Is there a virus more terrible than HIV in the world?

Is there a virus more terrible than HIV in the world? First of all, to answer this question, we need to know how terrible HIV is. Now I will tell you about the horror of HIV: HIV is not directly fatal, but the immune system function is low caused by infection. Therefore, compared with the direct lethality of many viruses, HIV is not too terrible, but it is terrible because it destroys the immune system, which is a completely different mechanism from other viruses. The following are some deadly viruses that still exist in the world and may be considered more terrible than HIV.

The first type: Herpes B virus (80% mortality) Herpes B virus is extremely harmful, with a mortality rate as high as 80%. Rhesus Herpes Virus B is a simple virus that infects rhesus monkeys and spreads from one host to another through peripheral nerve infection. The virus will affect the central nervous system, and if left untreated, it will lead to neurasthenia or death. Some important symptoms of viral infection include shortness of breath, muscle coordination and fever, which is a terrible virus.

The second type: rabies virus (mortality 100%) rabies virus is a nerve virus that causes human rabies. The virus is transmitted through animal saliva or human body fluids. Nearly 55,000 people die of rabies every year. Viral diseases of humans and animals are spread by cats, bats, dogs, monkeys and mongooses. 100% is fatal, and the virus is fatal because it directly affects the brain and nervous system of people and animals. Symptoms of viral infection may range from rabies to immobility. If symptoms appear, the mortality rate is almost 100%. I was bitten by a dog when I was a child, and I was vaccinated for a week, and I am still shivering.

The third kind: smallpox virus, which has been extinct, need not be said by me.

There are many viruses that are more terrible than AIDS. If we make a list of the most terrible viruses, HIV will not even make it into the top three. Let's take a look at those terrible viruses. (My subjective ranking, of course. I accept the rebuttal.)

First, the flu virus

Although the flu virus breaks out every year, it doesn't seem serious. However, the flu virus has different mutations every year, which makes it difficult for us to prevent it by vaccination and other means. Moreover, the spread of influenza virus is through the air, which is very easy to spread from person to person. Some mutations are fatal. For example, the Spanish flu in that year killed190,000 people in a short time, which was more destructive than HIV.

Second, Ebola virus.

A few years ago, an Ebola virus broke out in West Africa, killing 8,000 people at a time. Several of my teachers have joined medical aid teams in Africa and been to epidemic areas.

I think this virus is more terrible than HIV.

Strong infectivity and high mortality rate, and the mortality rate of infected people can even reach 90%. Patients infected with the virus will have multiple organ failure and eventually die.

Biosafety level 4 is even higher than HIV. The higher the level, the more horrible the virus is.

Third, Marburg virus.

As deadly as Ebola virus, there is no effective prevention and treatment at present, and the mortality rate after infection can reach 100%. Also known as green monkey disease virus, people and primates, such as monkeys and orangutans, will get it.

The biosafety level is also level 4.

Within one week after infection, the patient will bleed, have a high fever, vomit all over the body, and usually die within one week.

In 2004, an epidemic broke out in Africa, killing 300 people.

Relatively small, the spread is not as wide as AIDS, but the disease is very fierce.

In addition, there are Hantaan virus, SARS, avian influenza and hepatitis B virus, all of which were once great demons.

However, there are more and more trends in AIDS. Everyone should be honest and be alert to this virus.

Yes

HIV is not a terrible virus, because HIV is not contagious and can only be transmitted through blood, sexual intercourse and mother-to-child transmission, but it must be transmitted through air or contact, such as influenza virus, which is much more contagious than HIV. Secondly, the mortality rate of HIV is not high. It takes more than ten years or even decades to die after illness, and many viruses die immediately after infection.

The most terrible virus in history is smallpox virus. Almost every child was infected, 1/3 died after infection. This virus can infect and kill children efficiently, leaving children with no chance to become adults and reproduce. Population control is very effective. The eradication of smallpox is one of the reasons for the population outbreak.

