A highlights of the new Omicron XBB strain. 1.5 is spreading fast. It is said to have the strongest immune evasion among existing low-level mutant strains of Omicron, and US health authorities are nervous.

According to the US Centers for Disease Control and Prevention (CDC) on the 2nd (local time), as of the 31st of last month, XBB. It has been revealed that 1.5 account for 40.5% of all cases of new coronavirus (new type pneumonia) infection. That’s a figure that nearly doubled in one week from last month’s 21.7% to 24%.

XBB extension. 1.5 was called “Stealth Omicron” BA. It is a subordinate system of XBB derived from 2. After first being identified in India last August, XBB has led to a new spread in Singapore. Earlier in the United States, several sub-strains of omicron were confirmed simultaneously last fall, and it appeared to be engaged in a “dominant species competition,” but XBB. 1.5 is spreading rapidly to other variants. XBB extension. The detection rate of 1.5 reaches 75% of the total. “We expect XBB.1.5 to increase in the United States,” CDC’s Dr. Barbara Mahon told CBS.

Experts are worried about XBB. 1.5 strong immune evasion. XBB has been listed as the “worst new corona variant in existence” in terms of immune evasion, but XBB. It is an analysis that 1.5 exceeds this.

According to CNBC and other sources, virologist Andrew Pecos explained, “XBB.1.5 has an additional mutation that makes it more capable of binding to cells than other variants.” “XBB.1.5 is the most infectious and immune strain we know of so far,” said Yunlong Cao, a professor at Peking University.

Prior to this, researchers from Columbia University in the United States explained in a research paper published in the scientific journal Cell last month that “XBB substrains are threatening as they have strong resistance to booster injections of the Omicron vaccine.” Anthony Fauci, director of the US National Institute of Allergy and Infectious Diseases (NIAID), was once concerned that “XBB sub-strains reduce the immune effect provided by booster shots.”

According to The New York Times (NYT), on a daily basis, the average number of hospitalizations for the new coronavirus in the United States over the past seven days was 44,243, up 7% from two weeks ago. in the same period there were 5,303, with an increase of 11% compared to two weeks ago. However XBB. There is no evidence that 1.5 directly induces more severe symptoms.

Under these circumstances, the rapid increase in the number of new coronavirus infections in China is raising concerns about the emergence of new mutant strains, and countries around the world are one after another embarking on restrictions on tourists from China.

Since 3, Morocco has implemented a super bullish policy to completely block entry from China regardless of nationality. An increasing number of European countries are also restricting tourists from China. France and Spain, which had initially shown a cautious attitude towards Italy’s request to adhere to the regulation, have now made it mandatory to present a certificate certifying their negativity to the new coronavirus. The UK has also moved to make it mandatory for travelers from China to undergo a COVID-19 test before boarding a plane from the 5th of this month.

The European Union (EU) held a meeting on the 29th of last month to prepare joint measures for tourists from China among its 27 member countries, but they plan to hold another meeting this week as they failed to come to a conclusion.

So far, at least 14 countries, including South Korea, the United States, Japan, Italy, Spain, the United Kingdom, France, India, Australia, Canada, Taiwan, Malaysia, Bangladesh and Morocco have restricted Chinese tourists.

An animal cruelty controversy erupted when a camera captured a puppy dyed to look like Pikachu, the popular character from the Japanese anime ‘Pocket Monsters’, in the stands of American professional basketball (NBA).

According to the British newspaper Daily Star on the 27th (local time), a spectator who came to the basketball stadium of the Miami Heat and Minnesota Timberwolves that day brought a pet dog that looked like Pikachu, was dyed yellow, and the cheeks were dyed red. The tips of its ears are black and its back has a brown pattern similar to Pikachu’s.

The puppy was caught on camera during the match at the time, with a broadcaster remarking, “I don’t think the puppy was okay with that kind of tincture,” the paper said.

A video of a puppy dressed up as Pikachu went viral on Twitter and people all over the internet saw it and argued for and against.

Most people criticized the owner’s actions as animal cruelty, saying, “I’m sorry about the puppy,” “owner should be sent to jail,” and “owner seems to do anything for a ‘like’.” ”“When you dye a dog’s fur, it can cause a severe allergic reaction or stress,” she said.

On the other hand, some have countered that dyes made especially for puppies made from natural materials are not harmful to pet dogs. One person commented, “Dyeing a pet dog is like dressing up a cute baby.”

The South Korean government has released a photograph of the Kim Il Sung Square area in Pyongyang, North Korea, taken by the medium-sized satellite “National Satellite-1” on the 22nd. It has been three days since North Korea released a photo of central Seoul, purported to have been taken by a “reconnaissance satellite test product” on the 19th.

The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) released the satellite photos taken around Kim Il-sung Square on the same day, saying, “From the 23rd, we will open an exhibition of satellite photos taken by ‘National Land Satellite No. 1” at the National Land Development Exhibition Hall in Jung-gu, Seoul. .

Photos released by the Ministry of Land and Infrastructure show Kim Il-sung Square, the People’s University, the Central Museum of Korean History and the Museum of Korean Art in Pyongyang, North Korea. It is so clear that even a single tree planted in the square can be identified with the naked eye. Contrast with the blurry black and white photos of the North Korean side. The difference in the level of satellite technology between South and North Korea has become clear.

Black and white photos released by North Korea on the 19th show downtown Seoul and the port of Incheon. Large-scale structures such as the Han River Bridge and Incheon Port could be identified, but the outlines of the Yongsan Presidential Office and the triangular area were barely distinguishable. North Korea’s official media, the Korean Central News Agency released a satellite photo, saying, “North Korea’s National Agency for Space Development said on the 18th, the West Sea satellite launch site at Dongchang-ri, Cheolsan-gun, North Pyongan Province.In the final stages of testing critical reconnaissance satellite development, a color camera and two multispectral cameras for 20-meter resolution testing, a video transmitter, transmitters and receivers for each band, a controller and a storage battery were carried. The test was conducted with a satellite test product installed such as.

On the other hand, the new generation medium-sized 500 kg “National Satellite No. 1” satellite is equipped with an optical camera with a resolution of 0.5 meters in black and white and 2 meters in colour. The South Korean government launched the satellite from Kazakhstan in March last year.
