Background Many studies report the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies. We aimed to synthesize data better estimate level and distribution SARS-CoV-2 infection, identify high-risk groups, inform public health decision making. Methods In this systematic review meta-analysis, we searched publication databases, preprint servers, grey literature sources for seroepidemiological study reports, from January 1, 2020 December 31, 2020. included that reported a sample size, date, location, estimate. corrected estimates imperfect test accuracy with Bayesian measurement error models, conducted meta-analysis demographic differences in prevalence antibodies, meta-regression study-level factors associated seroprevalence. compared region-specific confirmed cumulative incidence.

In this study, we analyzed the spread and decay durations of COVID-19 pandemic in several cities China, England, Germany, Japan, where first wave has undergone decay. Differences medical health insurance systems, as well regional policies incommoded comparison different countries. The four studied countries were reordered calculated based on an asymmetric bell-shaped model. We acquired values ambient temperature, absolute humidity, population density to perform multivariable analysis. found a significant correlation (p < 0.05) with Specifically, duration showed high humidity 0.05), whereas demonstrated highest density, maximum temperature 0.05). effect was almost nonexistent China because implemented strict lockdown.

Integrate ecosystem services into socio-economic development to enhance achievement of sustainable development goals in the post-pandemic era

Geography and sustainability, Journal Year: 2021, Volume and Issue: 2(1), P. 68 - 73

Published: March 1, 2021

The COVID-19 pandemic has stalled and rolled back progress on Sustainable Development Goals (SDGs). Ecosystem services (ESs), defined as the contributions of ecosystems to human well-being, underpin achievement SDGs. To promote SDG in post-pandemic era, we teased out links between ESs SDGs while examining impact COVID-19. We found that benefited all SDGs, yet man-made pressures led degradation their services. There is broad consensus virus lurks degraded generates spillover due interference. global lockdown/restriction disrupted flow altered demand, threatening efforts for suggested: 1) study association traceability ESs-SDGs under pandemic; 2) prioritize pressing issues such health care, livelihood, resource security long run, should human-nature harmony achieve SDGs; 3) enhance through local community efforts, accounting, ecosystem restoration. This paper provides insights into importance ways integrate socio-economic development after pandemic.

Protective Face Mask Filter Capable of Inactivating SARS-CoV-2, and Methicillin-Resistant Staphylococcus aureus and Staphylococcus epidermidis

Polymers, Journal Year: 2021, Volume and Issue: 13(2), P. 207 - 207

Published: Jan. 8, 2021

Face masks have globally been accepted to be an effective protective tool prevent bacterial and viral transmission, especially against indoor aerosol transmission. However, commercial face contain filters that are made of materials not capable inactivating either SARS-CoV-2 or multidrug-resistant bacteria. Therefore, symptomatic asymptomatic individuals can infect other people even if they wear them because some viable loads escape from the masks. Furthermore, contact transmission occur after touching mask, which constitutes increasing source contaminated biological waste. Additionally, pathogens contribute SARS-CoV-2-mediated pneumonia disease complex, their resistance antibiotics in treatment is at alarming rate. In this regard, herein, we report development a non-woven mask filter fabricated with biofunctional coating benzalkonium chloride more than 99% particles one minute contact, life-threatening methicillin-resistant Staphylococcus aureus epidermidis (normalized antibacterial halos 0.52 ± 0.04 0.72 0.04, respectively). Nonetheless, despite results obtained, further studies needed ensure safety correct use technology for mass production commercialization broad-spectrum antimicrobial filter.

Published: Oct. 1, 2022

In this Personal View, we explain the ways that climatic risks affect transmission, perception, response, and lived experience of COVID-19. First, temperature, wind, humidity influence transmission COVID-19 in not fully understood, although non-climatic factors appear more important than explaining disease transmission. Second, extremes coinciding with have affected exposure, increased susceptibility people to COVID-19, compromised emergency responses, reduced health system resilience multiple stresses. Third, long-term climate change prepandemic vulnerabilities risk for some populations (eg, marginalised communities). The interact vary considerably between within regions, are by dynamic complex interactions underlying socioeconomic, political, demographic, cultural conditions. These conditions can lead vulnerability, resilience, transformation, or collapse systems, communities, livelihoods throughout varying timescales. It is response recovery measures consider risks, particularly locations susceptible extremes, through integrated planning includes public health, disaster preparedness, management, sustainable development, humanitarian response.
