Ebola (Sudan strain) outbreak in Uganda.
on September 20, the World Health Organization (WHO) stated that there was 1 confirmed case of Ebola in Uganda.
At present, Uganda has declared an outbreak of Ebola in the country .
Sudan’s Ebola strain first emerges in Uganda, WHO assists investigation
The confirmed case of Ebola in Uganda was a 24-year-old man who lived in the country’s Mubende district and died after developing symptoms, the WHO Africa office said in a statement.
“At present, 8 suspected cases are being treated in health institutions .” Relevant staff of the WHO Africa Office said that they are assisting the Uganda Health Bureau to investigate this.
The current survey results show that this is a rare Sudanese Ebola virus strain that has been detected again in Uganda after a lapse of 10 years .
It is understood that Uganda has experienced four Ebola outbreaks, the deadliest of which occurred in 2000, which killed more than 200 people.
During the 2012 outbreak, the country saw a total of 24 cases and at least 17 deaths. The death is the first Ebola death in the country since 2019 .
WHO staff said they were working closely with the Uganda Health Authority to investigate the source of the outbreak.
Uganda reportedly borders the Democratic Republic of Congo.
In the recent Ebola outbreak in the Democratic Republic of Congo and elsewhere, ring vaccination of high-risk groups was very effective in controlling Ebola transmission , but the vaccine was only approved to prevent Ebola Zaire strain, the Sudan strain has not been specifically tested.
About Ebola
46 years ago, a man named Mabalo in the Democratic Republic of Congo (Zaire) came to a local medical station for help because of continuous high fever.
After the injection of quinine, Mabalo was sent home to recuperate.
At that time, due to the lack of medical supplies and poor medical equipment, the nurses used the needles injected by Mabalo to inject medicines to many patients.
After 30 days, Mabalo’s symptoms did not improve, and finally died after medical treatment failed. 18 relatives who attended his funeral also developed the same symptoms and died one after another. In the medical aid station where Mabalo was treated, it was full of patients with the same symptoms as Mabalo.
Ebola virus fatality rate can reach 90%
Medical aid scientists investigated the simultaneous outbreaks in the Democratic Republic of the Congo and Sudan, and realized that humans may have discovered a new, unheard-of disease-causing virus and named it: Ebola virus.
In the end, in the first Ebola outbreak in the Democratic Republic of the Congo, a total of 358 people were found to be infected with the virus, of which 326 died, with a mortality rate of 91%; while among the 284 infected people in Sudan, a total of 151 people died, and the mortality rate exceeded 50%.
Today, we already know the danger of Ebola virus. It is also one of the most terrifying viruses ever discovered by human beings.
Since the discovery of Ebola virus in the past half century, the epidemic has broken out dozens of times. Most of these outbreaks occurred in Africa.
Ebola symptoms
The Ebola virus has never thought of letting humans go, and it continues to invade the normal life of human beings.
A round of Ebola outbreaks nine years ago spread the Ebola virus from central Africa to remote areas of western Africa, with an astonishing speed and scope.
The Ebola virus is so aggressive that people who are infected die within a week of showing symptoms, and there is no cure for it, and the symptoms are worse than death and excruciatingly painful.
These include high fever, blood in the stool, vomiting, syncope, and internal and external bleeding symptoms.
The scary thing about the Ebola virus is that scientists still don’t have a comprehensive understanding of it.
Although humans have a general understanding of how the Ebola virus spreads, where it comes from, and how to prevent it, when controlling the Ebola virus, Humanity is still helpless.
Five members of the Ebola virus family plus one close relative
Ebola virus is a disease-causing virus that disguises itself as a nematode and wants to invade cells in living organisms.
Like smallpox virus, Ebola virus is also divided into several types, including five viruses and one close relative virus (Marburg virus). ).
Filoviruses are very similar in shape, with a “hook”-like structure at the tip, which is completely different from the genetic material obtained from human DNA.
Filoviruses obtain genetic material from RNA.
Compared with human DNA, the RNA of filovirus is relatively “simple”. Human DNA contains 3 billion base pairs, while the number of molecules of filovirus RAN is less than 20,000.
Once the Ebola virus enters the human body, it will enter the incubation period, which will last about 4 to 20 days, until the infected person has initial symptoms: fever, headache, muscle pain, joint pain, coma, etc.
At this time, it is easy to be misdiagnosed for colds or malaria. Symptoms can then suddenly worsen, bleeding inside and outside the body, and death.
Ebola’s route of transmission remains a mystery
Some scientists believe that Ebola virus may be transmitted by bats or other migratory birds.
After the climate warms, it may affect the migration routes of bats and migratory birds, which leads to the spread of Ebola virus.
More than a dozen years ago, scientists have begun to develop drugs and vaccines to treat Ebola as people’s understanding of the Ebola virus has grown.
But studying this highly dangerous virus remains challenging:
Pathogenic microorganisms can be divided into four biosafety levels according to the degree of danger, of which the first level has less impact on humans, and the fourth level is the most terrifying, which can cause deadly diseases and may spread through various channels, and the Ebola virus belongs to A quaternary virus.
