Many governments, the UK included, focus their policy on physical distancing - which is the most obvious eye catching thing that filled the news about Wuhan. Contact tracing often gets far less attention - yet it is the absolute key to stopping this virus. It is also relatively easy to do. It doesn't need health workers. Other countries are using civil servants, community organizations and volunteers.
Contact tracing is the key to winning. Physical distancing is buying time, like defensive tactics in a game of football. Having bought time in this way we can go into the attack, crush this virus and eliminate it from our country.
