It was a fascinating learning experience during the IIAP learning journey. The cognitive experience was a lifetime learning journey that I will not forget. It involves detailed reading, brainstorming, discussion and respecting each other's views. Before the discussion, I was not aware that infectious disease can be so impactful to individuals, countries or even the world. As I had been through in China where all citizens need to follow the government policy during a pandemic. As the course went on, I had learnt how to do research on the issue through peer discussion and projecting my opinion.
