According to experts, corona can probably be traced back to animals.
There are also many other diseases that can be transmitted from animals to humans.
An overview.
Corona
was presumably
transmitted
from
animals
to humans.
Other
diseases
are also of animal origin.
The best known are the
plague
and
malaria
.
Kassel - The
corona pandemic
restricts the social and public life of many people.
According to
scientists,
the
coronavirus
is probably due to an animal origin.
According to the current state of knowledge, most scientists assume that the transmission of
corona
took place through bats.
This was announced by the Westdeutscher Rundfunk's online news and knowledge portal “quarks.de”.
However, this has not yet been clearly proven.
Corona infections from October 26th, 2020 (source: RKI) | 437,866 (+8,685) |
|---|---|
Deaths | 10,056 (+24) |
7-day incidence \ t | 80.9 |
Corona did not originate from animals on market in Wuhan
According to "rnd.de",
however
,
Corona
should
not have originated in a market in Wuhan, but has existed for a while.
Previously, the virus is said to have only attacked bats.
According to experts, it is unlikely to develop in the laboratory, as the genetic material of the
coronavirus
does not show any artificial manipulation.
A disease that is
transmitted
from
animals
to humans is called
zoonosis
.
And there are quite a few of them.
Zoonosis can be transmitted through contact with an infected animal or animal products such as milk or meat.
The hosts do not cause the disease themselves, but are only the carrier.
As “br24.de” reported, almost 70 percent of all infectious diseases are zoonoses.
Pathogens can be bacteria, viruses and fungi.

Like Corona: There is still no vaccine for malaria
The Black Death particularly raged in Europe between 1346 and 1353: the
plague
.
The disease claimed an estimated 25 million deaths - at that time a third of the population.
The disease was transmitted to humans by rat fleas.
Plague bacteria still exist today.
However, the disease can now be treated with antibiotics.
With around 200 million illnesses each year,
malaria
is the most common infectious disease.
Similar to
Corona
, there is still insufficient protection here - there is still no vaccination.
Malaria is also
transmitted
from
animals
to humans, namely through the anopheles mosquito.
According to "rtl.de", more than 400,000 people died of the disease in 2018.
Children are particularly at risk.
Flu viruses like Corona can be attributed to animals
Many flu viruses can be traced back to Asia and also originate from
animals
.
In the case of
bird flu
(scientific name: H5N1), wild water birds first transmitted the virus to other bird species - then to humans.
Although transmission from
animals
to humans is rare, the disease is often fatal.
The
swine flu
(H1N1) or New flu can be attributed to an animal origin.
The pandemic broke out in 2009, killing 18,449.
Already in 1918/19 a similar H1N1 virus caused an influenza pandemic (Spanish flu).
It claimed the lives of 20 to 50 million people.
Unknown coronavirus transmitted by animal
The list of
zoonoses
is long.
Similar to
Corona
, the severe acute respiratory syndrome (SARS) is an infectious disease - now SARS-CoV-1.
The pathogen was first observed in China in 2002 and was previously considered an unknown
coronavirus
.
Experts believe that the virus was transmitted to humans from crawling cats.
Ebola
made it from bats to humans in West Africa;
HIV
was transmitted by a species of monkey.
Rabies
is also known in this country and is transmitted through the bite of an animal with
rabies
, such as a fox or a dog.
The rabies virus causes meningitis, which is
almost always fatal
, in
animals
.

Like Corona: Toxoplasmosis transmitted by animals
The infectious disease
toxoplasmosis
mainly affects cats.
After an illness, they usually remain immune for the rest of their lives.
When transmitted to humans, the infection is usually mild.
However, if a pregnant woman becomes ill for the first time, this can lead to considerable damage to the unborn child.
Cows also transmitted diseases such as
measles
or
brucellosis
.
Transmission of
tuberculosis
through infected milk is also possible, but now it is rather rare.
Like Corona: Experts warn - more diseases from animal to human
Researchers warn that in the future more and more diseases will
jump
from
animals
to humans, similar to the
coronavirus
.
"If we continue to exploit the wildlife and destroy our ecosystems, we can expect a steady stream of these diseases, which are transmitted from animals to humans, in the coming years," warned Inger Andersen, head of the United Nations Environment Program, in a report dated July 6th .2020.
An international virus research initiative, the Global Virome Project, estimates that there are around 1.6 million viruses in the
animal world
.
Of these, 600,000 to 800,000 are said to be transferable to humans.
However, this does not mean that infected people automatically fall ill, according to "quarks.de".
Some viruses have no effect on humans.
