Everything you need to know about coronavirus

Everything you need to know about coronavirus - rictasblog.com

The outbreak of a new coronavirus is leaving dozens of victims in China and threatens to spread.  It is known as 2019-nCoV, or more commonly as Wuhan coronavirus, named for the city of Wuhan, China, the epicenter of the virus.This is what you should know.

What is the new coronavirus?

Coronaviruses are actually a family of viruses that mostly affect animals, although they can pass to humans, causing respiratory infections similar to influenza influenza viruses, although they are different. This coronavirus is a mutation so new that it still has no name. WHO has assigned the code 2019-nCoV.

Are there other coronaviruses?

One of the best known is the virus that caused SARS (severe acute respiratory syndrome) in 2003, which infected 8,000 people, 10% of whom died. In 2012 the MERS (Middle East Respiratory Syndrome) was identified, but this mutation did not pass easily from person to person and there were few victims. However, in 2015 the MERS caused more than 850 deaths in Korea.

Where does the infection come from?

The outbreak of the new coronavirus originated in December 2019 in Wuhan city in central China, in a food market. In less than a month the virus infected more than 2,000 people causing more than 100 deaths.

How is it transmitted?

The mechanisms of contagion of the new coronavirus are still unclear. It is not yet known which animal transmits it originally, but it is speculated that it may be snakes or bats. Yes it has been confirmed that it is later transmitted from person to person.

What symptoms does it cause?

The new coronavirus initially causes shortness of breath, fatigue, runny nose, cough, headache, fever and discomfort. Symptoms appear a week after infection and are similar to those of the flu, so many people do not go to the hospital.

It is mortal?

In people whose defenses are weakened, such as the elderly, the sick and children, the new coronavirus can cause pneumonia, severe acute respiratory syndrome, kidney failure and in some cases death. The number of victims as of this date is 595 out of a total of almost 28,390 affected.

It's contagious?

The potential for contagion is measured with a variable called Ro, the number of people who are infected by each new case. Estimates for the new coronavirus are between 1.3 and 3.8, but this does not indicate its danger. Measles has a Ro between 12 and 18, while the SARS, with hundreds of victims, had 3.

Which is the treatment?

Antibiotics do not work against any type of virus, neither the flu nor the coronavirus. Because it is a new virus, there is no vaccine and, as with the flu, only symptoms can be treated.

Where is it spreading?

The Chinese government maintains strict censorship of the information about the outbreak, so it is not possible to know for sure the extent of the infection. It is known that it is not limited to Wuhan Province and that half of the new cases appear in other provinces. To date there are only confirmed cases in the United States, Canada, Vietnam, Germany, South Korea, Japan and Taiwan, especially of people who traveled to China.

How to control the infection?

In the absence of a vaccine, the only way to prevent the coronavirus infection from spreading is quarantine.

Can you mutate?

Viruses are so simple that they lack enzymes that prevent mutations in higher organisms such as animals or plants. One of the fears is that the virus undergoes a mutation and become more contagious or virulent, becoming a "supervirus", but this has not happened yet.
