How is Ebola doing its harm?
When a person becomes infected with Ebola, the virus damages the body's immune (免疫的) cells, which defend against infection, said a researcher at Lancaster University. But if a person's immune system can stand up to this attack, then he is more likely to survive the disease.
The patients that survive it best are those who don't get such a bad disadvantage in immune system. But if the body isn't able to get rid of this attack, then the immune system becomes less able to regulate (调节) itself. This means the immune system is more likely to run out of control,
leading to a drop in blood pressure, multiorgan failure and eventually death.
What are the common symptoms of the disease?
Fever. Headache.
Joint and muscle aches.
Weakness.
Diarrhea.
Vomiting.
Stomach pain.
Lack of appetite. Chilis. Rash. Redness in the eyes. Hiccups. Cough. Sore throat. Chest pain. Difficult breathing or swallowing. Bleeding inside and outside of the body.
How to prevent the spread of Ebola?
Ebola can be spread primarily via direct contact with patients, specifically the blood and fluids of an infected patient.
We should avoid contact with infected patients and objects such as clothing, bedding, and needles used by them. Avoid areas where infections have been reported. For now, the disease has only been confirmed in central and West Africa, four cases in America and Europe. Avoid eating wildcaught bush meat. Researchers have suspected that the disease came to humans via animals, probably through the meat of primates (灵长类). If you're in an area where the disease has been reported, avoid purchasing, eating, or handling wild game to stay on the safe side.
