Causal inference in environmental epidemiology: Transmission dynamic modeling & determination of effective public health measures
Research abstract
Environmental epidemiological analyses are typically restricted to non-infectious diseases. However, emerging infectious diseases are associated with environmental and socio-economic factors highlighting the importance of considering infectious diseases in environmental epidemiology. Furthermore, understanding the causal relationship between relevant determinants and the infected number is essential to recognize the transmission patterns and implementing effective public health control measures. Therefore, this study aims the development of a causal inference-based method framework for the transmission dynamics of COVID-19 and the determination of relevant environmental and Water, Sanitation, and Hygiene (WASH) factors associated with COVID-19 transmission.