The level of smallpox virus in human history is influenza virus. In 2009, 1 918-1919, the epidemic killed 50 million to1100 million people, which reduced the average life expectancy in the United States by 12 years. This makes influenza virus the biggest threat to human beings at present. Due to the high variability of influenza virus, the current influenza vaccine can only be used for one year, and once the global influenza epidemic occurs, the annual influenza vaccine will definitely not work. In history, the death toll of every global influenza epidemic has reached one million, while the death toll of an epidemic like 19 18 will reach several hundred million, and it is only a few months.

Fierce viruses must be viruses from animals, because mutation can infect humans, because they are unfamiliar with human physical environment and are extremely toxic. Like bird flu, although the mortality rate is high, it can't spread from person to person. If it can spread from person to person, then its mortality rate is not so high.

At present, the first potential virulent virus is Ebola virus. The infectivity of Ebola virus has gradually increased, and the mortality rate is still extremely high, but it has not yet left Africa.

The second is Nipah virus, with a mortality rate of 39%. More than 50% of the survivors have left a severe brain injury, which is also spread by bats like Ebola virus. In addition, there is Marburg virus.

More viruses have been found in wild animals. As long as humans continue to invade animal territory, animal viruses will continue to mutate like HIV, and then enter humans, forming a new plague.

Aids virus is not directly fatal, what is fatal is the low immune system function caused by infection with the virus. Therefore, compared with the direct lethality of many viruses, HIV is not too terrible, but it is terrible because it destroys the immune system, which is a completely different mechanism from other viruses. Here are some deadly viruses that still exist in the world that may be considered more terrible than HIV (maybe not completely collected, except for extinct viruses such as smallpox). In addition, please note that only viruses are collected here, not deadly bacteria (such as anthrax, cholera, plague, etc. In fact, it is quite terrible).

Avian influenza virus (mortality -60%)

Influenza A virus subtype H5N 1 is also called "avian influenza" virus. The deadly H5N 1 virus first infected humans in 1997, because it has killed 60% of infected patients. The virus is transmitted to humans through birds. A study conducted by some researchers confirmed why this virus is so deadly to human beings. Studies have shown that the virus can induce inflammatory proteins 10 times more than H 1N 1 virus. These viral inflammatory proteins can lead to life-threatening pneumonia and acute respiratory distress. Avian influenza is actually a deadly virus to birds. In addition to respiratory complications, vomiting, diarrhea and common flu-like symptoms are also common, and the virus can also lead to severe multiple organ failure.

Luqiao virus (mortality -80%)

Luqiao virus was named after its outbreak in Lusaka, Zambia and Johannesburg, South Africa in 2008. The first two letters of these two cities constitute the name of Lujo virus. Luqiao virus is a cruel virus with a mortality rate as high as 80%. In 2008, five people were infected and four died. Scientists say the virus is as deadly as Ebola. It is understood that the first outbreak was caused by a woman living in the suburbs of Lusaka. She had a high fever, and as time went on, her condition became more and more serious. The deadly Lujo virus is known to cause human viral hemorrhagic fever (VHF). As we all know, this virus can cause symptoms similar to Ebola virus, such as gums and nosebleeds.

Herpes B virus (mortality -80%)

Herpes B virus is extremely harmful, with a mortality rate as high as 80%. Rhesus Herpes Virus B is a simple virus that infects rhesus monkeys and spreads from one host to another through peripheral nerve infection. The virus will affect the central nervous system, and if left untreated, it will lead to neurasthenia or death. Since the discovery of herpesvirus B in 1932, there have been 3 1 cases of infection, of which 2 1 case died. This disease is rare in humans, but it can be easily spread by monkey or animal bites. It has been found that about 80% to 90% of wild rhesus monkeys carry herpes B virus. Some important symptoms of viral infection include shortness of breath, muscle coordination and fever.

