Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
Sexually Transmitted Infections01:26

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...
Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...
Genital Herpes01:23

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...
Amebiasis01:28

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...
Trichomoniasis01:18

Trichomoniasis

Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.

概括

人类免疫缺陷病毒 (HIV) 测试和咨询并没有显著减少随后的性传播疾病 (STD). 艾滋病毒阳性和艾滋病毒阴性患者都有很高的性传播疾病重复率,突出了公共卫生挑战.

科学领域:

  • 公共卫生 公共卫生
  • 传染性疾病 传染性疾病
  • 行为科学 行为科学

背景情况:

  • 人类免疫缺陷病毒 (HIV) 检测和咨询是重要的公共卫生干预措施.
  • 了解这些干预措施对后来的高风险行为,如性传播疾病 (STD) 的影响,对于有效的预防策略至关重要.

研究的目的:

  • 评估艾滋病毒检测和检测后咨询在减少后来的高风险行为,特别是性传播疾病的发生率方面的有效性.
  • 在测试和咨询后,比较艾滋病毒阳性与艾滋病毒阴性患者的性病发病率.

主要方法:

  • 在公共性传播疾病诊所对868名艾滋病病毒阳性和1104名艾滋病病毒阴性患者进行了病历审查.
  • 患者根据年龄,性别和艾滋病毒检测月份进行匹配,并在咨询后6-23个月内观察发生性传播疾病.
  • 在通知艾滋病毒测试结果和接受测试后咨询后,STD诊断被分类为等级.

主要成果:

  • 虽然71%的艾滋病毒阳性和63%的艾滋病毒阴性患者返回咨询,但在两组中都观察到大量的重复性传播疾病.
  • 艾滋病病毒阳性患者的可能性传播疾病发生率为3.9%,而艾滋病病毒阴性患者的发生率为10.2% (P < .001).
  • 艾滋病病毒阴性患者的比例高于艾滋病病毒阳性患者的比例 (3.3%),高于艾滋病病毒阳性患者 (1.5%),报告性病感染性伴侣 (P < .03).
