By Patience Mthunzi

Nowadays, if we suffer headache, we swallow pill of aspirin. Swallowing pill is the most effective and painless way of delivery any medication in body. However, there is big problem in HIV patient. They usually take anti-HIV drugs. While it is good for lowering virus in blood by increasing the CD4 cell counts, it gives bad effects. It can make blood to become dilute, experts usually call it "drug dilution".

Fortunately, there is latest technology that we can deliver anti-HIV directly to the HIV-infected cell by using lasers. Such a breakthrough technology has been used for dentistry. In this cutting-edge technology, we use laser pulses to drill extremely tiny holes which open and close HIV-infected cells to deliver drug. Although now it is still testing in test tubes, but the final goal is applying to human body. In the future, such a technology can lead to complete eradication of HIV in the body.
