Influenza transmission model by age group in Thailand

Abstract

Influenza virus is the most common disease in both children and adults. People can be infected with this disease several times a year. It is a viral infection of the respiratory tract, including the nose, throat and lungs. Age structure influence on the spread of influenza disease. In this research, we apply the dynamical model to describe the transmission of Influenza virus. We consider the age group of patients. We divided into 2 age groups. The first group (children) is the group of people’s age less than 15 years old. The second group (adult) is the group of people’s age greater than 15 years old. We separate the population into children and adult. The conditions for local and global stable are found. The basic reproduction number of the disease is found. The way for reducing this disease is introduced.
