The spreadness and control of HIV/AIDS infection using SIR-model / Nur Ain Syafiqah Yahya, Nur Aimie Aqilah Mohd Zulkefri and Nor Fatin Idayu Muhamad Ruzali.

While the international donor community has spent millions on Human Immunodeficiency Virus (HIV)/Acquired Immunodeficiency Syndrome (AIDS) prevention through educational programmes, the trend of the spread is rarely analyzed. The aim of this research is to calculate the basic reproductive number for HIV/AIDS spread awareness among community to prevent from increasing cases in the future by analyzing the basic reproductive number. Using the SIR model, this study examines fundamental reproduction numbers and makes predictions regarding the amount of infections. The global HIV/AIDS epidemic poses a threat to the workforce in the national development sector, which is why the problem has become the prime motive for this research. For a country that relies on youth labour, the decrease of such a large number of potential human resources due to this epidemic can have a significant impact on Malaysia. We also present the basic reproduction number, which is a crucial concept in infectious disease epidemiology and refers to the risk of an infectious agent spreading during an outbreak. In methodology part, we also stated step involved to outcome the result which are finding the rate of susceptible, infected and recovered population, set the value of all parameters involved and lastly substitute data and parameters value in each of compartment’s equation. The findings revealed that the forecasted for susceptible and infected HIV/AIDS cases will keep diminish while recovered HIV/AIDS cases raising year after year. This is because the rate of recovery showed that it is less than zero which means it will eventually diminish and no cases for HIV/AIDS infection. The differences between observed and forecasted susceptible, infected and recovered populations among Malaysian commitee is illustrated using Microsoft Excel as a consequence of this study. If HIV/AIDS continues to be a disaster for society, the community will become increasingly conscious of the rate of infectious agent transmission if it is not regulated.
