Top Ten Most Harmful Diseases


The Top Ten

1 Cancer

You are living a normal life; in several months or even less, you're in hospice. Scary to think about; cancer could be unpredictable. - illusion

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 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

One of the most deadliest in existence in this planet. - illusion

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

3 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

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

Don't forget to wear condoms

5 Smallpox

It really only affected early Europeans who came to America because they did not have any resistance to it in their immune system - MSA33

I had then and there's a cure for it and cancer

My great great grampa died from it

6 Malaria

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.

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

19 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.

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

46 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

47 Nephrotic Syndrome
