Expository essay What You Didn t Know About Ebola .

The Ebola virus originated in 1976 in the Bahra Ebola region of southern Sudan and Zaire, now the Democratic Republic of the Congo. The origin of the virus is unknown. The virus is transmitted from wild animals to humans and spreads among people through human-to-human transmission.

However, based on the available evidence, it is thought that fruit bats (Flying Foxes) may be the host of the Ebola virus.

"Ebola" is the name of a river in northern Zaire, the Democratic Republic of the Congo. In 1976, an unknown virus came to the area, killing people in 55 villages along the Ebola River, causing hundreds of lives, some families to be spared, hence the name "Ebola virus".

Three years later (1979), the "Ebola" virus ravaged Sudan again, and corpses were everywhere for a while. After two "atrocities", the "Ebola" virus mysteriously disappeared for 15 years and disappeared without a trace.

Outbreaks in Zaire since January 1995 and Gabon since February 1996: 316 cases and 245 deaths in Kikwit, Zaire, with a case fatality rate of 78%; In Ogooue Ivindo, Gabon, there were 46 cases and 31 deaths, with a case fatality rate.

Scientists have done a lot of research on the Ebola virus, but they have not been able to find the source of the virus. The first outbreak of Marburg virus occurred in 1967 when the patient was exposed to a herd of African green monkeys transported from Uganda. Therefore, it is believed that the Ebola virus is likely to be found in animals in nature.

In October 1989, the Primate Quarantine Center in Leston, USA, received a batch of monkeys from the Philippines. During the quarantine process, the monkeys fell ill and died one by one. When the monkeys' blood was examined, it was found that the monkeys were infected with the Ebola virus.

Fortunately, the Reston Ebola virus is not pathogenic to humans and does not cause illness in humans. But this finding reminds us that the Ebola virus is likely to be like the Marburg virus in monkeys, orangutans and other non-human primates. But it was later discovered that non-human primates were also victims of the Ebola virus.

During the 2001-2003 Ebola haemorrhagic fever outbreak in Gabon and Congo, French scientists captured thousands of different animals, including bats, birds, squirrels, etc., in endemic areas and tested them for Ebola virus. As a result, evidence of the existence of the Ebola virus was detected in the bodies of 29 bats, and it is suspected that bats could be the culprit in the transmission of the Ebola virus. The study also found that some of the characteristics of the Ebola virus are similar to those of a variety of retroviruses that can infect birds, and it is speculated that the Ebola virus and the retroviruses circulating in birds may be the same ancestor.

In 2008, the United States was assisting the Philippines in quarantining some sick pigs and found that pigs could be infected with the Ebola virus.

This is despite growing evidence that the Ebola virus is transmitted from animals to humans. But so far, the exact ** of the Ebola virus remains unclear.

It is the polluted environment of Africa. The place is unhygienic, and all kinds of garbage are piled together, resulting in the production of a mutated bacterium, which is called a virus because it cannot be killed and can be infected. Many animal areas in Africa are very different kinds of garbage heaps, which are very unsanitary and dirty.

The virus happens to be exposed to animals and then infected when people go to catch them. Then when I returned to the village, I spread it to everyone. Think about why there are no outbreaks of this deadly virus in so many countries around the world, but there are always outbreaks of various viruses in Africa.

The Ebola virus spreads so quickly that blood, saliva, urine and other body fluids are the source of infection, and without any precautions, a large number of infected people will appear immediately.

Because the lethality rate of this virus is very high, people often die before they can wait for medicine, and there is no very good specific medicine.

Because the medical conditions in Africa are relatively poor, there are many local people, and there is a lack of scientific medical awareness.

China is talking: Professor Chen Wei talks about the origin of the Ebola virus.

Introduction: There are some documentaries that can attract people's attention and learn relevant information, such as what are the highlights of the popular science short film "Ebola Virus"? <>

First of all, this short film makes people aware of the dangers of the Ebola virus, although the transmission rate of the Ebola virus is not particularly high, but the fatality rate is very high. Generally, the probability of complete infection is very low, so this short video makes people aware of the dangers of the Ebola virus, and in addition, this short video also tells people how to prevent the Ebola virus. The way to prevent Ebola is to wash your hands frequently, pay attention to personal hygiene, and avoid contact with some undesirable substances, because Ebola virus is mainly transmitted by contact, not through the respiratory tract.

At the same time, this popular science video also makes people aware of how the virus is produced and how harmful the virus is to people, so that people can have more awareness of the virus, and this short film is still very worth watching. <>

In fact, the most important thing after the emergence of the virus is timely prevention and development of relevant vaccines, and after the development of vaccines, people can prevent these viruses, especially those who work in places where the virus may occur, relevant medical staff and some staff, if they can get this vaccine in time, they can also protect their own safety. In addition, the emergence of the virus is inevitable, so there is no need to panic excessively, what human beings should do is to pay attention to personal hygiene, timely prevention of the virus, so as to ensure their own safety. <>

Popular science short films like this are very worth watching, and I hope that there will be more excellent popular science short films, so that public health awareness can be raised, and people's health can be guaranteed. It's also a very good format, so hopefully there will be more popular science short films to appear.

This work has a lot of highlights, first of all, this work is very reflective of reality, through this work, people have popularized the relevant knowledge and key points of the Ebola virus, the actors' acting skills are also very good, and there are also some emotional scenes in the play, which are very delicate.

It can let us understand the spread of the virus, there are many touching stories, the embodiment of the power of Chinese doctors, in the process of treating others, the epidemic situation encountered, and the dangerous situations encountered, all of which are interesting, and this work is very touching.

The highlight of this short film is how to express the spread of the virus, how to convey people's views on the virus, what kind of methods are there in the face of the virus, what kind of isolation skills are there, and what kind of panic the virus has brought to the society.

The short film vividly exposes the pathogenesis of the Ebola virus and its principles in the form of animation, showing the horror and spread of the virus in a humorous way, and explaining in three minutes how the virus is even more terrible than the new crown and the symptoms and reactions.

Formation of the Ebola virus:"Ebola" is the name of a river in the northern part of the Democratic Republic of the Congo (formerly known as Zaire). In 1976, an unknown virus came to the area, killing people in 55 villages along the Ebola River, causing hundreds of lives, some families to be spared, hence the name "Ebola virus".

Ebola is a zoonotic virus, and despite painstaking research by the World Health Organization, no animal reservoir capable of surviving an outbreak has been identified, and fruit bats are considered to be the possible original reservoir of the virus.

Ebola virus is also known as Ebola virus. It is a very rare virus, which attracted wide attention and attention from the medical community after its existence was discovered in 1976 in the Ebola River region of southern Sudan and the Democratic Republic of the Congo (formerly known as Zaire).

Hence the name "Ebola". is a general term used to refer to a group of viruses belonging to the genus Ebola in the family Fibriviridae.

Ebola virus is a virulent infectious virus that can cause Ebola hemorrhagic fever in humans and other primates, and the Ebola hemorrhagic fever (EBHF) caused by it is the deadliest viral hemorrhagic fever in the world today, and the symptoms of infected people are very similar to Marburg virus, which is also in the fibroviridae family, including nausea, vomiting, diarrhea, skin color changes, body aches, internal bleeding, external bleeding, fever, etc.

Mortality rates range from 50% to 90%, and the main causes of death are stroke, myocardial infarction, hypovolemic shock, or multiple organ failure.

Ebola virus, biosafety level 4 (AIDS level 3, SARS level 3, the higher the level, the stricter the protection). The incubation period of the virus can range from 2 to 21 days, but it is usually only 5 to 10 days.
