The IELTS Reading section is a crucial component of the test, assessing your ability to understand complex texts and extract specific information. Today, we’ll focus on a topic that has gained significant attention in recent years: “Urbanization’s role in spreading zoonotic diseases.” This subject has appeared in various forms in past IELTS exams and remains highly relevant given the ongoing global health challenges. Let’s explore this topic through a practice reading passage and questions, followed by in-depth analysis and tips to boost your IELTS Reading performance.
Practice Reading Passage
Urbanization and the Spread of Zoonotic Diseases
Urbanization, the process of human population shift from rural to urban areas, has been a defining trend of the 21st century. While it has brought about numerous economic and social benefits, it has also contributed to the emergence and spread of zoonotic diseases – those that can be transmitted between animals and humans. This phenomenon has become a significant concern for public health officials and urban planners alike.
The rapid expansion of urban areas often encroaches upon natural habitats, bringing humans into closer contact with wildlife. This proximity increases the likelihood of zoonotic pathogens jumping from animals to humans. For instance, deforestation to make way for urban development can displace bats, known reservoirs for viruses like Ebola and SARS-CoV. These animals may then seek shelter in urban or suburban areas, potentially exposing humans to new pathogens.
Moreover, urban environments can create ideal conditions for disease vectors such as mosquitoes and rats to thrive. Poor sanitation, inadequate waste management, and standing water in densely populated areas provide breeding grounds for these vectors. Aedes aegypti mosquitoes, carriers of dengue fever and Zika virus, have adapted particularly well to urban settings, leading to increased outbreaks in cities worldwide.
The concentration of human populations in cities also facilitates the rapid spread of diseases once they emerge. High-density living, shared public spaces, and extensive public transportation networks can accelerate transmission rates. This was evidenced during the COVID-19 pandemic, where urban centers became hotspots for virus spread.
However, urbanization is not solely a risk factor. Cities often have better healthcare infrastructure and surveillance systems, which can lead to earlier detection and more effective responses to disease outbreaks. The challenge lies in balancing urban development with measures to mitigate the risk of zoonotic disease spread.
Experts suggest several strategies to address this issue. Implementing “One Health” approaches that recognize the interconnection between human, animal, and environmental health is crucial. This involves collaborative efforts between urban planners, public health officials, and ecologists to design cities that minimize human-wildlife conflict and promote overall ecosystem health.
Improving urban sanitation and waste management systems can reduce vector populations and limit human exposure to potential pathogens. Additionally, preserving green spaces within and around cities can maintain biodiversity and natural buffer zones between human settlements and wildlife habitats.
Education and public awareness campaigns are also vital. Informing urban residents about the risks of zoonotic diseases and promoting responsible behavior, such as proper food handling and avoiding contact with wildlife, can significantly reduce transmission risks.
As urbanization continues to shape our world, understanding and mitigating its role in the spread of zoonotic diseases will be crucial for safeguarding public health. By adopting holistic, sustainable urban development practices, we can create cities that not only accommodate growing populations but also coexist harmoniously with the natural world, reducing the risk of future pandemics.

Grammar Spotlight
Passive Voice in Scientific Writing:
The passage uses passive voice frequently, which is common in scientific and academic writing. For example:
“This phenomenon has become a significant concern for public health officials and urban planners alike.”
Passive voice is used to emphasize the action or result rather than the doer. It’s particularly useful when the doer is unknown, unimportant, or obvious from the context.
Structure: Subject + to be (conjugated) + past participle
Example: “Zoonotic diseases are transmitted between animals and humans.”
Active equivalent: “Animals and humans transmit zoonotic diseases between each other.”
