This bioweapon do not need more triggers. It has built in triggers which comes as mutations, which then create waves. There are more that 600-700 variants world wide and growing as we speak.
No preparation, no hospitals with oxygen can save people other than lockdown, early isolation, border checks and vaccination.
Please try to understand from a doctor’s perspective. Just having a community acquired pneumonia case in ICU we rush to get high risk consent from the relatives of the patient. The rate of prognosis is slashed 50% straightaway sighting first X-ray.
It is the time that an Intensivist tries to buy for the patient. With good resources and hands on approach Patient can be saved. But this do not happen all the time. I am only factoring in treatment part dispensed by the Hospital assuming Patient's immunity is fighting well and there are other intrinsic factors protecting him. And when the system gets overwhelmed and doctors and resources get over stretched the probability of coming out healthy becomes bleak.
This is biological war we are fighting, having more hospitals, more ventilators, more doctors, more nurses is ideal but the outcomes are not assured.
