Hepatitis B

Viral hepatitis is a global public health problem affecting millions of people every year, causing disability and death [1].The hepatitis B virus (HBV) is transmitted through the contact with the blood or other body fluids of an infected person. For formulating evidence-based policy of Public Health and data for action we should know about main ways of transmission HBV and population group with high risk of infection.

Objective

To develop model to study risk factors for hepatitis B (HB) and to identify the main causes affecting the incidence of HB.

In the United States, 800,000-1.4 million people are chronically infected with hepatitis B virus (HBV); these persons are at increased risk for chronic liver disease and its sequelae. Current national viral hepatitis surveillance is a passive laboratory-initiated reporting system to state or local health departments with only 39 health departments reporting chronic HBV infection in the National Notifiable Disease Surveillance System. Since active HBV surveillance can be expensive and labor-intensive, the ICD-9 coding system has been proposed for surveillance of chronic hepatitis B.

 

Objective

To evaluate the sensitivity, specificity, positive and negative predictive values of the ICD-9 coding system for surveillance of chronic hepatitis B virus infection (HBV) using data from an observational cohort study in which ICD-9-coded HBV cases were validated by chart review

The standard approaches to simulation include solving of differential equation systems. Such approach is good for obtaining general picture of epidemics (1, 2). When the detailed analysis of epidemics reasons is needed such model becomes insufficient. To overcome the limitations of standard approaches a new one has been offered. The multiagent approach has been offered to be used for representation of the society. Methods of event-driven programming give essential benefits of the processing time of the events (3).

Objective:

To develop multiagent model of hepatitis B (HBV) infection spreading.
