Learning to live with Covid19 is not quite the same as living with flu or measles or dengue. These infections are nowhere as infectious or as deadly as Covid19.
If a person gets flu or measles, the person is relatively isolated, lies in bed for a week or 10 days and gets well again. Everyone else else goes about their business.
But with Covid it is different. Everyone else could be infected and could face potentially life threatening situations.
Even with vaccines, unless some form of an effective treatment and medication is found to reduce the intensity of covid...'living with it' is going to be very difficult.
