First of all, I hope that all human beings in the world are in good health and free from disease. AIDS is a disease that infects more humans and is difficult to treat. Is there a virus that is more terrible than it? What is scary is that there are indeed, some viruses are more terrible than HIV, and some viruses and The harm of HIV is almost the same, and I will briefly introduce it below.
1. HIV is a virus that causes defects in the human immune system. It was first discovered in the United States in 1981 to originate from chimpanzees and gorillas.
After being infected with HIV, the immune function of the patient is severely impaired. The patient is often severely infected by bacteria and viruses, which mainly cause interstitial pneumonia and acute encephalitis.
The horrible thing about AIDS is that after treatment, AIDS carriers who stopped treatment often reappeared with HIV. The virus is stubborn and cannot be eradicated. The average life expectancy after the onset of AIDS is 5.8-8.8 years.
AIDS has a long incubation period and a high mortality rate. 30 million people have been infected with HIV and nearly 12 million have died.
Because of the long incubation period, people living with AIDS generally do not know that they have been infected, or conceal their condition after learning of the infection, causing the invisible spread of AIDS. This is difficult to control.
Vaccine situation: A medical trial conducted in Thailand in 2009 showed that experimental vaccines can reduce the risk of AIDS infection and have certain immune effects.
2. The Ebola virus belongs to the Celloviridae family and is a highly contagious virus with a high fatality rate, which can be fatal within 24 hours. The biosafety level of Ebola virus is four higher than that of AIDS and SARS, and it is a virus that requires a higher level of protection than AIDS and SARS. Human infections originate from orangutans that died in the wild.
The incubation period of Ebola virus is 2 to 21 days, usually 5 to 10 days.
Ebola virus mainly attacks various organs, deforms, necroses and chronically decomposes the organs, causing internal hemorrhage, brain damage and death. The fatality rate is very high, ranging from 50% to 90%. The causes of death are stroke, myocardial infarction, hemorrhagic shock, organ failure, etc.
The most frightening thing about Ebola is that it is highly contagious. Route of transmission: The patient's body fluids directly contact the skin and mucous membranes, etc. Contact infection, close contacts or even sleeping in the same room may be infected, the infection rate is about 23%.
Vaccine situation: In 2014, the first Ebola vaccine from the National Institutes of Health of the United States passed clinical trials. At the end of 2016, the Public Health Agency of Canada developed a vaccine to achieve high-efficiency protection against Ebola virus. In 2017, China Food and Drug Administration approved "recombinant Ebola". Virus vaccine".
Ebola virus is mainly intermittently circulating in African countries. Although it is highly contagious and has a high fatality rate, it only spreads locally.
3. The SARS virus was once popular in China in 2003, and many people still have deep memories. High infectivity, acute onset after infection, and fatal.
SARS is a severe acute respiratory syndrome caused by a coronavirus. Spread through the respiratory tract or contact with the secretions of the patient's respiratory tract.
symptoms are fever, headache, muscle aches, respiratory failure
The incubation period is 1 to 16 days, usually 3 to 5 days.
Isolation and prevention are very important. During the epidemic, there are special fever clinics in hospitals, and the body temperature is tested at airports and railway stations when traveling.
Vaccine situation: There is currently no vaccine.
4. The plague is also called the Black Death. It is a severe infectious disease. It is spread by rats and fleas. It has been epidemic on a large scale in history. About 25 million people died during the epidemic in Europe in the 14th century. The rate is relatively high and difficult to control.
Symptoms are mainly chills, high fever, headache, skin ecchymosis, bleeding, lymphadenopathy, and pneumonia bleeding.
is divided into lung type and gland type.
The route of infection is through respiratory droplets, rat and flea bites, skin infections (skin damage), digestive tract infections (eating virus-infected meat), and the lung type is mainly airborne.
The incubation period is 2 to 8 days, and the onset is rapid.
Vaccine situation: There is a plague vaccine, which needs to be vaccinated once a year, and if necessary, vaccinated again in six months. However, the vaccine cannot prevent 100%, and there is a possibility of the onset. The onset is delayed compared with those who have not been vaccinated, and the onset is about 9-12 days.
These types of viruses are relatively serious threats to humans. Some viruses spread invisibly, while others spread quickly. It is hoped that medical researchers can develop therapeutic drugs and effective preventive vaccines so that these viruses no longer pose a deadly threat to humans. .

Let us first understand the horror of AIDS.
AIDS is a chronic and incurable disease that requires treatment for life. There is currently no drug that can completely cure HIV. It mainly destroys the human immune system, leading to defects and reduction of the human immune system. This is the most terrible thing that can cause other diseases. Compared with other viruses, AIDS is still not the most terrifying, such as the new coronavirus that swept the world in the winter of 2019, and the Ebola virus and plague in Africa, which are the most terrifying viruses.
1. New Coronavirus
For the Chinese people, the new crown virus is no stranger to it. 2020 has swept the world, and it has not yet been cured. The new coronavirus is an unprecedented coronavirus, which is highly infectious and highly concealed. The new coronavirus is more infectious than the SARS virus.
2, Ebola virus
Ebola virus is an acute infectious disease. Ebola virus is a severe infectious disease virus that can cause humans and primates to produce Ebola hemorrhagic fever. Ebola hemorrhagic fever is the most deadly hemorrhagic fever in the world. The main symptoms are fever, vomiting, diarrhea, hypotension, bleeding and so on. It is extremely contagious, and it is transmitted from person to person and from person to person. The mortality rate is as high as 90%, and the main causes of death are stroke, myocardial infarction, shock and organ failure.
3, flu
The Spanish flu caused 100 million deaths in the world, the worst in the world, and it is extremely contagious.
There is also the smallpox virus, but it was overcome by humans in the world.

Is there a virus more terrible than HIV in the world? First of all, to answer this question, I need to understand how fearful HIV exists. Now I will tell you the horror of HIV: HIV is not directly fatal, it is fatal. A weakened immune system caused by infection with a virus. Therefore, HIV is not too scary compared to the direct lethality of many viruses, but it is scary because it destroys the immune system, a mechanism that is very different from other viruses. Here are some deadly viruses that still exist in the world that may be considered more terrible than HIV.
The first type: herpes B virus (80% mortality) The herpes B virus is highly harmful, with a case fatality rate of 80%. Rhesus herpes virus B virus is a simple virus that infects rhesus monkeys and spreads from one host to another through peripheral nerve infection. The virus affects the central nervous system and can cause neurasthenia or death if left untreated. Some important symptoms of viral infection include shortness of breath, muscle coordination, and fever. This is a terrible virus.
The second kind: rabies virus (100% mortality) Rabies virus is a neurovirus that causes rabies in humans. The virus is spread through animal saliva or human body fluids. Nearly 55,000 people die of rabies every year. Zoonotic diseases are spread through animals such as cats, bats, dogs, monkeys and mongooses. 100% lethal, the virus is fatal because it directly affects the brain and nervous system of humans and animals. Symptoms of viral infection can range from hydrophobia 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 still tremble now)
The third type: smallpox virus, has been extinct, as for how terrible it is, I don’t need to say
