Top 10 most dangerous viruses for people. Deadly nine: the worst infections in the world

The human species constantly interacts with living nature. Today's thoughts about the world are the same - viruses appeared long before the creation of the DNA molecule. The underlying hypothesis is that the bacterium is an evolutionary result of degenerative unicellular cells, a derivative of an ancient pre-clinical form of life. The intense struggle of mankind against unknown types of viruses leads to the formation of worms - they mutate, develop and adhere to the minds that we create, in which we take an active part in the evolutionary formation of the genetic material of all living organisms. Soon, great pandemics are taking hundreds of lives.
We present to you the top 10 most dangerous viruses that people have seen since ancient times.

Human immunodeficiency virus (HIV)

The deadly virus rightfully takes first place in the world rating. As of today, there are no drugs available for SNID treatment. You can only protect yourself from infection through additional effective prevention.

The first episodes of SID were recorded in the 1930s in one of the western African regions. It was believed that the carrier of the virus was mapi. Official observation and laboratory investigation of the disease were carried out in 1980 to identify 440 US residents.
The human immunodeficiency virus destroys the disease system by damaging CD4 lymphocytes (clin, which is responsible for reducing pathogenic infection), a decrease in the number of which leads to a change in organ function Removal of excessive pathogenic microflora.
Jerel infection is a latent nose and illness of a person. Infection is acquired through blood and biological evidence - human contact of all types, blood transfusion, pregnancy, breastfeeding, injections, organ transplantation, personal microtrauma.
The incubation period is troubling, from the moment the pathogen penetrates the body until symptoms appear, it takes a lot of time - or more.

The average life of a VIL-infected person is a little more than 11-15 years.

Vidoma stages of VIL

Garyachkova – appears in 50% of infected people, characterized by minor intestinal and cold symptoms (body aches, diarrhea, boredom, rarely a sore throat);
asymptomatic – duration up to 10 days. The virus destroys the immune system. It is very rare that small lesions appear in the area of the lymph nodes;
development of SNID. Activation of latent pathogenic organisms found in humans. The appearance of a white ooze, hemorrhagic viscosity, sweating, decreased vision, and a sharp decrease in fat mass to 10%. Then the body becomes susceptible to hyperthermia, diarrhea, lymphoma, tuberculosis and Kaposi's sarcoma.
The troubles of life for a patient with HIV/AIDS with progressive symptoms are no more than two fates.
Treatment is carried out with immune-stimulating, antiviral and antibacterial drugs in hospital hospitals. The mainstay of meta-drug therapy is prolongation of infected life.

Fundamental methods of effective prevention of HIV infection

1. Use a condom, one sexual partner.
2. Do not use other people’s hygiene items.
3. For personal manipulation, use a disposable instrument.

I'll tell you the virus

This is a very dangerous virus in the world for people. The illness comes from ancient times. An effective method of combating illness is immediate revaccination immediately after infection. The heaviest cases of infection occurred in Asia, Africa, Canada, and the USA (the first episodes of infection in humans since 1880).
Zbudnik - Rabies virus, is transmitted through the bite of a domestic or wild animal. Having penetrated the body, the virus ruins the central nervous system, causing meningoencephalitis, asphyxia and heart failure, resulting in respiratory paralysis.

Creatures are infected with Jerel - dogs, cats, foxes, raccoons, rodents. People can become infected with the vaccine during the incubation period.
The process of development of the disease takes 10 days before death in people (usually 1-4 months), in animals - up to 2-3 days. If the bite does not develop within the first 10 days after the bite, the probability of death for humans becomes 99% (everyone in the world has only 3 episodes of fatigue after the active phase).

Symptoms I'll tell you

Symptoms of progressive illness are characterized by periods:

1. Early – subfebrile body temperature, restless (1-3 days).
2. Rozpal - aggression, hallucinations, madder, fear of water (up to 4 days).
3. Paralysis - the state of a living corpse, strength, severity of reactions, paralysis of ends, poisoning (up to 8 days).
Treatment of a patient during the period of active symptoms is ineffective - medical care is taken to alternate symptomatic treatments until the infected person becomes relieved.

Preventative visits to tell you what to get used to

Proper vaccination of your animals;
please contact us for medical help for bites from stray dogs, cats or wild creatures;
completing a full course of conservative therapy immediately after the bite.

