This is one of the commonest misunderstandings about current restrictions. While we wish the elderly and vulnerable all the best, the restrictions are primarily about protecting our hospitals and healthcare system from becoming completely overwhelmed. None of us have pe-existing immunity, and it is quite an infectious virus, and if everyone gets sick at the same time, you have Italy, UK and USA on your hands. The health system is overwhelmed.
And the result of that is that the other people who continue to get sick, with the usual diseases, can’t get care. No cancer surgery for the 30 year old mum with breast cancer/ melanoma, , no heart surgery for the 45 yo dad who has a heart attack, no IVF, no brain surgery, no aneurysm surgery, can’t get operated on quickly enough for appendicitis, bowel rupture, emergency Caesarian section. Imagine being in a car accident and arriving in an emergency department where all the corridors are full of patients dying of Covid 19. Not to mention the over 100 health care workers in the UK who have died because they didn’t have enough appropriate protective equipment. And down the track, when front line health workers walk away from their jobs en mass, unable to cope with PTSD. That is what we have dodged, and what other countries will suffer from.
And where is the proof this will ever lead to herd immunity? There is no herd immunity to the common cold or the flu. Maybe a vaccine will come, maybe not Maybe an antiviral will come, maybe not. Maybe we will all have to take our chances with the virus in the long run, and maybe more than once, but if the health system becomes overwhelmed at any stage, then lots and lots of patients who don’t have Covid19, and lots of healthcare workers, will suffer seriously too.
