Fan Kelhoff, the technical director of the WHO, warned that it should not be excessively interpreted for new cases of new cases in the world.She pointed out that what is worth paying more attention is that global death cases have increased for six consecutive weeks.WHO said that many American countries have not adopted the transmission of fast action to suppress BA.1, so they must be prepared to face new mutant strains that may occur next.
(New York Composite Electric) World Health Organization said that the surge in the Omiko case seems to slow down in most parts of the world.However, scientists believe that the higher -contagious BA.2 subtype variants are leading to the increase in cases, and the reduction of detection times has blurred the global epidemic trend, and the actual transmission of the virus failed to reflect.
WHO data shows that from 7 to 13 this month, new cases of new cases worldwide were 19%less than the previous week, but Omikon's BA.2 subtype varieties have replaced primitive strains replaced by primitive strainsBA.1, in several Asian countries including China, India, Pakistan, Bangladesh, and the Philippines, they have become the main strains.Denmark was the first country to report BA.2 to BA.1.
Every five Omikon cases in the world are infected with BA.2 together.Scientists say that there is no evidence that BA.2 is more fatal than BA.1, and the existing vaccine seems to be able to effectively deal with BA.2.
WHO pointed out that in the Western Pacific region covering the Oceania, the Pacific Island nations and East Asian countries, the new cases of newly added last week increased by 19%.New cases in other areas are decreasing, but in some regions of Europe, including Slovakia, Latvia, and Belos, cases are still increasing.In the past two weeks, Russia's new cases have risen by 79%.
Vankelkhof, the technical director of the WHO, pointed out on Wednesday that the detection rate of crown diseases around the world is declining, which means that the confirmed cases of global notification may not truly reflect the transmission of the virus.
She warned that it should not be over -interpreted for the decline in new cases around the world.She then said that it is more worthy of attention to the number of global death cases for six consecutive weeks.
The most death cases in the East Mediterranean region, including the Middle East, are the most, followed by the Western Pacific.WHO said that in the Americas, many countries have not adopted rapid action to suppress the spread of BA.1. These countries must be prepared to face new mutant strains that may occur next.
Ati Anian, director of the WHO Panmei Health Organization, said: "The future trend of the epidemic is extremely uncertain ... a new mutant strain may appear at any time."
At the same timeWHO suggested that in some cases, countries with surge in cases can shorten the 14 -day isolation period proposed by WHO to seven days (if the detection is negative and asymptomatic) or 10 days (if not detected) to reduce it to alleviateNeed to serve the pressure.If the test cannot be performed, the asymptomatic can be used for shortening to shorten the isolation period.
WHO also said that countries may consider relaxing contactors to track.When tracing the contact of the diagnosis cases, people who are most likely to be infected such as medical personnel, such as medical staff and those who have not vaccinated or have potential diseases and may cause severe illnesses, are listed as priority tracking objects.
Some countries such as the United States, Germany, and Switzerland have shortened the isolation period to cope with the Omikon out of the epidemic.
