Transcript

Everyone is susceptible to  infectious diseases of some kind. But not everyone is equally likely  to be the victim of an outbreak. It’s vital to know where outbreaks  of infectious diseases tend to happen and who is most at risk of  being infected and falling ill, so we can target our strategies to prevent  outbreaks and help those most affected by...

Questions & Answers

Q: How do social factors like population growth and urbanization influence the likelihood of disease outbreaks?

Population growth leads to increased interactions between people and animals, increasing the risk of zoonotic spillover. Urbanization can create overcrowded conditions and inadequate infrastructure, facilitating disease spread.

Q: What role does globalization play in shaping the economic factors that affect outbreaks?

Globalization through trade and movement of people influences the spread of diseases, with disparities in access to resources and healthcare affecting susceptibility to outbreaks.

Q: How do environmental conditions like deforestation contribute to the risk of disease outbreaks?

Deforestation displaces natural habitats of animals, leading to increased contact between wildlife and humans. This can result in outbreaks of diseases like Hantavirus due to the proximity of infected rodents to human populations.

Q: In what ways do conflicts impact the likelihood of disease outbreaks among refugee populations?

Conflict disrupts infrastructure, leading to unsanitary conditions that facilitate disease spread. Refugee camps, often overcrowded and lacking resources, become hotbeds for outbreaks like the Hepatitis A outbreak in a refugee camp in Lebanon during the Syrian war.

Summary & Key Takeaways

• Infectious disease outbreaks are influenced by social factors like population growth, urbanization, and international travel.

• Economic factors such as globalization, trade, and access to resources impact susceptibility to outbreaks.

• Environmental conditions like deforestation, extreme weather events, and conflicts contribute to the spread of diseases.
