A good explanation, sorry if it has nothing to do with............
How is the coronavirus likely to play out, how does it end, and does our behaviour make a difference? Here infectious diseases expert Dr Siouxsie Wiles walks us through the epidemic curve, with illustrations by Toby Morris.
But before we get to that, let me just explain epidemic curves in a little more detail. First, they have three parts: a start (phase one), a middle (phase two), and an end (phase three). Each of these phases is influenced by different things. Such as, how infectious is the virus or bacterium? How is it transmitted? Is it person-to-person, or from eating or drinking? If it’s person-to-person, are people infectious before they have symptoms and don’t know they are unwell? And if people do have symptoms, are they mild enough for people to go about their daily routine? Is everyone susceptible to the infection, or just some people? What resources do we need and have to contain the outbreak? The answers to these questions will influence the shape of the epidemic curve.