Ebola virus (mortality rate as high as 90%)

Ebola virus is a rather deadly virus, and the disease it caused was once called "Ebola virus disease in Zaire". The virus was first discovered near the Ebola River in Zaire in 1976. Ebola virus disease, formerly known as Ebola hemorrhagic fever, is a serious fatal disease of human beings. The human mortality rate of the virus is as high as 90%, and the mortality rate of some Sudanese varieties is 53%. The initial symptoms of the virus are similar to common viral influenza, accompanied by sore throat, fever, muscle pain and headache. The symptoms in the next stage may be vomiting, diarrhea, bloody stool, rash, kidney and liver damage. If patients are not treated early, it may be fatal and life-threatening.

Marburg virus (mortality -23-90%)

Marburg virus is a deadly infectious virus, which can cause Marburg virus disease, also known as Marburg hemorrhagic fever. In untreated patients, the death rate of the virus is very high, ranging from 23% to 90%. In most cases, bleeding or blood loss is not the cause of death, but due to multiple organ dysfunction syndrome (MODS). The virus was first discovered in 1967, when laboratories in Frankfurt and Marburg in Germany broke out at the same time. 3 1 patient developed hemorrhagic fever symptoms, resulting in 7 deaths. Survivors of this disease have experienced long-term eye problems, hearing loss, muscle weakness, hepatitis and many other problems.

Rabies virus (mortality-100%)

Rabies virus is a nerve virus that causes human rabies. The virus is transmitted through animal saliva or human body fluids. In 2009, a severe rabies outbreak in Angola killed 93 children. Nearly 55,000 people die of rabies every year. Viral diseases of humans and animals are spread by cats, bats, dogs, monkeys and mongooses. 20 10, rabies virus in Bali, Indonesia killed 78 people. If the patient is not vaccinated, rabies virus is very dangerous, with symptoms developing and 100% death. This virus is fatal because it directly affects the brain and nervous system of humans and animals. Symptoms of viral infection may range from rabies to immobility. If symptoms appear, the mortality rate is almost 100%.

First of all, I wish all mankind in the world good health and stay away from diseases. AIDS is a disease that infects many people and is difficult to treat. Is there a virus more terrible than it? Terrible is that some viruses are more terrible than HIV, and some viruses are almost as harmful as HIV. Here is a brief introduction.

1. HIV is a virus that causes defects in human immune system. 198 1 was first discovered in the United States in and originated from chimpanzees and gorillas.

After being infected with HIV, the immune function of patients is seriously damaged, and patients are often seriously infected by bacteria and viruses, mainly causing interstitial pneumonia and acute encephalitis.

The terrible thing about AIDS is that after treatment, AIDS carriers who stop treatment often reappear HIV, and the virus is stubborn and cannot be eradicated. The average life expectancy after AIDS onset is 5.8-8.8 years.

Aids has a long incubation period and a high mortality rate. 30 million people were infected with HIV, and nearly120,000 people died.

Because of the long incubation period, HIV-infected people generally do not know that they have been infected, or conceal their illness after learning of the infection, which leads to the invisible spread of AIDS and is difficult to control.

Vaccine situation: The medical experiment conducted in Thailand in 2009 showed that the experimental vaccine can reduce the risk of HIV infection and has a certain immune effect.

Second, Ebola virus belongs to the family Fibroviridae, and it is a virulent infectious virus with high mortality rate, which can die within 24 hours at the earliest. The biological safety level of Ebola virus is higher than that of AIDS and SARS, and it needs a higher protection level than AIDS and SARS. Human infection originated from orangutans who died in the wild.

The incubation period of Ebola virus is 2 to 2 1 day, usually 5 to 10 day.

Ebola virus mainly attacks various organs, causing organ deformation, necrosis and chronic decomposition, leading to internal bleeding, brain injury and death. The mortality rate is very high, ranging from 50% to 90%. The causes of death were stroke, myocardial infarction, hemorrhagic shock and organ failure.

