#STIs

Sexually transmitted infections are rising among older Europeans. This trend could affect Thailand through travel and ageing demographics.

Health authorities report rising diagnoses of gonorrhoea, chlamydia, and syphilis in people aged 45 and older. The trend appears across the UK, France, Denmark, and the EU (ECDC, UKHSA) (ECDC syphilis report 2023; UKHSA STI data tables 2014-2023).

The number of common bacterial STI diagnoses in Britons aged 65 and over rose sharply from 2014 to 2023. UK figures show 576 diagnoses in 2014 and 1,649 in 2023 for gonorrhoea, chlamydia, and syphilis combined (UKHSA data).

As Thailand’s population ages and international travel resumes post-pandemic, a troubling trend emerging across Europe demands immediate attention from Thai health authorities. Sexually transmitted infections are surging among Europeans aged 45 and older, presenting a clear warning for Thailand’s own rapidly aging society.

Recent surveillance data from European health authorities reveals alarming increases in bacterial STIs among older adults. In the United Kingdom alone, diagnoses of gonorrhoea, chlamydia, and syphilis in people over 65 nearly tripled between 2014 and 2023, jumping from 576 cases to 1,649 cases. This dramatic rise reflects a continent-wide pattern that has caught public health experts off guard.

Florida lawmakers are debating a bill that would require parental consent for minors to receive treatment for sexually transmitted infections (STIs), contraception and even to complete certain school health surveys — a proposal critics say comes as teen STI rates in the state are at their highest in more than a decade and could push vulnerable young people away from lifesaving care. The bill, SB 1288, advanced through a Senate Pre‑K‑12 committee in late March after heated testimony from sexual‑assault survivors, public‑health advocates and clinicians who warned that removing confidential access risks higher rates of untreated infections and unintended pregnancies — outcomes that public‑health research links to policies that restrict adolescent confidentiality in sexual and reproductive health services (Florida Phoenix; Tallahassee Democrat). The debate in Florida is a stark reminder for Thailand that policy changes limiting adolescents’ confidential access to STI testing, treatment and contraception can have measurable public‑health consequences — especially where sex education is inconsistent and cultural stigma around adolescent sexuality remains strong.

A new snapshot of Gen Z family planning finds young adults are delaying parenthood into their late 20s and, worryingly, a significant share are relying on the withdrawal or “pull-out” method as a primary form of birth control. The findings, drawn from a survey by pregnancy test brand First Response and women’s media platform Her Campus and reported by the New York Post, underscore a generational rethinking of when to have children — and a risk calculus around contraception that health experts say could backfire. For Thailand, where the birth rate has plunged to historic lows, the mix of delayed childbearing and inconsistent contraceptive protection holds lessons for sex education, public health, and demographic policy.

Alarming new research reveals that Generation Z adults are increasingly delaying parenthood while simultaneously relying on ineffective contraceptive methods, creating a perfect storm of reproductive health risks that could significantly impact Thailand’s already plummeting birth rates. A comprehensive survey conducted by pregnancy test manufacturer First Response in collaboration with women’s media platform Her Campus discovered that nearly 37% of young adults favor the withdrawal or “pull-out” method as their primary contraceptive approach, despite medical evidence showing this technique fails for approximately one in five couples annually. These findings arrive at a critical moment for Thailand, where birth rates have collapsed to historic lows below population replacement levels, requiring urgent attention to both reproductive health education and family planning support systems.

For many women, a bit of cramping or an abnormal discharge is often dismissed as nothing more than “just another bad period” or a routine infection. However, recent medical research warns that these subtle symptoms could, in fact, be the body’s urgent distress call about a condition far more severe than it appears: pelvic inflammatory disease (PID). Frequently ignored and frequently misunderstood, PID represents a significant, silent threat to fertility—a risk that is often only discovered when women try to conceive, sometimes years after the initial, nearly invisible damage has been done. In the United States alone, more than one million women are estimated to be affected by PID each year, making it one of the leading causes of preventable infertility (Rolling Out).

A mild cramp or a touch of fatigue might seem like an everyday nuisance, but new research highlights that dismissing these subtle signs could have serious long-term effects on women’s fertility. Pelvic Inflammatory Disease (PID)—an often silent and preventable disorder affecting the female reproductive system—remains one of the leading causes of infertility, yet public awareness in Thailand and around the globe is worryingly low (Rolling Out).

This news has wide significance for Thai readers, as reproductive health is intrinsically bound not only to personal wellbeing but also broader demographic trends and social stability. While Thailand has made progress in expanding access to reproductive healthcare, conditions like PID—often overshadowed by more high-profile women’s health issues—have a hidden toll, affecting families, livelihoods, and the nation’s future. According to the Department of Obstetrics and Gynecology at Chiang Mai University, PID is frequently underdiagnosed in Thailand because of its subtle presentation and the stigma around sexual health conversations (med.cmu.ac.th).

Sexually transmitted infections (STIs) are fast emerging as one of the most serious yet often overlooked threats to women’s health and fertility globally, according to the latest research highlighted by experts. Mounting evidence indicates that untreated STIs not only cause acute symptoms but can lead to long-term reproductive health complications, with grave implications for women across all regions—including Thailand.

Recent research reviewed by international health authorities reveals an alarming surge in the incidence of common STIs, such as chlamydia, gonorrhea, and syphilis. These infections, when left untreated, can progress silently to cause pelvic inflammatory disease (PID) and subsequent infertility, especially among women of reproductive age. According to a 2024 review in Drug Topics, millions of women each year are at risk of permanent reproductive harm due to preventable and treatable infections.
