Question

What effect do natural disasters have on the population?

Answer 1

Hint: Disaster epidemiology is the analysis of the effects of disasters on human populations, mostly through data collection and mathematical studies, with the goal of forecasting possible disaster impacts.

Complete answer:
Natural disasters may have a variety of effects on public wellbeing. Many incidents have the greatest effects on the people who are injured as a result of the catastrophe.

 In general, disasters including water (such as flooding, storm waves, and tsunamis) result in the highest number of deaths.

The number of fatalities in these incidents far outnumbers the number of nonfatal injuries. Earthquakes and incidents involving strong winds, on the other hand, are more likely to result in casualties than deaths.

 In the percentage of fatalities to nonfatal casualties, injury rates due to human-caused disasters are even more variable.

In the wake of a tragedy, health problems emerge as well. In most emergency cases, infectious disease outbreaks are not the most pressing problem in the near term.

The risk of outbreaks would not occur soon following an incident, but one or two weeks later, and only if there is significant population relocation and health care interruption.

The effect of human relocation is often the main concern in the wake of a catastrophe. Natural and man-made events often damage large quantities of land, such as homes and farmland.

From a health standpoint, the effects of providing little to no shelter (environmental exposure) and overcrowding of accessible shelters are the most pressing concerns. In the long run, there could be a mortality risk associated with the inability to properly feed the infected population.

Note: Another critical wellness problem that has both short- and long-term ramifications is the mental health effects of a catastrophe. Following global events, studies have shown that depression and post-traumatic stress disorder are more common.
