coronaviruses (coronaviridae) are a family that includes (as of january 28, 2020) 40 species of viruses, which are grouped into 2 subfamilies (letovirinae and orthocoronavirinae). coronaviruses affect humans, cats, dogs, birds, pigs, cattle and hares. for the first time, the coronavirus was officially recorded in 1965 in a patient with acute rhinitis. of the 40 types of human viruses, only 6 were affected until recently, and after the recent events in china (december 2019-january 2020) – already 7.
what affects the coronavirus (not necessarily all at once):
- Gastro-intestinal tract.
- respiratory system.
- the nervous system.
Coronavirus causes a plentiful runny nose in adults, and bronchitis and pneumonia in children. Varieties of coronaviruses have been the causative agents of outbreaks of new coronavirus pneumonia, Middle East respiratory syndrome and SARS.
The unknown virus, which was seen in early December in the city of Wuhan in China, belongs to coronaviruses and was named 2019-nCoV. This virus (according to Wikipedia) is assigned to the subfamily of orthocoronaviruses (Orthocoronavirinae), further classified as betacoronavirus (Betacoronavirus) and sarbecovirus (Sarbecovirus). The latter subspecies also includes severe acute respiratory syndrome, which was reported in November 2002 in the Chinese province of Guangdong, and became known as “purple death” or “SARS”. Then out of 8098 infected people, 774 people died.
Where do new viruses come from? New viruses are constantly found – they jump from animals to people. For example, it is believed that the above-mentioned SARS was transmitted by Asian civets (according to another version, the source of the disease was bats). The solution to the problem is simplified if you find out which animal transmitted the coronavirus to a person. at the moment, it is not known from whom 2019-ncov was transmitted, but there is an assumption that it came from a chinese cobra, which, in turn, could have picked up the virus from the same bats that it hunts.
What do you need to avoid getting sick (applies to areas where the coronavirus was detected)?
- Do not visit places with a large crowd of people.
- Avoid contact with people who show signs of a cold.
- To wear masks.
- Wash your hands.
- Do not eat undercooked or undercooked meat.
As of March 31, 2020, the situation is extremely sad. Russia has introduced a self-isolation regime to prevent the spread of the 2019-nCoV virus.
Additional information: now the virus is called SARS-CoV-2 (previously-2019-nCoV), and the infectious disease caused by it is COVID-19
The presence of a coronavirus infection in a person is determined by tests for antibodies to the coronavirus.
