The idea of a pandemic is part of evolutionary medicine, and a bit of research puts us in a good position to improve our immune system and prevent dismay.
I have an autoimmune disease, and have had it for decades, which means that for me every year’s flu season is potentially lethal. I take some precautions:-
I take at least 1000mg of Vitamin C a day to support my immune system, if I catch flu, which for me is a 5 monthly event I increase the dose substantially; when the headache gets bad, or the nose is totally blocked I take a 1000mg pill which gives substantial relief in 20 to 30 minutes. I do not take aspirin (salicylic acid) or acetaminophen (paracetamol) because they both interfere with the body’s ability to fight the infection, and are poisons in their own right.
Vitamin D is vital, and the ability to get vitamin D from food is limited, better to supplement if there is an identified threat.
Zinc and selenium are usually too low in western diets and contribute to immune system problems, Brazil nuts provide an adequate amount of selenium, but 4 to 5 a day is sufficient, selenium is poisonous in anything but trace quantities so don’t take too many.
Zinc is present in nuts such as almonds, but supplementation may be more reliable.
Yah has everything under control, It is to Him that we must look if this gets really bad, you will hear Spanish Flu mentioned time after time, but Spanish Flu may well have been caused by overdose of aspirin. https://www.sciencedaily.com/releases/2009/10/091002132346.htm
Beware of rushed ‘cures’ and ‘treat the symptoms’ type medicine, Big Pharma does not profit from vitamin C sales but it is an easy over-the-counter treatment. Sars was a coronavirus too, see this British Medical Journal article:
Don’t panic and have faith.
