He pointed out that the transmission rate of Omicron has never been seen in the previous mutant virus. At present, 77 countries / regions have reported the detection of the mutant virus. In fact, Omicron virus has appeared in most countries, but it has not been found in some countries.
Tan Desai pointed out that even if the symptoms of infection with the Omicron strain are not too serious, if a large number of cases are caused, the health system will be overwhelmed again.
South African president's new crown test report is positive
South Africa was the first country to report the Omicron strain. The number of newly confirmed cases in the country doubled in just one month, and reached a new high of one-day confirmed cases since the beginning of the epidemic last weekend.
It is reported that South African President ramausa came to an uncomfortable conclusion after visiting four countries in West Africa, and his COVID-19 test results were positive. It is being monitored by the South African military health service under the South African Defence Force and is now undergoing self isolation in Cape Town.
In Gauteng Province, the "epicenter" of the epidemic in South Africa, the number of new infections increased by 400% in the first week of December, of which more than 90% were caused by Omicron strain.
It is worth mentioning that there were 22400 new confirmed infections in South Africa, 19000 new confirmed cases last Friday, compared with about 200 new cases a day a few weeks ago. South African health minister fahra said that in the past month, the number of new infections in South Africa has reached 90000.
However, according to the latest data released by the National Institute of infectious diseases of South Africa, among the patients hospitalized due to Omicron infection in recent weeks, the severe rate is about 30%, which is half lower than the previous waves of local outbreaks. Local doctors also said that according to the observation so far, Omicron is more infectious, but the symptoms of the patients are more mild.
Omicron infection increased significantly in the United States
According to the latest statistics released by Johns Hopkins University, as of the 13th local time, there were more than 50 million newly diagnosed cases and nearly 800000 deaths in the United States. The two data still rank first in the world.
Among them, Omicron virus is emerging. According to the data released by the U.S. CDC on Tuesday, according to the sequencing samples, it is expected that 2.9% of the cases reported in the United States last week were Omicron infection, significantly higher than 0.4% the previous week.
Recently, some media have found the abnormality of the source of Omicron's communication.
It is reported that the United States reported the first case of Omicron variant infection on December 2. The case was a 30-year-old man from Minnesota, and he infected the new crown on November 23, which was not only earlier than November 24, when South Africa first reported Omicron to the who, but also earlier than November 26, which was named by the WHO.
And the "patient zero" of Omicron didn't know how he was infected with Omicron.
Omicron case in Japan
According to the Japan Broadcasting Association (NHK), on the 13th, the Japanese Ministry of health, labor and welfare confirmed that four cases of infection with the new crown Omicron variant were detected among those who entered the country from the 6th to the 9th. Among the four people diagnosed, two have stayed in the United States, one has gone to Nigeria and one has stayed in Kenya.
Three of the four people were vaccinated with two doses of Pfizer vaccine, and they were asymptomatic infected. At present, four people are placed in isolation in medical institutions.
According to NHK statistics, including the latest 4 cases, the number of cases of Omicron virus infection in Japan has increased to 17.
It is reported that Japan's domestic epidemic crisis had a "cliff" decline. On October 31, the number of newly confirmed cases in Japan decreased from more than 20000 in July and August to more than 200.
Recently, influenced by the "COVID-19" strain, Japan has banned the entry of foreigners from all countries and regions, so that the epidemic situation will rebound again.
The first death of Omicron in Britain
Scientists all over the world are paying close attention to their own Omicron strain.
Omicron's spread in Britain is "quite amazing". A group of experts from the London School of hygiene and tropical medicine warned that without further restrictions, Britain will usher in a new round of epidemic peak in January next year.
British Prime Minister Boris Johnson has confirmed that there is at least one case of death from infection with the Omicron strain in Britain.
According to the prediction of the model, under the most pessimistic circumstances, the infection of Omicron virus strain may cause 25000 to 75000 deaths in the country by the end of April next year.
Not only that, two British infectious diseases experts have warned recently that the spread of COVID-19's variant of the Olympic Games in Britain seems to have surpassed that of South Africa. In addition, the novel coronavirus pneumonia alert has been upgraded to four level in COVID-19 because of the rapid increase in the infection rate of the five cases.
The number of infections in other European countries rose
After Belgium reported the first infection case of "Omicron strain" in Europe, Germany and Italy confirmed the infection cases of "Omicron variant strain" one after another, and the Netherlands and the Czech Republic also reported the discovery of relevant suspected cases.
Bavaria, Germany, reported two confirmed cases of "Omicron strain" infection. The patients entered the country from Munich Airport.
As of the week of the 13th, the cumulative number of newly confirmed cases in Denmark in the seven days also broke the record, reaching 46189, a surge of more than 50% over the previous week. Danish health authorities said that the Omicron strain is expected to become the mainstream strain in Copenhagen this week, with 3473 confirmed cases of infection in Denmark.
In addition, Ireland has maintained an average of about 4000 newly diagnosed cases in recent weeks, close to the highest level. The country's health department estimates that 11% of the newly confirmed cases are infected with the Omicron strain, up from 1% a week ago. At present, 18 cases of infection with Omicron strain have been confirmed in the country.
Norway's recent new cases and hospitalized cases have also broken records. So far, 958 cases infected with Omicron virus have been confirmed, of which 472 cases are in the capital Oslo.
Who acknowledges the limited impact of the vaccine on Omicron
Michael Ryan, head of the WHO health emergency project, said that in countries where the new coronal variant virus Omicron strain appeared, the strain spread at a very fast speed and caused a large number of cases. It is expected that the epidemic may reach its peak in a few weeks.
Ryan also pointed out that the new crown vaccine seems to have played a protective role against the Omicron strain. Who is currently collecting relevant experimental evidence to understand the effectiveness of the vaccine against the Omicron strain.
Due to a large number of variations of Omicron virus in the spike protein region of the mainstream vaccine, a number of preliminary research data show that the protective efficacy of most vaccines has been greatly attenuated.
Discovery health, South Africa's largest medical insurance provider, said that the effective rate of protection in the face of Omicron virus has been reduced to 33% for people who have completed two doses of Pfizer / BNT vaccine, but the effective rate is still 70% from the perspective of avoiding hospitalization and severe illness.
Tan Desai also said at the press conference on Tuesday that "vaccines alone can not cope with the epidemic". We also need to wear masks, maintain social distance and indoor ventilation, and adhere to strict hygiene habits. These things should be done, and we should find ways to do our best.
