Since 2020, the Covid-19 pandemic has spread like wildfire across many countries, including Malaysia. The disease has caused disastrous impacts on the country's economy, public health system, and the livelihoods of its citizens. Hence, there is an urgent need to investigate and determine the underlying factors attributed to the high infection rate of Covid-19. This research aims to study and identify demographic factors attributed to the high infection rate of Covid-19 in Malaysia using regression models. The preliminary results show that the labour force participation rate, unemployment rate, and average household income contribute to Malaysia's high COVID-19 infection rates.
