Objective The purpose of this study was to determine if the COVID-19 pandemic had differential effects on individuals with chemical intolerances (CI). CI is characterised by multisystem symptoms initiated a one-time high dose or persistent low-dose exposure environmental toxins including chemicals, foods and drugs. With an estimated 20% US prevalence, include fatigue, headache, weakness, rash, mood changes, musculoskeletal pain, gastrointestinal issues, difficulties memory, concentration respiratory problems, which are similar its sequelae. Design A population-based survey involving 7500 respondents asked they ever COVID-19, what severity was, long COVID-19. assessed using Quick Environmental Exposure Sensitivity Inventory. Setting Center for Disease Control estimates that over 24 million have been infected in USA 6 700 000 being hospitalised 1 174 deaths. Other industrialised countries show numbers. Results Those High class reported greater symptom than medium low groups (p<0.0001). These associations were independent race, ethnicity, income, age sex. However, there significantly increased odds among women those 45 years old. Asian least likely severe compared white (OR=0.53; 95% 0.35 0.79). Black/African American lower prevalence non-Hispanic whites. one interaction between race significant, African Americans (OR=2.2; 1.15 3.16) reporting prevalence. Furthermore, severity. Conclusion Prior studies higher risk older groups, male sex, pre-existing comorbidities (eg, challenged immunities) from minoritised racial/ethnic groups. results suggest be included high-risk group. Various subsets may exist future investigations could identify different subsets. Understanding these subgroups would helpful mounting targeted prevention efforts.

Opportunities Arising from COVID-19 Risk Management to Improve Ultrafine Particles Exposure: Case Study in a University Setting

Sustainability, Journal Year: 2025, Volume and Issue: 17(11), P. 4803 - 4803

Published: May 23, 2025

Particulate matter (PM) is recognized as a leading health risk factor worldwide, causing adverse effects for people in living and working environments. During the COVID-19 pandemic, it was shown that ultrafine particles (UFP) PM concentrations, may have played an important role transmission of SARS-CoV-2. This study aims to investigate whether mechanical ventilation system installed mitigation measure university dining hall can be effectively sustainably used improve indoor UFP exposure levels, integrated with continuous low-cost sensor monitoring system. Measurements particle number concentration (PNC), average diameter (Davg), Lung Deposited Surface Area (LDSA) were performed over three days divided into ten homogeneous daily time slots (from 12:00 am 11:59 pm) using high-frequency (1 Hz) real-time devices. other pollutants (CO2 TVOC) monitored handheld sensors. Indoor PNC (Dp < 700 nm) increased showed great variability related activities, reaching maximum level 30,000 part/cm3 (st. dev. 16,900). Davg 300 during lunch dinner times, from 22 nm at night 48 post-dinner recovery activities. Plasma-based filter technology reduced by up mitigating concentrations environments, especially access periods. It could successfully adopted also after pandemic emergency, sustainable safety control UFPs levels.

CO2 Concentration Assessment for Infection Monitoring and Occupancy Analysis in Tanzanian COVID-19 Isolation Centers

Buildings, Journal Year: 2024, Volume and Issue: 14(7), P. 2139 - 2139

Published: July 11, 2024

Monitoring of IAQ is one the foundations preventative actions prompted by worldwide recognition COVID-19 transmission. The measurement CO2 has emerged as most popular, dependable, and easy ways to indirectly evaluate state indoor air renewal. Reducing risk respiratory diseases transmitted aerosols attainable through implementing validating prevention measures made possible control. Isolation centers are like health facilities in that they linked IAQ, presence natural ventilation can significantly improve circulation fresh air, which speeds up removal contaminants. This true even though healthcare among environments with highest rate propagation. Our investigation revealed, however, no substantial critical data on quality Tanzanian isolation presently available. process metabolic CO₂ creation accumulation within center cubicles was investigated this study. Crucially, we suggest comparing settings under various conditions using indicator ppm/patient. In research, experimentally assessed value changing a few HVAC system characteristics. We looked at see how well filtration worked concerning submicron particle concentration. Study recommendations for detectors reduce infection shared provided. also show correlation between size concentration, concentration derivatives volume presented per patient cubicles, occupancy levels adjusting patient’s bed position. study found exposure lengths two three hours, typical hospital cubicle fifty hundred people should have an average interior less than 900 ppm. Carers’ length stay substantially impacted permissible By establishing connection monitoring goals, will aid determining feasibility regulations content depending settings, strengthening preventive efforts against COVID-19. post-pandemic era, it be essential find make cleaner so infectious cannot spread future.

Effects of the COVID-19 pandemic on individuals with Chemical Intolerance

medRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Published: May 24, 2024

Abstract Background The Center for Disease Control has estimated that over 24 million have been infected with COVID-19 in the US 6,700,000 being hospitalized, and 1,174,000 deaths. Several other industrialized countries show similar numbers (CSSE, 2021). Chemical Intolerance (CI) is characterized by multi-system symptoms initiated a one-time high dose or persistent low-dose exposure to environmental toxins including chemicals, foods drugs. With an 20% prevalence US, of CI include fatigue, headache, weakness, rash, mood changes, musculoskeletal pain, gastrointestinal issues, difficulties memory, concentration, respiratory problems which are its sequelae. purpose this study was determine if pandemic had differential effects on those individuals CI. Methods A large U.S. population-based survey launched involving 7,500 respondents asking they ever COVID-19, what severity it was, long COVID-19. Respondents were also assessed using Quick Environmental Exposure Sensitivity Inventory (QEESI), 50-item validated questionnaire designed assess intolerances inhaled foods, and/or classified as Low, Medium, High Results Those class reported greater prevalence, symptom severity, then Medium Low classes (P<.0001). These associations independent race, ethnicity, income, age, gender. However, there significantly increased odds among females 45 years old. Asian least likely severe compared White (OR = 0.60). Black/African American lower than Non-Hispanic Whites (NHW), but African 2.2 reporting prevalence. Further, severity. Discussion Prior studies showed higher risk COVID-19-19 infection elderly, male sex, pre-existing comorbidities (e.g., challenged immunities) from minoritized racial/ethnic groups. results suggest be included group. Various subsets may exisit future investigations could identify different subsets. Understanding these subgroups would helpful mounting targeted prevention efforts.

Concrete Actions for Improving Indoor Air Quality in Korea: Advancing Public Health for Vulnerable Populations

Atmosphere, Journal Year: 2024, Volume and Issue: 15(11), P. 1389 - 1389

Published: Nov. 18, 2024

In modern society, individuals spend an increasing amount of time indoors, emphasizing the importance understanding health impacts indoor environments. This study focused on measuring air quality to identify vulnerable populations and observe effects residential environment improvements quality. Targeting low-income families elderly households, known for their heightened vulnerability environmental risks, involved direct visits 2328 households across 16 cities provinces in South Korea from 2021 2022. Indoor parameters, including PM2.5, PM10, total volatile organic compounds (TVOC), formaldehyde (HCHO), airborne mold, were measured. Among these 300 with critically compromised living conditions received support wallpaper paneling replacement. Comparative measurements before after renovations revealed that single-person had higher levels PM2.5 TVOC compared four or more members. Additionally, elevated concentrations mold also exhibited PM10. Importantly, showed a significant reduction concentration by approximately 50% more. underscores provides valuable evidence supporting policies promotion welfare populations. The research is distinguished its comprehensive nature, involving nearly 2000 nationwide, rather than relying solely secondary data.
