Ebola virus, the Ebola hemorrhagic fever (EBHF) caused by it is the deadliest viral hemorrhagic fever in the world today, with an extremely high mortality rate. What is the concept of
? The mortality rate of
is about 13.5%, the mortality rate of SARS virus is about 15%, while the mortality rate of Ebola is more than 50%, and in some areas it can even reach about 90%!
In front of Ebora, new crown and AIDS are both "little brothers".
According to the degree of danger, the world-wide biosafety level is generally divided into level 4: AIDS is level 2, SARS virus is level 3, and Ebola virus is level 4.
"level 4", which means "two fast, one no.":
copy quickly, die quickly, and there is no special vaccine medicine.
From 2014 to 2015, Ebola was once called the "Plague of the Century" and broke out in West Africa continent, causing nearly 10,000 infections and deaths.
After Ebola virus enters the human body, it will become an invincible copying machine, with infinite copying.
The Ebola patient is described in the documentary "National Geography":
"I can only watch the patient turn into a pool of blood in front of me."
And we will face the return of Ebola,
, and it is the most severe challenge in 20 years.

Here, it is a village in Madudu County, Mubend District, central Uganda, about 80 kilometers west of the capital Kampala , and is also the known "source" of the Ebola outbreak.
Ebola isolation area of Mubend Regional Referral Hospital
On September 11, 2022, a 24-year-old local man suddenly started to have a high fever, cough, vomit, and bloody stool. What's even more terrifying is that His eyes began to bleed.
In the next four days, the young man's family took him to visit two private hospitals, but neither improved...
On September 15, he was referred and urgently isolated to the regional referral hospital (RRH). Then the blood sample was rushed to the Uganda Virus Research Institute (UVRI) in Kampala...
On September 19, the results came out:
He was infected with Ebola virus.
The same day, the young man died of illness.
At the same time, his six family members had similar symptoms,
Then, all 6 people died!
This is Ebola, and in a moment, the disaster of extermination.
Not only did all seven people die in the family, but even the four medical staff who had previously contacted the young man were all infected, including a doctor from Tanzania .
Ebola virus is not like the new coronavirus and can be transmitted through the air, but it can be transmitted between people through direct contact with body fluids and a contaminated environment. If the mourners contact the corpse directly, a funeral may turn into countless...
The young man had contacted 42 people during his lifetime, and almost all of them were infected!
On the 6th day after his death, 36 people were diagnosed and 23 people died.
The average age of the case was only 26 years old!
Just 2 hours before the publication of Melon , the young man was finally transferred to the hospital and there was also an infected person, and 1 death had just happened...
And these infected people came into contact with 223 people.
clouds have covered this city of 1.68 million people.
virus is like Pandora's box. Once
is opened, disasters are hard to stop.

What impact does Ebola have on us in Africa? The answer to the front page of
CBC is:
seems far away, but as long as there is one case, the city gate has fired.
There is only one flight distance between civilization and viruses.
Because, dangerous viruses from tropical rainforests can arrive at any city on the earth by plane within 24 hours.
On October 7, the Biden administration of the United States announced that
will start a comprehensive screening at five major airports in the United States!
New York Kennedy International Airport, Washington Dulles International Airport, Newark Liberty International Airport , Chicago-O'Hare International Airport and Atlanta Hartsfield-Jackson International Airport, All passengers from Uganda must undergo a temperature check and fill out a health questionnaire after arriving in the United States. Health departments across the United States will conduct tracking and testing on travelers three weeks after they leave Uganda.
At the same time, U.S. Centers for Disease Control and Prevention (CDC) intends to conduct temperature checks and risk assessments on people who have been to Uganda in the past 21 days. 21 days is the incubation period of Ebola virus.
Why do Americans attach so much importance to it?
Because, this terrible highly deadly virus once lost control, and killed at least 11 Americans.
, and, the Uganda Ebola outbreak, is a rare Sudanese virus strain, and no vaccine is available at present!
Ebola under a microscope
After decades of dealing with Ebola, humans have not found an antidote yet...
The most "terrifying" thing about Ebola is probably the tragic situation of the deceased.
"Blood Epidemic" introduces the patient's lesion process - generally, the virus incubation period is 5-10 days, and then the symptoms are revealed. The process is like infecting "zombie virus "...
first caused a fever and headache.
Then, the chest cavity will be invaded by Ebola.
Then the internal organs are organized into blood,
nostrils, anus, any hole-like place, ... Some patients even spit out the intestines. Some doctors said that in fact, the infected person "melt" in front of them... Ebola hemorrhagic fever , that's the name. Then, the Ebola virus will also invade the brain . Before dying, patients with will experience symptoms such as epilepsy and spasm , which is chilling. There are three main ways to spread Ebola virus between people: One is contact transmission . Direct contact with infected persons or animals may cause infection. Blood, urine, body fluids, excrement, secretions, vomit, , etc. Ebola virus can still survive in corpses for several days , and can also be infected when exposed to corpses and blood.
The second is injection propagation. During the outbreak of Ebola hemorrhagic fever in 1976, more than 80 of the 249 patients were infected by using unsanitized syringes in the hospital.
Third is sexual contact propagation . Ebola virus can be detected in the semen of patients with Ebola hemorrhagic fever. Even if some patients recover, there are reports that Ebola virus is still detected in the semen 2 to 3 months after recovery.
In April 2022, Congo A 31-year-old man was infected with Ebola and died a few days later, but fortunately, there did not appear to be a spread...
But this time in Uganda, was the first confirmed case on September 19. In just three weeks, nearly 900 close contacts, 64 confirmed cases and 30 deaths have occurred!
shows that this epidemic is fierce, so we must pay attention to it!
There are no direct flights to the United States in Uganda, but China has them!

