Top Ten Deadly Diseases Transmitted from Animals

Tuesday, 23 January 2018

Determining the origin of the disease is a very important part of effective treatment. In the world there are many diseases, the origin of which is still unknown. However, there are such deadly diseases that are transmitted to us from animals. They spread from one species to another. Unfortunately, one of these species is a person. So, below is a list of ten deadly diseases transmitted from animals to man.






10.  HIV infection (AIDS)

Top Ten Deadly Diseases Transmitted from Animals


Carrier: chimpanzee



It is believed that HIV infection originated in tropical Africa in monkeys (chimpanzees) and was transmitted to people at the beginning of the 20th century. The theory says that a hunter killed a chimpanzee, a carrier of the virus. And while cutting the animal, he cut himself (or he already had an open wound), through this wound the virus was transmitted to the person.

9.  Ebola Virus

Top Ten Deadly Diseases Transmitted from Animals


Carrier: African fruit bats

The natural focus of the Ebola virus is most likely located in the humid forests of Africa, and probably also in the Western Pacific. The sources of infection are bats of such species: Hypsignathus monstrosus, Epomops franqueti and Myonycteris torquata and, possibly, small terrestrial rodents. Experimental infections of bats did not lead to their death, which gave grounds to suspect them as the main sources of infection.


Côte d'Ivoire, the Republic of the Congo and Gabon have documented cases of human infection with the Ebola virus due to exposure to infected chimpanzees, forest antelopes, gorillas, porcupines, both live and dead. However, monkeys, antelopes, porcupines, is not the primary source of infection in nature, but is accidental, as they, like people, develop an acute disease, often with a fatal outcome.


8.  African Trypanosomiasis

Carrier: Ciesce fly

African trypanosomiasis is also known as "sleeping sickness" - a disease of animals and humans. Its cause is a parasite, a species of Trypanosoma brucei living in the blood, and a carrier of the Tsetse fly. These dangerous insects live mainly in tropical forests of subequatorial and equatorial Africa. At risk is approximately 70 million people in 36 different countries. WHO estimates that sleeping sickness affects 30,000 people annually.


7.  Severe Acute Respiratory Syndrome

Transporter: Chinese bat "red horseshoe"

Severe acute respiratory syndrome is also known as SARS, atypical pneumonia is a viral infectious disease that affects the respiratory system and is capable of dangerous epidemic spread. Sources of infection were predatory mammals from the family of viverroves and some bats. However, a study conducted in 2013 showed that it is bats that are the natural sources of the emergence of TGRS.


6.  Virus Nipa

Top Ten Deadly Diseases Transmitted from Animals


Carrier: Australian Flying Foxes

The NIP virus is a virus that causes a disease characterized by brain inflammation (encephalitis) or respiratory diseases. It was first discovered in September 1994, in a suburb of Brisbane in Queensland, Australia, when he led to the death of thirteen horses and their coach. It was found that the natural carriers of the virus are the carnivorous "Flying Foxes" (flying dogs), since there was no obvious disease among the fruiting vermin.


5.  Haemorrhagic fever Crimea-Congo

Top Ten Deadly Diseases Transmitted from Animals


Carrier: Hyalomma mite

Crimean-Congo haemorrhagic fever is a widespread (especially in East and West Africa) virus disease with a death rate of 30%. As a rule, it is transmitted by the bite of a hideous parasite - Hyalomma mite. Opened in 1945 by MP Chumakov on the Crimean peninsula, when examining the blood of sick soldiers and migrants who fell ill while performing hay harvesting.


4.  Bolivian Hemorrhagic Fever

Top Ten Deadly Diseases Transmitted from Animals


Carrier: field mice

Bolivian hemorrhagic fever or the virus of Machupo is an infectious disease, the mortality rate is 30%. It is considered a "sister" of the Ebola virus. It was first discovered in 1963 in the village of San Joachim in Bolivia (hence the name) by a research group led by Karl Johnson.


3.  Marburg Haemorrhagic Fever

Top Ten Deadly Diseases Transmitted from Animals


Carrier: African fruit bats

Marburg haemorrhagic fever or Marburg disease is a serious disease, a person and primates characterized by high lethality (according to data from various sources 50-90%) and severe course. Clinical symptoms are indistinguishable from Ebola virus. It is endemic in arid forest regions of equatorial Africa. Most cases of the disease are associated with people visiting caves or mines. Most likely, the natural carriers of the virus are fruit bats, which in many areas of the susceptible to Marburg disease are considered something of a delicacy. However, African green monkeys, whose reservoirs of infectious agents have not yet been found, are not excluded. Given the wide distribution of the African fruit bat population, the risk of a significant outbreak of Marburg disease is quite high.


2.  Lassa Fever

Top Ten Deadly Diseases Transmitted from Animals


Carrier: Multi-nosed rat

Lassa fever is an acute infectious disease, first discovered in 1969 in Lassa, Nigeria. Outbreaks of Lassa fever were noted in Nigeria, Liberia, Sierra Leone and Guinea. It is so prevalent in West Africa that its epidemics occur on an annual basis, infecting 300 000-500 000 people, of which about 5000 die. Given the high incidence, Lassa fever is considered the main problem in the African region. Probably, it is transmitted by contact with feces or urine of its natural carrier - the tadpole rat. The causative agent of this disease is one of the most dangerous viruses for humans - the virus Lassa.

1.  MERS

Carrier: Grave baggy sack

MERS or EMC / 2012 is a relatively new deadly disease found in Saudi Arabia in 2012. The natural carrier of the disease is Gravestone, but studies have shown that the virus does not spread through direct contact, but through an intermediate carrier. Scientists tested several different animals, and it turned out that some animals - camels, sheep, goats, cats can, are intermediate carriers through which people acquire MERS. As of June 2014, cases have been reported in 22 countries, including Saudi Arabia, Malaysia, Egypt, the United Arab Emirates, Turkey, Austria, the United Kingdom, the United States, etc. Almost all cases are linked in one way or another with Saudi Arabia.
