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.

Mr Quang: Good morning, class. Today’s lesson will start with Mai and Nam’s talk about some of the causes and consequences of global warming. Would you like to go first, Mai?

Mai: Yes, thank you. First, let me remind you what global warming refers to - it’s the increase in the earth's temperature because of certain gases in the atmosphere.

Nam: Exactly. These gases are mainly produced through human activities. For example, burnt for energy, fossil fuels release large amounts of carbon dioxide into the atmosphere.

Mr Quang: But how do these gases make the earth warmer?

Mai: Well, they act like the glass in a greenhouse. Trapping too much of the sun’s heat, they stop it from escaping back into space. This makes the planet hotter and hotter.

Nam: That's right. That’s why these heat-trapping pollutants are known as greenhouse gases, and their impact is called the greenhouse effect.

Mai: Global warming is also linked to rising sea levels. As temperatures rise, polar ice caps melt faster, adding more water to oceans. Higher sea levels can also lead to floods.

Nam: Each year, the consequences of global warming become more serious, and its negative impact on the environment and people gets stronger.

Mr Quang: Good job! Thank you for sharing the information.
