Once contaminated, the bacteria quickly multiples and kills its host by producing two lethal toxins. In most cases, the disease in its viral pneumonia form has a fatality rate of about 70 percent with the highest fatality rate among victims over the age of 65. However, plague can be spread from person to person where as malaria cannot. This list has been compiled alphabetically to further the cause of convenient readability. This could even happen across species as is the case with the potentially lethal H5N1 Bird flu. This vector-borne infectious disease still has outbreaks of more than 500 million per year with anywhere between 1-3 million deaths when not treated properly. Cholera is one of the most infectious diseases and is easily passed through contaminated food and water. Mind you these are recent developments brought to lite over the past 10yrs or so. The Japanese also used weaponized bubonic plague against the Chinese in World War II.Ebola is highly contagious with evidence that it can be spread via air. However, alie, malaria really isn’t a disease. Aids didn’t come from Homosexuality, Homosexuals have been around since the start of mankind/human nature/cave man and Aids wasn’t discovered until 1981. we all know AIDS was just a manmade virus to kill people off.Viruses were just basically created to use as a biological weapon to kill people!Flus evolve and have different types of strains every year, so no true cure for the Flu!I didn’t think Aids was manmade, i know someone who lived through the time of Aids! Not only that but it evolves rapidly within the body to the extent that evolutionary trees can be made from virus samples taken in different parts of the body.TB is highly contagious and easily spread through airborne droplets e.g. !As for ebola not being airborne; yes, you are correct it is fluid based. Fortunately this disease has been the only one on this list to be completely eradicated from nature since it is only contagious through humans.Perhaps one of the least lethal diseases on this list, the fatality rate of typhoid fever is only 10-30 percent. One worry is smallpox could potentially be re-engineered from digital viral genome and inserted into related pox virus.If any disease can evoke pure terror then it is Bubonic Plague. Currently bird flu is not able to spread from person-to-person, however, just a small genetic event could open the way for a major epidemic.Human immunodeficiency virus infection / acquired immunodeficiency syndrome (HIV/AIDS) works by effectively destroying the body’s defences to any number of other diseases and infections. Our editors will review what you’ve submitted and determine whether to revise the article. Laugh if you must, but it is the truth. one thing you have to understand is, Typhoid is basically Food poisoning, typhoid is not airborne or caught thru sexual contact. but what makes Typhoids so deadly and dangerous is the intense unlimited number of complications as the guy was mentioning in the above post. This is where the name “Black Death” came from. Agonising death has been known to occur in excess of 90% of cases in some outbreaks.

If intervention only occurs after the symptoms start showing there is an 8% chance of survival. It has a high transmission rate and it’s symptoms are without a doubt the worst on Earth. The most interesting part of rabies is that it makes the host terrified of drinking fluids (hyrdophobia), this in turn means that there is a less chance of the host washing the salvia from the mouth, even the mere thought of drinking causes excruciatingly painful spasms of the muscles in the throat and larynxYou go completely crazy with paralysis, anxiety, insomnia, confusion, agitation, paranoia, terror, and hallucinations, progressing to delirium…The worst part is that rabies is present in every part of the world apart from Australia and New Zealand, that means that you can catch it absoultly anywhere (outside of the forementioned countries)That was a very interesting comment.
