ReviewHuman Papillomavirus: Screening, Testing, and Prevention.
With more than 200 types identified, human papillomavirus (HPV) commonly causes infections of the skin and mucosa. HPV infection is the most common sexually transmitted infection in the United States. Although most HPV infections are transient and subclinical, some lead to clinical manifestations ranging from benign papillomas or warts to intraepithelial lesions. ⋯ The nonavalent HPV vaccine is effective in preventing the development of high-grade precancerous cervical lesions in noninfected patients. Vaccination is ideally administered at 11 or 12 years of age, irrespective of the patient's sex. In general, a two-dose series is recommended if administered before 15 years of age; however, individuals who are immunocompromised require three doses.

Pertussis, also known as whooping cough, remains a public health concern despite expanded immunization recommendations over the past three decades. The presentation of pertussis, which is variable and evolves over the course of the disease, includes nonspecific symptoms in the catarrhal stage, coughing with the classic whooping in the paroxysmal stage, and persistent cough in the convalescent stage. When there is clinical suspicion for pertussis, the diagnosis should be confirmed using polymerase chain reaction testing, which has replaced culture as the preferred confirmatory test. ⋯ Antibiotic treatment is intended to prevent transmission of pertussis to others and does not shorten the disease course or improve symptoms. Antibiotic prophylaxis is recommended for household contacts of someone with pertussis and for those exposed to pertussis who are at high risk of severe illness (e.g., infants, people who are immunocompromised or in the third trimester of pregnancy) or in close contact with someone at high risk. Azithromycin is the preferred antibiotic for treatment or prophylaxis.
