Conclusion
Different modelling approaches give different answers to the question of
how many people in the UK and elsewhere have actually been infected by
COVID-19, which all would agree in epidemiological terms is behaving
very differently from other Coronaviruses that we have seen in the past.
We have the ability through working collaboratively to build a
scientific evidence base for tackling this and future pandemics.
We are learning more and more about this virus. National policy is
changing rapidly, and COVID-19 antibody testing is increasingly being
applied (7). This will facilitate better datasets from population-based
studies. The picture will become clearer as more data accrues over time.
