Australia’s early and widespread use of clean-needle programs seems to have kept HIV rates among injection-drug users in check over the long term, a study showed.
In 1986, several years after HIV and AIDS came to widespread attention, Australia set up publicly funded programs to provide injection-drug users with clean needles and syringes, an attempt to prevent needle sharing and head off an epidemic of HIV, the virus that causes AIDS, among drug users.
In many countries, needle exchange programs allow drug users to trade in used needles for new ones, but in Australia users are simply given new ones.
Libby Topp, at the National Centre in HIV Epidemiology and Clinical Research in Darlinghurst, Australia, and other researchers found that between 1995 and 2009, the rate of HIV among participants in Australia’s needle programs held steady at about 1 percent.
According to the study, reported in the journal AIDS, the pattern of infections also mirrored what is seen in the general Australian population — that is, the majority were among gay and bisexual men.
“There has never been a significant, generalized outbreak of HIV among people who inject drugs in this country,” Topp said. “What our results show is that in a country where needle and syringe programs were introduced early and on a widespread basis, HIV transmission never became a problem among injectors.”
Topp told reporters in an e-mail that, based on other research, the 1 percent HIV rate is true of all injection-drug users in Australia, and not only those who use the needle and syringe programs.
By contrast, an estimated 16 percent of injection-drug users in the US are living with HIV, while in Russia that figure is 37 percent.
Reporters Without Borders has accused the Algerian government of taking advantage of the COVID-19 pandemic to “settle scores” with independent journalists, including those covering long-running anti-government protests. In a statement signed with Algerian non-governmental organizations, the watchdog on Thursday called for the immediate release of its correspondent, Khaled Drareni, who has been in pretrial detention since Sunday after being charged with inciting an unarmed gathering and endangering national unity. Drareni has been arrested several times for covering the “Hirak” anti-government protests held in the capital, Algiers, every Friday since February last year. Imprisoning people during a pandemic is “an act of physical endangerment,”
Vietnam has lodged an official protest with China following the sinking of a Vietnamese fishing boat that it said had been rammed by a Chinese maritime surveillance vessel near islands in the South China Sea. The Vietnamese fishing vessel, with eight fishermen onboard, was fishing near the Paracel Islands (Xisha Islands, 西沙群島) on Thursday when it was rammed and sunk by the Chinese vessel, the Vietnamese Ministry of Foreign Affairs said in a statement posted on a government Web site yesterday. All of the fishermen were picked up by the Chinese vessel alive and were transferred to two other Vietnamese fishing vessels
DIVIDED YOUTH: There is a belief that overseas students see themselves as superior, which is compounded by perceptions of their extreme wealth and multiple nationalities Chinese students flying home from overseas to escape the COVID-19 pandemic face a frosty reception from sections of the public who view them as wealthy, spoiled — and potentially contaminated. The number of officially reported cases in China has dwindled dramatically over the last month, but the country is now taking drastic steps to try and stem a second wave of infections brought in from abroad. With most international flights canceled and nearly all foreigners barred from entering the country, the vast majority of returnees are Chinese nationals, including many students. The situation has exposed animosities over class and privilege in Chinese society,
An Australian graduate student arrested for spying and expelled from North Korea last year said that he was threatened with a firing-squad execution and told not even US President Donald Trump could save his “sorry arse.” Among the crimes Alek Sigley was accused of committing was posting a picture of a toy tank on Instagram, which his interrogators told him was military espionage. Sigley, 30, was studying for a master’s degree in Korean literature at Kim Il Sung University in Pyongyang when he went missing in June last year, sparking alarm. A fluent speaker of Korean, he had written articles for several publications
