We are allowed to go shopping for groceries, to visit the doctor, and to get a bit of exercise if we stay local. The reason we are doing this is to stop the spread of Covid-19 and to save … Read More

Dr Matt Boyd, Prof Michael Baker, Prof Nick Wilson The Global Health Security Index which considers pandemic threats has just been published. Unfortunately, NZ scores approximately half marks (54/100), coming in 35th in the world rankings – far behind Australia.

Dr Matt Boyd, Prof Nick Wilson, Dr Osman Mansoor & Prof Michael Baker Should an island nation like New Zealand close its borders in the face of a severe pandemic threat?

Infectious diseases are far from defeated. They pose a unique health threat because they are caused by living micro-organisms. This biological fact has two important consequences: firstly it means that these micro-organisms are constantly evolving to exploit new ecological opportunities, and secondly they are transmissible (they spread from person-to-person and from infected animals and contaminated environments). The constant evolution of … Read More

In another life I used to sit on teams that developed something called ‘clinical guidance’. We would draw together published evidence and make recommendations on what best practice should look like.
