China opens world’s highest road tunnel

The world’s highest road tunnel opened to traffic in southwest China’s Sichuan Province on Tuesday, 15 years after the project was started.

The project, which cuts through Chola Mountain on the Qinghai-Tibet Plateau, consists of a 7-km tunnel and more than 5 km of auxiliary roads.

In Tibetan, the name Chola means mountains so high that eagles cannot fly over them. The peak stands at 6,168 meters above sea level and is covered with snow eight months of the year.

The tunnel is located above 4,000 meters. Its length, the thin air and low temperatures at that altitude all contributed to the complexity of the construction, said Wei Yanqing, chief designer of the tunnel.

A feasibility study started in 2002 and it took eight years for experts to finalize a plan before construction began in 2012.

The project cost about 1.28 billion yuan (196,900 U.S. dollars), according to Wang Qiang, head of the transport bureau in the Tibetan Autonomous Prefecture of Garze, which administrates the project area.

He said the two-way tunnel has a speed limit of 40 kph and takes around 10 minutes to pass through.

Previously vehicles spent more than two hours driving around the mountain on a road threatened by landslides, blizzards and slippery ice, he said.

Nationwide network winning battle against HIV

China’s central government spent 4.6 billion yuan (US$694 million) on HIV/AIDS control and treatment in 2016, a health official said yesterday.

The country has established an initial network of preventative services, in which government departments take the lead and the general public also participate, said Wang Guoqiang, deputy chief of the National Health and Family Planning Commission.

The network, covering both urban and rural areas, includes HIV testing, treatment and follow-up observations to prevent infected patients from transmitting the virus, Wang told the 2017 National Conference on HIV/AIDS in Guangzhou, a city in south China’s Guangdong Province.

Wang, who is also director of the HIV/AIDS prevention and control commission of the State Council, said China has almost entirely prevented the transmission of HIV through illegal blood transfusions, the sharing of needles and mother-to-child transmissions.

“The rapid spread of the virus in some particular areas has been greatly contained, the quality of life of HIV carriers has been improved, and social discrimination against the group has been reduced,” he said.

According to official data, China had nearly 420,000 people infected with HIV and 300,000 AIDS patients at the end of June. More than 221,000 people have died of the virus since records began.

Han Mengjie, with the Chinese Center for Disease Control and Prevention, estimated up to another 20 to 30 percent of HIV/AIDS patients in China are either not aware of their infection status or have not reported it, warning that the control of HIV/AIDS remains a challenge.

He said unprotected sex has become the main means of transmission, with the virus spreading among the elderly, youth and male homosexual populations.

“Prostitution and sexual activities spurred by drug abuse and social networking apps have posed threats for HIV/AIDS control,” he said. “Health departments will ensure implementation of preventive measures, find and treat as many infected as possible, and reduce the spread of HIV/AIDS to a low transmission rate.”

While the government puts the emphasis on prevention, scientists are seeking breakthroughs in treatment.

Wang Fusheng, an epidemic control specialist with the Chinese Academy of Sciences, and his team are studying immune deficiencies after CD4, a glycoprotein found on the surface of immune cells, becomes damaged.

Patients testing the therapy have found their symptoms alleviated or under control within two weeks, their CD4 cell count restored (an indication of the health of immune systems) and their weight significantly increased, he said.
