What is the coronavirus?

Coronaviruses constitute a large family of viruses with proven disease-causing properties in relation to humans or animals. It is known that a number of coronaviruses are able to cause respiratory infections ranging from the common cold to more serious conditions such as middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). The last of the newly discovered coronavirus causes disease COVID‑19.

What is the COVID-19?

COVID‑19 – an infectious disease caused by the last of the newly discovered coronaviruses. Before the outbreak of the infection in Wuhan, China, in December 2019 on the new virus and the disease were not known.

What are the symptoms COVID‑19?

The most common symptoms COVID‑19 include fever, fatigue, and dry cough. In some patients may experience various aches, nasal congestion, rhinitis, pharyngitis or diarrhea. Usually these symptoms develop gradually and are mild in nature. Some infected individuals have no symptoms or you feel unwell.

Most people (about 80%) the disease ends in recovery, while the specific therapeutic measures are not required. Approximately one out of six cases COVID-19 has severe symptoms with the development of respiratory failure. In the elderly, and persons with existing somatic diseases such as hypertension, heart disease or diabetes, the probability of severe disease is higher. In the presence of fever, cough and difficulty breathing should seek medical help.

The spread of the virus?

Infected 2019‑nCoV can from other people, if they are infected with the virus. The disease can be transmitted from person to person through small droplets emitted from the nose or mouth of the patient COVID‑19 when you cough or sneeze. These drops fall on the surrounding human subjects and the surface. Other people can catch the disease by touching the first such objects or surfaces, and then to the eyes, nose or mouth. In addition, infection can occur by inhalation of fine droplets that are released when you cough or sneeze of a person with COVID‑19. For this reason, it is important to keep the sick person at a distance of 1 meter.

Who monitors the progress of studies on the transmission COVID-19 and will publish information as it is updated.

Is there any virus that causes COVID-19 through the air?

According to current scientific data more important transfer than air, are small droplets emitted from the respiratory tract.

Can you get COVID-19 from a person who shows no symptoms?

The virus is mainly spread through droplets emitted from the respiratory tract during coughing or sneezing. The risk of infection from a person with no symptoms is very low. On the other hand, many people have symptoms COVID-19 are expressed very weakly. This is especially true for the early stages of the disease.

Thus, the risk of transmission COVID-19 from a person who does not feel ill and only has a weak cough, there is. Who monitors the ongoing research on the question of the time interval during which a sick person is contagious, and will publish information as it is updated.

Can I get COVID-19 through the feces of the sick person?

Apparently, the risk of exposure to 2019-nCoV through the feces of an infected person is small. According to preliminary studies, the virus in some cases can be detected in the faeces, however, such transmission mechanism does not play a leading role in the current outbreak of the disease. Who is studying the results of the ongoing studies regarding the transmission of COVID-19 and will publish information as it is updated. This risk cannot be completely dismissed and this once again confirms the importance of regular hand washing after using the toilet and before eating.

Measures personal protection for all

Follow the latest information on the outbreak, which can be found on the website of the who, as well as to the national and local representatives of public health services.

Governments and health authorities are taking energetic response to every new case of infection COVID‑19. In the presence of imposed at the local level, travel restrictions, movement or mass events to observe this mode. Supporting measures to control the spread of the disease, you can reduce the risk of infection or spread COVID‑19.

At the same time conducted clinical trials of several tools of both Western and traditional folk medicine. Who will continue to publish updated information as the emergence of clinical data.

This is the same virus which causes SARS (SARS)?

No. The virus that causes COVID‑19, belongs to the same family of viruses as the causative agent of severe acute respiratory syndrome (SARS‑Cov), but that’s another virus.

How long is the incubation period COVID‑19?

The incubation period is the time period between exposure and appearance of clinical symptoms of the disease. According to most estimates, the incubation period COVID‑19 ranges from 1 to 14 days and usually is about five days. These estimates will be refined as new information becomes available.

Can a person be infected COVID-19 from the animal?

Coronaviruses constitute a large family of viruses and are widely distributed in animals. The people have been infected with these viruses and subsequent transmission to others occurs from time to time. For example, an established fact of human infection with SARS‑Cov from civet, and MERS‑Cov from dromedaries. Possible source 2019‑nCoV among animals is not yet known.

According to research (including pre-about the pathogen COVID-19), the virus can remain viable on surfaces from a few hours to several days. Specific dates depend on a number of conditions (e.g., surface type, temperature and environment humidity).

If you suspect that a surface may contain a virus, to kill microorganisms and protect yourself and others treat it the conventional disinfectant. Do not forget to handle hands with alcohol or wash them with soap and water. Avoid touching your eyes, mouth or nose.
