We are halfway through 2025 and the Philippines continues to grapple with a complex and evolving landscape of sexually transmitted infections (STIs). While various STIs are present, the most pressing concern remains the alarming rise in HIV cases, particularly among younger demographics. This trend underscores the urgent need for intensified public health interventions and sustained community engagement. 

Recent data from the Department of Health (DOH) for the first quarter of 2025 paints a stark picture. The country recorded over 5,100 new HIV cases from January to March, alongside 145 HIV/AIDS-related deaths. This represents a significant increase, with an average of approximately 57 new cases detected daily, marking a 50% rise compared to the same period last year. A crucial detail is that nearly 80% of these new cases are among individuals aged 15 to 34, highlighting a growing prevalence among young populations. Furthermore, sexual contact remains the predominant mode of transmission, with male-to-male sexual contact accounting for the majority of these infections. 

Beyond HIV/AIDS, other common STIs like Chlamydia, Gonorrhea, Syphilis, Herpes, and Human Papillomavirus (HPV) continue to be public health concerns. Many of these infections can be asymptomatic, making regular testing crucial for early detection and preventing further spread.
