Most of the history here was taken from Barry's 'The Great Influenza'
The 1918 pandemic had about a 5% mortality rate for infected patients. If you take the US population of 300 million and take an attack rate of an easily transmissible virus as 30% that would mean 100 million infected. A 5% mortality would be 5 million deaths. Even worse is that with pandemic viruses the death rate is disproportionately large in the 20-45 year age group. One in every 67 soldiers in the US Army died of influenza in 1918 and its complications, nearly all of them in a ten-week period beginning in mid-September.
Factors today that are better than 1918 include better antivirals and antibiotics and better supportive care such as oxygen therapy and ventilators.
Factors worse than 1918 include worse secondary bacterial pathogens such as MRSA (methicillin resistant staph), more overcrowding esp in major cities and a more vulnerable population with more underlying conditions including HIV, people on chemotherapy, obesity and associated diabetes.
It took roughly six weeks from the appearance of the first cases for the epidemic to peak and then abate in civilian areas, and from three to four weeks in a military camp with its highly concentrated population.
The mortality rate in 1918 at Cook County Hospital in Chicago for all influenza cases ? not just those who developed pneumonia ? was 40%. In the US hundreds of doctors and nurses were dying.
In developing countries where some of these problems are accentuated deaths rates of at least 10% seemed to be not uncommon. India in particular seemed to have been hit particular badly in 1918. In the Indian subcontinent alone, it is likely that close to twenty million died. The virus also apparently killed around 7% of the entire population of Iran and Russia. In the Fiji islands 14% of the population would die in the sixteen days between Nov25 and Dec10. In Mexico as much as 4% of the population may have died.
?This level of morbidity and mortality led to the near social collapse of many American cities and did lead to the collapse of many local governments. Fear of uncertainty and lack of trust in local authorities due to lack of truthful reporting appeared to contribute to this. This fear helped lead to the fact that many died that only needed hydration, food and rest to survive but few were willing to come to their aid. Leadership must make whatever horror exists concrete. Only then will people be able to break it apart.?(Barry, The Great Influenza)
Comparisons of today to 1918 are of course hypothetical as the viruses are different and the social and economic conditions are different. However, there does seem to be some similarities in the way the disease is tracking?.
