Accurately determining Covid-19’s death rate not only puts to bed conjecture suggesting the disease isn’t all that dangerous, it allows health services to prepare, and governments to intervene to, for example, protect elderly people, says Gideon Meyerowitz-Katz​, a University of Wollongong epidemiologist who has spearheaded research on the topic. M THE GEOGRAPHY AND MORTALITY OF THE 1918 INFLUENZA PANDEMIC K David Patterson and Gerald F. Pyle The 1918 influenza pandemic spread over the entire world in less than six months and killed tens of millions of people, many times more than have been killed in any other outbreak of infectious disease thus far in the twentieth century. Reliable IFRs for the Spanish Flu, 2003's Severe Acute Respiratory Syndrome (SARS), and the Middle East Respiratory Syndrome (MERS) outbreak aren’t readily available. 23 November Results. No matter how the second wave developed in New Zealand, it was many times more deadly than any previous influenza outbreak. In middle-aged adults the IFR is ‘’two orders of magnitude’’ (this is an awful lot) greater than the yearly risk of a deadly car crash and ‘’far more dangerous than seasonal influenza’’, the study found. At the time, many believed that the A(H1N1) virus had arrived on board RMS Niagara, which berthed in Auckland on 12 October 1918 after sailing from Vancouver and San Francisco. The Maori population were more severely affected with a mortality rate of 42.3 per 1000 people. But as they are more infectious, they may well end up killing more people.

The exact details of the flu’s arrival in New Zealand remain a mystery. A death rate of 3.4 per cent was terrifying. The standard planning model assumptions are based on the infection and case fatality rates of the 1918 influenza pandemic in New Zealand, that is a 40 percent infection rate, with a 2 percent case fatality rate, giving a population mortality rate of 0.8%. According to the latest data … For the most recent data and more information visit FluView: Influenza-Associated Pediatric Mortality.

The second and more deadly wave of a new strain of influenza arrived in New Zealand in October 1918. Last year, a US study that had not yet been reviewed by other scientists, suggested the death rate was only 0.12 per cent.