The most terrible thing about Ebola is its high infectivity. Transmission route: The patient's body fluids come into direct contact with skin and mucous membrane, even close contacts and even roommates may be infected, and the infection rate is about 23%.

Vaccine situation: The first Ebola vaccine of National Institutes of Health passed the clinical trial on 20 14, the vaccine developed by Canadian Public Health Bureau at the end of 20 16 can effectively protect Ebola virus, and the US Food and Drug Administration in China approved the "Recombinant Ebola Virus Vaccine" on 20 17.

Ebola virus is mainly prevalent intermittently in African countries. Although it is highly contagious and has a high mortality rate, it is only endemic.

Thirdly, SARS virus was once prevalent in China in 2003, and many people still remember it deeply. Highly contagious, acute and fatal after infection.

SARS is a severe acute respiratory syndrome, which is caused by coronavirus. It is transmitted through the respiratory tract or through contact with the respiratory secretions of patients.

Symptoms are fever, headache, muscle pain and respiratory failure.

The incubation period is 1 to 16 days, usually 3 to 5 days.

Isolation and prevention are very important. During the epidemic, the hospital has a special fever clinic, and the temperature can be measured at the airport and railway station.

Vaccine situation: There is no vaccine at present.

Plague, also known as the Black Death, is a serious infectious disease, spread by rats and fleas. There have been many large-scale epidemics in history. /kloc-About 25 million people died in Europe in the 0/4th century, and it was also very popular in China before liberation. The mortality rate is relatively high and difficult to control.

The main symptoms are chills, high fever, headache, ecchymosis and bleeding, leading to lymphadenopathy, pneumonia and bleeding.

It is divided into lung type and gland type.

The infection routes are respiratory droplet infection, rat flea bite, skin infection (skin injury) and digestive tract infection (eating infected meat), and the lung type is mainly air infection.

The incubation period is 2 to 8 days, and the onset is faster.

Vaccine situation: If there is plague vaccine, it needs to be vaccinated once a year, and once every six months if necessary. However, the vaccine cannot be prevented by 100%, and it may get sick. The onset of the disease was delayed by about 9- 12 days compared with those without vaccination.

These viruses pose a great threat to human beings. Some viruses spread invisibly, while others spread quickly. People hope that medical researchers can develop therapeutic drugs and effective preventive vaccines so that these viruses no longer pose a fatal threat to human beings.

Helicobacter pylori, I saw someone in my circle of friends that day that the infection rate of China people was 84%. After being infected by this pathogen, people stink when they talk, and they stink when they are seriously vented. Think about it. You are a normal person. You must not throw up when others talk so smelly. What's more frightening is that saliva is contagious. Think about it. You know you have this problem, and then you drink medicine hard. When you are cured, you will be infected if you come into contact with people around you. You will never be cured. You are afraid to talk to others, and you are worried that your children will have no friends at school because of poor speech. You should get up early to brush your teeth and rinse your mouth. It's really annoying I just hope you are not infected. Don't eat out.

Thank you for inviting me. There are many viruses in the world that are worse and more terrible than HIV. In fact, HIV is not bad, because it only destroys people's immune system and reduces people's immune ability. When other viruses or bacteria are infected, it is more difficult for his immune system to kill these invading bacterial viruses, so patients can compare the diseases caused by the corresponding bacteria or viruses. For example, Li San is an AIDS patient. If mycobacterium tuberculosis invades his body, he is more likely to get tuberculosis, which is extremely difficult to cure, and may eventually die of tuberculosis hemoptysis. Although there is no specific medicine to treat AIDS, after treatment, the condition of many AIDS patients has been limited. It is reported that the AIDS vaccine has also been developed and will be mass-produced in the near future. Therefore, HIV is not terrible. As long as patients actively cooperate with doctors, there is still great hope of survival.

