Sexually Transmitted Infections

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Contact-dependent Signaling

Contact-dependent Signaling

Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

In animal cells, gap junctions are formed...

Amebiasis

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...

Genital Herpes

Genital Herpes

Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...

Sex Linked Disorders

Sex Linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Area of Science:

Public Health
Epidemiology
Sexual Health

Background:

Traditional partner notification methods face challenges with evolving communication technologies.
Identifying and notifying sexual partners is crucial for sexually transmitted disease (STD) control.

Purpose of the Study:

To quantify factors associated with reporting sexual partners known only by email address (pseudonymous partners).
To evaluate the effectiveness of provider-initiated partner notification when only an email address is available for contact.

Main Methods:

A case-control study comparing individuals with pseudonymous email sexual partners to unmatched controls.
Odds ratios were used to quantify associations; provider partner notification success was compared between pseudonymous and traditionally contacted partners.

Main Results:

Factors associated with pseudonymous partners included male sex, white non-Hispanic ethnicity, prior STDs, multiple partners, and male-to-male sexual contact.
Provider partner notification via email successfully reached 49.7% of pseudonymous partners and 40.1% were evaluated.

Conclusions:

Internet-based communication, such as email, is a viable method for contacting and identifying at-risk sexual partners.
Failure to utilize these digital avenues may hinder public health interventions for a growing segment of at-risk populations.
