Coronaviruses are a family of viruses that was discovered in the 1960s
but whose origin is still unknown. Its different types cause different illnesses,
from a cold to a severe respiratory syndrome (a severe form of pneumonia).
but whose origin is still unknown. Its different types cause different illnesses,
from a cold to a severe respiratory syndrome (a severe form of pneumonia).
Most coronaviruses are not dangerous and can be treated effectively. In fact,
most people get a coronavirus at some point in their lives, usually during childhood.
Although they are more frequent in autumn or winter, they can be purchased at any
time of the year.

The coronavirus owes its name to the appearance it presents, since it is very similar
to a crown or halo. It is a type of virus present in both humans and animals.
Three major epidemic outbreaks caused by coronaviruses have been described
in recent years:

Three major epidemic outbreaks caused by coronaviruses have been described
in recent years:
SARS-CoV: Acute and severe respiratory syndrome
(SARS, also known as SARS and SARS) began in China in November 2002,
affecting more than 8,000 people in 37 countries and causing more than 700 deaths.
SARS-Cov mortality has been estimated at approximately 10%.

MERS-CoV: The coronavirus causing Middle East respiratory syndrome (MERS)
was first detected in 2012 in Saudi Arabia. As of October 2019, more than 2,400
cases of infection have been reported in different countries, with more than 800 deaths.
The case fatality is therefore 35%.

COVID-19: In late December 2019, the first cases of a new coronavirus were reported
in the city of Wuhan (China). Since then the drip of new infected by the SARS-CoV-2 virus
(initially called 2019nCoV), which causes COVID-19, has been continuous and its
transmission from person to person has accelerated. Wuhan's reported cases of
pneumonia already far exceed those of the SARS epidemic, but the case fatality
rate is lower.

The World Health Organization (WHO) has declared the pandemic situation.
People are infected in most countries, and health professionals insist on the need to
follow preventive measures and avoid social alarm.

In Spain and other countries the state of alarm has been decreed and the health
authorities insist on the need to stay home to contain the transmission.

Causes
Until now, coronaviruses have been limited to humans.
The origin of these viruses is unknown, but certain animals, such as bats,
are known to act as reservoirs.

As in other viruses that cause pneumonia, when they are transmitted in humans,
the infection usually occurs through the respiratory route, through the respiratory
droplets that people produce when they cough, sneeze, or speak.

Everything seems to indicate that the new corona virus,
COVID-19, also known as Wuhan coronavirus, has an animal origin. In fact,
the first cases have been related to a live animal market in the city of Wuhan, in China.

As for MERS, camels are likely to be an important reservoir for this type of coronavirus
and an animal source of infection in humans, as specified by the World Health
Organization in its descriptive note on the disease. However, the specific role of camels
in virus transmission and the exact route (s) of transmission are unknown.

Originally, the MERS-CoV coronavirus is a zoonotic virus that is transmitted from
animals to people. From the analysis of several of its genomes, the virus is believed to
have originated from bats and was transmitted to camels at some point in the distant past.

The SARS coronavirus is believed to have originated from bats,
subsequently leaping to some other small mammal species, such as the civet,
and lastly to humans.
