Victoria has a 2,550km land border with other states, including with South Australia, which peaked at 10 active cases over the same time period.&lt;p&gt;The evidence shows that strict quarantining and early lockdowns prevent spread even when there&amp;#x27;s an outbreak on the other side of a land border, and it also shows that being an island doesn&amp;#x27;t help at all if you &lt;i&gt;don&amp;#x27;t&lt;/i&gt; do this (see also: the United Kingdom). I don&amp;#x27;t know why people constantly act like Australia and New Zealand only succeeded because they&amp;#x27;re islands when they were locking cities down at single digit case counts while the United States and India were packing stadiums full of people when they were getting tens of thousands of new infections a day.</text><parent_chain><item><author>greenwich26</author><text>The average age in many African countries is in the mid teens, and we know that age is one of the strongest risk gradients.

I&amp;#x27;d argue that borders remained open in many countries areas largely due to a lack of will. You could certainly close borders to most tourists and business travelers in any country that does immigration control, like Australia did. You can also close interstate land borders, like Australia did. You can even close borders to major cities, like Australia did. You don&amp;#x27;t need to close borders to food deliveries, just budget for the logistical headaches. You do have to pay the political and economic cost though. Australia was watching with both envy and horror when we started seeing stories of British people able to go on holidays to Europe again.</text><parent_chain><item><author>greenwich26</author><text>The average age in many African countries is in the mid teens, and we know that age is one of the strongest risk gradients.
