It comes without warning.It destroys people’s bodies.It kills almost 5,000 people around the world every day.This is AIDS – one of the most dangerous human diseases on the Earth.
December 1 is World AIDS Day.This year’s theme is “Getting to Zero:zero new HIV infections(傳染), zero discrimination(歧視)and zero AIDS – related deaths”.
AIDS stands for Acquired Immunodeficiency Syndrome(獲得性免疫缺陷綜合癥).It is caused by HIV – a virus(病毒).HIV travels in people’s blood and affects T cells(細(xì)胞), a type of cell that helps the body fight diseases.It may take years for the virus to harm enough T cells for the infected person to get sick and develop AIDS.
HIV and AIDS spreads through blood-to-blood contact, sharing needles or having blood transfusions.A mother with HIV can give the virus to her unborn baby.Unsafe sex can also spread AIDS.
Right now there is no cure(治療)for HIV or AIDS.However, new treatments can help people with the virus live longer.The “AIDS Cocktail(雞尾酒療法)”, uses several drugs mixed together like a cocktail.It can help people with HIV to live longer.
On World AIDS Day, people wear red ribbons to show they care about HIV and AIDS.American artists thought up the red ribbons in 1991.They chose red because it is bold and visible – symbolizing(象征)passion, a heart and love.
How much do you know about AIDS?
Q:Can you get AIDS from shaking hands with someone who has AIDS?
A:No.The HIV virus cannot live outside the human body.So social contact such as hugging(擁抱)or kissing an AIDS patient cannot give you AIDS, either.
Q:Can you get AIDS if mosquitoes(蚊子)bite(叮咬)you?
A:No.Mosquitoes do take blood from people but they do not exchange blood between people.
Q:If a dog bites someone with AIDS, and then bites you, can you catch AIDS?
A:No.AIDS only affects humans.Animals cannot catch this illness from people, and people cannot catch it from animals.
