What is coronavirus?
Coronavirus is an acute viral disease characterized by a predominant lesion of the respiratory system and the gastrointestinal tract. Coronavirus is a zoonotic infection, that is, it can be transmitted to people from animals.
Classification
There are several varieties of coronavirus that causes disease in humans.
Three groups of viruses are distinguished depending on the genetic properties of the pathogen:
- HCoV-226E human viruses;
- HCoV-OC43 human viruses, HECoV intestinal pathogens;
- coronaviruses SARS-CoV and MERS-CoV;
- human rotaviruses HNoV.
- Coronavirus in humans of the first or second group is considered the causative agent of not severe respiratory viral infections.
The most severe clinical manifestations can be observed when infected with the following pathogens:
- SARS-Cov virus causes the development of SARS or severe acute respiratory syndrome;
- MERS-CoV virus causes the Middle East respiratory syndrome, which is characterized by the development of acute p
...neumonia and renal failure;
- 2019-nCov virus causes the development of respiratory distress syndrome.
Symptoms
Especially difficult for children and elderly people to carry the infection, for these age groups, complications that can develop during the disease are very dangerous. Children get sick more severely due to the fact that their immune system has not yet encountered this virus, and for older people, as well as for people with chronic diseases, the virus is dangerous due to a weakened immune system.
Risk groups
- Children
- People over 60
- People with chronic lung diseases (bronchial asthma, chronic obstructive pulmonary disease)
- People with chronic diseases of the cardiovascular system (congenital heart defects, coronary heart disease, heart failure)
- Pregnant women

mucus that are released during sneezing, coughing a conversation. Contact transmission is also possible.
Common symptoms
Depending on the specific type of pathogen, the symptoms can vary significantly, both in severity and in combination options.
- Temperature rise
- Chills, general malaise, weakness, headache, muscle pain
- Decreased appetite, nausea and vomiting are possible
- Conjunctivitis (possibly)
- Diarrhea (possible)
- On average, the disease lasts about 5 days. If the temperature lasts longer, complications may have occurred.
Virus transmission methods
The virus is transmitted by direct contact with a sick person. The transmission mechanism of the virus is airborne.
According to doctors who studied patients with abdominal symptoms and loose stools, diarrhea can be a secondary route of transmission of this virus. The main path, as it is now believed, is airborne, that is, the transmission of the pathogen through the cough of an infected person.
Precautionary measures
WHO has already issued recommendations. And here's what they recommend:
- use alcohol-based products;
- cover your mouth and nose with this or with a rounded elbow;
- Avoid close ties to the flu;
- Thermally process meat and eggs before eating;
- Avoid unprotected contact with wild animals and livestock.
Statistics
Initially it was reported that the Chinese government will spend $ 144 million to fight against coronavirus. Hubei Province has already received these funds. Later it turned out that in China 60.33 billion yuan, equal to 8.74 billion dollars, were allocated to curb the spread of the new strain of coronavirus pneumonia.
Along the way, it became known that the first clinical trials of a vaccine against a new coronavirus can be carried out after 6 weeks.
China also in record time built a hospital with a thousand beds at the epicenter of the epidemic (that
is, in Wuhan). In record - it means 10 days. The network even appeared video of the construction of hospitals.
About 15,000 people become infected per day, 1,000 people recover and 250 people are fatal.

How to recover from coronavirus?
There is no vaccine yet. It is being actively developed, but it requires testing. And all this with mechanical ventilation. It also takes time. However, there is currently no data on the effectiveness of treatment for HIV patients.
