Ebola
Brianna Phelps
AKA Ebola Haemorrhagic Fever, an agressive filovirus virus
Symptoms
Ebola causes pain in the abdomen, chest, joints, and muscles. Other symptoms include chills, dehydration, fatigue, fever, loss of appetite, malaise, or sweating. Gastrointestinal symptoms include diarrhea, nausea, and vomiting. Coughing up blood, eye redness, headache, mental confusion, red spots on skin, or sore throat are also common.
Causes
Ebola is transmitted to people from wild animals and spreads in human population through human to human transmission.
People get it through direct contact (through broken skin or mucous membranes in the eyes, nose, or mouth) with: blood or body fluids like urine, saliva, or sweat of a person who is sick with or has died from Ebola, objects like needles and syringes, that have been contaminated with body fluids from a person who is sick with Ebola or the body of a person who has died from Ebola or infected fruit bats or apes and monkeys.
Immune Cells
In a lab by "TNAS," CD8 T cells expressed markers of activation and proliferation. Taken together, the results suggest that all four (Ebola) patients developed strong immune responses during the strongest/most symptomatic phase of Ebola virus infection.
Replication
When the Ebola virus invades the host's body, it immediately searches for a host cell. It begins by weakening the cell wall with enzymes and injects its nucleic acid into the cell. The virus' DNA or RNA strand incorporates itself into the cell's genetic material. Any time to cell's nucleic acid undergoes mitosis, the viral nucleic acid does as well, so its replicating itself inside the cell without destroying it.
Vaccines/Treatments
One of the reasons that Ebola is so deadly is because it has multiple ways of interfering with the human immune system. While the virus is busy destroying the human body, the immune system is either still trying to discover the problem, or is so messed up that it would be nearly impossible to make an effort to fight the invader.
