On the basic reproduction number $R_0$ in sexual activity models for HIV/AIDS epidemics: Example from Yunnan, China

Mathematical Biosciences and Engineering, 2007
Heterogeneity in sexual behavior is known to play an important role in the spread of HIV. In 1986, a mathematical model based on ordinary differential equations was introduced to take into account the distribution of sexual activity.

The basic reproduction number of SARS-CoV-2: a scoping review of available evidence

medRxiv, 2020
Background: The transmissibility of SARS-CoV-2 determines both the ability of the virus to invade a population and the strength of intervention that would be required to contain or eliminate the spread of infection.

Interpretation of the Basic and Effective Reproduction Number [PDF]

Journal of Preventive Medicine and Public Health, 2020
In epidemiology, the basic reproduction number (R0) is a term that describes the expected number of infections generated by 1 case in a susceptible population.

The Dynamic Effective Reproductive Number of COVID-19 during the Epidemic in Iran

Iranian Journal of Public Health, 2022
Background: We aimed to determine the generation time, the best model for estimating reproduction number (R), and to estimate the basic reproduction number (R0) and effective reproduction number (Rt) for COVID-19 in Iran.
