Sexually transmitted infections (STIs) are a widespread public health issue, with over one million curable cases acquired every day by people ages 15-49. The majority of these are asymptomatic, meaning they often go unnoticed. A wide range of bacteria, viruses, and parasites can be transmitted through sexual contact. While some STIs are curable, such as chlamydia, gonorrhea, syphilis, and trichomoniasis, others are viral and currently incurable, including herpes simplex virus (HSV), hepatitis B, human papillomavirus (HPV), and HIV.
Global Impact and Consequences
STIs have a significant and multifaceted impact on global health. In 2020, an estimated 374 million new infections of the four main curable STIs occurred. The consequences of these infections can be severe and extend beyond the initial illness. For instance:
- Increased HIV Risk: STIs like herpes, gonorrhea, and syphilis can make a person more susceptible to acquiring HIV.
- Reproductive and Maternal Health Issues: STIs transmitted from a mother to her child can lead to serious adverse birth outcomes, including stillbirth, low birth weight, and congenital deformities.
- Cancer: HPV infection is a major cause of cervical and other cancers, leading to over 311,000 cervical cancer deaths annually. Hepatitis B can also cause liver cancer.
- Infertility: Chlamydia and gonorrhea are leading causes of pelvic inflammatory disease (PID) and infertility in women.
Prevention and Treatment
Effective prevention and treatment strategies are crucial for controlling the spread of STIs.
- Prevention: Condoms, when used consistently and correctly, are highly effective at preventing the transmission of many STIs, including HIV. Vaccines are also available for hepatitis B and HPV, which represent major advances in prevention.
- Diagnosis and Treatment: Many STIs are asymptomatic, making regular screening and accurate diagnosis essential. While effective treatments exist for curable STIs (usually a single-dose antibiotic), the rise of antimicrobial resistance (AMR), especially in gonorrhea, poses a serious threat. For incurable viral STIs, antiviral medications can help manage the disease and reduce symptoms but do not cure the infection.
*Note: Health services for STIs often face challenges like limited resources and stigma, which can prevent people, particularly high-risk populations, from seeking care.
