A short History Behind HIV Incidents

AIDS primarily came to public awareness in 1981 with documents from Los Angeles that

some young homosexual men had exterminated from a formerly rare type of pneumonia. These men have experienced a ruthless deteriorating of the immune system that usually fights infectious illness. Shortly, these cases were related to a strange quantity of occurrences of a rare type of cancer, Kaposi's sarcoma, amid young homosexual males. Comparable boosts in such unusual diseases were proven among hemophiliacs and IV drug users.

Researchers quickly learned that the cause of AIDS was a previously unknown virus, which is now termed as human immunodeficiency virus (HIV), which obliterates certain WBCs of the immune system known as CD4 lymphocytes, one of the cells of the body's defense. An effective way to establish the string of transmission is case reporting, a procedure that needs health care workers to report specified illnesses to local, state, and national health officials. An example of such diseases is the HIV infection/AIDS, where it offers epidemiologists with an approximation of the incidence and prevalence of the disease. These details helps officials decide whether to investigate a given dosage.

Case reporting supplied epidemiologists with valuable leads concerning the origin and spread of HIV infection/AIDS. Actually, among the primmest clues about this infection came from reports of young males with Kaposi's sarcoma, formerly an illness of older males. Using these reports, epidemiologist started various studies of the patients. If an epidemiological study implies that a sizable enough segment of the population is afflicted with the condition, an attempt is then made to isolate and determine its causative agent. Identification is accomplished by a variety of microbiological methods. Identification of the causative agent often provides valuable information regarding the reservoir of the illness.

Once the chain of transmission is found, it is possible to apply control measures to stop the illness from spreading. These might include elimination of the source of infection, isolation, and segregation of infected individuals, the progression of vaccines, and as in the case of AIDS, education. In high-income countries, the availability of medication has made HIV infection no longer a certain death sentence. Regrettably, improvements in managing HIV incidents have resulted in a relaxed attitude toward safe sex practices. The fast mutation pace of HIV makes it difficult to create a vaccine that is effective against all forms of the virus. Another obstacle is the variety of routes by which HIV can be transmitted.

A highly effective vaccine would have to prevent transmission via diverse mucosal routes that is proving to be the intangible goal in exams with an immunodeficiency virus which have been performed in an animal similar to the internal structure of humans. Much progress has been made in the use of chemotherapy to inhibit HIV infections. To reproduce, the virus makes use if particular protease enzymes that cut proteins into pieces, which are then re-assembled into the coat of new HIV particles. Drugs called protease inhibitors inhibit this enzyme and are now in use. Visit your nearest STD clinic for more details regarding this illness.
