(.50 RC) - As of April 16, 2021, U.S. correctional and detention facilities reported 399,631 cases of COVID-19 in incarcerated persons, resulting in 2,574 deaths (1). During July 14–November 30, 2020, COVID-19 was diagnosed in 382 persons incarcerated in Idaho correctional facilities with work-release programs. Work-release programs (which place incarcerated persons in community businesses) have social and economic benefits, but might put participants at increased risk for bidirectional transmission of SARS-CoV-2, the virus that causes COVID-19… (CDC MMWR, Apr 23 2021)

READ: Research suggests aircraft seating related to SARS-CoV-2 exposure

(.50 RC) - Aircraft can hold large numbers of persons in close proximity for long periods, which can increase the risk for transmission of infectious disease. Current CDC guidelines recommend against travel for persons who have not been vaccinated against COVID-19, and a January 2021 CDC order requires masking for all persons while on airplanes. Research suggests that seating proximity on aircraft is associated with increased risk for infection with SARS-CoV-2… (CDC MMWR, Apr 23 2021)

(3 RC) - Observations show that warming of the climate is unequivocal. The global warming observed over the past 50 years is due primarily to human-induced emissions of heat-trapping gases. These emissions come mainly from the burning of fossil fuels (coal, oil, and gas), with important contributions from the clearing of forests, agricultural practices, and other activities… (EPA)

(4 RC) - Environmental factors play a large role in children’s health. According to the World Health Organization, more than 30% of the global burden of disease in children is due to environmental factors. Children’s growth and development are dynamic processes; they can be viewed at the molecular, cellular, organ, and whole-child levels. What determines the nature and severity of environmental factors’ health effects is exposure occurrence within the different developmental stages… (ATSDR, Feb 2012)

(1 RC) - The draft proposed sampling plan provides an overview of how buildings (residential, office, and public) south of Houston Street, in Manhattan, would be sampled to determine if any remaining WTC-related contamination is present. As proposed, only dust samples would be taken from buildings made available by the owners or managers. Samples would be taken from locations where exposures are likely to occur, such as in elevated horizontal surfaces.… (ATSDR, Mar 2005)
