All viruses are dangerous but some can be prevented.
Every few years on the planet there is , which is spoken by many. “Bird flu”, “swine flu”, Ebola, and many others. There are cases when serious epidemics pass and no harm to humans was not applied, and we just received a new kind of virus and begin to look for a way to save human lives from him. Fortunately, as a rule, so. But it appeared not so long ago in China, 2019 coronavirus-nCoV could be something more dangerous. Information on this virus a lot, but it is all superficial. Let's try to understand it more and know whether to fear him.
First of all, let's understand that all this coronavirus — the word that is so often found not only in conversations about the epidemic, but just in medical articles.
In fact, everything is simple and viruses with the same name just United under one name, which is obtained due to the visual similarity of the virus with the crown. This similarity is achieved due to the spinous processes that extend from the shell in different directions.
Coronaviruses (lat. Coronaviridae) family, including June 2019 37 types of viruses incorporated into 2 subfamilies, which affects man, cats, birds, dogs, cattle and pigs.
So, as you can see, the virus infects not only humans, but animals with whom he often comes in contact in everyday life and in their . including can become carriers of the virus, like H5N1. Especially dangerous in this situation are birds because of their ability to transmit the virus over long distances.
looks like coronavirus.
For the First time coronavirus has been detected in 1965 in a patient with acute rhinitis. After that, their number is only growing. The type of human exposure to all coronaviruses manifest themselves in different ways. In addition, they can with different speeds to Express themselves in the form of symptoms and different ways to evade the immune system, they can affect different organs of the human body.
A strike could enter the respiratory system, gastrointestinal tract and nervous system. Possible complications to other organs and systems. Primary reproduction occurs in the respiratory system, particularly in the nasopharynx and upper respiratory tract. In adults this leads to a runny nose, and in children because of the imperfection of the immune system bronchitis and pneumonia.
to be informed about the latest news in dealing with viruses and epidemics, follow
there is, therefore, as a treatment used drugs that are struggling with some of its manifestations, increasing the overall resistance of the organism that help it to better confront the danger.
With the basic concepts of coronaviruses understood. You can now go directly to the most up-to-date, representative — the virus, dubbed 2019-nCoV.
2019 Virus-nCoV, provoking pneumonia, shortness of breath and invasive lung disease, was first recorded in China December 31, 2019.
Fixed the virus in the city of Wuhan (Hubei province). By Chinese standards, the city can hardly be called very densely populated, however, it is home to 12 million people.
this is the Wuhan.
Only 4 days after the detection was recorded for 44 cases of infection with this virus. At the same time, a quarter of cases was in critical condition. Chinese doctors reported the world health organization.
The Investigation, conducted without delay, showed that the likely source of the virus was the city market which sells a lot of seafood and other . To reduce the risk of further spread of the virus, the market is quickly closed on quarantine. It happened already the first of January. That is, the next day, after fixing the first case.
The First death of an infected with the virus 2019-nCoV recorded on 9 January. The victim was 61-year-old man, who, by the way, was a regular customer of this market.
Despite the fact that now the Chinese hospitals, there are about 180 patients at the age from 25 to 89 years, 45 of them in serious or critical condition, 25 people were able to cure. At the same time, the geographical spread of the virus covers not only Wuhan but also the other major cities such as Beijing, Shenzhen, Shanghai and other. There are even cases of the virus spread to Japan, South Korea and Thailand. All cases in these countries visited Wuhan.
China and many other Asian countries are known for their exotic products. For example, there is not just eat, but considered a real delicacy snakes, insects, and various marine life that the Europeans have no culinary interest.
Similar products sold in the market of Wuhan city. But in addition, according to the latest data, there were sold and some animals, the legality of trade which raises some questions.
it looks like the market in Wuhan. Including there was illegal animals.
It is possible that the original source of infection was one of these animals. Such cases in history already happened, so what is the optionshould not be excluded.
As expected, soon after the detection of cases of the disease began to appear recommendations on how to protect yourself against it. Of course, the most logical appears to be the current option to withdraw from Wuhan city. But one of the more serious boards of the world health organization gives the following.
The First thing you should pay attention to all people . Even if you met him away from the place where were recorded outbreaks of disease, do not relax. Better safe than sorry.
As the virus can be contained in a product, you should pay attention to their processing needs. Everything that is not in original packaging should be well washed, and the meat, poultry, fish or eggs are subjected to heat treatment. Avoid raw or undercooked meat.
