Which system is attacked first by Ebola? Why is this important?

  1. The different proteins that create the particles of the Ebola virus seem to attack and destroy the most important system of the human body which is the powerful immune system. This is related to the deadly Human immunodeficiency virus which causes the same effect. This is extremely important because an individual that lacks an immune system is more likely for antigens to kill you since you are not fighting off the specific bacteria, virus, or toxins. Those infections can then become very powerful and can later become fatal if not treated immediately. Without an antibody produced by the immune system, a simple cold can become absolutely deadly without anything trying to stop it from harming the individual. The explosive attack of Ebola "sweeps through you [and] your immune system fails [while you also] seem to lose the ability to respond to viral attack" (Preston 66). After you lost the ability to protect yourself, Ebola then "does in ten days what it takes AIDS ten years to accomplish" (Preston 66). With an individual carrying the Ebola virus, the immune system will not be able to carry on the immune response that attacks the organisms that might be harmful to the human body and cause disease. The immune system is made up of cells, tissues, and organs that distinguish the virus or bacteria from the body's own healthy tissue. Ebola is as deadly as it is because of it's complex way of attacking the immune system and becoming dominant over the human body.

  2. Bryan, did you mean Ebola is similar to or related to HIV when you stated "This is related to the deadly Human immunodeficiency virus which causes the same effect." Can you tell me a little bit about the viral families both Ebola and HIV come from?

    1. Ebola is very similar to the Human immunodeficiency virus in many different ways. Both viruses react and attack an individual's body in similar parts and have common symptoms that later become fatal. The reason why these viruses are so deadly is because of their first encounter to attack the immune system. The immune system is what keeps all bad substances in your body out. Both of the viruses had outbreaks in Africa and are both transmitted by direct contact with an infected individual's body fluids as well as Hepatitis C which infects the liver and causes excessive vomiting like Ebola and HIV. They are currently no cure or vaccine for Ebola or HIV but there is now treatment for it. Measles is very similar to Ebola and HIV as well as influenza but measles and influenza do indeed have vaccines but they do share complementary symptoms.

  3. When the Ebola virus enters the host’s body, it first targets the host’s immune system. This is important because once the virus weakens the immune system, everything else in the host’s body becomes vulnerable. When the immune system can no longer defend the body against foreign invaders (in this case, the Ebola virus), it starts targeting other organs and tissues. Some symptoms of the Ebola virus include excessive hemorrhaging and some results include the liquefying of organ tissues and organ failure. The virus began to damage organs in the host’s body but because the immune system is greatly weakened, it cannot repair the damage, and ultimately allows its host to die.
