Coronavirus Outbreak: All the Secrets Revealed About the Covid-19 Pandemic. A complete Rational Guide of its Evolution, Expansion, Symptoms and First Defense

The Mode of Transmission
The Transmission Mode Much of how Covid-19, a new corona virus, spreads
is unclear. Current awareness is based in large part on what is learned of
related corona viruses. Corona viruses are a large family of viruses
commonly found in many different animal species, including camels, goats,
cats, and bats. Rarely can animal corona viruses infect people, and then
spread among people including MERS, SARS, and now with Covid-19. Most
respiratory viruses are spread by sneezing and coughing. Although the
Chinese authorities initially played down the possibility of human-to-human
transmission, substantial and sustained transmission among people has now
become apparent. Chinese scientists have cautioned that some infected people
may transmit the virus to others even before they develop illness or

experience any symptoms, though a published study documenting
asymptomatic transmission in Germany has been criticized as inaccurate.
If the virus can be spread by individuals with no symptoms at all or mild
symptoms due to respiratory disease— including headache or back ache—
that is terrible. They're up and about, going to work or the gym or religious
services, and breathing on or touching other people when people don't know
they're sick. Most often, the spreading from person to person happens within
close contacts (about 6 feet). It is thought that spreading from person to
person occurs primarily through respiratory droplets created when an infected
person coughs or sneezes, similar to how influenza and other respiratory
pathogens spread. Such droplets may land in nearby people's mouths or
noses, or probably be inhaled into the lungs. Whether a person can get Covid-
19 by touching a surface or object with the virus on it, and then touching their
own mouth, nose, or probably eyes, is currently unclear. Usually, people are
thought to be most infected with most respiratory viruses when they're most
symptomatic (the sickest).
It is important to note that the ease with which a virus spreads will vary from
person to person. Many viruses (such as measles) are highly contagious,
while other viruses are less so. There's much more to learn about the
transmissibility, frequency, and other characteristics associated with Covid-
19 and ongoing investigations. This information will help the risk assessment
further.
