Dr. J. F. J. Sykes, in his interesting " Public Health Problems pointed out that in the ancient world, flight was the only resort in the presence of epidemic disease, and that to this fact may be ascribed the depopulation, ruin, and disappearance of many cities of antiquity. Approaching more modern times, the spirit of combating rather than fleeling from infection appeared, and it assumed the f...

Abstract Point process models, such as Hawkes and recursive have recently been shown to offer improved accuracy over more traditional compartmental models for the purposes of modeling forecasting spread disease epidemics. To explicitly test performance these two in a real‐world ongoing epidemic, we compared fit outbreak data on Ebola virus (EVD) Democratic Republic Congo 2018–2020. The were est...

In January 2014, approximately 9 months following the initial detection of porcine epidemic diarrhea (PED) in the USA, the first case of PED was confirmed in a swine herd in south-western Ontario. A follow-up epidemiological investigation carried out on the initial and 10 subsequent Ontario PED cases pointed to feed as a common risk factor. As a result, several lots of feed and spray-dried porc...

in this paper, we present a binary-linear optimization model to prevent the spread of an infectious disease in a community. the model is based on the remotion of some connections in a contact network in order to separate infected nodes from the others. by using this model we nd an exact optimal solution and determine not only the minimum number of deleted links but also their exact positions. ...

Background Previous studies have suggested associations between trends of web searches and COVID-19 traditional metrics. It remains unclear whether models incorporating digital lead to better predictions. Objective The aim this study is investigate the relationship Google Trends symptoms associated with confirmed cases deaths. We develop predictive forecast epidemic based on a combination conve...

The full-length genome sequence of a variant porcine epidemic diarrhea virus (PEDV) strain, CH/GDZQ/2014, was determined. The isolate was a variant strain with a relatively far relationship with the PEDV strains previously identified in the same area between 2011 and 2012 and was genetically distinct from the CV777-based vaccine strain currently being used in China.

Abstract Background Ensemble modeling aims to boost the forecasting performance by systematically integrating predictive accuracy across individual models. Here we introduce a simple-yet-powerful ensemble methodology for trajectory of dynamic growth processes that are defined system non-linear differential equations with applications infectious disease spread. Methods We propose and assess two ...

Epidemic keratoconjunctivitis is usually caused by infection with an adenovirus, generally type 8 (Hanna, Jawetz, Mitsui, Thygeson, Kimura, and Nicholas, I957). As this is a DNA virus it might be expected to respond to treatment with 5-iodo-2'-deoxyuridine (IDU) which acts by interfering with the normal synthesis of DNA, thus preventing replication of DNA-containing viruses (Herrmann, I 96 I; S...
