The IELTS Reading section can be challenging, but selecting relevant and timely topics can make studying both engaging and educational. One topic of increasing global importance is the relationship between urbanization and the spread of infectious diseases. This subject has appeared in various forms in past IELTS exams due to its contemporary relevance and depth. Given the rising rates of urbanization and the spread of global pandemics, this theme might reappear in future exams. Understanding this topic not only prepares you for IELTS but also enhances your awareness of critical global issues.
Reading Passage
The following is a medium-difficulty reading passage formatted to mirror the IELTS Reading section. Practice comprehending the passage and answering the questions that follow to gauge your readiness.
How Does Urbanization Influence the Spread of Infectious Diseases?
Urbanization, the process by which rural areas transform into urban areas, has significant impacts on societal dynamics, particularly public health. The rapid and often unplanned expansion of cities can lead to overcrowded living conditions, inadequate sanitation, and limited access to healthcare. These factors collectively enhance the risk of infectious disease transmission.
Historically, infectious diseases such as the plague have devastated densely populated areas. The reasons are multifaceted: high human density facilitates the rapid spread of pathogens, while poor sanitation and inadequate waste management further exacerbate the problem. Today, urbanization continues to play a crucial role in the epidemiology of infectious diseases.
Firstly, overcrowding in urban areas provides an ideal environment for pathogens to proliferate. Close contact between individuals in confined spaces, such as public transport systems, increases the likelihood of transmission of airborne diseases like tuberculosis and influenza.
Secondly, many rapidly urbanizing areas suffer from insufficient infrastructure. Inadequate water supply and waste disposal systems can lead to outbreaks of waterborne diseases like cholera and dysentery. Additionally, stagnant water in urban settings is a breeding ground for vectors such as mosquitoes, which spread diseases like malaria and dengue fever.
Thirdly, urbanization can strain healthcare systems. In many developing cities, the influx of residents pursuing better economic opportunities overwhelms healthcare facilities. This strain can result in delayed diagnoses and treatments, further enabling the spread of infectious diseases.
Lastly, the environmental changes associated with urbanization can alter the habitats of disease vectors. Deforestation and the creation of urban slums bring human populations into closer contact with animals, increasing the risk of zoonotic diseases—pathogens that jump from animals to humans. HIV, SARS, and COVID-19 are examples of zoonotic diseases exacerbated by urbanization.
In conclusion, while urbanization brings economic growth and development opportunities, it also poses significant challenges for managing infectious diseases. Addressing these challenges requires a multifaceted approach, including improving urban planning, investing in infrastructure, and strengthening healthcare systems.

Answers and Explanations
Multiple Choice
-
c. Decreased birth rates
- Explanation: The passage does not mention decreased birth rates as a consequence of urbanization.
-
b. Overcrowded public transport systems
- Explanation: The passage specifies that close contact between individuals in confined spaces like public transport systems facilitates the spread of airborne diseases.
True/False/Not Given
-
True
- Explanation: The passage mentions deforestation and urban slums bringing human populations into closer contact with animals, increasing the risk of zoonotic diseases.
-
False
- Explanation: The passage states that many rapidly urbanizing areas suffer from insufficient infrastructure, indicating that not all cities have good infrastructure.
Short-answer Questions
-
Malaria and Dengue fever
- Explanation: These diseases are mentioned as being transmitted by mosquitoes, which breed in stagnant water commonly found in urban areas.
-
The plague
- Explanation: The passage refers to the historical examples where the plague devastated densely populated areas.
Common Mistakes
Many students struggle with interpreting the exact wording of the questions and passages, leading to mistakes such as:
- Misidentifying information not explicitly stated in the text (e.g., assuming decreased birth rates as a consequence).
- Overlooking important connectors or qualifiers (e.g., “many,” “some”).
- Making assumptions based on prior knowledge rather than the passage content.
Vocabulary
- Urbanization (noun) [ˌɜːrbənaɪˈzeɪʃn]: the process by which cities grow or by which societies become more urban.
- Proliferate (verb) [prəˈlɪf.ə.reɪt]: to increase rapidly in number or amount.
- Vector (noun) [ˈvek.tər]: an organism, typically a biting insect or tick, that transmits a disease or parasite from one animal or plant to another.
- Zoonotic (adjective) [ˌzuː.ɒˈnɒ.tɪk]: (of a disease) able to be transmitted from animals to humans.
Grammar Points
Use of Passive Voice
In the sentence, “Overcrowded living conditions are exacerbated by inadequate sanitation,” passive voice emphasizes the conditions being affected more than the agents causing the effect. This is commonly used in academic writing to maintain objectivity.
Present Perfect Tense
The sentence, “Urbanization has influenced the spread of infectious diseases over the past decades,” uses the present perfect tense to indicate an action that began in the past and continues to the present.
Tips for a High IELTS Reading Score
- Skim and Scan: Quickly skim the passage to get the gist and scan for specific information related to the questions.
- Time Management: Allocate time wisely across passages, spending no more than 20 minutes per set of questions.