In fact, in our human history, many pathogenic viruses that are more terrible than HIV have been found. They are highly contagious and deadly, almost to the point where people talk about them. Such as smallpox virus, SARS virus, anthrax virus, plague virus and so on. If these viruses are widespread, they may kill nearly half the population of a city or a country. For example, in A.D. 1347, Khin Chahan of the Mongolian Empire led an army to besiege Kafa, an important port in the Black Sea. At that time, the Black Death was prevalent in the army, and Qincha Khan used a trebuchet to throw the body that died of the Black Death into the city. As a result, the plague prevailed in Kafa City, and when the city was broken, it was almost no one lives. Later, Genoa merchant ships that went to France for trade brought germs back to Europe, which opened the era of the Black Death in Europe. This time, the Black Death broke out in Europe, and the mortality rate was about 40%-50%. The mortality rate in some European countries was as high as 80%. Therefore, compared with the virus mentioned above, although HIV is highly contagious, its own mortality rate is not high, nor is it the most powerful virus, nor is it terrible.

When it comes to what disease is more terrible than AIDS, it should be that this disease is more harmful to human beings than AIDS, and it cannot be simply said that this disease brings the suffering of individual patients. I think the plague, that is, the Black Death, should be far more harmful to human beings than AIDS.

There have been three pandemics in human history, the first led to the decline of an empire, the second caused great losses to European countries, and the third led to a worldwide epidemic. Say it briefly.

The first plague epidemic in history was confirmed in the 6th century AD, which claimed about 654.38 billion lives. The plague originated in the Middle East, then spread to the Near East and the Mediterranean, and lasted for 60 years. Plague claimed a large number of human lives and directly led to the decline of the Eastern Roman Empire.

The second world plague epidemic mainly occurred in Europe, from 1347 to 135 1. At that time, the plague was called the Black Death, and about 25 million people died from this disaster, accounting for one third of the whole population. It can be said that this is an epidemic and plague that brings great terror to mankind.

The third epidemic was particularly extensive, from19th century to 1950s, which was a worldwide plague epidemic. China's Yunnan has also unfortunately become the hardest hit.

Understand this, do you also think that plague is more terrible and harmful than AIDS?

Ebola virus, the virus spreads rapidly in the body, attacking various organs, making them denatured, necrotic and slowly decomposed. Due to the necrosis and decomposition of internal organs, patients constantly spit out necrotic tissue from their mouths, and finally died of massive internal bleeding, brain injury and other reasons.

You may spit out your anorectal structure from your mouth. When you are conscious, you will feel your organs slowly turning into paste. There is no cure for this disease. Patients usually die within 24 hours after onset.

Tetanus, in fact, tetanus is the role of Clostridium tetanus, not the role of the virus. But it's really pit. As an anaerobic bacteria, if you accidentally hurt yourself in a strange place, you may be infected. Northeasters insist that a little injury is all right. Most of them died of negligence. Suddenly, everyone was gone.

This can only be attributed to luck. After all, if you live in a place like Daxinganling, the medical system is completely empty talk to you. Even if he can't die, he will go through a lot of torture. According to everyone's different personality, different viruses have different degrees of fear of them.

Before our species evolved into a modern form, human beings have been fighting viruses. For some viral diseases, vaccines and antiviral drugs enable us to stop the widespread spread of infection and help patients recover.

However, with the destruction of Ebola in West Africa, we still have a long way to go to defeat the virus.

At present, the popular virus Ebola virus has killed up to 90% of infected people and is the most deadly member of the Ebola virus family. "The situation can't get any worse," said Elk Muberg, an Ebola expert and an associate professor of microbiology at Boston University.

However, there are other viruses that are equally deadly or even more deadly. The following are the nine most serious virus killers:

Marburg virus

Scientists discovered Marburg virus in 1967, when laboratory workers in Germany came into contact with infected monkeys imported from Uganda, resulting in a small-scale epidemic. Marburg virus is similar to Ebola virus, both of which can cause hemorrhagic fever, which means that infected people will have high fever and systemic bleeding, which will lead to shock, organ failure and death.

