Seroprevalence of Severe Acute Respiratory Syndrome Coronavirus 2 Following the Largest Initial Epidemic Wave in the United States: Findings From New York City, 13 May to 21 July 2020.

BACKGROUND: New York City (NYC) was the US epicenter of the spring 2020 coronavirus disease 2019 (COVID-19) pandemic. We present the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and correlates of seropositivity immediately after the first wave. METHODS: From a serosurvey of adult NYC residents (13 May to 21 July 2020), we calculated the prevalence of SARS-CoV-2 antibodies stratified by participant demographics, symptom history, health status, and employment industry. We used multivariable regression models to assess associations between participant characteristics and seropositivity. RESULTS: The seroprevalence among 45 367 participants was 23.6% (95% confidence interval, 23.2%-24.0%). High seroprevalence (>30%) was observed among black and Hispanic individuals, people from high poverty neighborhoods, and people in healthcare or essential worker industry sectors. COVID-19 symptom history was associated with seropositivity (adjusted relative risk, 2.76; 95% confidence interval, 2.65-2.88). Other risk factors included sex, age, race/ethnicity, residential area, employment sector, working outside the home, contact with a COVID-19 case, obesity, and increasing numbers of household members. CONCLUSIONS: Based on a large serosurvey in a single US jurisdiction, we estimate that just under one-quarter of NYC adults were infected in the first few months of the COVID-19 epidemic. Given disparities in infection risk, effective interventions for at-risk groups are needed during ongoing transmission.

Demographic considerations in analyzing decedents by usual occupation.

BACKGROUND: Public health research uses decedents' usual industry and occupation (I&O) from US death certificates to assess mortality incidence and risk factors. Of necessity, such research may exclude decedents with insufficient I&O information, and assume death certificates reflect current (at time of death) I&O. This study explored the demographic implications of such research conditions by describing usual occupation and current employment status among decedents by demographic characteristics in a large multistate data set. METHODS: Death certificate occupations classified by Standard Occupational Classification (SOC) (ie, compensated occupation) and other categories (eg, student) for 36 507 decedents (suicide, homicide, other, undetermined intent) age 22+ years from the 2016 National Violent Death Reporting System's (NVDRS) 32 US states were analyzed. Decedents not employed at the time of death (eg, laid off) were identified through nondeath certificate NVDRS data sources (eg, law enforcement reports). RESULTS: Female decedents, younger (age < 30 years) male decedents, some non-White racial group decedents, less educated decedents, and undetermined intent death decedents were statistically less likely to be classified by SOC based on death certificates-primarily due to insufficient information. Decedents classified by SOC from death certificates but whose non-death certificate data indicated no employment at the time of death were more often 30+ years old, White, less educated, died by suicide, or had nonmanagement occupations. CONCLUSIONS: Whether decedents have classifiable occupations from death certificates may vary by demographic characteristics. Research studies that assess decedents by usual I&O can identify and describe how any such demographic trends may affect research results on particular public health topics.

Suicide Rates by Industry and Occupation - National Violent Death Reporting System, 32 States, 2016.

In 2017, nearly 38,000 persons of working age (16-64 years) in the United States died by suicide, which represents a 40% rate increase (12.9 per 100,000 population in 2000 to 18.0 in 2017) in less than 2 decades.* To inform suicide prevention, CDC analyzed suicide data by industry and occupation among working-age decedents presumed to be employed at the time of death from the 32 states participating in the 2016 National Violent Death Reporting System (NVDRS).†,§ Compared with rates in the total study population, suicide rates were significantly higher in five major industry groups: 1) Mining, Quarrying, and Oil and Gas Extraction (males); 2) Construction (males); 3) Other Services (e.g., automotive repair) (males); 4) Agriculture, Forestry, Fishing, and Hunting (males); and 5) Transportation and Warehousing (males and females). Rates were also significantly higher in six major occupational groups: 1) Construction and Extraction (males and females); 2) Installation, Maintenance, and Repair (males); 3) Arts, Design, Entertainment, Sports, and Media (males); 4) Transportation and Material Moving (males and females); 5) Protective Service (females); and 6) Healthcare Support (females). Rates for detailed occupational groups (e.g., Electricians or Carpenters within the Construction and Extraction major group) are presented and provide insight into the differences in suicide rates within major occupational groups.

