major systems of ebola
There are several major systems that are affected by Ebola virus infection. These include:
1. Immune system: Ebola virus targets cells in the immune system, specifically monocytes, macrophages, and dendritic cells. It impairs the normal functioning of these cells, compromising the body's ability to mount an effective immune response against the virus.
2. Hematological system: Ebola virus causes severe damage to blood vessels, leading to internal bleeding and hemorrhage. It also affects the clotting pathway, resulting in abnormal bleeding and coagulation problems. This can lead to bleeding from multiple sites, such as the gastrointestinal tract, nose, gums, and skin.
3. Gastrointestinal system: Ebola virus can cause severe gastrointestinal symptoms, including abdominal pain, diarrhea, vomiting, and nausea. These symptoms can result in dehydration and electrolyte imbalances, which further exacerbate the severity of the infection.
4. Respiratory system: Although respiratory symptoms are not typically prominent in Ebola virus infection, severe cases can lead to respiratory distress and respiratory failure. This is usually due to the overall systemic impact of the infection rather than direct damage to the respiratory system.
5. Cardiovascular system: Ebola virus can cause cardiovascular complications, including low blood pressure (hypotension), rapid heart rate (tachycardia), and shock. These complications are often a result of fluid loss, vasodilation, and direct viral damage to the heart and blood vessels.
6. Central nervous system: Ebola virus can invade the central nervous system, causing neurological symptoms such as headache, confusion, and seizures. In severe cases, it can lead to coma and death.
It is important to note that Ebola virus affects multiple body systems simultaneously, leading to a wide range of symptoms and complications. The severity of the infection varies among individuals and can lead to death in a significant number of cases.
