Public Space Accessibility in Vulnerable Areas in Post-Covid Times.

Public space has become a relevant factor for cities since it increases people's quality of life. These areas help reduce physical and mental problems that may arise in society, and in addition, they increase the sense of community and improve the development that children may have. The Covid-19 virus and confinement made this type of space necessary. Although public spaces are taken more into account in the city, they do not take place on the edges of the urban area, as is the case in the community of Paso del Norte in the city of Chihuahua in Mexico. The community has two spaces that can be considered recreation areas, but the reality is that they do not have adequate infrastructure to make them safe and formal places. These make us wonder what the people of this community do in their free time, how they use these public spaces, and how they have evolved over the years. So people in the community were surveyed to solve such unknowns, revealing that these spaces have changed in the last two decades. Especially with the arrival of the Covid-19 pandemic. These green areas added value to the areas where they are, plus many adapted the spaces for recreational, educational, commercial, and productive use. Design is a great tool that can take the detected weaknesses of a community and turn them into strengths to create a good quality public space.

Vaccine effectiveness of ChAdOx1 nCoV-19 against COVID-19 in a socially vulnerable community in Rio de Janeiro, Brazil: a test-negative design study.

OBJECTIVES: To estimate vaccine effectiveness after the first and second dose of ChAdOx1 nCoV-19 against symptomatic COVID-19 and infection in a socially vulnerable community in Brazil when Gamma and Delta were the predominant variants circulating. METHODS: We conducted a test-negative study in the community Complexo da Maré, the largest group of slums (n = 16) in Rio de Janeiro, Brazil, from January 17, 2021 to November 27, 2021. We selected RT-qPCR positive and negative tests from a broad community testing program. The primary outcome was symptomatic COVID-19 (positive RT-qPCR test with at least one symptom) and the secondary outcome was infection (any positive RT-qPCR test). Vaccine effectiveness was estimated as 1 - OR, which was obtained from adjusted logistic regression models. RESULTS: We included 10 077 RT-qPCR tests (6,394, 64% from symptomatic and 3,683, 36% from asymptomatic individuals). The mean age was 40 (SD: 14) years, and the median time between vaccination and RT-qPCR testing among vaccinated was 41 (25-75 percentile: 21-62) days for the first dose and 36 (25-75 percentile: 17-59) days for the second dose. Adjusted vaccine effectiveness against symptomatic COVID-19 was 31.6% (95% CI, 12.0-46.8) 21 days after the first dose and 65.1% (95% CI, 40.9-79.4) 14 days after the second dose. Adjusted vaccine effectiveness against COVID-19 infection was 31.0% (95% CI, 12.7-45.5) 21 days after the first dose and 59.0% (95% CI, 33.1-74.8) 14 days after the second dose. DISCUSSION: ChAdOx1 nCoV-19 was effective in reducing symptomatic COVID-19 in a socially vulnerable community in Brazil when Gamma and Delta were the predominant variants circulating.

COVID-19 restrictions should only be lifted when it is safe to do so for Aboriginal communities.

The NSW Government has proposed a blanket lifting of COVID-19 restrictions when the proportion of fully vaccinated people rate reaches 70% of the adult population. If implemented, this would have devastating effects on Aboriginal populations. At the present time, vaccination rates in Aboriginal communities remain low. Once restrictions are lifted, unvaccinated people will be at high risk of infection. The risks of serious illness and death among Aboriginal people from a variety of medical conditions are significantly greater than for the wider population. This is also the case with COVID-19 in First Nations populations around the world. The vulnerability of Aboriginal people is an enduring consequence of colonialism and is exacerbated by the fact that many live in overcrowded and poorly maintained houses in communities with under-resourced health services. A current workforce crisis and the demographic structure of the population have further hindered the effectiveness of vaccination programmes. Aboriginal organisations have called on state and federal governments to delay any substantial easing of restrictions until full vaccination rates among Aboriginal and Torres Strait Islander populations aged 16 years and older reach 90-95%. They have also called for additional support in the form of supply of vaccines, enhancement of workforce capacity and appropriate incentives to address hesitancy. Australia remains burdened by the legacy of centuries of harm and damage to its First Nations people. Urgent steps must be taken to avoid a renewed assault on Aboriginal and Torres Strait Islander health.
