Why is coronavirus so deadly?

  1. Master of deception: ‘In the early stages of an infection the virus is able to deceive the body. Coronavirus can be running rampant in our lungs and airways and yet our immune system thinks everything is a-ok.’
  2. It behaves like a 'hit and run' killer: ‘The amount of virus in our body begins to peak the day before we begin to get sick. But it takes at least a week before Covid progresses to the point where people need hospital treatment.’ 
  3. It's new, so our bodies are unprepared: ‘This lack of prior-protection is comparable to when Europeans took smallpox with them to the New World, with deadly consequences.’
  4. It does peculiar and unexpected things to the body: ‘Covid starts off as a lung disease (even there it does strange and unusual things) and can affect the whole body.’ Like “corrupting” lung cells, clotting blood and causing runaway inflammation.
  5. And we're fatter than we should be: ‘Covid is worse if you are obese, as a generous waistline increases the risk of needing intensive care, or death.’
