Genital herpes is a sexually transmitted infection caused by herpes simplex virus (HSV) type 1 or 2. It affects at least 500 million people worldwide and is a lifelong condition involving initial infection and periodic reactivation with variable viral shedding. There are no vaccinations for the prevention of HSV, and routine serologic screening is not recommended in asymptomatic individuals. ⋯ Complications of genital herpes include encephalitis, meningitis, and urinary retention. During pregnancy, antiviral suppression is recommended starting at 36 weeks of gestation in patients with a known history of genital herpes. Elective cesarean delivery should be offered to patients with active lesions to reduce neonatal exposure to HSV.

Prostate cancer is the most diagnosed noncutaneous malignancy and the second most common cause of cancer death among men in the United States. Risk factors include older age, family history of prostate cancer, and Black race. Screening via prostate-specific antigen testing may lead to a small reduction in prostate cancer-specific mortality, with no reduction in all-cause mortality, but it can cause significant harms related to false-positive test results, unnecessary biopsies, overdiagnosis, and overtreatment. ⋯ If the prostate-specific antigen level is still elevated, next steps include multiparametric magnetic resonance imaging, assessment of urine or blood biomarkers, and referral to urology. Active surveillance is increasingly accepted as the preferred standard of care for patients with newly diagnosed low-risk prostate cancer, because it is associated with similar long-term survival and better quality of life than curative treatment. The primary intent of screening is to identify patients with clinically significant prostate cancer who may benefit from curative treatment while minimizing the detection of clinically insignificant cancer.
