Top Ten Most Harmful Diseases


The Top Ten

1 Cancer

Cancer is a fatal non- communicable disease. Million people die due to the cancer every year I can say that cancer is a very danger disease.

Do not use the things which can cause you cancer. But if you do not care yourself by not avoiding smoking then before smoking first think about your family left behind you after your death

Yes you are right cancer is really dangerous people die EASILY FROM CANCER at least 40 % of the people survive it

2 Ebola

Cancer is a really deadly virus, yes. But cancer comes from one body system. Yes, I know that tumors cause damage to organs. However, at least cancer has treatment and far more supportive care than Ebola!

With this hellspawn, there is no cure, just like cancer. But this... this doesn't have any treatment! Wanna know how you rid of Ebola? Your body has to do it.
Cancer forms tumors that damages organs, but you can rid of those before it damages any! If you get Ebola, your organs are messed! It turns them into a liquid, except for you spleen. It turns you spleen into a rock, pretty much.
The only thing you get from this is supportive care, and you get much more of that if you have cancer.

This deserves to be #1. Cancer comes in as second, but no where close to being as bad as this nightmare.

Ebola is a disease straight from hell. It isn't funny at all. It killed over 10,000 people alone. It bleeds you to death and it has no cure. I thought having a period was bad enough but ebola is so lethal that if you get it, your organs are literally dead! Pray for the victims of Ebola and lets hope this disease gets completely wiped out. - ItsDaWorldOfSNuGGLEZ

Cancer is a horrible disease, but Ebola is just a messed up thing! I wonder why people pay attention only to cure cancer, while Ebola getting little to no attention. I'm not saying cancer shouldn't be cured, it should, but since Ebola is even worse than cancer, we HAVE to pay attention to it as well. - BorisRule

You can catch Ebola, you can't catch cancer. Even though cancer is really bad, you can't catch it.

Because the patients are not willing to go for basic hiv checkups... They feel very shy to convey this problem to others...

I think AIDS is a very sad, deadly disease. I am sorry for the people who have AIDS. AIDS can come from a type of blood transplant.
- A 13 year old girl

Look at what AIDS did to Freddie Mercury

What are the effects? Well, they are very deadly. Even though aids can not kill you by itself. It destroys your immune system, so much that it can’t even fight the common cold. Antibiotics don’t help either. If you are a victim of this, I feel the deepest sympathy for you and your family.

4 Bubonic Plague

The Bubonic Plague, or known as the Black Death, if I am correct, it killed almost 1/3 of Europe Population, plus there was no cure

Back when this really spread was a bad time. They thought it was caused by punishment from God. Some of them wipped themselves and carrying around big crosses. They interrogated either Jews or Muslims out of suspicion of them poising the water.

"Plague". Says it all.. - Strobo

The bubonic plague also known as the black death killed all most all people in Europe in the dark ages a couple thousand years after the roman empire fell a deadly plague that is more deadly then cancer most people don't even know about this plague so they think cancer is deadly more the black death is not known how it started mostly people think it was the rats some think it was the bad air but some think it was God's mad and put down the plague it.killed. More then adof.Hitler in WW2 he killed 6 million the black death killed 25 MILLION don't believe me? LOOK IT Up. And it is still killing to day it started with a sudden fiver and pain in weird places followed by throwing up blood getting black things all over sken and body parts start to died turning them black you would died in 2 - 5 days only 300 people who got it 1 survived it I am European and if my anterior die not.survived I would not be here. Most anterior form Europe had made this thing is there DNA that helps them fight ...more

6 Malaria

This should be number one. It isn't because it isn't a know disease and not many people have it. Sorry if this sounds offensive in anyway. But it should defiantly be at the top!

The deadliest thing on earth, which is just caused by a mosquito, ouch. So how is this not top of the list! P. S I have malaria so help! Hi

This disease is estimated to have killed about half of the people who have ever lived. Hundreds of billions of deaths. No disease can compare, and no disease ever will.

My mom was in Pakistan. She got bitten by a mosquito that carried malaria. She almost died - SoloPotato

13 Heart Disease

Having a heart disease can be dangerous so try to keep your heart safe

Heart diseases are bloodblocking. The heart attack can kill you. I don't want you to die, I am worried about death. Don't eat an unhealthy diet. Don't smoke. These two things can cause heart disease.

14 Chicken Pox
15 Influenza
16 Shingles
17 Diabetes

It is the disease which will remain with you throughout your life

18 Obesity

The most preventable disease. The disease that most people are not aware of. The most versatile disease which can cause CANCER, DIABETES, CARDIOVASCULAR DISEASE, MENTAL ILLNESS, SHORTER LIFE SPAN and so on... It not only harms inside but OUTSIDE too, bullies and insults are just few of them. 2/3 of America suffers from it which no one gives a damn about.

Huh didn't know it was a disease - darthvadern

19 Leprosy

Horrible people last long spread it you don't die within 1 month minimum I think there could be an out break even Canada had 12 cases.

20 Yellow Fever

Yellow fever is HORRIBLE I don't know why you didn't put it on the top 10 worst diseases now I had to put it in as 53

21 Tuberculosis
22 Progeria

It causes children to age quicker, making them die waay too soon

Look up Adalia Rose to see how terrible this disease is - ItsDaWorldOfSNuGGLEZ

Look up Hayley Okines. She has it

23 Fibrodysplasia Ossifican
24 ALS

You know what's overly sickening? The fact that some people have the literal audacity to put things such as hepatitis b above als, which is one of the most devastating diseases in existence. Might as well be a less hyper form of crippling autism.

25 Rabies

Not that harmful anymore because it is really rare. Only 1 US case in 2014 (you can read a RD article about it.) - DontMakeARookieMistake

26 Dengue Fever
27 Dysentery

Sickle Cell is a terrible disease that can't be avoided 😥 - ItsDaWorldOfSNuGGLEZ

41 Fatal Familial Insomnia

100% death rate and no explanation needed. - 50

42 Multiple Sclerosis
43 Common Cold
44 Crohn's Disease

Suprised this wasn't on the list! I have this disease so I can tell you what it is! So basically there will be a bunch of sores in any part of your gastrointestinal tract, I have in my collons. If you don't take treatment every morning and evening you will get ill! If you never take your treatment you will eventually die! You see how dangerous it is? At least you can't catch it, but that's not saying that much to be honest. If you're born with it, then good luck having that disease your whole life (it's not as terrible as many of the diseases above but it should be higher on the list)! - darthvadern

45 Henoch-Schönlein purpura

I had this in fourth grade in December 2014! You will get a bunch of red dots on your body (specifically your lower parts) and it's dangerous if you're an a adult, luckily I got it when I was still a child but I was only lucky! - darthvadern