Suicide Rates by Major Occupational Group - 17 States, 2012 and 2015.

During 2000-2016, the suicide rate among the U.S. working age population (persons aged 16-64 years) increased 34%, from 12.9 per 100,000 population to 17.3 (https://www.cdc.gov/injury/wisqars). To better understand suicide among different occupational groups and inform suicide prevention efforts, CDC analyzed suicide deaths by Standard Occupational Classification (SOC) major groups for decedents aged 16-64 years from the 17 states participating in both the 2012 and 2015 National Violent Death Reporting System (NVDRS) (https://www.cdc.gov/violenceprevention/nvdrs). The occupational group with the highest male suicide rate in 2012 and 2015 was Construction and Extraction (43.6 and 53.2 per 100,000 civilian noninstitutionalized working persons, respectively), whereas the group with the highest female suicide rate was Arts, Design, Entertainment, Sports, and Media (11.7 [2012] and 15.6 [2015]). The largest suicide rate increase among males from 2012 to 2015 (47%) occurred in the Arts, Design, Entertainment, Sports, and Media occupational group (26.9 to 39.7) and among females, in the Food Preparation and Serving Related group, from 6.1 to 9.4 (54%).

Tdap Vaccination Among Healthcare Personnel-21 States, 2013.

INTRODUCTION: Outbreaks of pertussis can occur in healthcare settings. Vaccinating healthcare personnel may be helpful in protecting healthcare personnel from pertussis and potentially limiting spread to others in healthcare settings. METHODS: Data from 21 states using the 2013 Behavioral Risk Factor Surveillance System industry/occupation module were analyzed in 2016. Tetanus, diphtheria, and acellular pertussis (Tdap) vaccination status was self-reported by healthcare personnel along with their occupation, healthcare setting/industry, demographics, and access to care factors. To compare groups, t-tests were used. The median state response rate was 44.0%. RESULTS: Among all healthcare personnel, 47.2% were vaccinated for Tdap. Physicians had higher Tdap coverage (66.8%) compared with all other healthcare personnel except nurse practitioners and registered nurses (59.5%), whose coverage did not statistically differ from that of physicians. Tdap vaccination coverage was higher among workers in hospitals (53.3%) than in long-term care facilities (33.3%) and other clinical settings, such as dentist, chiropractor, and optometrist offices (39.3%). Healthcare personnel who were younger, who had higher education, higher annual household income, a personal healthcare provider, and health insurance had higher Tdap vaccination coverage compared with reference groups. Tdap vaccination coverage among healthcare personnel in 21 states ranged from 30.6% in Mississippi to 65.9% in Washington. CONCLUSIONS: Improvement in Tdap vaccination among healthcare personnel is needed to potentially reduce opportunities for spread of pertussis in healthcare settings. On-site workplace vaccination, offering vaccines free of charge, and promoting vaccination may increase vaccination among healthcare personnel.

Improving the quality of industry and occupation data at a central cancer registry.

BACKGROUND: Central cancer registries are required to collect industry and occupation (I/O) information when available, but the data reported are often incomplete. METHODS: We audited the completeness of I/O data in the New Hampshire State Cancer Registry (NHSCR) database for diagnosis year 2005, and reviewed medical records for a convenience sample of 474 of these cases. We compared I/O data quality before and after a statewide registrar training session on occupationally related cancers. RESULTS: The original 2005 data contained both I/O data in 11.5% of cases, and lacked any I/O data in 74.5%. Corresponding figures for cases selected for audit were 15.2% and 77.2%, which improved to 54.2% and 11.8% after medical record review. After registrar training, 47% of reports contained both I/O data, and only 14.4% of cases lacked any I/O data. CONCLUSIONS: Statewide training to highlight the importance of I/O data is an effective method to improve I/O data quality.
