covid does not amplify existing life threatening disease
its actually for some of those that died. their existing life threatening disease that amplified the lethality of covid
in short. having a weakened immune means your immune is not fighting. and not being switched off more.
but by being in a weakened state already. its not putting up the same fight as someone with a good immune system. and so the virus gets to replicate more.. and cause more lung damage until you suffocate
the weakened immune system does not suffocate you. the replicating virus unhindered damages your lungs and suffocate you..
.. anyway to the topic question
yes some tribal clinics in africa do not have equipment to run tests on viral loads to see the progress of incubation or the progress of recovery
some tribal clinics in africa dont have the scans to see if lung damage is minor or severe.
some hospitals dont have the needed oxygen supply to cater to all patients at peak
some clinics/hospitals dont have the staffing to have 1 nurse per patient to cater to all the patients needs
some dont even have the bed capacity
covid can cause issues with other organs needing ecmo to oxygen the body. some hospitals dont have enough of these
yes when things get tense and there is a over crowding of hospitals. doctors do have to do triage and rank people on survivability and who deserves most care.
there are cases where the old and the frail have been put onto do-not-resuscitate orders. meaning they are left to succumb to the disease without intubation/life saving treatment
getting blood donations/platelet donation is a demand/supply problem aswell so in some cases yes its only given to those who need it most.
