Implication

Randomized trial estimates the reproductive number and infection dynamics in tuberculosis, suggesting implications for control measures.

Key Points

This research aims to develop a mathematical model of tuberculosis transmission dynamics, focusing on the delay from latent infection to active disease.
Constructed a model using epidemiological data on tuberculosis from the United States.
Calculated a fractional rate of change in active tuberculosis incidence from 1930 to 1995.
Derived estimates for the effective reproductive number and cumulative transmission.
Estimated reproductive number (R) at approximately 0.55 and cumulative transmission at about 1.2 for a case rate of -4% per year.
Estimated 80,000 new latent infections annually in the U.S. and 5% prevalence of latent infections.
Predicted risk of activation varies by age, decreasing rapidly in the first 10 years and remaining relatively constant from 10 to 40 years.
