These findings illustrate that a significant number of women giving birth in Philadelphia test positive for HCV and that most of their at-risk children remain untested. To successfully identify all HCV-infected children and integrate them into HCV-specific care, practices for HCV screening of pregnant women and their children should be improved.
Reports from active drug users state that xylazine, the veterinary tranquilliser, has been increasing in the illicit drug supply in Philadelphia. To describe trends and characteristics of unintentional deaths from heroin and/or fentanyl overdose with xylazine detections occurring in Philadelphia, Pennsylvania, the Philadelphia Department of Public Health analysed data on deaths from unintentional heroin and/or fentanyl overdose from the Philadelphia Medical Examiner’s Office over a 10-year period (2010–2019). Xylazine went from being detected in less than 2% cases of fatal heroin and/or fentanyl overdose between 2010 and 2015 to 262 (31%) of the 858 fatal heroin and/or fentanyl overdose cases in 2019. Currently, information is limited on the presence of xylazine in continental United States. Xylazine’s association with adverse outcomes in other locations indicates that potential health consequences should also be monitored in the USA. Whenever possible, jurisdictions should consistently test for xylazine.

OBJECTIVE One-dose varicella vaccination for children was introduced in the United States in 1995. In 2006, a second dose was recommended to further decrease varicella disease and outbreaks. We describe the impact of the 2-dose vaccination program on varicella incidence, severity, and outbreaks in 2 varicella active surveillance areas. METHODS We examined varicella incidence rates and disease characteristics in Antelope Valley (AV), CA, and West Philadelphia, PA, and varicella outbreak characteristics in AV during 1995–2010. RESULTS In 2010, varicella incidence was 0.3 cases per 1000 population in AV and 0.1 cases per 1000 population in West Philadelphia: 76% and 67% declines, respectively, since 2006 and 98% declines in both sites since 1995; incidence declined in all age groups during 2006–2010. From 2006–2010, 61.7% of case patients in both surveillance areas had been vaccinated with 1 dose of varicella vaccine and 7.5% with 2 doses. Most vaccinated case patients had <50 lesions with no statistically significant differences among 1- and 2-dose cases (62.8% and 70.3%, respectively). Varicella-related hospitalizations during 2006–2010 declined >40% compared with 2002–2005 and >85% compared with 1995–1998. Twelve varicella outbreaks occurred in AV during 2007–2010, compared with 47 during 2003–2006 and 236 during 1995–1998 (P < .01). CONCLUSIONS Varicella incidence, hospitalizations, and outbreaks in 2 active surveillance areas declined substantially during the first 5 years of the 2-dose varicella vaccination program. Declines in incidence across all ages, including infants who are not eligible for varicella vaccination, and adults, in whom vaccination levels are low, provide evidence of the benefit of high levels of immunity in the population.
A hepatitis C virus (HCV)-infected person will ideally have access to quality health care and move through the HCV continuum of care (CoC) from HCV antibody (Ab) screening, HCV-RNA confirmation, engagement and retention in medical care, and treatment. Unfortunately, studies show that many patients do not progress through this continuum. Because these studies may not be generalizable, we assessed the HCV CoC in Philadelphia from January 2010 to December 2013 at the population level. The expected HCV seroprevalence in Philadelphia during 2010-2013 was calculated by applying National Health and Nutrition Examination Survey prevalences to age-specific census data approximations and published estimates of homeless and incarcerated populations. HCV laboratory results reported to the Philadelphia Department of Public Health and enhanced surveillance data were used to determine where individuals fell on the continuum. HCV CoC was defined as follows: stage 1: HCV Ab screening; stage 2: HCV Ab and RNA testing; stage 3: RNA confirmation and continuing care; and stage 4: RNA confirmation, care, and HCV treatment. Of approximately 1,584,848 Philadelphia residents, 47,207 (2.9%) were estimated to have HCV. Positive HCV results were received for 13,596 individuals, of whom 6,383 (47%) had a positive HCV-RNA test. Of these, 1,745 (27%) were in care and 956 (15%) had or were currently receiving treatment. Conclusion: This continuum provides a real-life snapshot of how this disease is being managed in a major U.S. urban center. Many patients are lost at each stage, highlighting the need to raise awareness among health care professionals and at-risk populations about appropriate hepatitis testing, referral, support, and care. (HEPATOLOGY 2015;61:783-789) H epatitis C virus (HCV) is the primary cause of chronic hepatitis disease in the United States, infecting approximately 3.2 million people.1,2 A major challenge in the management of HCV is its silent progression from acute to chronic disease. Because acute infection is asymptomatic in 60%-70% of individuals, many only learn that they are HCV positive decades later, after their disease has progressed to cirrhosis, hepatocellular carcinoma (HCC), or liver failure.3-5 Thus, diagnosis relies heavily on HCV screening of at-risk individuals, including injection drug users, recipients of blood transfusions, solid-organ transplants before 1992 or clotting-factor concentrates made before 1987, patients who ever received long-term hemodialysis; human immunodeficiency virus (HIV)-infected persons, persons with known HCV exposures, children born to chronically infected mothers, and, most recently, adults born during 1945-1965. 3,4 Unfortunately, there are still several barriers to successful testing in health care settings. [6][7][8] Even when patients are successfully screened, many do not receive confirmatory nucleic acid testing (NAT) for HCV RNA.9 Without NAT results, physicians cannot effectively differentiate between the 15%-25% of people who have resolved infection after exposure...
