10 Ebola

The AIDS also made its first appearance in Africa. When it has started to spread, anyone who caught it was already dead, for there was no cure for it back then. Today, fortunately, there are some drugs used for treatment, thanks to the advancement of medicine industry, but sadly not all countries have access to them, leaving the death rate relatively high. At this age, a lot of people are living with HIV, and since it is infectious, everyone around the patient should take the necessary precautions. However, this virus is still one of the devastating ones, because it works on utterly destroying the immune system, leaving the victim prone to many other infections and diseases. In other words, if this virus was ever caught and left without treatment, it would result in an unpleasant sequence of diseases.

8 Rabies

Rabies is a disease as old as time, has been around for so long. This virus is caught through the bites or scratches of infected animals, especially dogs and bats. If anyone has ever fallen as a victim of these dangerous bites, they should immediately head to the nearest hospital and get treatment through vaccination, otherwise the virus, within few days, will creep into the central nervous system, disrupting it completely and immediately sending the victim to death. Some people have argued that the symptoms of this virus make it so much similar to being turned into a zombie, because the bitten person, in some cases, can become insane and perform violent acts, and this actually explains its name since Rabies means Madness in Latin. Certainly killing stray dogs is never fun, but at least now you can see the local authorities viewpoint.