Ebola virus (hemorrhagic fever)

This is called a dangerous, highly contagious virus for humans, the origin of which is the Zaire ebolavirus. First identified in 1976, during an epidemic in Zaira, which covered most of the Ebola River basin (maybe 90% of deaths).
It has been established that the carriers of the virus are rodents, kazan and mawpi.
Current epidemics caused by mutation species of the virus:
town of Nzara and Uganda (Sudan). In 1976, the mortality rate due to this virus was 54%, in 1979 - 53%, in 2000 - 53% of patients. Dzherelo infection was not detected;
Philippines, and then the USA. 1989 - hemorrhagic fever in the middle of the war;
forest Tai (Africa). 1994 - human infection through laboratory investigation of MAP corpses;
Bundibugio (Uganda). 2007 – the epidemic claimed 40 lives from 140 registered illnesses;
Kongo. 2012 river – 37% mortality rate.
Currently, the vaccine against the Ebola virus is undergoing testing at pharmaceutical companies, so there is no information about the availability of the anti-drug on the current market. The Ministry of Health has officially confirmed the approval of an experimental syrup to promote the popularization of the epidemic.
The illness is characterized by seasonal rashes and is recognized as a global threat to humanity.
Localization of the pathogen is important in the blood, mucus, and other visible areas of the infected (sperm, semen, mucus). Transmitted by contact, injective, state ways. Infection does not turn off when touching or touching dirty household items.
The period of development of the disease lasts 2-3 days. Having reached the body, the virus blocks the complement blood group (inactive proenzymes that bind to antigenic bodies to destroy and aglutinate the remaining ones).
The main signs of Ebola fever are hemorrhagic vomiting, fatigue, apathy, pain in the ridge and ends, pharyngitis, and rapid rise in temperature. Then diarrhea, abdominal pain, and disorientation appear. After a week, the active phase changes to increased pain, bleeding from the nose, lopsided delivery, dry cough and acute pancreatitis. On the 14th day of illness – infectious intoxication, hemorrhagic shock, heavy bleeding.
Positive dynamics in the treatment of sick patients with illness include convalescent plasma (noses that build up immunity after illness). However, the method does not guarantee perfect clothing. The estimated mortality rate for the Ebol virus is close to 50%.

Marburg virus (hemorrhagic fever)

A close relative of the hemorrhagic fever Ebola. 1967 - date of the first human infection with this virus, recorded in Marburzi (Nimeczina). The infected animals were mawpi from Uganda, who were brought for experiments.

The cause of the disease was identified as the zoonotic Filoviridae virus (which is transmitted between humans and animals). It is transmitted that the infection is caused by contact with biological environment (sleep, vomit, blood, sight).
Risk group for potential infection with Marburg virus
veterinarians who are in contact with mammoth animals from Africa;
ever since the virus is being traced;
healthcare workers who are in contact with patients with the Marburg virus;
laboratory workers who are involved in the investigation of biomaterials.
The period of propagation development (incubation) lasts no more than 10 days. Then the patient develops fever, pain in the flesh. Symptoms gradually worsen - they include sagging body, diarrhea, abdominal pain, diarrhea, pancreatitis, organic dysfunction, loss of vagina. The further development of liver failure, internal bleeding, madderness and hallucination is not excluded. The mortality rate ranges from 25 to 85%.

There is no vaccine against the Marburg virus.

Investigations into the contagiousness and growth of the virus began in 2014. Today, nanoparticles that may be involved in viral dereplication are being revealed and are being tested on viruses.
In our opinion, the only way to fight the virus is to avoid as many contacts as possible when coming into contact with African animals.

Virus rise (natural)

The common cold virus, which is dangerous for humans, is divided into two types: Variola Minor (chickenpox) and Magor (black fever). Epidemics of black outbreaks claim 40% to 90% of human lives; those who survive become disabled.

The first mystery about a fatal disease in the 4th century is the black outbreak epidemic in China (95% mortality rate). 6th century – disease affects the densely populated areas of Korea (88% of deaths). 737 rivers - the population of Japan decreased by 35% (black outbreak pandemic). In 1,500 years, the Black War took away millions of European lives. In the period from 1700 to 1800, the first siren was prepared and tested. Variolation (splitting) had the effect of reducing mortality by up to 10%.
Infection is caused by the drop-and-drop method, upon contact with the nose or illness. The incubation period does not exceed two days. Entering the lymph, the virus spreads throughout the epithelium, creating purulent pustules. Severe forms of the disease include hemorrhagic syndrome, encephalitis, infectious-toxic shock and death. The people who have been forking are removing painful scars from pustules all over their body. As a result of great hemorrhoids, those who see experience blindness.
Humans are infectious from the remaining five days of incubation until the pustules fall out.

The body of the dead from the black sore is contagious for up to several months.

