Aids todayAids is caused by a virus called HIV which enters a person’s blood and attacks the body’s immune system．There is no cure for HIV or Aids, and after a person has been infected, he or she will always carry the virus．Sometimes, infected people have no outward symptoms．
HIV and Aids are spreading across the world at a frightening rate, with about 14,000 people being infected daily．The virus is spread in three ways－through unprotected sex, blood-blood contact and mother-to-child transmission．Unprotected sex is the most common way that the virus is spread, accounting for 75 percent of adult infections worldwide．
Although many people are familiar with Aids and how it is transmitted, more than a few people hold the view that HIV and Aids are an African problem because the infection rates there are very high．However, HIV and Aids are a problem all over the world．Since the disease was discovered in the 1980s, it has become a serious problem in many places, infecting over 60 million people worldwide．According to the World Health Organization estimates from 2005, more than 4 million children had died from Aids, and more than 14 million children had lost their parents to Aids．All of this makes it clear that something must be done to stop this deadly disease．
The government is working hard to control the Aids epidemic and has opened labs to test and monitor the disease．In 2003, the government also started providing free drugs for Aids patients in need．
The United Nations has been very involved in fighting Aids and HIV around the world for many years now．UNAIDS, an organization founded in 1996 helps prevent the spread of Aids．The work includes providing infected people with help from doctors and testing for people．The organization also offers programs that teach Aids prevention to young people and sets up treatment centers．
Every year when the Italian artist Michelangelo’s (1475－1564) birthday comes around, computer users all over the world are filled with fear and use their computers with care. Some may even choose not to turn on their computers on March 3rd. All this fear and care are just because a deadly computer virus(病毒) is ready to cause damages on that day.
What’s a computer virus then? Why do people get so afraid of it?
A computer virus is, in fact, a little program that is put into other programs and that does something bad. It is called a virus because, like any real-life viruses such as AIDS virus, it reproduces(繁殖) itself. And when these programs are run, the virus is brought to life. It hides itself in your computer system waiting for the right moment to make damages. And at the same time it keeps producing itself by copying itself onto other programs.
The Michelangelo virus waits until the artist’s birthday comes around, and then it will wake up to do very bad things like destroying you files. So next time when you turn on your computer, look out for computer viruses!
