Mathematical models of the spread epidemic diseases are studied, paying special attention to networks. We treat Susceptible-Infected-Recovered (SIR) model and Susceptible-Exposed-Infectious-Recovered (SEIR) described by differential equations. perform microscopic numerical simulations for corresponding on Comparing a random network scale-free infection, we emphasize role hubs in network. also p...

conclusions according to the results of the study, the most common causes of hospital admission were respiratory infections (e.g. pneumonia), nervous system infections, tuberculosis, septicemia, skin and soft tissue infections and utis. considering the diversity of infections, epidemiological evaluation of these diseases is essential, especially in regions with high prevalence of infectious dis...

background in vitro evidence shows that immune function is compromised in people with diabetes. therefore, infections are more common and infection-related mortality is higher in this group. accurate information about the prevalence of infectious diseases in diabetic patients can help in health care policy and support planning. we do not know the spectrum of clinical infectious diseases in our ...

conclusions: since, there are few relevant studies in our country, recent studies on infectious diseases could be used for national planning and medical requirements’ preparation, it seems that periodical assessments of these diseases are mandatory. results: during the study, 4676 children, aged 1 month to 14 years were admitted and 29% (1357) of them were diagnosed with infectious disorders, 1...

An S-Ic-I-R epidemic model is investigated for infectious diseases that can be transmitted through carriers, infected individuals who are contagious but do not show any disease symptoms. Mathematical analysis is carried out that completely determines the global dynamics of the model. The impacts of disease carriers on the transmission dynamics are discussed through the basic reproduction number...

Infectious diseases are a major burden for health (1) for both humans and animals and pose a constant economic challenge for the global economy (2, 3). Climate change, intensive global trade, emergence/reemergence of infectious agents and of antimicrobial resistance, combined with intensive livestock production systems make prevention and control of livestock infectious diseases a major global ...

Testing symptomatic individuals for a disease can deliver treatment resources, if tests’ results turn positive, which speeds up their treatment and might also decrease individuals’ contacts to other ones. An imperfect test, however, might incorrectly consider susceptible individuals to be infected (false positives). In this case, testing reduces the epidemic in the expense of potentially miscla...

Accumulated data based on experiences with curtico,teroids in the management uf infectious disea­ses, have proved that they are very dfective and ,afe drugs provided that are administered properly.  The Corticosteroids arc administered mainly be­c,1usc o; antitoxic, antiimflammatory a11d antiallcrgic effects, the cndotoxius are ncuturalized, generalized body reactions are diminished, damaged t...
