Hypothesis

What is the rate of discovery of new human virus species over time?

Conclusion

New human viruses are likely to continue being discovered, indicating that public health planning must account for these potential threats.

Supporting Evidence

  • The cumulative species discovery curve for human viruses shows a slow initial increase followed by a rapid rise.
  • The model predicts that 10 to 40 new virus species will be discovered by 2020.
  • The study found a correlation between the number of viruses discovered and the year, indicating ongoing discovery.

Takeaway

Scientists are finding more than two new human viruses every year, and they think there are many more still out there waiting to be discovered.

Methodology

The study used a cumulative species discovery curve and piecewise linear regression to analyze the rate of virus discovery.

Potential Biases

Potential bias due to reliance on published reports and the possibility of unreported viruses.

Limitations

The study does not account for variations in detection techniques and reporting over time.
