The intersection of health sciences and geography - IELTS Reading with Answers And Explanation

The Intersection of Health Sciences and Geography

A
AThanks to better sanitation and to the wider medical care people can now obtain, a great many of the illnesses that once troubled humankind have been wiped out; even so, particular health problems remain far commoner in some corners of the world than in others. Our planet is now more tightly interconnected than at any earlier point in history, with people constantly meeting through travel and settling ever nearer to one another. One upshot of this is that so-called super-viruses, along with other infections that no longer respond to the drugs meant to treat them, are cropping up with growing frequency.
B
BCircumstances of this kind are exactly where a discipline known as health geography proves its worth. Its importance keeps climbing in an era when illnesses such as measles are staging a comeback, breathing disorders continue to spread, and regions plagued by tropical infections are still hunting for more effective remedies. At its core, the field marries two bodies of knowledge: a command of geography, together with the techniques for analysing and interpreting geographical data, and the study of health, disease and medical care as practised across the globe. What this hybrid science sets out to do is devise remedies for health problems that are rooted in place. Human beings may never be wholly free of sickness, yet examining how geography shapes our health might one day allow some diseases to be stamped out and others headed off before they ever take hold. Grasping the reasons and the mechanisms behind illness lets us reshape the way we tackle the diseases tied to particular parts of the world.
C
CThe health worries facing any given community are frequently shaped by geography to a striking degree. Where a person happens to live, in other words, largely dictates the sorts of ailments they are exposed to, and these will differ from the ones threatening someone in another part of the world. Schistosomiasis offers perhaps the clearest illustration: the freshwater snails that pass this infection on to people flourish in the warm, sluggish waters typical of many tropical lowlands. Across arid highlands, by contrast, the disease is hardly ever encountered.
D
DIn certain nations the sway that geographical factors hold over people's health and well-being is unmistakable. Within sprawling cities the breeze is frequently too weak to sweep away the dense smog and pollution that leave residents suffering from asthma, damaged lungs, poor eyesight and a host of other complaints. Much of the blame lies with the sheer volume of traffic on the roads, compounded by furnaces that are fired with coal. And as several countries have industrialised at speed in recent years, expanses of woodland have been cleared to make room for the spread of big cities, which only makes the pollution harder to counter, since it removes the clean air that plants would otherwise produce.
E
EOne major branch of the discipline concerns itself with the geography of healthcare provision. Its practitioners look at how far, or how little, medical resources actually reach individuals and communities around the globe. Whether a country is wealthy or poor, a marked gap tends to separate the choices open to people of differing social class, income level and schooling. Those working in this branch try to gauge the standard of care on offer in a given place; reaching a doctor may be genuinely hard, for example, when a wide river lies between a settlement and the nearest hospital. Such specialists stand at the forefront of advising international bodies, local authorities and others on the policies they ought to adopt.
F
FA second strand, the geography of disease and ill health, looks at how often particular illnesses crop up in different corners of the world and lays that information over the region's geography, hunting for any link between the two. Specialists here also probe the conditions that might leave a given person or community more susceptible to a specific complaint than people living elsewhere. As a rule, those who work in this strand have trained as healthcare professionals and possess a working grasp of the basic epidemiology that governs how disease travels through a population.
G
GThe researchers in this second strand examine the ways in which human beings interact with their surroundings such that illness can result, asthma in heavily polluted places being one instance, and they set about devising a clear system for sorting illnesses, diseases and epidemics by whether their reach is local or global. Through charting how sicknesses spread, they try to pin down what lies behind a rise or a fall in particular illnesses, all with the aim of checking the further advance, or the return, of diseases among populations at risk.
H
HHealth geography may be a frequently neglected field, yet it answers an enormous need at the meeting point of geography and healthcare. Once we grasp the way our location shapes our health, wherever on the map we happen to be, we become far better placed to treat disease, to ward off illness, and to keep people well and out of harm.
