Some viral diseases listed in this post were first reported elsewhere in the world, studies show
Multiple posts shared hundreds of times on Facebook purport to show a list of notable viral outbreaks between 1950 and 2019 which “originated in China”. The claim is misleading; some of the viral diseases listed in the posts were first reported elsewhere in the world.
One post was published here on Facebook on May 9. It has been shared more than 480 times.
It features an illustration of Chinese President Xi Jinping looking down at coffins draped with the flags of multiple countries; including the US, the UK, Australia and Germany.
The text underneath states:
“1957-1958 H2N2 originated in China
1968-1969 - H3N2 originated in China
1997-2004--H5N1 originated in China
2003 - SARS originated in China
2006 Bird Flu originated in China
2009 Swine Flu originated in China
2013--Porcine Pestivirus originated in China
2019 Covid-19 originated in China”.
Some of the viral outbreaks listed in the misleading posts, however, were first reported outside of China.
H2N2 (1957-1958) and H3N2 (1968-1969)
The H2N2 pandemic, dubbed Asian Flu, and H3N2 killed altogether more than two million people worldwide.
Swine flu (2009)
Swine flu, which is caused by H1N1 influenza virus, was first reported in humans in the US in 2009, the CDC states in this fact sheet. The agency added here that up to 575,400 people worldwide died from the disease during the first year of the outbreak.
Porcine pestivirus (2013)
Porcine pestivirus, an animal virus officially known as Atypical Porcine Pestivirus (APPV), was first detected among piglets in Austria in 2013, according to academic studies here and here. The virus has since spread across Europe, Asia and North and South America.
Pestivirus can infect swine, cattle, sheep, goats, and other domestic and wild animals. A 2019 study published in Frontiers of Veterinary Science, a peer-reviewed medical journal, also found that APPV has been one of the “several putative pestiviruses species found in mammalian species” in recent years.
COVID-19, a disease caused by the novel coronavirus, was first reported in the Chinese city of Wuhan in December 2019, according to the World Health Organization (WHO).
As of May 18, 2020, the virus has claimed over 311,000 lives worldwide and continues to spread globally.
SARS, which stands for severe acute respiratory syndrome, is a “viral respiratory illness caused by a coronavirus called SARS-associated coronavirus (SARS-CoV)” that was first detected in the southern Chinese province of Guangdong in 2002.
As of December 31, 2003, the WHO recorded a total of 774 deaths after SARS spread to North America, Australia, New Zealand and elsewhere in the world.
H5N1 (1997-2004; 2006)
The H5N1 virus, which causes a “highly infectious, severe respiratory disease in birds” and is also known as the “bird flu”, was first reported in a goose in China’s Guangdong province in 1996, according to the WHO. The first case of a H5N1 human infection was reported in Hong Kong in 1997.
The virus re-emerged in 2003 and 2006 and has since been spread across Asia, Europe and Africa by migrating birds, according to the CDC and a 2006 study published by the peer-reviewed American Academy of Family Physicians.
As of May 2020, the WHO have recorded a total of 455 H5N1 deaths.
