The new Coronavirus - We solve doubts

Coronaviruses are a type of virus family that usually affects animals. On certain occasions there may be transmission with humans. There are many types of coronaviruses, and all of them when they affect a person, he will study with a cold clinic.

The new Coronavirus

At the moment in 2020 the epidemiological alert is activated by a detection of a coronavirus in the Chinese city of Wuhan in December 2019. It was initiated by the detection of 27 cases of pneumonia of unknown causes, beginning the clinical symptomatology as of December 8, 2019 The common link was the exhibition in a market where seafood, fish and live animals from this same city were traded. On January 7, 2020, Chinese scientists identify the type of virus and classify it as "new coronavirus", 2019nCoV. There are currently several countries with people affected by coronaviruses in addition to China such as Thailand, Japan, or South Korea.

For sure, the actual method of transmission of this type of virus and its severity is really unknown. It is estimated that it has a lethality rate close to 3%, specifically 2,9%. In relation to other coronaviruses it is estimated that this type of transmission is due to respiratory droplets of more than 5 microns in size and contact with infected secretions. Regarding the issue of incubation of the disease, it is thought to be around 2 to 12 days although some evidence indicates that it could reach up to 2 weeks.


Since there is still a lot of data to know, it is thought that the initial origin has been an animal focus that has transmitted it to a human being. Many coronaviruses have the ability to spread to humans.


The typical clinic of an infection with the new coronavirus 2019-nCoV, are typical catarrhal symptoms such as cough, sore throat, fever or dyspnea. If the patient has a history such as immunosuppression, or cardiac or pulmonary affectations, it can lead to more serious conditions such as pneumonia, severe respiratory failure, renal failure and in the worst case death.


Regarding the coronavirus transmission mode, in relation to other viruses of the same family it seems that it is with direct contact with animals or infected people through the droplets of saliva that come out when coughing or talking with a size of more than 5 microns , or by contact with these secretions with mucous membranes such as the mouth, nose or eyes.

Although the disease is being transmitted through contact from person to person, at first the data indicates that they do not have a high contagious component, as has been said, close contact with the secretions of the infected person is required and it is This transmission is unlikely to occur through the air over distances greater than one or two meters, since the weight of the drop infected by the new coronavirus 2019-nCoV would not come into direct contact with another person.

Initially as in most viral infections, treatment is symptomatic, this means alleviating the signs and symptoms. The use of antibiotics is not indicated against viral infections since in this way we cause an increase in the pharmacological resistance of some bacteria.

As of February 5, 2020, we did not find any positive case of a new coronavirus 2019-nCoV, but it is true that those from this city can cause cases to be imported. Extreme precautionary measures in those coming from this city and presenting a respiratory infection clinic.

Protection measures

Universal measures of individual protection against respiratory tract infections include frequent hand hygiene either with soap and water or alcohol solution, with special emphasis after direct contact with sick people or their surroundings. If we suspect that there are signs of respiratory involvement such as coughing or sneezing, avoid close contact with the affected person. When coughing or sneezing it is important to cover your mouth and nose with a tissue and then proceed to handwashing.

At the moment in our country no special precautions are necessary beyond the usual ones with food or animals. The Ministry of Health keeps the Alerts network informed with periodic updates that are also accessible to the public (, and a protocol has also been developed of action before the appearance of possible suspicious cases.
