Coronavirus
Intruduction
The Coronaviruses are a family of viruses that were discovered on the in the 60 s,
but we don´t know the origin. The differents types cause different diseases, from a
common cold to an infection in the respiratory system. They infect both animals
and people. Most Coronaviruses aren´t dangerous and they have a treatment. and
most people get some kind of coronavirus at some point in their life.
Which is Covid- 19
The official name of this virus is SARS- CoV- 2 , Covid- 19 is the name of the
disease it causes which stands for Coronavirus disease 2019, Corona, as in
Crown, the virus is named for its crown- like spikes. It spreads through droplets
when we sneeze, cough or speak, and can enter us directly trough our eyes, nose
or mouth. The virus can also live on a lot of surfaces for hours, so people can pick
it up on their hands and infect themselves if they touch their face something the
average person does 20 times an hour. You can be infected and spread it withaot
any symptoms, or they can be mistaken for the flu. That´s what makes this
coronavirus so devious.
Origin of Covid-19
A group called EcoHealth Alliance has been coming to a cave in southem china,
catching bats, scanning them for viruses and flagging the ones that could most
easily make the leap to us. They have found a lot so far including hundreds of
coronaviruses. And they label them as high or low risk, depending how similar they
are to viruses that already infect humans. And a few years ago, they discovered
one that they called bat coronavirus RaTG13 wich met the criteria for low risk.
When scientist sequenced the genome of the virus behind COVID 19, they found
that 96% of it was identical to that bat virus. So, scientist believe that bat virus
evolved into this new virus that could infect humans. Scientist believe this one may
have mutated in another bat or it may have jumped to another species before
jumping to us, like a pangolin, a snake, or a fish.