Natural treatment is carried out with antiseptic and bacterial preparations, broad-spectrum antibiotics.
The black fever virus has been repeatedly recognized by humanity as a biological disease. As of today, daily data on the detection of the virus in natural climates are stored in the laboratory.

Spanish flu virus (Spanish flu) and influenza

The most dangerous virus in the world. At the end of the First World War, over 35% of the world's population was infected with the Spanish flu, and its mortality rate was close to 5% of the total population (150 million).
Zbudnik - H1N1 virus, visions from an investigated mummy in Alaska (XVIII-XIX centuries). Transmitted by the wind-dotted way. After the last hour of incubation (up to 4 days), the patient develops cyanosis of the skin, a sudden increase in body temperature up to 40 degrees, and coughing up blood. Then the rapid development of legen's bleeding. Death comes when it is drowned in its own blood.
The development of severe complications with fatal results in the first days of illness was especially important in patients with decreased immunity, with vaginity, in children under 14 years of age, and in elderly people.

Signs of infection

Characteristic signs of infection for patients from the risk group
1. Rapid development of hemorrhagic pneumonia (over a period of several years).
2. The disease affects only adults (from 25 to 45 years old).
3. The probability of death becomes 95% at the first risk of illness.

The massive pandemic of Spanish influenza during the First World War was recognized as a light catastrophe of a large-scale nature.

At the beginning, active vaccination of the population was carried out, infected patients were treated with antiviral drugs.
Today, the H1N1 virus has undergone modifications and is more easily overcome. When Spanish flu is detected, the lethal rate is no more than 2% (important among patients who are too late to seek medical help).

Dengue virus (bone-breaking fever and fennel disease)

A dangerous virus that is transmitted transmissibly (through coma bites). The location of localization is in the regions of Western and Western Asia, Africa, and the Caribbean. The incidence of illness reaches approximately 50 million people, and in the hemorrhagic form the fatality rate is up to 50%.
The origin of the Dengue virus in the mid-20th century was the Flavivirus virion (homeland of abroviruses Flaviviridae - antigenic group B).
Dzherel infection is a mawpi, a sick patient, rarely a kazhan. Please note that illnesses are spread by mosquitoes. The mosquito is contagious for the first three months after being bitten by an infected individual and can carry several serotypes of the virus. The period of development of the virus in the human body is up to seven days.
The main symptoms of the mild stage (primary infection - classic)
myasovy and kistkovy bil;
increased temperature up to 40 degrees;
heartbeat;
hyperemia of the eyeballs, throat;
sagging on the body, itching;
restless.
A more important form of the disease develops in the local population, and occurs with a single infection of a small population with different types of abrovirus.
Symptoms of hemorrhagic form of illness
increased lymphaticity, boredom, vomiting;
cough, weakness, abdominal pain;
development of pancreatitis, shunt bleeding;
cyanosis;
quickened heartbeat, vomiting blood.
Treatment of Dengue fever is carried out with calming methods and vitamins. In severe forms, use plasma therapy, coagulants, and glucocorticoids.

A second infection with the Dengue virus is not safe for a person, but first of all, the fragments of the body’s production of antibodies and the addition to the immune system make it easier to avoid re-infection.

Zika virus (Zika fever)

One of the varieties of dangerous viruses that are transmitted transmissively. Seen laboratory in the forest of Zik (Uganda) in 1947.
The first human infection was recorded in 1968 (Nigeria). From 1951 to 1982, serological tests of the virus were detected in India and Egypt. Since 2007, a similar popularization of the virus has been expected - New Caledonia, Great Britain and Cook Islands, Great Britain and Central America, Africa. In 2007, the disease was classified as a pandemic.
Zbudnik is a Flavivirus virus that causes the same type of illness. Dzherel is infected with Mavpi. The infection is transmitted in comas, and transmission through blood, natural sight, and environmental contact is also not excluded.
The incubation period lasts three times more than two days. The first signs of illness are a sagging body, fever, aches, pain in the corners, and swollen ends. Indicators of severe intoxication on a daily basis.
The current world still does not have specific liquids for treating viral infections. Sickness is not fatal, it occurs through the expression of the stages of neurotropism (it affects the nerves and neurons of the Stovburian cells). How the complexion calls for microcephaly.

