The 1968 influenza pandemic (the “Hong Kong flu”) was a category 2 flu pandemic whose outbreak in 1968 and 1969 killed an estimated one million people worldwide. Hong Kong flu was one of the famous influenza pandemics in history.
The subsequent 1968 influenza pandemic—or “Hong Kong flu” or “Mao flu” as some western tabloids dubbed it—would have an even more dramatic impact, killing more than 30 000 individuals in the UK and 100 000 people in the USA, with half the deaths among individuals younger than 65 years—the reverse of COVID-19 deaths in
The 1968 flu pandemic was a global outbreak of influenza that originated in China in July 1968 and lasted until 1969–70. The outbreak, which is sometimes called the Hong Kong flu of 1968, was the third influenza pandemic of the 20th century.
In February 1957, a new influenza A (H2N2) virus emerged in East Asia, triggering a pandemic (“Asian Flu”). This H2N2 virus was comprised of three different genes from an H2N2 virus that originated from an avian influenza A virus, including the H2 hemagglutinin and the N2 neuraminidase genes.
4. The WHO declared the swine flu outbreak a pandemic on June 11, 2009. 5. Between April 12, 2009, and April 10, 2010, the CDC estimates swine flu caused 60.8 million illnesses, 273,304 hospitalizations and 12,469 deaths in the U.S.
The most recent pandemic occurred in 2009 and was caused by an influenza A (H1N1) virus.
While it’s unlikely that the “Spanish Flu” originated in Spain, scientists are still unsure of its source. France, China and Britain have all been suggested as the potential birthplace of the virus, as has the United States, where the first known case was reported at a military base in Kansas on March 11, 1918.
The Hong Kong strain of influenza virus A2 may have originated in the mainland of China but this is not certain. It caused a very large epidemic in Hong Kong and spread rapidly to countries as far as India and the Northern Territory of Australia—as happened in the 1957 epidemic.
Hong Kong Flu, 1968–1969 The first cases in the U.S. were detected as early as September 1968. The number of deaths between September 1968 and March 1969 was 33,800, making it the mildest flu pandemic in the 20th century.
In 1997, an H5N1 avian influenza A virus was transmitted directly from chicken to humans in Hong Kong, killing six of the 18 people infected with 33% motality rate. The H5N1 virus in Hong Kong seemed to be rarely transmissible from human to human.
in all of them, but the only major outbreak of influenza B was in 1973-4. The highest incidence of influenza A was in the 0-4 age group in all three winters, but schoolchildren bore the brunt of infections by influenza virus B.
The Public Health Service released the virus cultures to vaccine manufacturers on 12 May 1957, and a vaccine entered trials at Fort Ord on 26 July and Lowry Air Force Base on 29 July. The number of deaths peaked the week ending 17 October, with 600 reported in England and Wales.
The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919.
Pandemics of the 20th century Three influenza pandemics occurred at intervals of several decades during the 20th century, the most severe of which was the so-called ” Spanish Flu ” (caused by an A(H1N1) virus), estimated to have caused 20–50 million deaths in 1918–1919.
