As news of the spreading Ebola virus is reported around the
world, the threat posed to thousands of people across several
continents is becoming clear. The terrible effects of the disease
may be shocking, but a review of history suggests that the
emergence of a pandemic with a global scope is anything but
unusual.
Though significant scientific and medical advances mean that
many long-standing diseases are technically treatable, recent
years and decades have shown the persistent problem of poor
social conditions in exacerbating epidemics which have broken
out. For many living in poorer countries and socially
disadvantaged areas, medical treatment to combat viruses may
simply not be available. Yet, the cost of allowing such
conditions to remain are great. Given the unprecedented inter-
connectedness of modern-day economic life, and the growing
virulence of some viruses, a disease which at first appears to be
a local or regional challenge, can very rapidly expand to pose a
global danger. In no particular order, the following list
indicates some of the deadliest diseases, almost all of which
continue to be present today.

12. Cholera
Though a long-standing problem in India, cholera emerged as a
truly global threat in the 19th century. The spread of the water-
borne disease was related to a combination of factors,
including the expansion of trade and economic activity, as well
as changing living patterns. Global trade meant that the disease
was transmitted across continents and claimed many lives,
even in the most advanced countries. The high number of
deaths was also attributable to the concentration of more
people in cities, as a consequence of the industrial revolution.
Often living in poorly ventilated, overcrowded and inadequate
housing, those living in the inner cities provided the ideal
environment for Cholera to run rampant. For example, in
London in 1832, 55,000 people lost their lives, and during
1867, over 100,000 people died in Italy. The disease remains a
problem today, however, generally only in developing
countries.

11. Dengue Fever
An infection common in tropical countries, Dengue Fever has
been known about for several hundred years. Efforts were
begun early in the 20th century to develop a vaccine to cure
the virus, which is spread to humans from mosquitoes.
Projections suggest that anywhere from 50 to 100 million are
infected by the condition annually, and that out of these,
25,000 will die. Trials continue to identify a possible cure. At
the beginning of 2014, reports stated that testing remained in
the human efficacy stage.

10. SARS
Severe Acute Respiratory Syndrome (SARS) emerged in 2003,
developing into a serious public health crisis in China and
later, internationally. SARS is believed to have originated in
animals and represented a new type of virus. It infected more
than 7,000 people in 2003 and was responsible for the deaths
of over 500. In Canada, Toronto was struck by the most serious
outbreak outside of Asia, resulting in 32 deaths by June 2003,
and the WHO issued a travel advisory warning against travel to
the city.

9. Spanish Flu
As if four years of all-out war were not enough, Europe and
America were struck by the Spanish flu virus in 1918. The
pandemic lasted almost two years, targeting young adults who
had the strongest immune systems. The devastation brought by
the virus was extensive, with estimates putting the dead at
between 20 and 50 million. To put this into perspective,
projections of the number of military deaths in the First World
War, which had just concluded, are over 16 million. Research
continues into the specific properties of the flu strain which
broke out in 1918, in order to better understand and deal with a
future pandemic.

8. Ebola
Since its discovery in the mid 1970s, the disease remained
confined overwhelmingly to rural areas of west Africa. Until
this year, that is. The disease is spread by infected bodily
fluids. The dramatic speed with which Ebola has broken out of
its traditional regions is posing severe dangers to public health,
not only in the three west African countries currently baring
the brunt of the epidemic, but also throughout the world. Some
countries, like Canada and Australia, have responded by
closing their borders to travellers from the region. There are
several efforts under way to produce a vaccine capable of
treating the illness, and some of the initial results are expected
in the coming months. To date, the current outbreak has killed
over 5,000 people in west Africa, according to the World
Health Organisation (WHO).

7. Lassa Fever
Victims of Lassa Fever exhibit Ebola-like
symptoms. Discovered in the late 1960’s, it’s yet another
disease with its origins in west Africa. To date, working on a
cure has not made it beyond the early testing stages. Causing
roughly 5,000 deaths per year and accounting for between
300,000 and 500,000 cases, the danger posed by Lassa Fever is
considerable.

6. Bird Flu
The H5N1 strain of flu, better known as avian or bird flu, is so
called because it first emerged in poultry stocks in Asia. In
2005, public health organizations warned of a global pandemic
as the virus began to spread outside of the Asian region,
reaching Europe. Although the number of cases of human
deaths continue to be relatively low at several hundred, the fear
remains that H5N1 could become much more dangerous if it
mutates, thus enabling the transmission of the virus between
humans.

5. Winter Flu
It may surprise you to know while reading about some of the
most deadly diseases that seasonal flu is one of them. Although
vaccinations against the threat of flu are widely available, a
steady number of cases, some of which result in death, occur
each year. In Canada, since 2009, there has not been a winter in
which less than 100 deaths have been recorded, with the lowest
figure being 104 in 2011-12. The elderly, children and people
with weakened immune systems are most often targeted. But in
2009-10, as a result of the H1N1 strain, broader layers of the
population were infected and the number of deaths rose.

4. Smallpox
The only disease on this list that no longer threatens our health,
Smallpox was eradicated entirely through sustained
international collaboration in vaccination programs in the
1970s. But prior to that, it had been the scourge of many
societies throughout history. The last reported death from
Smallpox came, curiously enough, in 1978 in Birmingham,
England, following a laboratory accident which produced a
mini-outbreak.

3. HIV/AIDS
Believed to have originated in west Africa, HIV/AIDS gained
increasing prominence as it spread globally. The virus
gradually weakens the immune system with the result that
many sufferers die as a result of another infection, which they
are incapable of fighting off. Although drugs are available to
treat the condition, they are often hard to obtain in some of the
areas worst affected, such as sub-Saharan Africa. One of the
countries impacted most severely is South Africa, where
according to figures published by the department of health in
2012, 29.5 percent of mothers attending antenatal clinics had
HIV. It is thought that approximately 40 million people are
living with the condition globally, many of whom are unaware
of their condition.

2. Tuberculosis
Linked with malnutrition and overcrowding, TB is yet another
disease which has a disproportionate impact upon the poor. It
is spread by the breathing in of bacteria, is extremely
contagious, and its presence is not always apparent. This is
because people can either be infected with latent or active TB.
Though the latent variety will not make you feel sick, the
bacteria can become active at any time. The disease’s severe
impact over the years is reflected by its frequent portrayal in
various literary works. It was referred to by Dickens in Nicolas
Nickelby as the “dread disease,” and made a regular
appearance in Russian novels of the 19th century. TB is further
complicated by its links to other viruses, the main one being
HIV/AIDS. A significant percentage of those suffering from
HIV also have TB, and the disease is at least three times more
likely to become active in people with HIV.

1. Diarrhoeal Diseases
Despite being both preventable and treatable, diarrhoea
remains the second most common cause of death for children
under the age of five, globally. Figures in 2012 attributed over
a million deaths to diarrhoea, and a total number of 1.7 billion
cases. It thrives in environments with dirty drinking water and
a lack of sanitation, meaning that developing countries are at
high risk.
