Equine influenza is a common respiratory infection of horses caused by an orthomyxovirus of the genus Influenza A. Influenza A viruses can be divided into sub-types on the basis of the antigenic reactivity of the surface glycoproteins‚ the haemagglutinin (H1-H16) and the neuraminidase (N1-N9) molecules (Fouchier et al.‚ 2005). Equine influenza (EI) is caused by two subtypes H7N7 and H3N8. Outbreaks due to H7N7 are limited as the isolation of the virus has not been reported since last two decades

Epidemiology Epidemiology is the study of health-determinant patterns in a population. It accompanies public health research and consists of gathering information on a specific area or group of people and doing research on their well being and physical health. This research can help identify trends pertaining to disease among people and whether or not such diseases are related to the habitat in which they live. These studies help to inform policy decisions and evidence-based medicine by identifying

Descriptive epidemiology describe the amount and distribution of health and disease within a population. Descriptive epidemiology classifies the occurrence of disease according to the variables of person‚ place and time. Descriptive epidemiology is important for generating hypotheses about the determinants of health and disease. By generating hypothesis‚ descriptive epidemiology provides the starting point for analytic epidemiology‚ which tests association between possible determinants and health