Lassa Virus (Lassa Fever)

The infection is characterized by severe overload, damage to the respiratory organs, hemorrhagic lesions, and a high rate of death.
The disease is the Lassa mammarenavirus virus, officially recognized as one of the most dangerous for humans. Dzherel infection is schuri. The main localization is Western and Central Africa. The mechanism of transmission of the virus to humans is mainly fecal-oral (through food, water), aerosol and direct contact.
Lassa's disease with fever is even more contagious for those who are absent. Infection in humans is acquired through blood, natural contact and contact. In the presence of viral infections, medical personnel are exposed to instruments that are used for testing.
The period of development of illness ranges from six days to two or three days. The sick person senses sickness, loss of life, and sore throat. There is a gradual increase in mucous membranes (conjunctivitis) and increased lymph. 80% of patients show signs of viral necrotizing pharyngitis of the throat; Temperature changes are accompanied by diarrhea and vomiting. Another type of illness is characterized by visiping, hemorrhagic bleeding (nasal, uterine, pelvic, leg). A difficult ordeal is marked by severe bleeding and rapid development of blood loss and intoxication. The lethal result is high and lasts for 10-12 days of illness.
Treatment of patients for Lassa fever is carried out using antiviral drugs, antibiotics, and plasma injection is practiced in the early stages. In important stages of illness, the mortality rate drops to 55%.
Before the final preventive entry against infection with the Lassa virus, premises must be disinfected; quarantine entries arrived from localized regions.

Rotavirus (intestinal flu)

Due to the fact that 40% of the death rate is illness, we believe that people’s lives are not safe. Children under five years of age are at particular risk of infection.
Diary of illness - visions of 1943 fate virus Reoviridae. When it is absorbed into the body, it causes severe excretion and intoxication. The origin and development of illness is seasonal - the virus becomes active during the winter period.
Mid-term episodes of illness are most often recorded in nursing homes for elderly people and preschools. The most common rotavirus infection recorded in 2005 (Nicaragua – 30% mortality). According to research, it is transmitted that in the middle of the development of the rotavirus, the virus is transmitted through mutation to the virus. Previously, another person died of a middle-aged infection in Brazil (1977).
Dzherela is guilty of an unknown virus. People can become infected with ingested breast water through household items or through close contact with an infected nose. The period of development of symptoms of illness is up to 5 days.

Symptoms of rotavirus infection

1. First - on aphids, weakness and loss of strength, temperature rise to 40 degrees, vomiting, appearance of light yellow clay-like evaporation.
2. Secondary – signs of dehydration (loss of fluid) are observed, such as vomiting and occasional rare bowel movements, daily appetite, the undead and a sore throat, a dark cut.
Treatment is carried out in a comprehensive manner - immediate relief of dehydration symptoms, reduction of intoxication in the body, internal administration of radicin.
As a preventive measure against rotavirus infection, the situation is stagnant in countries with an insufficient level of medical care and obvious signs of unsanitary conditions.

The rating of the top 10 dangerous viruses on the planet is not residual. Which of them is the most unsafe is impossible to transfer. Today, new types of viruses are being discovered, their similarities and nature are being traced, and there is an attempt to understand how harmless they are for people.
However, regardless of the highest scientific achievements, the problem of human support for viruses is no longer relevant to this day. To save our population, it is necessary to constantly and actively combat fatal viral diseases. It is therefore important to know the etiology of the most aggressive biological microorganisms already known to mankind.

The computer virus spread throughout the email in the received file, and after the client opened the file, the virus spread to the first 50 addresses in the address book of the email program. Microsoft Outlook.

There is an idea that creatures, plants and people are more important in numbers on planet Earth. It's really not like that. The world is free of microorganisms (microbes). And viruses are among the most dangerous. The stench can become the cause of various illnesses for people and creatures. Below is a list of the ten most dangerous viruses for humans.

10. Hantaviruses

Hantaviruses are a class of viruses that are transmitted to humans through contact with rodents or their products. Hantaviruses cause a wide variety of illnesses, with such groups of illnesses as “hemorrhagic fever with neuropathy syndrome” (mortality rate averages 12%) and “hantavirus cardiopulmonary syndrome” (mortality rate up to 36%). The first great outbreak of illness, the outbreak of hantaviruses, and the outbreak of “Korean hemorrhagic fever” began during the Korean War (1950-1953). Then, over 3,000 American and Korean soldiers experienced an influx of a virus unknown at that time, which caused internal bleeding and impaired function of the nerves. It is worth noting that this virus itself is considered the most likely cause of the epidemic in the 16th century, which was blamed on the Aztec people.

9. Flu virus

The influenza virus is a virus that causes acute infection in people due to respiratory illnesses. At this hour it is sleeping more than 2 thousand. of its variants, which are classified into three serotypes A, B, C. The group of viruses with serotype A is divided into strains (H1N1, H2N2, H3N2, etc.) which are the most dangerous for humans and can lead to an epidemic and pandemic ї. Around the world, due to seasonal epidemics of influenza, the number of deaths from influenza ranges from 250 to 500 thousand. people (most of them are children younger than 2 years old and older people aged 65 years or older).

