Bubonic plague

“Plague” doctors during the epidemic wore masks with long noses, which contained a vinegar-soaked swab

A terrible infection that hit the Middle Agesmost of the European population was defeated in the early twentieth century with plague vaccines, serums and antibiotics. Be that as it may, even in the twenty-first century, about 2,500 people a year become infected with this disease. Manifesting in the form of abscesses in the area of ​​axillary and inguinal lymph nodes, as well as in the form of fever, fever and delusional conditions. The disease is treatable in the early stages, but with the so-called septic form, the death rate from the plague even today exceeds 90%. Are we not that far gone from the Middle Ages?

Lymph nodes - These are the main organs of the human lymphatic system. A clear fluid called lymph flows through it, which is necessary for proper metabolism and the purification of cells and tissues.

anthrax

Anthrax that hit a cow

One of the most dangerous infectious diseases.anthrax can rightfully be considered, the development of which is facilitated by the bacteria Bacillus antracis. Featuring an incredible level of contagiousness, anthrax can remain on surfaces for decades, entering the human body through the gastrointestinal tract or by airborne droplets. Infection causes the appearance of necrotic ulcers, which, if untreated, are exacerbated by the transition of the disease to the pulmonary form of the disease. Mortality with such a sad outcome reaches more than 90% of the number of cases.

Contagiousness - This is the ability of infectious diseases to be transmitted from infected people and animals to healthy organisms through physical contact and other factors.

Cholera

Children often become victims of cholera

Being one of the “oldest” infections, choleraoften mentioned in the books of medieval writers whose real or fictional characters suffer from vomiting, seizures and severe dehydration, which, in fact, causes the death of the sick. Currently, the island of Haiti is considered the main location of the infection, where in 2010 one of the deadliest epidemics of the planet occurred. Then, according to official figures, the infection affected more than 200,000 people, of which 3,000 died. Although with timely treatment, mortality from cholera is quite low, without the use of antibiotics, up to 85% of all infected become at risk of death.

Rabies

Rabies is one of the most dangerous infectious diseases in the world.

Rabies virus can cause rabiesto enter the human body through saliva during a bite of a wild animal. At first, manifested in the form of fever, itching and pain at the site of a bite, the disease gradually progresses and causes the patient to give up water, to be scared of any sharp noise, to experience hallucinations and violent attacks. A few days after the acute form, the patient runs the risk of dying from respiratory failure and paralysis. Although rabies can be treated with a number of timely procedures, even with the onset of the first symptoms of the disease, rabies does not respond to any treatment and recovery in this case becomes impossible.

Even cows get rabies. Recently, scientists have discovered the causes of this terrible disease

HIV

HIV infection has become a real epidemic of the twentieth century

Describing the most dangerous infectious diseasesplanet, we could not help but mention HIV - the human immunodeficiency virus. Having appeared relatively recently, a dangerous infection spread very quickly around the world. According to World Health Organization estimates for 2018, more than 37.9 million people with HIV infection live on our planet. If previously the disease was transmitted from person to person through blood or sperm, as the epidemic increased, cases began to appear more often when people became infected during a blood transfusion, during childbirth, or even during unskilled medical examinations. Over the course of the existence of HIV, more than 30 million people have already died, and modern medicine could offer only supportive therapy to the sick for a long time. Be that as it may, in one of our articles we already wrote that several people who were previously recognized as HIV-positive were able to successfully recover from this extremely dangerous disease. You can read more about these amazing cases in this article.

Ebola Fever

Ebola fever is still considered almost a hoax

Ebola fever, in 2015, was heard atinhabitants of the entire planet, originated in West Africa and spread almost to the entire black continent. It is believed that dangerous fever manifests itself in persistent headache, pain in the abdomen and muscles, as well as heavy bleeding. A person could get such an unpleasant disease from carrier animals, which are considered monkeys, bats and rats. Due to the extremely high level of contagiousness, even one Ebola patient is a huge danger to his environment, which, according to WHO, has already led to the deaths of 22,630 people worldwide. Fortunately, a vaccine is currently being developed to cure such a dangerous infectious disease. You can read about its creation directly in this article.
