For all major STDs, the incidence is much greater in men who have sex with other men than in the heterosexual population.
For a number of STDs, the clinical manifestations overlap significantly, thus preventing a definitive diagnosis without microbiologic examination.The Agency acknowledges that the advice and recommendations set out in this statement are based upon the best current available scientific knowledge and medical practices, and is disseminating this document for information purposes to both travellers and the medical community caring for. TD is mainly acquired through the ingestion of food and beverages contaminated efficacy of their products only when used in accordance with the product monographs or other similarly approved standards.
To aid in narrowing the differential diagnosis, STDs are commonly categorized based on clinical presentation. This article will focus on diseases characterized by genital ulcers, as well as those characterized by urethritis and cervicitis.
Diseases Characterized by Genital Ulcers In the United States, most sexually active individuals who have genital ulcers of an infectious etiology have genital herpes, syphilis, or chancroid. The distribution of these diseases throughout the country differs, based on geography and patient population.
Importantly, each has been associated with an increased risk of acquiring other sexually transmitted diseases, including HIV infection. This article will deal specifically with the presentation, manifestations, and treatment of genital herpes and syphilis.
Genital Herpes The word herpes comes from the Greek, meaning "to creep, and it has been used in medicine since antiquity. Genital herpes is caused by the herpes simplex virus HSV serotype 1 or 2.
The majority of cases are caused by HSV-2. Infection with HSV-2 is lifelong, and currently antiviral therapy is not curative.
This contact includes sexual contact with a person with active lesions, more commonly, sexual contact with one who is asymptomatic but is shedding virus in genital secretions.
Other modes of transmission include autoinoculation and neonatal transmission.
It is important to note that the overwhelming majority of genital herpes is transmitted when a person feels well and appears normal but is asymptomatically shedding virus. Cells lyse, new virions are released, and these virions travel via lymph to nodes.
Depending on a variety of host factors, the virus either will disseminate through the blood and seed viscera or the central nervous system CNS, or it will remain latent in local nerve roots.
Infection is lifelong, because the virus cannot be eradicated from the body. Histopathology classically shows multinucleated giant cells with intranuclear inclusions.
The virus becomes latent and can periodically reactivate. Recurrences of genital herpes are to be expected, but currently there is no way to predict for an individual patient when or how often such recurrences will appear.
The incubation period for genital herpes can be highly variable, ranging from 7 days to several years. The lesion will progress and rupture over the course of the next week to become a cluster of moist, shallow ulcers.
The ulcers begin to heal within 2 weeks, forming dry crusts.
By day 21, lesions are generally healed, and viral shedding has decreased significantly.
