Letter to the editor: Sampling bias should be minimised when analysing influenza transmission zones involving very large countries
نویسندگان
چکیده
Russia is the largest country in the world, with a land area of 16,377,742 km2. It has 11 time zones. The land area of Russia is almost four times the combined land area of the whole of the European Union at 4,479,968 km2 [2]. We can understand that choosing one data point, i.e. the NIC for each country, eases spatiotemporal analysis. However, we are sceptical that looking at influenza activity in only one city, i.e. Moscow, gives an accurate picture of what is happening in that vast country.
