10 Most Infectious Diseases

[Background Music Starts] From slowly evolving illnesses, to those imminently
fatal death sentences, we count down the 10 most infectious diseases. NUMBER 10: Rabies
Rabies is fatal if not treated immediately. You contact Rabies typically after being bitten
by an animal (or feasibly another human) that has rabies. The thing is, you should seek
treatment any time you are bitten, because the chance of surviving Rabies if treatment
begins after symptoms pop up is about 8%. Those aren’t very good odds. Ever heard
of ‘foaming at the mouth’? That’s Rabies. The disease kills about 55,000 people every
year, and people who contract the disease must live with vicious side effects like acute
pain, violent movements, and mania. NUMBER 09: Smallpox
There’s a reason why we worked so hard to rid the world of Smallpox. Once you have Smallpox,
your body, including your mouth and throat, will become littered with pussing, fluid filled
bumps. The disease has killed 300 million since 1800 alone, but it has been around since
about 10,000 BC. Just pray that you don’t get hemorrhagic Smallpox, which causes bleeding
to occur under your skin, which sours your body, earning it the nickname, ‘black pox’. NUMBER 08: Tuberculosis
Be careful when you see someone sneeze, because that’s how Tuberculosis spreads. It’s
no laughing matter, either, as over one third of the population is infected with Tuberculosis.
However, this is likely just a latent form and the symptoms will never arrive. If they
do, however, which is about a one in ten probability, you’re in for a rough ride. Coming in at
a 50% mortality rate and killing 1.5 million people a year, Tuberculosis’s main target
is usually the lungs, but will move around attacking other organs, including a male’s
testicles. If you have a weak heart, mute this for a second—Tuberculosis can, at times,
erode the pulmonary artery, causing your lungs to fill with blood. NUMBER 07: Influenza
Influenza, more commonly referred to as the flu, is seen as less of a threat today simply
because we have the means to treat it. But, that wasn’t always the case. In today’s
day and age, people will only get the flu a couple times and get over it pretty quickly
with some over the counter drugs or an annual flu shot. However, in 1918, things were a
little different. The Spanish Flu killed 100 million people—including many young and
healthy people. The reason for this was because the flu could turn an immune system against
the patient’s body, meaning the healthier you were, the more deadly the virus became.
These days, strains of the flu are appearing to grow stronger, so let’s hope we don’t
see anything like the Spanish Flu any time soon. NUMBER 06: Anthrax
Yes—Anthrax makes this list. Why? It’s a bacterial infection that’s super lethal.
Before Anthrax became a household name after the attack on September 11th, 2001, it was
still just as lethal, and wreaked havoc all over the world. Anthrax is insanely fatal.
Even one of the ingredients is aptly named, ‘Lethal Toxin’. Anthrax is most dangerous
through inhalation, ingestion, or through broken skin. Diarrhea is usually the first
symptom, with death following within a few days to two weeks. Anthrax is one of history’s
worst villains. An island in Scotland was marked uninhabitable for 50 years after Anthrax
contaminated the area. Burning is one of the only ways to kill Anthrax—all around, it’s
a vicious beast. NUMBER 05: Cholera
Cholera is a terrifying infectious disease that has struck fear in the heart of man all
throughout history. Cholera spreads through contaminated food and water—allowing the
disease to spread like fire. It has killed millions, and to this day, kills 120,000 people
or more each year. Cholera can cause patients to produce 5 gallons of diarrhea a day. Today,
if you can find treatment, you only have about a one percent chance of dying. However, there
are strains that can kill within 2 hours. NUMBER 04: Bubonic Plague
If there is one disease that can top Cholera, it’s the Bubonic Plague. Here’s why. Bubonic
Plague has one death toll at 100 million that swept Europe in the Middle Ages, and then
another death toll from the Roman Empire that knocked out 50 million people. The Roman Empire
at its peak topped out at an estimated 90 million people—accounting for 20% of the
world population at the time. That means the Bubonic Plague decimated a huge portion of
the globe in one swoop. Sadly, such a massive disease is transmitted by simple rat fleas—which
also die. Sad, we know. The Japanese also used the Bubonic Plague as a weapon against
the Chinese in World War II. If you think that’s horrific, imagine the fourteenth
century—where diseased bodies were flung over the walls of cities under attack NUMBER 03: AIDS
As of today, more than 30 million people have died of AIDS, with another 40 million listed
as infected. There’s still no cure in sight, and current methods of treatment can be very
expensive. What makes AIDS so terrifying is that it makes the human body far more susceptible
to Tuberculosis, hepatitis, and several forms of cancer. We’ll do our part and spend the
next few moments saying something very important. Safe sex will save your life. You do not want
AIDS. Using protection against STD’s and HIV is the smartest thing you can possibly
do. Be safe. Always. NUMBER 02: Ebola
Ebola is incredibly lethal if not treated immediately. Some outbreaks have seen upwards
of 90% and higher mortality rates. Native to central Africa, cases in the 1970’s started
cropping up due to what was found out to be indigenous wildlife. But, that’s about as
specific as it gets. No one truly knows where Ebola came from. Humanity believes that some
animal species carries it, but we have no idea what species that is. If you contract
Ebola, pain can start anywhere in the body—resulting in multiple organ failure and certain death
within most untreated cases. Those who do get treated, however, can make a full recovery.
No one has used Ebola as a biological weapon yet, though that is a major fear that permeates
all throughout the world. NUMBER 01: MRSA
We’re not sure why this is, or how it came to be, but the disease makes modern medicines
unusable. MRSA contains what’s known as a ‘Superbug’ which causes boils and lacerations
of the skin—and can kill within 24 hours. All strains of MRSA that exist are resistant
to our modern day antibiotics. Why? These strains, unlike other, more treatable diseases,
are far more pathogenic—and brutal. MRSA can cause a flesh eating condition, systemic
infections, a flesh eating infection that targets lung tissue, bone infections, bloodstream
infections, and an infection that targets the heart. The scariest part is these diseases
show that they’re getting stronger. Perhaps the use of antibiotics by mankind will come
at a terrifying price.