In addition, a latest study this month showed that
A deadly virus similar to Ebola has spread in the monkey group and may soon be transmitted to humans.
This virus is called ape hemorrhagic fever (SHFV) . It is currently prevalent in African wild primates that mainly affects macaque arterial virus. may become the next monkey pox or even the next HIV in the future.
Developmental Biology Professor of Cell and at the University of Colorado, said: ", the animal virus has found ways to enter human cells, reproduce itself and escape some important immune mechanisms that protect humans from animal viruses. is very rare. We should pay attention to it." The symptoms of "bleeding, fever" in monkeys infected with are extremely similar to Ebola, and in experiments, it was found that can use the human protein to replicate , which is far beyond simply being able to enter cells.
HIV (HIV) was predecessored by the simian immunodeficiency virus (SIV), which first spread from African monkeys to apes sometime between 1884 and 1924 and eventually mutated into the devastating virus, HIV, as we now know.
As of 2022, more than 40 million people have died from HIV worldwide, and 2,000 people have died from the disease every day around the world.
Sawyer said: "I hope that by raising awareness of viruses that should be paid attention to, we can lead one step ahead so that if human infection starts to occur, we will respond quickly."
Since we talk about monkeys, let's talk about the chickens!
At present, Europe is experiencing the largest highly pathogenic avian influenza outbreak in history, with the number of cases and geographical distribution range setting a record!
According to the latest data from the CDC and EU Food Safety Bureau :
2467 poultry epidemics have occurred in Europe so far, and 48 million poultry have been culled!
From Svalbard Islands in the Norwegian Arctic region to southern Portugal and eastern Ukraine, a total of 37 European countries have been affected!
Don’t think that it’s just a bird, many kinds of mammals have been affected, and the risks of people working in the breeding industry are also very high!
compared with the same period, the number of infections in poultry farms this year from 6 to September was five times that of last year, and more than 1.9 million farm poultry were culled on .
The avian influenza crisis was not only in Europe, but also in North America.
At present, the United States and Canada have successively experienced severe avian influenza epidemics, and millions of poultry were hunted and killed.
This week, the Canadian health department has issued a warning: Local avian influenza cases are gradually increasing, which may affect the prices of eggs and chicken!
Due to large-scale infection, farmers can only endure the pain and euthanize poultry.
"This virus can destroy a farm within 4 days."
. In the United States, 46.8 million poultry and 2,650 wild birds have been infected.In order to prevent the epidemic from further expanding, Canada has announced a ban on importing live poultry, products and by-products from the United States.
At this stage, the price of chicken in North America has risen by an average of 10% to 14%.
Recalling in early 2009, H1N1 avian influenza began to break out on a large scale in the United States, with about 6 million people infected with . Then the epidemic quickly expanded to 14 countries and regions , and caused nearly 200,000 deaths worldwide.
This time the virus does not seem to plan to let humans go.
On October 4, the Spanish Ministry of Health confirmed that the first person infected with avian influenza in , and it is also the second patient in Europe!