8. Virus Marburg

The Marburg virus is a dangerous virus of humans, beyond descriptions in 1967 during the time of small outbreaks in the German cities of Marburg and Frankfurt. In humans, there is hemorrhagic Marburg fever (mortality rate 23-50%), which is transmitted through blood, feces, mucus and vomit. The natural reservoir for this virus is sick people, most likely rodents and other species of mosquitoes. Symptoms in the early stages include fever, headache and pain in the stomach. In the later years - swelling, pancreatitis, vaginal loss, delirium and neuropsychiatric symptoms, bleeding, hypovolemic shock and multiple organs, most often the liver. Fever Marburg includes up to dozens of deadly diseases that have been transmitted to animals.

7. Rotavirus

Next on the list of the most dangerous viruses in humans is Rotavirus, a group of viruses that are the most common cause of acute diarrhea in young children. Transmitted by fecal-oral route. This illness can be easily cured, but in the world, more than 450,000 children are dying in the century before the age of five, most of whom live in the apologetic countries.

6. Ebola virus

Ebola virus is a group of viruses that causes Ebola hemorrhagic fever. It was first discovered in 1976 that an illness was dying near the Ebola River basin (the name given to the virus) near Zaire, DR Congo. It is transmitted through direct contact with the blood, sight, other bodies and organs of an infected person. Ebola fever is characterized by a rapid increase in body temperature, marked weakness, flesh and headaches, as well as a sore throat. Most often it is accompanied by vomiting, diarrhea, vomiting, impaired liver and liver function, and in some cases internal and external bleeding. According to data from the US Disease Control Center, in 2015, 30,939 people were infected with Ebola fever, of which 12,910 (42%) died.

5. Dengue virus

The dengue virus is one of the most dangerous viruses for humans, causing dengue fever in important forms, with a mortality rate of close to 50%. The illness is characterized by fever, intoxication, myalgia, arthralgia, fever and enlarged lymphatic nodes. It is widespread in the regions of Western and Western Asia, Africa, Oceania and the Caribbean, where approximately 50 million individuals are currently infected. Retailers of the virus cause illness in people, mice, mosquitoes and Kazan.

4. The virus has risen

The virus is a complex virus, the cause of a highly contagious disease that only infects people. One of the most recent illnesses, the symptoms of which are chills, pain in the face and sides, increased body temperature, confusion, headache, vomiting. The next day, wisps appear, which soon turn into rotten bulbs. In the 20th century, this virus took the lives of 300-500 million people. From 1967 to 1979, approximately 298 million US dollars were spent on the anti-revolution campaign (in 2010 the equivalent of 1.2 billion dollars was spent). Fortunately, the last episode of infection was registered on June 26, 1977 near the place of Somalia Mark.

3. I’ll tell you the virus

The virus is a dangerous virus that affects humans and warm-blooded creatures, which causes a specific effect on the central nervous system. This disease is transmitted through the nose through the bite of an infected animal. Accompanied by an increase in temperature to 37.2-37.3, bad sleep, illnesses become aggressive, violent, appear hallucinations, madness, a feeling of fear, paralysis of the eyes, lower ends, paralysis occurs. and discord, death and death. The first signs of illness appear late, as the brain has already developed destructive processes (swelling, hemorrhage, degradation of nerve cells), making it practically impossible to treat. To date, only three cases of infected people without vaccination have been recorded, all of which ended in death.

2. Lassa Virus

Lassa virus is a deadly virus that causes Lassa fever in humans and primates. The disease was first discovered in 1969 in the Nigerian town of Lassa. It is characterized by severe overload, damage to the respiratory organs, the central nervous system, myocarditis and hemorrhagic syndrome. It is particularly prevalent in the western African regions, especially in Sierra Leone, the Republic of Guinea, Nigeria and Liberia, where illness rates reach 300,000 to 500,000 per year. kiv, about 5 thousand. cause the patient to die. The natural reservoir of Lassa fever is the mammary beetle.

1. Human immunodeficiency virus

Human immunodeficiency virus (HIV) is the most harmless human virus, the cause of HIV infection/SNID, which is transmitted through direct contact of the mucous membranes and blood from the body of the patient. During the course of HIV infection in some people, new strains (varieties) of the virus, such as mutants, are formed, all of them differing in the speed of creation, inoculation and killing. and other types of cells. Without medical supplies, the average life of a person infected with the immunodeficiency virus becomes 9-11 years old. According to data for 2011, 60 million people fell ill with HIV infection in the entire hour, of which: 25 million died, and 35 million continue to live with the virus.
