Top Ten Most Harmful Diseases

The Top Ten

1 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.

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.

This disease is extremely nasty and although not common, always fatal and extremely unpleasant to watch. It also has a disturbingly accurate way of spreading the virus through a vigorous twiching of the nerves sending flecks of contagious, infected blood all over the place. Very worrying indeed...

2 Cancer

Cancer is terrible. My uncle died from hepatocellular carcinoma, a really bad liver cancer. I really wish cancer didn’t exist

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

I have a message that maybe can prevent cancer. Try not to eat food coloring. If you have food coloring like everyday, you MAY get cancer. Cancer can kill tons of people.

Cancer is a fatal non-communicable disease. A million people die due to cancer every year. I can say that cancer is a very dangerous disease.

3 Bubonic Plague

You serious? This is the most harmful, with treatment you have a 40% chance of death. Getting the bubonic plague can lead to the pneumonic plague meaning a near 100% chance of death if you have no treatment.

The bubonic plague also known as the black death killed almost 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 more deadly. 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 madness and put down the plague it killed. More then Adolf 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 today. It started with a sudden fever and pain in weird places followed by throwing up blood getting black things all over skin and body parts start to die, turning them black. You would have died in 2-5 days. Only 300 people who got it, 1 survived it. I am European and if my ancestors died, I would not be here. Most ancestors from Europe that had survived this thing is that their DNA ...more

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..

4 AIDS

No medicine has got for aids because of reverse transcreptace. I feel sorry for scientists that has to work hard and bind up a new molecule and invent it so that AIDS patients should live for 5 more years. Condolences for their deaths and they will be remembered.

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.

Sex, that is how it's caused. It's sad cause everyone wants to have a family, but if you are unlucky enough, you will get aids. Look at Freddie Mercury.

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

5 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 definitely be at the top!

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.

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

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

6 Smallpox

I had then and there's a cure for it and cancer
will be cured to

My great great grampa died from it

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

7 COPD

Chronic obstructive pulmonary disease?

8 Cholera

Yes it's true cholera is the very harmful. We should aways take a injection of cholera before going to any piligrimage.

Does this even exist lol

ITS TRUE TOO BECAUSE I AGREE THAT CHOLERA IS 1 OF THE MOST HARMFUL DISEASE THAT WE EXPERIENCE. AND HOW TO PREVENT CHOLERA SMOKE AND DRUNK that's ALL THANK YOU.

9 Hepatitis B

Is a world th
Inking of anyone can't think but think hah

10 Rabies

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

The Contenders

11 Alzheimer's

It is too evil! I am Slenderman! Go to sleep...

Rarest one, but most dreadful.

It's rare for teenagers and young adults, but much more common in elderly.

Is a amnesia that anyone can think but do your assignment if you don't its okay keep it up and better luck next time thank you and I am cheredel

12 Fifth Disease
13 Influenza
14 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.

15 Heart Disease

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.

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

16 Chicken Pox

What chicken pox doesn't kill you there are worse disease out there than one that gives you red spots

17 Shingles
18 Diabetes

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

19 Measles
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 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

22 COVID-19

Yup definitely

23 Flu
24 Progeria

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