Have most of us already been through this epidemic without noticing?

There was plenty of time and opportunity for covid-19 to spread worldwide

The novel Wuhan coronavirus originated in Wuhan, China in December 2019 and quickly spread throughout that city. The Chinese government swiftly implemented an authoritarian quarantine wall around Wuhan and strict isolation of entire districts and cities all around China, so the virus only spread to a lesser extent throughout the rest of China.

However, the Chinese government allowed the continuation of flights from Wuhan to other cities around the world. The first country to ban flights from Wuhan was Singapore on 23 January, with the USA, Australia and other countries following suit in the first few days of February. It was not until 18 March that the Australian prime minister announced that Australians could no longer travel abroad.

This means that the Wuhan coronavirus had about two months to travel around the world and widely infect the people in most cities. This novel form of Wuhan coronavirus had a rapid infection spread from person to person compared to most other viruses. Its basic reproduction number was up to 6, compared to 2 - 3 for the common cold and 0.9 - 2.1 for seasonal strains of influenza.

This suggests that many people here in Australia were already exposed to the Wuhan coronavirus BEFORE the isolation, quarantine and travel restrictions were put in place. In other words, we in Australia already had our first epidemic of this Wuhan coronavirus before we knew its name - but ours was a silent and hardly noticeable epidemic.

"The WHO says new studies indicate that up to 230 million people may have had coronavirus and survived – more than ninety times more than the current official tally of 2.5 million confirmed cases."
