Caption: We explain HIV and AIDS.
The human immune system constantly defends the body against disease.
It uses guards in the blood called T-cells to recognize any intruders and destroy them.
But instead of attacking the body, the human immunodeficiency virus, or HIV, attacks those T-cells themselves.
It turns the T-cells into copying machines
to produce more copies of the virus, then it eventually kills the infected T cells.
Without treatment,
on average after 8 years people with HIV develop AIDS
or acquired immunodeficiency syndrome.
By then there are not enough T-cells to fight various infections and diseases.
So not the virus directly, but the diseases, are ultimately fatal.
Humans first acquired HIV from blood contact with monkeys
and gradually transmitted it to more people through unprotected sex,
used syringes and childbirth.
AIDS remained unknown until a sudden outbreak among gay men in New York City and San Francisco in 1981.
Very quickly people began to develop the same unusual symptoms around the world.
The patients suffered rare forms of skin cancer, pneumonia or thrush, and few people survived.
Prejudice against homosexuality made research funding difficult,
and more and more people became ill.
What could be done?
Keep the virus from spreading.
It turned out that the best preventative measure is safe sex,
because condoms prevented the virus from infecting others.
Additionally blood banks began testing blood,
and new programs even distributed clean needles to drug users.
Finally in 1987 the first method of treatment against the virus was released,
the ancestor of combination therapy.
The drug is not yet a cure,
but it prevents the virus from multiplying and destroying the host’s immune system.
By starting treatment early,
people with HIV can now live long, healthy lives.
Unfortunately, many people still lack access to medicine,
especially in sub-Saharan Africa.
Over the last 30 years
about 36 million people have died, while 2 million more are infected each year.
Scientists have made a lot of progress, but they are still researching the cure.
You can also help end the AIDS crisis.
Play safe.
Test yourself.
Donate to support research, prevention and care.
And spread the word.
