At the beginning of the winter of 2019, China announced to the whole world that an outbreak of a previously unknown viral disease, which was first called 2019-nCoV, that is, the “new coronavirus of 2019, was recorded in the country. Later, on February 11, 2020, WHO named it COVID-19.

According to the official version, the primary source was the city of Wuhan, where the disease began to spread among visitors and workers in the seafood market. There, including, they sold snakes and bats, which local residents consider delicacies. Perhaps the disease was transmitted to humans from infected animals.

What is coronavirus

This is the name of the family of viruses that infect mammals: humans and some animals - dogs, cats, bats and cattle. To date, scientists have identified 40 species of coronaviruses. So, this family includes the SARS virus, as well as MERS-Cov, which caused an epidemic of the Middle East respiratory syndrome. The name of this group of viruses was given because of a distinctive feature - their shell is studded with spine-shaped processes that give similarities to the corona.

How it can be transmitted

Coronavirus infections can be transmitted both from an infected person and from an animal. It should be remembered: some diseases can be contagious even during the incubation period!

Transmission ways:

  • airborne;
  • airborne dust;
  • fecal-oral;
  • pin.

From such diseases, long-term immunity is not produced, which means that, having recovered, a person can become infected with a coronavirus infection again. The probability of getting sick grows in the winter-spring period.

How the disease caused by coronavirus proceeds

Light form. In this case, the virus causes a respiratory infection, less often its intestinal variety is noted - as a rule, this happens in children. In most cases, the virus leads to the usual SARS, which proceeds without severe symptoms, lasts about a week and ends with recovery.

Severe form. With this development, infection leads to severe acute respiratory syndrome (SARS) or to SARS. Then respiratory failure gradually develops, which in 38% of cases leads to death.

Symptoms of COVID-19

When infected with COVID-19, the incubation period can last longer than 14 days. This can happen if a person has been infected from an animal.

Symptoms with COVID-19 resemble the symptoms of SARS or pneumonia:

  • malaise;

  • muscle and headache;

  • Fever, chills;

  • Temperature over 38 ° C;

  • Pain and heaviness in the chest;

  • shortness of breath;

  • Dry cough;

  • loss of consciousness. This symptom is manifested against the background of destruction of lung tissue.

Seven simple preventive measures

  • Do not touch your eyes, mouth and nose.

  • Avoid close contact and being in the same room with infected people and those who have obvious signs of SARS (runny nose, cough). When communicating with loved ones and colleagues, keep a distance of at least 1 m.

  • Avoid visiting public places and restrict travel by public transport.

  • Wash hands frequently with soap, especially after returning from the street - at least 20 seconds.
