Mr. Goh clearly doesn't understand the definition of epidemic. COVID has been an epidemic since 2019 and it is still an epidemic. On the hand, Endemic simply means constant existence of a particular disease, eg. flu, malaria, common cold, rabies, chickenpox etc.
Why endemic COVID is becoming less of a concern. Let me give you a example, chickenpox Why did people die from chickenpox was a common thing before the invention of vaccines? Is second infection rare? Why? Why are people with second infection much milder? ->It's all because of our immune system's ability to create memory cells to fight against the similar pathogens
Why do you think Delta variant is pretty much extinct in the west now? It's because of immune system as well. Omicron is much more contagious and infect majority of the people. By this way, these people have developed immune response against COVID antigen which help to fend off Delta variants which were way less transmissible. That's why Delta were displaced by Omicron
It's never to the advantage of the virus to kill you. All viruses want to be the common cold, just give you the sniffles while you go around infecting others. They just want to live and reproduce.
Mark my words, COVID will only become MILDER and MORE CONTAGIOUS in the future.
