Coronaviruses (CoV) are a family of viruses
that cause sicknesses like the common cold, as well as more severe diseases, such as Middle
East Respiratory Syndrome and Severe Acute Respiratory Syndrome. A novel coronavirus (nCoV) is a new strain
– one that hasn’t previously been recognized in humans. Coronaviruses cause diseases in mammals and
birds. A zoonotic virus is one that is transmitted
between animals and people. When a virus circulating in animal populations
infects people, this is termed a “spillover event”. It is speculated that the 2019 novel coronavirus,
or CoVid-19, originated in bats and was transmitted to humans, possibly with pangolins as an intermediate
host. Unfortunately, CoVid-19 is now spreading from
human to human as well. CoVID-19 has surpassed the SARS death toll
in a matter of weeks – even though the death rate is much lower, it spreads faster. Early data suggest that in around 82% of cases,
symptoms are relatively mild. The illness begins and ends in the lungs. However, the remainder of cases are severe
or critical, typically in older or immunocompromised individuals. How does CoVID-19 affect the body? The virus is fitted with protein spikes sticking
out of the envelope that forms the surface and houses a core of genetic material. Any virus that enters your body looks for
cells with compatible receptors – ones that allow it to invade the cell. Once they find the right cell, they enter
and use the cell’s replication machinery to create copies of themselves. It is likely that COVID-19 uses the same receptor
as SARS – found in both lungs and small intestines. It is thought that CoVID-19 shares many similarities
with SARS, which has three phases of attack: viral replication, hyper-reactivity of the
immune system, and finally pulmonary destruction. Early on in infection, the coronavirus invades
two types of cells in the lungs – mucus and cilia cells. Mucus keeps your lungs from drying out and
protects them from pathogens. Cilia beat the mucus towards the exterior
of your body, clearing debris – including viruses! – out of your lungs. Cilia cells were the preferred hosts of SARS-CoV,
and are likely the preferred hosts of the new coronavirus. When these cells die, they slough off into
your airways, filling them with debris and fluid. Symptoms include a fever, cough, and breathing
difficulties. Many of those infected get pneumonia in both
their lungs. Enter the immune system. Immune cells recognize the virus and flood
into the lungs. The lung tissue becomes inflamed. During normal immune function, the inflammatory
process is highly regulated and is confined to infected areas. However, sometimes the immune system overreacts,
and this results in damage to healthy tissue. More cells die and slough off into the lungs,
further clogging them and worsening the pneumonia. As damage to the lungs increases, stage three
begins, potentially resulting in respiratory failure. Patients that reach this stage of infection
can incur permanent lung damage or even die. We see the same lesions in the lungs of those
infected by the novel coronavirus as those with SARS. SARS creates holes in the lungs, so they look
honeycomb-like. This is probably due to the aforementioned
over-reactive immune response, which affects tissue both infected and healthy and creates
scars that stiffen the lungs. As such, some patients may require ventilators
to aid breathing. The inflammation also results in more permeable
alveoli. This is the location of the thin interface
of gas exchange, where your lungs replace carbon dioxide in your blood with fresh oxygen
you just inhaled. Increased permeability causes fluid to leak
into the lungs. This decreases the lungs’ ability to oxygenate
blood, and in severe cases, floods them so that you become unable to breathe. Sometimes, this can be fatal. The immune system’s over-reaction can also
cause another kind of damage. Proteins called cytokines are the immune system’s
alarm system, recruiting immune cells to the infection site. Over-production of cytokines can result in
a cytokine storm, where there is large-scale inflammation in the body. Blood vessels become more permeable and fluid
seeps out. This makes it difficult for blood and oxygen
to reach the rest of the body and can result in multi-organ failure. This has happened in the most severe cases
of CoVid-19. Although there are no specific treatments
for coronaviruses, symptoms can be treated through supportive care. Also, vaccines are currently in development. What can you do to protect yourself from CoVid-19? Advisories vary in different countries, but
the basic protocol comes down to regular hand washing, avoiding close contact with anyone
coughing or sneezing, avoiding unnecessary contact with animals, washing hands after
contact with animals, thoroughly cooking meat and eggs prior to consumption, and covering
your mouth and nose while coughing or sneezing. Respiratory viruses are typically transmitted
via droplets in sneezes or coughs of those infected, so preventing their travel stops
the spread of disease.

Your presentation is very understandable, however, it does not address or even refer to the published study which reduced virus load to zero in 6 days with the combination of hydroxychloroquine and antibiotic azithromycin.
Apparently it accomplishes this by stopping the "over-reactive immune response". I doesn't kill virus, it stops the body from killing itself.
Why not inform and push for this? .

get it over with, get sick, get isolated, get immune, get back to life.

would it be better if those who are healthy deliberately get it and then isolate themselves until healthy again, no longer sick or contagious so then they are immune. then they can go back to normal life.

what if we all shut down until we think its safe then we all go back out into the world only to get it anyways then have to shut down all over again. maybe how many times that cycle will continue to happen?

maybe our doctors, all doctors and politicians should study how taiwan and singapore handled the situation and copy it, if its not to late to do so already.

A friend on a forum sent me this and I believe it. Bat soup my ass. "The virus, it is a bio weapon. And chances are very high that the US released it in China, Iran and Italy. Wuhan area had a war games in early November and sources say that this is the time it got released. The S protein is not natural and the it has an attachment rate of over 1000 times that of a naturally occuring virus. It's not selective and the dispersion rate is way too fast and wide to be a regular virus. China knew this and that is why there was a total lockdown of 85 cities 2 weeks into Feb".