Of Course, do not neglect washing your hands. If the opportunity to wash my hands not, you should handle them wet with alcohol wipes or a special gel.
Another important point, which is likely not protect you, and will reduce the risk of spreading the virus, is the correct sneezing and coughing. Sneezing and coughing is only in a handkerchief or the elbow bent. Even without the need of preventing this particular virus, it should not sneeze in his hand and in the elbow. Sneezing in your hand, usually right, then we all cling to shake hands and thus further spreads the infection than if you'd just sneezed in space.

Another preventative measure is gauze bandage or a surgical mask when visiting public places. A hundred percent is not able to protect from disease, but some effect there. Moreover, that such method will prevent the virus from spreading its carriers, even if they don't know it yet.
Do Not want to scare highly suspicious readers, but the symptoms of infection with the virus 2019-nCoV is very similar to the common cold or flu. The difference appears a little later.
It all Starts with raising the temperature. So the body fights foreign bodies trapped inside. In addition, among the first manifestations may be noted the fatigue and cough with a little sputum.
About 90 percent of the cases in the first stage have experienced exactly these symptoms. In addition, another 20 percent noted the tightness in his chest. 20 percent of patients had shortness of breath. 15 percent of the feeling of lack of air (dyspnea). Of course, these symptoms could occur together one by one. But all, without exception, patients on the results of the radiographs .
The Main danger of the virus is the probability of a lethal outcome. While the number of such cases is about 1.5 per cent of applicants for assistance.
Perhaps for this reason, the world health organization calls while there should be no restrictions on trade and the flow of tourists to China. In particular, in the city of Wuhan.
Luckily, the virus is far from the most destructive epidemics. For example, the famous Spanish flu or “Spanish flu” in 1918-1919 claimed the lives of about 100 million people (about 5 percent of the world's population at the time). Thus, mortality was about 20 per cent of the total number of cases.
From Ebola died about 1250 people. This is about half of all cases of fever. In that time, from the famous “bird flu” suffered mostly only animals, as the number of human deaths was relatively small at this scale. Against this background, several deaths from a new virus seem to be something which it is not necessary to panic, but we don't know what it may lead in the future, as after fixing a virus less than a month.
urban Ranke Wuhan held a special event.
As mentioned above, the most effective way of dealing with some virus not. This is especially true for new viruses. This is one of the dangers of “news”. For the care of patients applies only symptomatic treatment, but the fruit it bears. So managed to save more than two dozen people (about 10 percent of cases).
The Problem is that 25 January will be Chinese new year. At this time, the people of China . It somewhat 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.
Over the years the development of means to combat viruses, international agencies including the world health organization, have developed a protection mechanism and regional localization of infections.
To the infection is not spread from a quarantine in those areas where presumably could start your journey virus. And so it happened with the urban market, which visited all the sick. After this, restrictions are imposed on the railway stations and airports.
Given the speed of our modern life is only 10-12 hours that the virus was not just in another place, and on the other side of the planet. So, in a few hours it can cover all the continents. It therefore introduced measures against aircraft and trains arriving fromthreat in the region. He watched the thermal imaging and random temperature testing 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 temperature measurements made by all the passengers, then those with identified abnormalities, are sent for additional examination.
Similar systems can scan people in the stream and in case of exceeding the body temperature to inform the operator.
This is because the incubation period in some people can be more normal or just a passenger are bringing products from the region, where raging epidemic. By the way, that is why even a quiet time in the custom in almost all countries is very negative about the transportation of food, especially perishable (cheese, fruit, animal products). Such measures only reduce the risk of proliferation in our high-speed world.
now Let's discuss what you think about the new virus
But do not forget that sometimes the panic becomes unnecessary. I'm talking about those cases when they are hungry for sensations journalists inflate a problem just to the universal scale, sometimes forgetting common sense. This, too, was the result of the acceleration of our world. Not only do we quickly move in space. Even faster “moves” information. She is able to sow panic.
In the case of the 2019 virus-nCoV while nothing extraordinary happened. The number of cases is large, and a new strain of the virus open every day, but to beat anxiety yet. Moreover, the responsible person, apparently, work very well and not allow the virus to be widely disseminated. The main thing to take into account all the precautions and refrain from visiting the troubled region. If all goes well, a serious epidemic will not.
