一 |     　　讯 水利部8月14日消息，受台风“白海豚”残余环流和冷空气及季风槽等影响，预计8月14—16日，江苏南部、上海、浙江、安徽东部南部、江西大部、福建南部西部、广东中部东部等地将有大到暴雨；其中，江苏南部、浙江东北部、广东中部等地局部将有大暴雨。    Washington, Oct 18 (UNI) Scientists at Boston University has developed a new Covid-19 strain which resulted in an 80 per cent kill rate in mice.

The variant, a combination of Omicron and the original virus in Wuhan, killed 80 per cent of the mice infected with it, the university said. When mice were only exposed to Omicron, they experienced mild symptoms, the New York Post said.

A team of scientists from Florida and Boston at the school’s National Emerging Infectious Diseases Laboratories conducted the research.

They extracted the spike protein from Omicron and attached it with the strain first detected at the onset of the pandemic that began in Wuhan, China. They then documented how the mice reacted to the hybrid strain, according to the New York Post report.

“In…mice, while Omicron causes mild, non-fatal infection, the Omicron S-carrying virus inflicts severe disease with a mortality rate of 80 percent,” they wrote in a research paper.

The new strain has five times more infectious virus particles than the Omicron variant, researchers said.

二 | 建议持续关注水情预警信息，暴雨时尽量减少外出，避开积水路段、地下通道、深山峡谷等危险区域；驾车出行主动绕行漫水桥和积水低洼地段，切勿强行涉水；居住在山区和河湖岸边的群众要远离低洼空间，提前做好转移避险相关准备。
