we will add symbols, add more, more rash, more, where so much? do not be sorry! up to 140 is still far away. a couple of shovels and a handful, but when will they run out
I can assure you that the Ebola virus has a very interesting history. This species belongs to the filovirus family, initially it was carried by animals, and more specifically - bats, like many other pathogens, including the human immunodeficiency virus, the SARS virus, Vibrio cholerae and many others, the Ebola filovirus has gone from a classic zoonotic infection (affecting only animals) to an anthroponous one, i.e. striking a person too. The interspecies transfer of microbes from animals to humans and vice versa has marked not the first millennium, it all began a long time ago, when we began to domesticate animals. We got tuberculosis and measles from cows, whooping cough from pigs, and flu from ducks. But it happened a long time ago, but the emergence of the Ebola haemorrhagic fever virus is a new phenomenon for us, we can say the “birth” of a new pathogen before our eyes, as it was with HIV in the 70s.
It's all to blame for progress and the restless craving of people for power; in the 1990s, the Guinean forests succumbed to systematic destruction. The rebels waged war with the armed forces of Sierra Leone and Liberia, felling timber for sale in order to find funds for military needs. Refugees moved into these forests, trying to escape from constant raids, robberies and terror both by the rebels and by the united armed forces. Until now, a virgin forest with a developed ecosystem was thinning before our eyes, many species either disappeared or took refuge where in other places, trying in vain to survive. But among the rest were, oddly enough, bats, they are very tenacious, multiply quickly and are not particularly picky about food. For all that, being also inherently excellent incubators for various kinds of infections.
As the settlements of humans and bats approached, new forms of interspecific contact appeared, they hunted mice, they themselves flew to feast on the fruits of fruit-bearing trees, leaving behind saliva and excrement containing various pathogens, including the Ebola virus.
And so, at some point, bat filovirus began to spread to humans. In humans, it caused hemorrhagic fever, which led to death in 50-90% of cases, depending on the specific region, virus strain, virulence and pathogenicity. At the moment, neither a treatment nor a more or less complete vaccine has yet been developed, and since the risk of a pandemic is minimal, there are no active developments either.
In the 2000s, the military conflict subsided. in those regions from which it was impossible to get out and not to get outside, new people began to arrive. Doctors without borders, various humanitarian organizations and others like them, which in turn gave the virus, which has already become anthroponous, new ways to spread.
This is how the epidemic began, which fortunately did not go beyond the region, but still less, at the end of 2015, which killed more than 10 thousand people.
If you are interested in reading about such microorganisms, very muchI advise you to pay attention to the work of science journalist Sonya Shah, in particular to her book "Pandemic".
