The main symptoms of covid-19 disease caused by Chinese coronavirus

Manifestations of the respiratory syndrome when infected with the 2019-ncoV virus can range from a complete absence of symptoms (asymptomatic) to severe pneumonia with respiratory failure, which can lead to death.

In this case, pneumonia may not always develop. In some cases, gastrointestinal symptoms may occur, including diarrhea. Severe manifestations of the disease may include respiratory arrest, which will require the patient to be connected to an artificial respiration apparatus and assisted in the intensive care unit. Against the background of the severe course of the disease, it is possible to attach a secondary infection - fungal or bacterial.

Unlike a common cold or bronchitis, coronavirus will have a dry cough, not a wet one.

The second important point - at the beginning of the disease, an elevated temperature may not always be. And even if it rises, it will still be lower than with the flu. For example, 39 degrees Celsius is very rare. An increase in temperature and its values ​​indicate the severity of the course of the disease.

Among those who have already identified coronavirus, there are a lot of mild cases. With them, there is no pneumonia at all or it is very weakly expressed. Then a coronavirus infection can occur like a simple cold, it is impossible to distinguish them.

With a more severe course of the disease, patients may experience shortness of breath, shortness of breath. These will be the main distinguishing features of the coronavirus.

Symptoms of 2019-nCoV infection are very similar to the symptoms of other respiratory viral infections: sore throat or sore throat, cough, runny nose, headache, temperature from 37,8 ° C, weakness, general feeling of malaise.

In more severe cases, when the infection goes down from the upper respiratory tract (as happens with SARS), the symptoms intensify. Appears: temperature from 39 ° C, severe cough, shortness of breath, breathing problems, tightness and chest pain.

If these symptoms occur, seek medical attention immediately. You do not have to be diagnosed with coronavirus. Perhaps this is SARS, to which a bacterial infection or pneumonia has joined. But in any case, these are complications that require mandatory medical supervision.

The decisive role in identifying the disease is played by the data of the epidemiological history, i.e. information about the place, circumstances, conditions where the infection occurred. If you have fever, sneezing, coughing and / or shortness of breath, you should immediately seek medical help if you have been in China for the past 14 days or have been in contact with a patient who has arrived from there.

The virus is especially dangerous for people with a weakened immune system and the elderly, as well as patients with concomitant diseases, for example, diabetes mellitus, chronic lung diseases, etc.
