COVID-19 Case Surveillance: Trends in Person-Level Case Data Completeness, United States, April 5-September 30, 2020.

Objectives: To obtain timely and detailed data on COVID-19 cases in the United States, the Centers for Disease Control and Prevention (CDC) uses 2 data sources: (1) aggregate counts for daily situational awareness and (2) person-level data for each case (case surveillance). The objective of this study was to describe the sensitivity of case ascertainment and the completeness of person-level data received by CDC through national COVID-19 case surveillance.

Methods: We compared case and death counts from case surveillance data with aggregate counts received by CDC during April 5-September 30, 2020.

Race, Ethnicity, and Age Trends in Persons Who Died from COVID-19 - United States, May-August 2020.

During February 12-October 15, 2020, the coronavirus disease 2019 (COVID-19) pandemic resulted in approximately 7,900,000 aggregated reported cases and approximately 216,000 deaths in the United States.* Among COVID-19-associated deaths reported to national case surveillance during February 12-May 18, persons aged ≥65 years and members of racial and ethnic minority groups were disproportionately represented (1). This report describes demographic and geographic trends in COVID-19-associated deaths reported to the National Vital Statistics System (NVSS) during May 1-August 31, 2020, by 50 states and the District of Columbia.

Cesarean delivery for HIV-infected women: recommendations and controversies.

Two studies that were published in 1999 demonstrated that cesarean delivery before labor and before the rupture of membranes (elective cesarean delivery) reduces the risk of mother-to-child transmission of the human immunodeficiency virus (HIV). On the basis of these results, the American College of Obstetricians and Gynecologists and the US Public Health Service recommend that HIV-infected pregnant women with plasma viral loads of >1000 copies per milliliter be counseled regarding the benefits of elective cesarean delivery. Since the release of these guidelines, the cesarean delivery rate among HIV-infected women in the United States has increased dramatically.

Sex workers in Vietnam: how many, how risky?

Because of concerns for HIV risks and need to plan effective programs, we assessed the number and risks of sex workers in Nha Trang City, Vietnam. Sex workers were contacted in streets, beaches, bars, and restaurants, and a capture-recapture method was used to estimate their number. An estimated 444 women worked on the streets and beach ("direct" sex workers) and 486 worked in bars and restaurants or other facilities ("indirect" sex workers).

SARS surveillance during emergency public health response, United States, March-July 2003.

In response to the emergence of severe acute respiratory syndrome (SARS), the United States established national surveillance using a sensitive case definition incorporating clinical, epidemiologic, and laboratory criteria. Of 1,460 unexplained respiratory illnesses reported by state and local health departments to the Centers for Disease Control and Prevention from March 17 to July 30, 2003, a total of 398 (27%) met clinical and epidemiologic SARS case criteria. Of these, 72 (18%) were probable cases with radiographic evidence of pneumonia.