According to the data of the World Health Organization, the mortality rate of the first outbreak was 25%, but in the Congo outbreak in 1998-2000 and the Angola outbreak in 2005, the mortality rate exceeded 80%.

Ebola virus

From 65438 to 0976, the first known Ebola outbreak broke out in Sudan and Congo. Ebola virus spreads through contact with blood or other body fluids or infected human or animal tissues.

Ebola virus Reston is a virus strain that doesn't even make people sick. However, according to the data of the World Health Organization, the mortality rate of Bundibuji strain is as high as 50%, while that of Sudan strain is as high as 7 1%.

According to WHO, the epidemic in West Africa started in the beginning of 20 14, which is the largest and most complicated epidemic of the disease so far.

rabies

Although the rabies pet vaccine used in 1960s and 1990s has made this disease extremely rare in developed countries, it is still a serious problem in India and parts of Africa.

Experts said: "It destroys the brain, which is a very, very bad disease. We have anti-rabies vaccine and anti-rabies antibody, so if someone is bitten by rabies, we can treat this person. "

However, if untreated, the death rate of rabies is 100%.

AIDS

In the modern world, the deadliest virus is probably HIV. "It's still the biggest killer," said Dr Amish Adal Gaya, an infectious disease doctor and spokesman for the American Society of Infectious Diseases.

Since the disease was first diagnosed in the early 1980s, it is estimated that 36 million people have died of HIV. "Adal said that infectious diseases have the greatest impact on human beings.

Powerful antiviral drugs make it possible for HIV carriers to survive for several years. However, the disease continues to destroy many low-income and middle-income countries, with 95% of new HIV infections. According to WHO statistics, nearly 65,438+0 adults in sub-Saharan Africa are HIV-positive.

smallpox

1980, the World Health Assembly declared that there was no smallpox in the world. But before that, human beings struggled with smallpox for thousands of years, and the disease killed about one-third of smallpox infected people. It left a deep and permanent scar on the survivors, who were often blind.

The mortality rate of people outside Europe is much higher, and people rarely come into contact with the virus before bringing it to their region. For example, historians estimate that 90% of Native Americans died of smallpox introduced by European explorers. In the 20th century alone, smallpox killed 300 million people.

Adal Jia said: "This is a huge burden for the earth, not only death, but also blindness, which is the reason for eradication from the earth."

Hantaan virus

flu

According to the data of the World Health Organization, in the typical flu season, as many as 500,000 people around the world will die from this disease. But sometimes, when a new influenza virus strain appears, it will lead to an epidemic, the disease spreads faster and the mortality rate is usually higher.

The deadliest epidemic of influenza (sometimes called Spanish influenza) started at 19 18, which sickened as many as 40% of the world population and killed an estimated 50 million people.

dengue

Dengue virus first appeared in the Philippines and Thailand in the 1950 s, and then spread to tropical and subtropical regions around the world. At present, as many as 40% of the world's population lives in areas where dengue fever is prevalent. With global warming, the disease and mosquitoes carrying it may spread further.

According to the statistics of the World Health Organization, 5 to 6,543.8 billion people are infected with dengue fever every year. Although the death rate of dengue fever is lower than that of other viruses, which is 2.5%, it can cause diseases similar to Ebola, called dengue hemorrhagic fever. If it is not treated, the death rate of the disease will be 20%.

Rotavirus

There are two kinds of vaccines to protect children from rotavirus infection, and rotavirus infection is the main cause of severe diarrhea in infants. The virus can spread rapidly through what researchers call the fecal-oral route.

The World Health Organization estimates that in 2008, 453,000 children under the age of 5 died of rotavirus infection worldwide. However, countries that have been vaccinated have reported a significant decline in rotavirus hospitalizations and deaths.
