Gay Community Calls for End to US Policy Banning Blood Donations

 

Members of the gay community in the U.S. are calling for the lifting of a federal ban on blood donations by gay.

After this week's shooting at a gay nightclub in Orlando, Florida, thousands of homosexuals lined up to donate blood to survivors. However, they were turned away because of U.S. government rules that prohibit gay men from giving blood.

 
 

In the wake of the shootings, the policy is causing anger and outrage among gays.

 
 

The policy was put in place in the 1980s during the AIDS epidemic, and it barred gay and bisexual men from donating blood out of fear that they were at high risk of being HIV-positive and could contaminate the blood supply.

 
 

Public health advocates, who argued for lifting the blood donation ban last year, say the policy does not keep pace with some recent scientific developments to safeguard the blood supply against HIV.

 
 

Sean Cahill, director of health policy research at the Fenway Institute in Boston, said the revised policy is still unfair.

 
 

According to Cahill, the so-called nucleic acid test is now available to detect the presence of HIV in a pint of blood in less than two weeks, compared with the months it used to take. The test is performed on all blood samples to make sure they don't contain the virus.

Các thành viên của cộng đồng đồng tính ở Mỹ đang kêu gọi cho việc dỡ bỏ lệnh cấm liên bang về hiến máu của người đồng tính.
Sau khi chụp trong tuần này tại một hộp đêm đồng tính ở Orlando, Florida, hàng ngàn người đồng tính xếp hàng để hiến máu để sống sót. Tuy nhiên, họ bị từ chối bởi vì các quy tắc của chính phủ Hoa Kỳ cấm đàn ông đồng tính từ hiến máu.Trong sự trỗi dậy của các vụ nổ súng, chính sách này đang gây ra sự giận dữ và phẫn nộ về những người đồng tính.Chính sách này đã được đưa ra vào những năm 1980 trong đại dịch AIDS, và nó bị cấm đàn ông đồng tính và lưỡng tính từ hiến máu chỉ vì sợ rằng họ có nguy cơ cao bị nhiễm HIV dương tính và có thể gây ô nhiễm nguồn cung cấp máu.Bảo vệ sức khỏe công cộng, người ủng hộ cho dỡ bỏ lệnh cấm hiến máu năm ngoái, nói rằng chính sách này không bắt kịp với một số phát triển khoa học gần đây để bảo vệ các nguồn cung cấp máu chống lại HIV.Sean Cahill (đây là tên riêng), giám đốc nghiên cứu chính sách y tế tại Viện Fenway ở Boston, cho biết các chính sách đã được điều chỉnh vẫn không công bằng.Theo Cahill, xét nghiệm acid nucleic cái gọi là bây giờ đã có để phát hiện sự hiện diện của HIV trong một nửa lít máu trong vòng chưa đầy hai tuần, so với các tháng nó được sử dụng để thực hiện. Xét nghiệm này được thực hiện trên tất cả các mẫu máu để đảm bảo chúng không chứa virus.

Rachel Carson, an ecologist, a biologist, and a writer, was born in 1907 in Springdale, Pennsylvania. As a small girl, she was an avid reader and soon showed a keen interest in the natural world and writing. 1 She had her first story about animals published in a magazine when she was in the fourth grade. She graduated from Pennsylvania College for Women (now Chatham University) in 1929, studied at the Woods Hole Marine Biological Laboratory, and received her MA in zoology from Johns Hopkins University in 1932.

Initially, Rachel Carson worked for the US Bureau of Fisheries as a part-time science writer. 2 Part of her job was to interest the public in marine and freshwater biology via radio programmes. She then spent the next few years serving as a marine scientist and editor for the US Fish and Wildlife Service. There, she became famous for her writings on environmental pollution and the natural history of the sea, 3 She warned the public about its negative long-term effects. Climate change, rising sea-levels, melting Arctic glaciers, decreasing animal populations are part of her work. In her most influential book, Silent Spring (1962), Rachel Carson strongly disapproved of the widespread use of pesticides such as DDT. 4 Firstly, Silent Spring suggested a much-needed change in people's way of life and called for new policies to protect humans and the environment. She then was criticised by the chemical industry and some government officials, but never gave up. 5 The book eventually prompted a change in national policy, leading to the enactment of a national ban of pesticides on agricultural farming. Additionally, it helped spark the environmental movement, resulting in the establishment of the United States Environmental Protection Agency. That's why she was called the mother of modern ecology.

Rachel Carson died of breast cancer in 1964. However, her work continues to inspire new generations to protect all the living world.

Tạm dịch

Rachel Carson, nhà sinh thái học, nhà sinh vật học và nhà văn, sinh năm 1907 tại Springdale, Pennsylvania. Khi còn là một cô gái nhỏ, cô ấy là một người ham đọc sách và sớm thể hiện sự quan tâm sâu sắc đến thế giới tự nhiên và viết lách. Cô ấy có câu chuyện đầu tiên về động vật được đăng trên một tạp chí khi cô ấy học lớp bốn. Cô tốt nghiệp Đại học Phụ nữ Pennsylvania (nay là Đại học Chatham) vào năm 1929, học tại Phòng thí nghiệm Sinh học Biển Woods Hole và nhận bằng Thạc sĩ về động vật học tại Đại học Johns Hopkins vào năm 1932.

Ban đầu, Rachel Carson làm việc cho Cục Thủy sản Hoa Kỳ với tư cách là một nhà văn khoa học bán thời gian. Một phần công việc của cô là thu hút sự quan tâm của công chúng đến sinh vật biển và nước ngọt thông qua các chương trình phát thanh. Sau đó, cô đã dành vài năm tiếp theo với tư cách là nhà khoa học biển và biên tập viên cho Cơ quan Cá và Động vật hoang dã Hoa Kỳ. Ở đó, cô trở nên nổi tiếng với những bài viết về ô nhiễm môi trường và lịch sử tự nhiên của biển, Cô cảnh báo công chúng về những tác động tiêu cực lâu dài của nó. Biến đổi khí hậu, mực nước biển dâng cao, băng tan ở Bắc Cực, giảm quần thể động vật là một phần công việc của cô. Trong cuốn sách có ảnh hưởng nhất của mình, Silent Spring (1962), Rachel Carson cực lực phản đối việc sử dụng rộng rãi thuốc trừ sâu như DDT. Đầu tiên, Silent Spring đề xuất một sự thay đổi rất cần thiết trong cách sống của mọi người và kêu gọi các chính sách mới để bảo vệ con người và môi trường. Sau đó, cô bị chỉ trích bởi ngành công nghiệp hóa chất và một số quan chức chính phủ, nhưng không bao giờ bỏ cuộc. Cuốn sách cuối cùng đã thúc đẩy một sự thay đổi trong chính sách quốc gia, dẫn đến việc ban hành lệnh cấm toàn quốc về thuốc trừ sâu trong canh tác nông nghiệp. Ngoài ra, nó đã giúp châm ngòi cho phong trào môi trường, dẫn đến việc thành lập Cơ quan Bảo vệ Môi trường Hoa Kỳ. Đó là lý do tại sao cô được gọi là mẹ của hệ sinh thái hiện đại.

Rachel Carson qua đời vì bệnh ung thư vú vào năm 1964. Tuy nhiên, công việc của cô vẫn tiếp tục truyền cảm hứng cho các thế hệ mới bảo vệ tất cả thế giới sống.
