Questions & Answers

Q: What are some factors that contribute to the emergence of diseases?

Factors such as increasing world population, globalization, changing climates, and encroachment into animal habitats contribute to the emergence of diseases.

Q: How does genomic science help in understanding the spread of variants within populations?

Genomic science analyzes the DNA of populations and can trace the spread of variants that enhance survival and reproduction, providing clues to human adaptation.

Q: Why is the LARGE gene important in the context of Lassa fever?

The LARGE gene modifies the receptor for Lassa virus, allowing the virus to enter cells. Its strong adaptation in a Nigerian population suggests a connection to the disease.

Q: What is the significance of the discovery of antibodies to Lassa virus in the population?

The discovery of antibodies in over 20% of the population suggests that Lassa fever has been circulating widely for many years, challenging the notion of it being an emerging disease.

Summary & Key Takeaways

• Emerging diseases such as Marburg virus, Lassa virus, Ebola, and HIV have become prevalent due to factors like increasing population, globalization, and encroachment into animal habitats.

• Genomic science has the power to analyze the DNA of populations and trace the spread of variants that enhance survival and reproduction.

• One gene called LARGE, found in a Nigerian population, was discovered to modify the receptor for Lassa virus, suggesting a strong adaptation to the virus.
