Complexity of the Basic Reproduction Number (R0) [PDF]
Emerging Infectious Diseases, 2019 The basic reproduction number (R0), also called the basic reproduction ratio or rate or the basic reproductive rate, is an epidemiologic metric used to describe the contagiousness or transmissibility of infectious agents.

The study of human monkeypox disease in 2022 using the epidemic models: herd immunity and the basic reproduction number case. [PDF]
Ann Med Surg (Lond), 2023 As of May 2022, a new outbreak of the human monkeypox (MPOX) disease appeared in multiple countries, where the 2022 human MPOX disease spread to more than 109 cases, excluding the suspected cases up to the end of 2022.

Measuring Basic Reproduction Number to Assess Effects of Nonpharmaceutical Interventions on Nosocomial SARS-CoV-2 Transmission. [PDF]
Emerg Infect Dis, 2022 Outbreaks of SARS-CoV-2 infection frequently occur in hospitals. Preventing nosocomial infection requires insight into hospital transmission. However, estimates of the basic reproduction number (R0) in care facilities are lacking.

Studies on the basic reproduction number in stochastic epidemic models with random perturbations. [PDF]
Adv Differ Equ, 2021 In this paper, we discuss the basic reproduction number of stochastic epidemic models with random perturbations. We define the basic reproduction number in epidemic models by using the integral of a function or survival function.

Basic Reproduction Number of Chikungunya Virus Transmitted by Aedes Mosquitoes [PDF]
Emerging Infectious Diseases, 2020 We estimated the weighted mean basic reproduction number (R0) of chikungunya virus based on outbreak size. R0 was 3.4 (95% CI 2.4–4.2) and varied for 2 primary chikungunya mosquito vectors: 4.1 (95% CI 1.5–6.6) for Aedes aegypti and 2.8 (95% CI 1.8–3.8 ...
