VIRUS-PREVIOUS-FACTS
Last century’s epidemics far more deadly than 21st century’s
PARIS, April 11, 2020 (BSS/AFP) – Before the emergence late last year of
the novel coronavirus, which has now killed more than 100,000 people, the 21st
century’s epidemics had been far less deadly than the pandemics of the
previous century.
Here are the major epidemics of the last two centuries, starting with the
most recent:
– Ebola: 2013-2016 and 2018-to date –
The deadliest epidemic of the haemorrhagic fever Ebola broke out in West
Africa in December 2013 and lasted more than two years, killing more than
11,300 people, mainly in Guinea, Liberia and Sierra Leone.
First identified in 1976, Ebola is less contagious than other viral
diseases, but is particularly lethal, killing around 50 percent of cases.
The virus re-emerged in August 2018 in the eastern Democratic Republic of
Congo where it has so far killed more than 2,200. On April 10, 2020 a new case
was reported, just three days before a deadline that would have marked the
official end to the epidemic.
– Swine flu: 2009-2010 –
The World Health Organization (WHO) says 18,500 people died of “Swine flu”,
or H1N1, which was first uncovered in Mexico and the United States in March
2009.
The Lancet medical review, however, puts the toll at between 151,700 and
575,400.
The pandemic alert was launched on June 11, 2009 and lifted on August 10,
2010 but the virus turned out to be not as deadly as first feared.
Vaccines were rushed out, but in hindsight, the West, particularly Europe,
and the WHO were criticised for overreacting at a time when annual influenza
epidemics every year kill between 250,000 and 500,000 people, according to the
Geneva-based UN health agency.
– Bird flu: 2003-2004 –
The deadly H5N1 strain of bird flu killed more than 400 people, mainly in
Southeast Asia, after appearing in 2003. It first ravaged poultry farms in
Hong Kong, before being transmitted to humans. The WHO declared a global
health emergency, but the toll remained limited.
– SARS: 2002-2003 –
Severe Acute Respiratory Syndrome first emerged in southern China in
November 2002 before sparking a health crisis in mid-2003, in particular
traumatising Asia.
It killed 774 people, four fifths of whom were in China and Hong Kong. It
was transmitted to humans from horseshoe bats, eventually spreading to around
30 countries. It had a mortality rate of 9.5 percent.
– AIDS: 1981-to date –
AIDS is by far the most deadly epidemic of modern times: according to UNAIDS
some 32 million people around the world have died of the disease which affects
the immune system and leaves people vulnerable to opportunistic infections.
Today around 24.5 million people have access to retroviral drugs which, when
taken regularly, efficiently stop the illness in its tracks and heavily reduce
the risk of contamination.
– Hong Kong flu: 1968-1970 –
Around one million people died of the Hong Kong flu, according to the US
Centers for Disease Control and Prevention (CDC).
Transmitted around the world between mid-1968 and early 1970, it in
particular killed many children. It first started in Hong Kong, spread through
Asia and reached the United States in late 1968. After lying low for several
months it then hit Europe in late 1969.
– Asian flu: 1957-1958 –
Around 1.1 million people died of Asian flu, according to the CDC.
The pandemic hit in two aggressive waves. The virus first appeared in
southern China in February 1957. Several months went by before it reached
America and Europe.
The disease, which results in serious lung complications, in particular
affected the elderly.
– 1918-1919: Spanish flu –
Spanish flu hit a large part of the world’s population in the wake of World
War I, killing up to 50 million people, according to the CDC.
Striking between September 1918 and April 1919, it is considered the most
deadly in history over such a short period.
Five times more people died of it than did in World War I. The first victims
were recorded in the United States, before it spread to Europe and then around
the world.
Its mortality rate was estimated at more than 2.5 percent, according to the
CDC.
