Epidemic threshold for the SIS model on networks [PDF]

Phys. Rev. Lett. 104, 258701 (2010), 2009
We derive an analytical expression for the critical infection rate r_c of the susceptible-infectious-susceptible (SIS) disease spreading model on random networks. To obtain r_c, we first calculate the probability of reinfection, pi, defined as the probability of a node to reinfect the node that had earlier infected it.

Quadratic growth during the COVID-19 pandemic: merging hotspots and reinfections [PDF]

J. Phys. A: Math. Theor. 56, 044002 (2023), 2022
The existence of an exponential growth phase during early stages of a pandemic is often taken for granted. However, for the 2019 novel coronavirus epidemic, the early exponential phase lasted only for about six days, while the quadratic growth prevailed for forty days until it spread to other countries and continued, again quadratically, but with a ...

Epidemiological modeling of Trypanosoma cruzi: Low stercorarian transmission and failure of host adaptive immunity explain the frequency of mixed infections in humans [PDF]

, 2017
People living in areas with active vector-borne transmission of Chagas disease have multiple contacts with its causative agent, Trypanosoma cruzi. Reinfections by T.

Examination of the risk of reinfection with hepatitis C among injecting drug users who have been tested in Glasgow [PDF]

, 2012
Unsafe injecting practices put injecting drug users (IDUs) at repeat exposure to infection with the hepatitis C virus (HCV). It has not yet been determined if spontaneously clearing one's primary infection influences the risk of reinfection; our aim was ...

Next generation sequencing sheds light on the natural history of hepatitis C infection in patients that fail treatment [PDF]

, 2014
Background and rationale of the study: High rates of sexually-transmitted infection and reinfection with hepatitis C (HCV) have recently been reported in HIV-infected men who have sex with men and reinfection has also been described in monoinfected ...

HCV epidemiology in high-risk groups and the risk of reinfection [PDF]

, 2016
Injecting risk behaviours among people who inject drugs (PWID) and high-risk sexual practices among men who have sex with men (MSM) are important routes of hepatitis C virus (HCV) transmission.

A fractional-order model for CoViD-19 dynamics with reinfection and the importance of quarantine [PDF]

, 2021
Coronavirus disease 2019 (CoViD-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Among many symptoms, cough, fever and tiredness are the most common. People over 60 years old and with associated comorbidities are most likely to develop a worsening health condition.

Optimal Control for Tuberculosis with Exogenous Reinfection and Stigmatization [PDF]

arXiv, 2021
The effect of stigmatization is hindering the control of diseases. Especially in the case of exogenous reinfection, this effect can play a massive role. We develop in this paper, based on a tuberculosis model of Feng et.al. a model with exogenous reinfection and stigmatization.

Genetic relatedness of infecting and reinfecting respiratory syncytial virus strains identified in a birth cohort from rural Kenya [PDF]

, 2012
Background: Respiratory syncytial virus (RSV) reinfects individuals repeatedly. The extent to which this is a consequence of RSV antigenic diversity is unclear.

Backward bifurcation, basic reinfection number and robustness of a SEIRE epidemic model with reinfection [PDF]

arXiv, 2022
Recent evidences show that individuals who recovered from COVID-19 can be reinfected. However, this phenomenon has rarely been studied using mathematical models. In this paper, we propose a SEIRE epidemic model to describe the spread of the epidemic with reinfection.
