Ebola Virus

By: Huntyr Terry

Causes

Ebola, also known as Hemorrhagic fever, is not an airborne virus. Unlike other viruses, the Ebola virus can only be spread by bodily fluids. For this reason, Ebola spreads through human-to-human transference via direct contact.

Symptoms

People may experience:

Pain areas: in the abdomen, chest, joints, or muscles

Whole body: chills, dehydration, fatigue, fever, loss of appetite, malaise, or sweating

Gastrointestinal: diarrhea, nausea, vomiting, or vomiting blood

Also common: coughing up blood, eye redness, headache, mental confusion, red spots on skin, or sore throat

Immune Cells in Immune Response

The Ebola virus replicates at an unusually high rate that overwhelms the protein synthesis of infected cells and the hosts immune defenses. The host then has a strong inflammatory response that is equally bad. Both the adaptive immune and inflammatory systems respond to the infection at the same time.

Steps for Virus Replication

When the virus infects the host's body it immediately searches for a host cell. and begins these steps:

1. Attachment- The virus attaches to a host cell.

2. Viral Entry- The virus enters the endosomes of the cell by macrophinocytosis or clathrin-mediated endocytosis.

3. Sequential Transcription- During transcription RNA is transcribed in to seven mRNA's that will become individual viral protein carriers.

4. Replication- Once the viral proteins rise something tells the cells to switch from translation to replication.

5. Budding- The newly replicated cells start budding, destroying the cell.

6. Release- Now the virus is released from the cell.

Prevention of Ebola

There is no vaccine for Ebola.

If you are going to a part of Africa where there has been an outbreak:

Wash your hands often and practice hygeine carefully

Do not handle any items that have come in contact with an infected person

Avoid contact with bats and nonhuman primates or blood

Avoid funeral or burial services of those who might have had the virus

Treatment of Ebola

There is no cure for Ebola. Scientists are making experimental vaccines and treatments that are under development, but they have not yet been fully tested for safety or effectiveness. The doctors monitor the patients by maintaining the patients oxygen levels and blood pressure as well as treating other infections that may occur when people have Ebola. Supportive care, hydration with oral fluids and the treatment of specific symptoms improve the likeliness for survival.

The Ebola virus goes through the Lysogenic Cycle
