Jakarta. Our nose is the gateway entry of various types of germs, especially viruses. Not only the flu viruses that enter through the nose, the herpes virus that can damage the brain and trigger a variety of neurological disorders are also entering through the respiratory tract.

This type of herpes virus that damages the brain is the Human Herpes Virus Type-6 or HHV-6 which is often abbreviated. Judging from the structure Deoxyribo Nucleic Acid (DNA), the virus is still allied with the genital herpes virus that attacks the mouth and genitals.

The difference is, the attack HHV-6 does not trigger the disorder on the surface of the skin but deep inside the central nervous system in the brain. The result is brain damage, among others, multiple schlerosis, encephalitis, roseola (on the skin of a child triggers a rash accompanied by fever) and epilepsy.

The way this virus reaches the brain is not yet known with certainty, but recent research indicates that the nose and the airways become one of the gates to enter the human body. From the nose, the virus down the nervous system until it reaches the brain.

Neurovirologi experts from the National Institute of Neurological Disorders and Stroke, Dr. Steven Jacobson reveals that after the autopsy on a corpse schlerosis multiple patients. From the findings of HHV-6 in the brain, its concentration is most prevalent in the olfactory center.

Dr. Jacobson relate it to previous results of other studies, that some patients experienced multiple schlerosis decreasing ability to smell odors. Presumably, viral infection causes damage to the olfactory nerve before finally reaching the brain.

This virus has been known since a long time, even most of us have been infected since childhood. Most of the really tame, but still need to watch out because some people have different tolerances and the infection can lead to brain damage,” said Dr. Jacobson was quoted as saying from LiveScience, Tuesday (08/09/2011).

Dr. Jacobson’s research results have been published recently in the online journal, Proceedings of the National Academy of Sciences.
