New COVID Sub-Variant BA 2.75 Detected in India, WHO Says_我的网站

A |     The World Health Organization (WHO) has revealed that the new BA.2.75 sub-lineage of the Omicron variant of COVID has been detected in India.,"In Europe and America, BA.4 and BA.5 are driving waves. In countries like India, a new sub-lineage of BA.2.75 has also been detected, which we're following," WHO Director-General Tedros Adhanom Ghebreyesus said at a press briefing on Wednesday.,He said that new COVID cases reported worldwide have spiked by nearly 30 percent.,Experts say the BA.2.75 variant includes new mutations in the spike protein, in addition to mutations that are already present in the Omicron variant.,This allows it to evade several antibodies and can infect people who have been vaccinated or infected previously. The detection of BA.2.75 has led scientists across the globe to dive deep into the research to learn more about the new variant and the possibility of another COVID wave.,In India, the BA.5 sub-variant has been detected in the states of Tamil Nadu, Karnataka, West Bengal, Maharashtra, Telangana, Delhi, Haryana, Gujarat, and the Ladakh union territory as well.,WHO Chief Scientist Soumya Swaminathan said in a video posted on Twitter that there has been an emergence of a sub-variant called the BA.2.75, "first reported from India and then from about 10 other countries.",Swaminathan said there are still limited sequences available of the sub-variant to analyze, "but this sub-variant seems to have a few mutations on the receptor-binding domain of the spike protein. So obviously, that's a key part of the virus that attaches itself to the human receptor.","So we have to watch that. It's still too early to know if this sub-variant has properties of additional immune evasion or indeed of being more clinically severe. We don't know that," she added.,Last week, Dr. Shay Fleishon, an Israeli scientist, claimed that a new coronavirus variant had hit 10 Indian states and sparked concerns of a fourth wave of the COVID-19 pandemic.,The current daily positive test rate is, however, is around 4.32 percent, down from around 16-17 percent in January 2022, the peak of the first Omicron wave.。

    The "flying lifebuoy" debuts during a water rescue drill in Hangzhou, East China's Zhejiang Province. Photo: Official WeChat account of the Hangzhou governmentA "flying lifebuoy" recently made its debut during a water rescue drill organized by police in Hangzhou, East China's Zhejiang Province, as the city explores multiple high-tech solutions to improve emergency response in water accidents. The device received praise from a Chinese Foreign Ministry spokesperson. 
According to a report posted on the official WeChat account of Hangzhou, an orange lifebuoy took off from the shore during the drill, flew toward a person who had fallen into the water, and landed on the water surface. Even when the person climbed onto it, the device remained stable and continued to float.
Minutes later, rescuers arrived and brought the person to safety. The lifebuoy then took off again and returned to its original location.
The device, officially called an AI intelligent flying rescue robot, is designed to provide rapid assistance in open waters where rescue boats may take time to arrive. Equipped with an autonomous navigation system, it can fly to people in distress, provide buoyancy support, and return automatically after completing its mission.
The drill featured multiple water rescue scenarios and tested several intelligent rescue technologies. Drones were used to drop inflatable lifebuoys above people in distress, which quickly inflate upon hitting the water to provide temporary buoyancy.
Another system combined an unmanned boat and drone for rescue operations in dangerous waters. The drone searches and locates people in need, while the boat navigates autonomously to assist the rescue. The drone can also provide lighting for nighttime searches, according to the report.
Chinese Foreign Ministry spokesperson Lin Jian highlighted in a social media post on August 14 that the AI-powered device is "technology that could help save lives."
