How to respond effectively to COVID-19? Reports based on environmental changes in Wuhan and Shanghai

Abstract

The δ -variant of COVID-19 is blowing to globle economy, hummen’s life and health. The infection rates of δ -variant is twice of the original variants. It is putting the world in a harsher state. Lockdown policy is still powerful in stopping spread of virus. This paper aims to evaluate the lockdown impact on NO 2 , SO 2 , O 3 , PM 2.5 and PM 10 in Wuhan, which reported the first OVID-19 infection case. We analyzed data of the whole periods including before, during and after blokade. Generally, lockdown has significant decreasing effects on all the 5 pollutants except for surface ozone. The reasons for the pollutants’ changes are discussed from the aspects including social policy, people's living habits and Chinese character. To assess the extensive impact of lockdown policy on urban environment, we also studied the same pollutants in Shanghai, which is one of the biggest and central city in China and almost locates at the same latitude with Wuhan. Better results were obtained compared with those of Wuhan with all the pollutants decreasing their concentration and a better air quality. This effects even last after the blockade. This is mainly because Shanghainese have formed more prudent living habits and attach more importance to environmental protection during the lockdown period. Althgough COVID-19 brings bad effect on globle socio-economy and humen’s health, people get chance to rethink the value of life: We should sustainablely develop and pursuing spiritual instead of excessive material enjoyment. It can sustain a healthy living enviroment.

From pandemic to war: dynamics of volatility spillover between BRICS exchange and stock markets

“…The significant impact of the conflict can be witnessed in the form of increased energy prices, rising defense expenditures, logistic disturbances and a stressed financial system (Alam et al, 2022). In other words, the analogy of the pandemic with the war has not only disturbed the economic stability of the world and the people in general but also influenced human life's social and political aspects (Han and Cong, 2021). However, the magnitude of the impacts will become more evident in the near future as the world is still amidst the crisis.…”

Deuremidevir and Simnotrelvir–Ritonavir for the Treatment of COVID-19

“…It significantly reduced the risk for progression to critical COVID-19 or mortality in the patients. In view of these results, deuremidevir is a promising anti-SARS-CoV-2 agent …”

“…Qian et al mentioned that deuremidevir was approved for the treatment of COVID-19 in Uzbekistan on the basis of the satisfactory results of a clinical study. Junshi Biosciences, as the developer of deuremidevir, announced the result of the clinical trial in an interview . In 2021, a randomized, open-label, controlled phase II clinical trial was performed in patients with moderate and severe COVID-19 in Uzbekistan.…”
