background and aims: the world is threatened by disease outbreak that reaches a public health emergency of international concern, studies to inform public and agencies for effective containment strategy are necessary. several studies provided vital information of the dynamics and control of ebola epidemic outbreak in west africa. methodologies and techniques in those researches have to be revie...

in this paper, a five–dimensional mathematical model is proposed for the transmission dynamics of hiv/aids within a population of varying size. in writing the model, we have divided the population under consideration into five sub classes of susceptible, infective, pre-aids, aids related complex and that of aids patients. the model has two non- negative equilibria namely, a disease free and the...

Porcine epidemic diarrhea (PED) was recognized in U.S. swine for the first time in early 2013. A plaque-purified PED virus (PEDV) isolate (USA/Iowa/18984/2013) was obtained from a diarrheic piglet. The isolate is genetically close to other previously reported U.S. PEDVs and recent Chinese PEDVs and was virulent when inoculated into neonatal pigs.

The classical symptoms of porcine epidemic diarrhea (PED) are acute diarrhea and dehydration. The isolated porcine epidemic diarrhea virus (PEDV) CH/GDGZ/2012 strain was obtained from the feces of diseased pigs in 2012 in southern China. We report the complete genome sequence of strain CH/GDGZ/2012, which might be useful for better understanding the molecular characteristics of this virus.

cholera is an acute intestinal infection caused by consuming food or water contaminated with the bacterium vibrio cholerae. two main epidemiological characteristic of disease is tendency for create of sudden outbreaks and the ability to causing a pandemic. the objective of this study is to describe the epidemiology of the disease. this survey is a descriptive cross-sectional study based on repo...

The purpose of this report is to present Canada’s experience so far with the emergence of porcine epidemic diarrhea (PED) using a pro-active risk management approach. This approach is reflected in the actions the Canadian Food Inspection Agency took in collaboration with other stakeholders starting from the period the disease was first confirmed in United States to the time after it was confirm...

HAdV-56 is a new recombinant type isolated from epidemic keratoconjunctivitis (EKC) patients and has been sporadically isolated in Japan several times. Here, an outbreak of EKC in the city of Dalian, China involving a large number of workers in two factories was reported; this was the first outbreak of EKC associated with HAdV-56 worldwide.

Since October 2010, an outbreak of porcine epidemic diarrhea (PED) has been observed in some provinces of China. Here we report the complete genome sequence of porcine epidemic diarrhea virus (PEDV) strain LC, which was recently isolated from sucking piglets that suffered from severe watery diarrhea in Guangdong. It will help in understanding the epidemiological and molecular characteristics of...

twenty patients, a family, their neighbors, and friends; with lesions suspicious of ringworm infection, were referred to us within a period of 80 days. the source of infection was found to be 3 persian cats (a mother and two kittens) living with the family. the cats had multiple lesions around their nose and on abdomen which reveales the prevalence of cutaneous fungi both on direct microscopic ...
