What you need to know about the Chinese coronavirus 2019-nCoV?

Every few years, the planet appearsa serious disease that many are talking about. Bird Flu, Swine Flu, Ebola and many more. There are cases when serious epidemics pass by and do no harm to a person, and we just get a new type of virus and start looking for a way to save human lives from it. Fortunately, this is usually the case. But the 2019-nCoV coronavirus, which appeared not so long ago in China, may become something more dangerous. There is a lot of information on this virus, but all of it is superficial. Let's try to understand it in more detail and understand whether it is worth it to be afraid.

All viruses are dangerous, but some can be protected.

First of all, let's look at what coronavirus is in general - a word that so often occurs not only in conversations about epidemics, but simply in medical articles.

What is coronavirus?

In fact, everything is simple and viruses with suchthe name is simply combined under one name, which is obtained due to the visual similarity of the virus with the crown. This similarity is achieved due to the spiky processes that extend from the membrane in different directions.

Coronaviruses (lat. Coronaviridae) is a family that includes in June 2019 37 types of viruses combined in 2 subfamilies that infect humans, cats, birds, dogs, cattle and pigs.

That is, as we see, the virus affects not onlyman, but also animals with which he most often contacts in everyday life and in his economic activity. Animals including can become carriers of the virus, as was the case with H5N1. Particularly dangerous in this situation are birds because of their ability to carry the virus over long distances.

This is what the coronavirus looks like.

Coronavirus was first detected in 1965 inpatient with acute rhinitis. After that, their number only grew. By the type of human exposure, all coronaviruses manifest themselves in different ways. In addition to the fact that they can manifest themselves at different speeds in the form of symptoms and bypass the immune system in different ways, they can affect different organs of the human body.

The respiratory system may be affected.gastrointestinal tract and nervous system. Complications to other organs and systems are also possible. Primary reproduction occurs in the respiratory system, in particular in the nasopharynx and upper respiratory tract. In adults, this leads to a runny nose, and in children, due to imperfections in the immune system, to bronchitis and pneumonia.

There are no effective remedies for many viruses,therefore, as a treatment, drugs are used that fight its individual manifestations, increasing the body's overall resistance, helping it more effectively resist danger.

With the basic concepts of coronaviruses sorted out. Now you can go directly to its most relevant representative today - the virus, called 2019-nCoV.

How did the 2019-nCoV virus appear?

The 2019-nCoV virus, which causes pneumonia, shortness of breath, and invasive lung damage, was first reported in China on December 31, 2019.

This virus was detected in Wuhan (Hubei Province). By Chinese standards, the city can hardly be called very densely populated, however, 12 million people live in it.

This is what Wuhan looks like.

Only 4 days after the discovery was44 cases of infection with this virus have already been recorded. At the same time, a quarter of patients were in critical condition. Chinese doctors reported this to the World Health Organization.

Hot pursuit investigationshowed that, most likely, the source of the virus was the urban market, which sells a lot of seafood and other animal products. To reduce the risk of further spread of the virus, the market was hastily quarantined. This happened on the first of January. That is, the next day, after fixing the first case of the disease.

The first death of a 2019-nCoV virus infected was recorded on January 9th. The victim was a 61-year-old man, who, by the way, turned out to be a regular buyer of this market.

Despite the fact that now in hospitals in Chinathere are about 180 patients aged 25 to 89 years, 45 of whom are in serious or critical condition, 25 people were able to cure. At the same time, the geography of the spread of the virus covers not only Wuhan, but also other large cities, such as Beijing, Shenzhen, Shanghai and others. There are even cases of the spread of the virus to Japan, South Korea and Thailand. All patients in these countries visited Wuhan.

The mysterious virus from China is now in Japan and Thailand. Experts do not understand how it is distributed

Illegal animals on the market in China

China and many other Asian countries are famousits exotic products. For example, they do not just eat there, but also consider it a real delicacy of snakes, insects and various marine inhabitants, which Europeans do not cause any culinary interest.

Similar products were sold in the market of Wuhan. But besides this, judging by the latest data, some animals were also sold there, the legality of trade in which raises some questions.

This is how the market of Wuhan looks like. Including there were illegal animals.

It is possible that initially one of these animals served as the source of infection. Such cases have already happened in history, so this option should not be ruled out.

How to protect yourself from the 2019-nCoV virus?

As expected, in the very near future aftercase detection began to appear recommendations on how to protect yourself from it. Of course, the most logical option now seems to refuse to visit the city of Wuhan. But of the more serious advice, the World Health Organization gives the following.

The first thing you should pay attention to everyonepeople with signs of a cold or flu. Even if you have met him far from the place where the outbreaks were recorded, you should not relax. Better safe than sorry.

Since the virus can be found in foods,pay attention to their proper handling. Everything that is not in the original packaging should be washed well, and heat the meat, poultry, fish or eggs. Avoid raw or poorly fried meat.

Naturally, do not neglect hand washing. If there is no opportunity to wash your hands, it is worth treating them with wet alcohol wipes or a special gel.

