As of 14 July, the number of officially recognised cases skyrocketed, with 137 deaths, [359] making the death toll in Argentina the second highest in the world at the time, behind only the US. As of April, Brazilian airports were monitoring arrivals from affected areas, under the direction of the National Sanitary Surveillance Agency (ANVISA).
The most recent flu pandemic was the 2009 swine flu pandemic, which originated in Mexico and resulted in hundreds of thousands of deaths. [34] It was caused by a novel H1N1 strain that was a reassortment of human, swine, and avian influenza viruses.
The cost of a flu season in lives lost, medical expenses and economic impact can be severe. In 2017, the World Health Organization (WHO) estimated that the seasonal flu causes 290,000 to 650,000 annual deaths worldwide. [31] In 2003, the WHO estimated that the cost of flu epidemics in the United States was US$71–167 billion per year. [32]
The 1889–1890 pandemic, often referred to as the Asiatic flu [57] or Russian flu, killed about 1 million people [58] [59] out of a world population of about 1.5 billion. It was long believed to be caused by an influenza A subtype (most often H2N2), but recent analysis largely brought on by the 2002-2004 SARS outbreak and the COVID-19 pandemic ...
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 page summarises the figures from the WHO Influenza A Situation Updates issued roughly once every other day, [1] and since 6 July from ECDC.For each country or territory, the table lists the number of confirmed cases of swine flu on the first reported day each month, and the latest figure.
Such deaths are sometimes evaluated via excess deaths per capita – the COVID-19 pandemic deaths between January 1, 2020, and December 31, 2021, are estimated to be ~18.2 million. Research could help distinguish the proportions directly caused by COVID-19 from those caused by indirect consequences of the pandemic.
By far, the most affected country has been Chile, with more than 12,000 confirmed cases, 104 deaths, and the highest per capita incidence in the world. The World Health Organization warned about the arrival of the winter in the southern hemisphere, where there are seasonal peaks of flu, that could increase the number of infections. [1]
