Existence Of Epidemics Research Articles

A Review of State Public Health Emergency Declarations in Peru: 2014-2016.

Peru has different legal mechanisms of emergency, one of which is the Public Health Emergency that is applicable when: there is high-risk for, or the existence of an outbreak, epidemic, or pandemic; the occurrence of cases of a disease classified as eliminated or eradicated; the occurrence of emerging or re-emerging infectious diseases with high epidemic potential; the occurrence of rapid disseminated epidemics that simultaneously affect more than one department; as well as the existence of an event that affects the continuity of health services. From July 2014 to December 2016, 23 Public Health Emergencies were declared, out of which 57% were in the high-risk or existence of epidemics, 30% were due to some natural or anthropic events that generate a sudden decrease in the operative capacity of health services, and 13% were due to the existence of a rapid spreading epidemic that could affect more than one department in the country. The risk or occurrence of epidemiological outbreaks, mainly of Dengue, was the main cause of emergency declaration. One-hundred and forty million US dollars were allocated to implement the action plans that were part of the declaration, of which 72% was used to keep the operational capacity of health services and 28% to vector and epidemiological control measures.

Kawasaki disease: a matter of innate immunity.

SummaryKawasaki disease (KD) is an acute systemic vasculitis of childhood that does not have a known cause or aetiology. The epidemiological features (existence of epidemics, community outbreaks and seasonality), unique age distribution and clinical symptoms and signs of KD suggest that the disease is caused by one or more infectious environmental triggers. However, KD is not transmitted person‐to‐person and does not occur in clusters within households, schools or nurseries. KD is a self‐limited illness that is not associated with the production of autoantibodies or the deposition of immune complexes, and it rarely recurs. Regarding the underlying pathophysiology of KD, innate immune activity (the inflammasome) is believed to play a role in the development of KD vasculitis, based on the results of studies with animal models and the clinical and laboratory findings of KD patients. Animal studies have demonstrated that innate immune pathogen‐associated molecular patterns (PAMPs) can cause vasculitis independently of acquired immunity and have provided valuable insights regarding the underlying mechanisms of this phenomenon. To validate this concept, we recently searched for KD‐specific PAMPs and identified such molecules with high specificity and sensitivity. These molecules have structures similar to those of microbe‐associated molecular patterns (MAMPs), as shown by liquid chromatography‐tandem mass spectrometry. We propose herein that KD is an innate immune disorder resulting from the exposure of a genetically predisposed individual to microbe‐derived innate immune stimulants and that it is not a typical infectious disease.
