Ebola, this is known as the most well-known virus in human history. For decades, Ebola has been looming in Africa like a god of death, mourning everywhere it went. This is the largest and widespread epidemic since Ebola was discovered to infect humans in 1976.
As of 21 November 2014, a cumulative total of 15,351 Ebola cases have been reported worldwide, including 5,459 deaths. Between 2014 and 2016, there was a massive outbreak of Ebola in West Africa, which, according to the World Health Organization, killed more than 13,000 people, making it the largest Ebola outbreak in the history of the period.
Through the efforts of medical teams around the world, the epidemic was finally eliminated. However, in May 2018, the Ebola virus suddenly returned to the Democratic Republic of the Congo in Central Africa and spread to dry for ten to 2020 in 2019, and the number of infections and deaths is still increasing in the latest data from the World Health Organization's official website.
Looking at it, since July 2014, the word Ebola has appeared more and more frequently in front of the public, and the Ebola virus, the grim reaper from Africa, seems to be spreading its wings during this period. By at least April, the plague had killed dozens of people in some West African countries.
On 29 July, the death of Doctor Shek Khan, who led Sierra Leone's fight against the worst Ebola outbreak in history, caused worldwide mourning. Just a few months later, Ebola left the african continent for the first time through a civil airliner, causing the Ebola virus to wreak havoc in West Africa while extending its tentacles of terror to North America, Western Europe and South Asia, becoming a major public health event affecting the world, with cases and deaths far exceeding all previous outbreaks combined.
No one could have imagined that a class IV biosecurity virus had been discovered not far from Washington, D.C., in the capital. Incidentally, this is the most dangerous, how will people react at this time?
You know, this is an incident found in a laboratory where the level of safety is not enough, and someone even smelled the sample with their nose during the research, you know? Antibodies and antigens are like keys and locks, specific keys can generally only open the corresponding lock, unfortunately, the serum of Ebola patients opens this mysterious lock.
However, all the people who had contact with these monkeys, including the researcher who stepped forward to audition the culture flask, were found to be infected with the virus after isolation and examination, but none of them became infected with the infection. In fact, the Ebola outbreak that led to the unprecedented scale of the West Flight was the Zaire type, which is the most ferocious type of Ebola, with a fatality rate of 60%-90%.
Some say that if the spread of the virus cannot be controlled from the source of Africa, then Ebola will come to China sooner or later. How terrible is Ebola? This has to start with another story in 1976, when the hospital of Yambuku was used as a base, and the terrible infectious disease washed more than 50 surrounding villages in a short period of time, some with high fevers, some with stiff bodies, some with headaches, rolling underground.
After the onset of the disease, the condition will deteriorate rapidly within a few days, and later the patient will begin to bleed all over the body, and blood will ooze from the nose, gums, and conjunctiva of the eyes. Some people do not appear to have obvious bleeding on the surface, but the internal organs have begun to dissolve, and severe bleeding can cause hypotension and shock, and what awaits them is undoubtedly death.
Locals could not understand why the patient was sent to a medical center, where he ended up bleeding, discolored skin, and even buried in a traditional funeral ritual after death. The body is highly contagious, and the family can only look through the barbed wire and then watch as the medical staff bury the yellow body bag into the soil.
Many people are convinced that Ebola is a curse, and if Dante wrote the tenth reincarnation of hell, it must be what everyone is seeing now. The patient was then quickly identified as a new type of virus, which the researchers named Ebola after a small local river.
Since then, this hemorrhagic fever has been known for its high intensity, but compared with other viruses, Ebola seems to be very low-key, and humans have not yet unveiled the mystery of this virus, because the mystery of Ebola is largely due to the fact that the outbreak is not regular at all, and it can be said that people are fighting a battle with Ebola virus.
If the entire battle against the Ebola epidemic is compared to a football game, if the first half of the human race is to win the first half of the Ebola battle, the world needs to attach great importance to it, actively participate in it, and fully support the affected countries in terms of human and material resources.
If the outbreak in West Africa is not effectively controlled, Ebola will spread around the world, and the risk of its introduction to China will always exist. In fact, there are results that show that the potential risk of Ebola being introduced to the mainland by air passenger does exist, but this risk is very low.
Ebola, a distant and familiar name, is a very rare virus that was first discovered in the Congo region in 1976. This is a highly contagious virus that can cause primates to produce Ebola haemorrhagic fever, and most infected people will bleed inside or outside the body, resulting in shock, death, and death horror.
At the same time, Ebola virus is also the most deadly hemorrhagic fever virus today, and infected people can be called a moving object of the virus. At present, the human-to-human transmission mechanism of Ebola virus is not clear, and some researchers believe that Ebola virus is transmitted through direct contact with blood and body fluids, in the same way as HIV, which includes saliva, vomit, blood, excrement, tears, sweat and breast milk of infected people.
The entire scientific community, including the World Health Organization, has pointed out that Ebola virus does not spread during the incubation period, but some scientists have questioned this, for example, if infected people are late, they are bound to carry a large amount of the virus in a small amount of body fluid. However, Ebola appears to have other routes of transmission, as many people infected with Ebola in Africa have been exposed to the bodies of patients.
From this point of view, one way of transmission of the Ebola virus seems to be through the flow of non-clotting and sticky blood from the dead to the living. For example, when the Zaire outbreak broke out in 1976, relatives who came to mourn kissed and hugged the deceased, or treated the deceased who was ready for burial, all fell ill 3 to 14 days later.
In fact, Ebola is not only highly contagious, but also has a fairly long latent symptom, up to 21 days. After the onset of the disease, the Ebola virus will kill the host at a very fast rate, which also brings great obstacles to research work.
