Following warnings and increased preparedness in the 2000s, the 2009 swine flu pandemic led to rapid anti-pandemic reactions amongst the Western countries. The H1N1/09 virus strain with mild symptoms and low lethality eventually led to a backlash over public sector over-reactiveness, spending, and the high cost of the 2009 flu vaccine.
For a given epidemic or pandemic, the average of its estimated death toll range is used for ranking. If the death toll averages of two or more epidemics or pandemics are equal, then the smaller the range, the higher the rank. For the historical records of major changes in the world population, see world population. [3]
This model has limits, however, because the fitness advantage of limited virulence is primarily a function of a limited number of hosts. Any pathogen with a high virulence, high transmission rate and long incubation time may have already caused a catastrophic pandemic before ultimately virulence is limited through natural selection.
Some were global, but were not as severe—e.g. the 1918 influenza pandemic killed an estimated 3–6% of the world's population. [13] Most global catastrophic risks would not be so intense as to kill the majority of life on earth, but even if one did, the ecosystem and humanity would eventually recover (in contrast to existential risks).

The term pandemic had not been used then, but was used for later epidemics, including the 1918 H1N1 influenza A pandemic—more commonly known as the Spanish flu—which is the deadliest pandemic in history. The most recent pandemics include the HIV/AIDS pandemic, the 2009 swine flu pandemic and the COVID-19 pandemic. Almost all these diseases ...
COVID-19 is expected to circulate indefinitely, but as of 2024, experts were uncertain as to whether it was still a pandemic or had become endemic. [ 2 ] [ 3 ] Pandemics and their ends are not well-defined, and whether or not one has ended differs according to the definition used.
A public health emergency of international concern (PHEIC / f eɪ k / FAYK) is a formal declaration by the World Health Organization (WHO) of "an extraordinary event which is determined to constitute a public health risk to other States through the international spread of disease and to potentially require a coordinated international response", formulated when a situation arises that is ...
