Bluetongue virus vaccine: conventional to modern approach.

Acta virologica, 2019
Bluetongue (BT) is an economically important, infectious and non-contagious disease of ruminant animals. BT disease is caused by bluetongue virus (BTV) of the genus Orbivirus (the family Reoviridae). BTV is transmitted by certain species of biting midges

The contact process with semi-infected state on the complete graph [PDF]

arXiv, 2017
In this paper we are concerned with the contact process with semi-infected state on the complete graph $C_n$ with $n$ vertices. In our model, each vertex is in one of three states that `healthy', `semi-infected' or `wholly-infected'. Only wholly-infected vertices can infect others. A healthy vertex becomes semi-infected when being infected while a semi-

A mathematical model for the within-host (re)infection dynamics of SARS-CoV-2 [PDF]

arXiv, 2023
Interactions between SARS-CoV-2 and the immune system during infection are complex. However, understanding the within-host SARS-CoV-2 dynamics is of enormous importance, especially when it comes to assessing treatment options. Mathematical models have been developed to describe the within-host SARS-CoV-2 dynamics and to dissect the mechanisms ...

Classifying Latent Infection States in Complex Networks [PDF]

arXiv, 2014
Algorithms for identifying the infection states of nodes in a network are crucial for understanding and containing infections. Often, however, only a relatively small set of nodes have a known infection state. Moreover, the length of time that each node has been infected is also unknown.

Sero-Epidemiology of Rotavirus Gastroenteritis in Children in Ilorin, Kwara State

Omosigho Omoruyi Pius , Izevbuwa Osazee Ekundayo , Saheed Ibrahim DamilareRotavirus is responsible for the most severe dehydrating diarrhea among young children due to gastroenteritis. In this study, we aimed to ascertain the occurrence of childhood gastroenteritis caused by Rotavirus among infants and young children who are younger than 5 years of age in Ilorin, Kwara State and determined the risk factors posing the challenges to be susceptible to diarrhea associated with rotavirus in Ilorin, Kwara State. Diarrhea stool samples were collected from children who passed watery stools, who met predetermined inclusion criteria and who presented at the study hospitals Viz: General Hospital and Specialist Hospital Alagbado and Children Specialist Hospital, Igboro. All within Kwara State either on outpatient care basis or those admitted into the pediatric ward. Sample of stool habouring rotavirus antigens was detected by commercial Rotavirus IgM ELISA kit to target recent infections among the participants. Out of three hundred (300) stool samples that were collected from children suffering from acute diarrhea, a total number of eighty-six (86) were found to be Rotavirus positive (28.7 %) and two hundred and fourteen (214) were found to be negative (71.3%). The age group 3-5 years, showed the highest prevalence rate which is in line with some research findings that attribute this age range with certain feeding habits and cultural practices, predisposing them to gastroenteritis. It is therefore advised that parents and guardian alike should ensure that special care is given to children, with emphasis on their feeding habits and sanitation. Keywords: Rotavirus, gastroenteritis, children, diarrhea. INTRODUCTION Rotavirus is a non-enveloped double stranded RNA viruses belonging to Reoviridae, Rotavirus is one of them, other members of this family include orthoreoviruses, obiviruses, aquareoviruses etc. (Mertens 2005). Infants and young children are often affected by diarrhea caused by rotavirus infections. There are about 128,500 deaths associated with Rotavirus worldwide each year, with 70 % of cases occurring in Sub-Saharan Africa (Jonesteller et al., 2017). Approximately 258 million gastroenteritis cases are caused b   +2 more

Numerical considerations about the SIR epidemic model with infection age [PDF]

arXiv, 2020
We analyse the infection-age-dependent SIR model from a numerical point of view. First, we present an algorithm for calculating the solution the infection-age-structured SIR model without demography of the background host. Second, we examine how and under which conditions, the conventional SIR model (without infection-age) serves as a practical ...

Viruses in the environment - presence and diversity of bacteriophage and enteric virus populations in the Umhlangane River, Durban, South Africa.

Journal of Water and Health, 2017
Due to the continued persistence of waterborne viral-associated infections, the presence of enteric viruses is a concern. Notwithstanding the health implications, viral diversity and abundance is an indicator of water quality declination in the ...
