What's missing from all that information (all from official sources) is the awful truth. And it's true for Covid-19 as well.The original SARS
A contagious and sometimes fatal respiratory illness caused by a coronavirus.
SARS appeared in 2002 in China. It spread worldwide within a few months.
How it spreads
SARS is a virus transmitted through droplets that enter the air when someone with the disease coughs, sneezes, or talks.
Fever, dry cough, headache, muscle aches, and difficulty breathing are symptoms.
No treatment exists except supportive care.
Polio
Poliovirus is very contagious and spreads through person-to-person contact. It spreads through contact with the stool (poop) of an infected person or droplets from a sneeze or cough. If you get stool or droplets from an infected person on your hands and you touch your mouth, you can get infected.
Whole body: fatigue, feeling faint, fever, or wasting away
Muscular: muscle weakness, loss of muscle, or muscle quiver
Also common: headache, nausea, or slow growth
Influenza
A common viral infection that can be deadly, especially in high-risk groups.
The flu attacks the lungs, nose, and throat. Young children, older adults, pregnant women, and people with chronic disease or weak immune systems are at high risk.
Symptoms include fever, chills, muscle aches, cough, congestion, runny nose, headaches, and fatigue.
Very common
HOW IT SPREADS
By airborne respiratory droplets (coughs or sneezes).
By touching a contaminated surface.
By saliva (kissing or shared drinks).
By skin-to-skin contact (handshakes or hugs).
Smallpox
In addition to flu-like symptoms, patients also experience a rash that appear first on the face, hands and forearms, and then later appears on the trunk.
There's no treatment or cure for smallpox.
HOW IT SPREADS
By airborne respiratory droplets (coughs or sneezes).
By saliva (kissing or shared drinks).
By skin-to-skin contact (handshakes or hugs).
By blood products (unclean needles or unscreened blood).
Cholera
A bacterial disease causing severe diarrhea and dehydration, usually spread in water.
Cholera is fatal if not treated right away.
Key symptoms are diarrhea and dehydration. Rarely, shock and seizures may occur in severe cases.
Cholera is caused by a number of types of Vibrio cholerae, with some types producing more severe disease than others.
It is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria
https://www.science.org/content/article ... er-tell-usAlthough wastewater monitoring has been used to track polio and other pathogens for decades, the COVID-19 pandemic has led to an explosion of interest. The technique takes advantage of the fact that SARS-CoV-2 replicates in the digestive system and is shed in high quantities, often before symptoms appear. (The virus is also detected in urine, though not as consistently.) That provides an inexpensive way to monitor infections in thousands or even millions of people without pesky nose or throat swabs, or to predict where cases might be about to surge and hospitals risk getting overburdened. The genetic sequences of the shed virus can also provide hints about how it is evolving.

A technique that detects coronavirus strains circulating in a community could become an early-warning system
What's the obvious but missing factor in all this?
It was stated in the SARS research, and I found it while researching the origin of the flu, and it even came up when they reported wild deer had Covid 19
But still, it's seems to be a goddamn mystery to the published science, and the advice on how to avoid getting sick, (from disease that can kill you).
I find that strange, and incredibly shitty.
