the Vast majority of all cases of coronavirus generally do not transmit the virus to anyone. But 20% is so-called superastronomical. To such conclusions scientists have come to Hong Kong. Another discovery concerns previously identified symptom of the coronavirus that causes loss of smell. It turns out that some patients can’t smell and after recovery.
This unpleasant symptom science called anosmia. That loss of sense of smell — satellite COVID-19 has long been known. Found out recently American doctors, is the fact that for some patients even after recovery, months later, the smell has not returned.
what it’s Like to live without smells that shows this experiment, where people try to guess what they are eating only one flavor, without using other senses.
German molecular biologists have discovered that the coronavirus enters the human brain through the olfactory receptors in the nose, and through them — in the Central nervous system. These data are the Germans got, studied the tissue samples of 32 patients who died of coronavirus.
“the virus penetrates the Central nervous system and it affects the center that smell”, — says Mikhail Kostinov, head of the laboratory of vaccination and immunotherapy of allergic diseases scientific research Institute of vaccines and sera named after I. I. Mechnikov.
In any case, the history of clinical observations is still too short. It is known that through three months to some ill smells never came back. Well, maybe I’ll come back in four or five.
To combat the virus and most importantly to understand how it spreads and turns out to be who distributes.
“Superspreader” — this English term scientists call the special people.
in fact, talking about the fact that 20% of the infection responsible for the vast majority of all cases of transmission — namely, 80%. Such individuals, who infect themselves around the maximum number of people, called the soupirrespectively.
There is another aspect to the opposite. Virologists found that 70% of people infected with coronavirus, never passed it to anyone else, they are the chain of infection was broken.
“It is a human trait, as it effectively multiplies the virus, or it is coincidence. Someone is sick at home, and someone traveling in an airplane, riding the train” — reflects Alexander Lukashev.
Trying to build a chain of infections, epidemiologists turn into detectives. Passed on the heels of a 53-year-old British citizen in his recent past, infectious disease specialists have restored a complete picture.
“a Gentleman picked up the infection at a conference in Singapore. When he returned, went to a ski resort in France, staying there in the chalets. Four or five people were infected there. He then returned to Britain, where probably spread the virus further. This is a very disturbing phenomenon –superastronomical,” — said Angus Dalgleish, Professor of the University of London Saint George.
However, the phenomenon has been open for quite some time.
in 2011 published the study, according to which a minority is guilty in infecting most different diseases such as malaria. Scientists named it the “80-20 rule”. Thus, its superastronomical was in each of the epidemic faced by humanity.
