diagnosing HIV infection

Further in 1985, a blood test was formulated which helped in identifying if a person was carrying HIV. Since 1985, this blood test is used effectively for diagnosing HIV infection. Some more tests were also found to help in diagnosing the virus and the disease using the saliva and urine.

During first few years of the detection of the new disease AIDS, all the possible reasons of spread of the disease were unknown. This helped the disease spread from one infected person to another. Back in the decade of 60's, there were very rare chances of a disease spreading across continents or countries. It was possible only when one person traveled from one country to another and carried the disease knowingly or unknowingly. The spread of AIDS is also said to be related with the same situation. It is said that when flight attendants used to fly across the seas, they had many sex partners in almost all the countries they visited. This helped AIDS spread from Africa and allowed it to enter in America.

After few years, all the possible reasons which helps AIDS virus to spread from one person to another were revealed, such as blood transfusion from an infected person to a healthy person, sexual intercourse between infected person and a healthy person, use of syringe etc. Right from the time of outbreak of the virus, it has infected over 50 million people and killed about half of the same till today (The number of people infected and killed due to AIDS might change, as there is a huge difference in official and unofficial data). But the right cure for the virus has not yet been discovered.