Another important point, which is probably notprotects you, and will reduce the risk of spreading the virus, is proper sneezing and coughing. Sneezing and coughing is only in a handkerchief or in a bent elbow. Even without the need to prevent this particular virus, it is worth sneezing not in the palm of your hand, but in your elbow. Sneezing in the palm of the hand, as a rule, the right one, we then grab hold of everything, shake hands with each other and thereby spread the infection even more than if we simply sneezed into space.

A clear demonstration of how to properly sneeze.

Another prophylactic isgauze bandage or medical mask when visiting public places. One hundred percent it is not able to protect against the disease, but there is a certain effect from this. Moreover, this method will prevent the spread of the virus by its carriers, even if they do not yet know about it.

Symptoms of the Chinese virus 2019-nCoV

I don’t want to frighten strongly suspicious readers, but the symptoms of infection with the 2019-nCoV virus are very similar to ordinary colds or flu. The difference appears a bit later.

It all starts with a rise in temperature. So the body fights with foreign bodies that have got inside. In addition, among the first manifestations, fatigue and cough with a small amount of sputum can be noted.

About 90 percent of cases in the first stageexperienced these very symptoms. In addition, another 20 percent noted chest tightness. 20 percent of patients had shortness of breath. 15 percent feeling of lack of air (dyspnea). Naturally, these symptoms could occur both together or one at a time. But in all patients without exception, pneumonia was diagnosed according to the results of the radiograph.

What is the danger of 2019-nCoV virus?

The main danger of the virus lies in the likelihood of death. So far, the number of such cases is about 1.5 percent of those who applied for help.

Perhaps for precisely this reason, the World Health Organization is calling for so far not to impose any restrictions on trade and tourist flows to China. Including, in the same city of Wuhan.

Fortunately, the current virus is still far from the mostdevastating epidemics. For example, the famous Spanish flu or “Spanish flu” in 1918-1919. killed about 100 million people (about 5 percent of the world's population at that time). At the same time, mortality amounted to about 20 percent of the total number of cases.

About 1250 people died from Ebola. This is about half of all people with fever. At that time, only the animals suffered from the famous “bird flu”, since the number of human deaths was relatively small with such a scale. Against the background of all this, several deaths from the new virus seem to be something because of which it is not worth raising a panic, but so far it is not known what it can result in in the future, since a month has not passed since the virus was fixed.

Special events are held at the Wuhan City Market.

As mentioned above, an effective waythere is no fight against some viruses. This is especially true for new viruses. This is one of the dangers of the "news." So far, only symptomatic treatment is used to help patients, but it bears its fruits. So more than two dozen people have been saved (about 10 percent of cases).

The problem is that January 25th will be Chinesenew Year. At this time, the inhabitants of the Middle Kingdom traditionally dispersed around the world. This slightly increases the risk of spreading the virus to other countries. Moreover, the virus is transmitted from person to person, although at first this method of distribution was considered impossible.

Chinese disease or Asian virus. What measures are being taken?

Over the years, the development of virus control tools, international agencies, including the World Health Organization, have developed a mechanism for the protection and regional localization of infections.

Should I worry about a new virus found in China?

So that the infection does not spread, immediatelyquarantine is introduced in those places from which the virus could supposedly start its path. And so it happened with the city market, which was visited by all sick. After this, restrictions are introduced at train stations and airports.

Given the speed of our modern life,just 10-12 hours is enough for the virus to appear not just in another place, but on the other side of the planet. So, in a matter of hours, it can cover all continents. That is why measures are being introduced in respect of aircraft and trains arriving from a dangerous region. He himself observed thermal imagers and selective measurements of the temperature of suspicious passengers when flying between Asian cities in China, Malaysia, Singapore, South Korea, and other countries. If the risk of spread is very high, the checks cease to be selective and the temperature is measured for all passengers, after which those who have deviations from the norm are sent for an additional examination.

Similar systems can scan people in the stream and in case of excess of body temperature inform the operator about it.

All this does not allow to be completely eliminated.the spread of the disease, since the incubation period in some people may be longer than usual or just a passenger will bring food from the region where the epidemic is raging. By the way, that’s why, even in a quiet time, the customs of almost all countries have a very negative attitude to the transport of food products, especially perishable ones (cheese, fruits, animal products). Only such measures can reduce the risk of spread in our high-speed world.

Let's discuss in our Telegram chat what you think about the new virus.

But, do not forget that sometimes panicbecomes redundant. I’m talking about those cases when journalists who are hungry for sensations inflate the problem simply to a universal scale, sometimes forgetting common sense. This, too, was the result of accelerating our world. Not only we quickly move in space. The information “moves” even faster. She is able to sow panic.

In the case of the 2019-nCoV virus, nothing yetextraordinary did not happen. The number of cases is large, and a new strain of the virus does not open every day, but it is too early to sound the alarm. Moreover, the responsible persons, apparently, work very competently and do not allow the virus to become widespread. The main thing is to take into account all precautions and refrain from visiting the problem region. If all goes well, there will be no serious epidemic.
