why the Correct Answer is Right**
The correct answer is related to the concept of "secondary disasters" that can occur after a primary disaster, such as an earthquake or hurricane. Secondary disasters can include outbreaks of infectious diseases, which are often caused by the displacement of people, contamination of water sources, and inadequate waste management. These factors can lead to the spread of diseases such as cholera, typhoid, and dysentery.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is a correct explanation for the spread of epidemics after a disaster. Displacement of people can lead to overcrowding and poor living conditions, making it easier for diseases to spread.
**Option B:** This option is incorrect because it is a correct explanation for the spread of epidemics after a disaster. Contamination of water sources can lead to the spread of waterborne diseases such as cholera and typhoid.
**Option C:** This option is incorrect because it is a correct explanation for the spread of epidemics after a disaster. Inadequate waste management can lead to the spread of diseases such as dysentery and typhoid.
**Clinical Pearl / High-Yield Fact**
In the aftermath of a disaster, it is essential to prioritize the provision of safe water, sanitation, and healthcare services to prevent the spread of epidemics. The World Health Organization (WHO) recommends a comprehensive approach to disaster response, including the deployment of emergency medical teams and the provision of essential medicines and medical supplies.
**Correct Answer: D.**
