Genital Herpes Essay -- essays research papers

I have infected 45 million Americans and pass on infect 1 million more Americans each year. Who am I?Herpes, from the ancient Greek meaning to creep or crawl, is the name of a family of computer viruses of which herpes simplex virus 1 and herpes simplex virus 2 (HSV-1 and herpes simplex 2) argon the most serious human pathogens. HSV-1 is normally associated with orofacial contagions and encephalitis, whereas HSV-2 usually causes genital infections and can be transmitted from infected mothers to neonates. Both viruses establish latent infections in sensory neurons and, upon reactivation, cause lesions at or near point of entry into the body. While HSV-1 and HSV-2 are polar viruses, under a microscope, HSV-1 and 2 are virtually identical, sharing approximately 50% of their desoxyribonucleic acid and are toughened similarly. HSV-1 and HSV-2 contain a large double-stranded DNA molecule. HSV is deoxyguanosine monophosphate negative, consists of 162 capsomers and replication takes pl ace within the nuclei of eukaryotic cells. The HSV virion has four parts an electrondense meat containing viral DNA an icosapentahedral capsid a tegument-an amorphous layer of proteins that put off the capsid and an envelope. HSV-1 and HSV-2 encode at least(prenominal) 84 different polypeptides. Each protein does many things, hence HSV genes can encode some(prenominal) hundred different functions. To initiate infection, HSV attaches to at least three different classes of cell-surface receptor and fuses its envelope with the plasma membrane. The capsid, minus its envelope, is transported to the nuclear pore, through which it releases viral DNA into the nucleus. HSV replicates by three rounds of transcription that yield alpha (immediate early) proteins that in general regulate viral replication beta (early) proteins that synthesise and package DNA and gamma (late) proteins, most of which are virion proteins. Of the 84 known polypeptides, at least 47 are not needed for viral repli cation in cultured cells. These 47 genes are not completely dispensable. Some equilibrise cellular genes that are not expressed in terminally secernate cells others alter cellular metabolism to ensure high virus yields. variance viruses lacking these genes cannot survive in nature.The symptoms of genital herpes vary wide form someone to person. Some people have severe symptoms (such as many painfu... ...Unlike the culture method, this test does not require growing the virus but rather seeks to identify herpes by the presence of antigens, fragments of the virus that are know to stimulate the immune response. Herpes cannot be cured. at one time someone is infected with either virus, it cannot be cleared from the human body. venereal herpes is usually treated with antiviral drugs such as acyclovir (Zovirax), Famciclovir (Famvir), and Valacyclovir (Valtrex) to help keep the virus in an inactive state and counter most outbreaks but again does not cure a person from the virus. Dur ing an active herpes episode people should follow a fewer key steps to speed healing and avoid spreading the infection to other places on the body or to other people remark the infected area clean and dry to prevent other infections from evolutionTry to avoid touching the soresWash you hands after advert with the soresAvoid sexual contact from the time the first symptom is matte up until the sores are completely healed, that is, the scab has fallen off and new pare down has formed where the sore was.
