SEIR Model in Spread Disease

As a country with a tropical climate, Indonesia has special problems related to tropical diseases. There are many types of this disease, it is very easy to develop and spread in tropical climates when climate change occurs. The infectious diseases discussed in this study are Measles, Hepatitis B, Influenza and Covid-19. These four diseases are deadly plagues caused by very fast-growing viruses. So its existence is very troubling for humans. Therefore we need an appropriate method to restrain the rate of development. The purpose of this study was to find out how the use of the SEIR model in mathematical models in several infectious diseases. The research method used is Literature Study, namely collecting data by conducting studies that explore several journals, books and other sources of information data. The results obtained through this study are exposure to mathematical models that can explain the spread of Measles, Hepatitis B, Influenza and Covid-19 diseases.
