Vaccine certificate during domestic traveling: a potential initiative to prevent COVID-19 waves in India.
India, the second-most populous country in the world, is struggling with the second wave of the COVID-19 triggered by SARS-CoV-2. This letter aims to highlight the necessity of the vaccine certificate during nationwide traveling to prevent further waves of the COVID-19 in the different states of India. ⋯ The compulsory vaccine certificates need to be in existence to prevent the rapid spread of the COVID-19 as well as the future waves of this pandemic in India. There is an urgent need forStandard Operating Procedure (SOP) on preventive measures to control the spread of COVID-19 nationwide by including the vaccine certificate for domestic travel between the cities and states.

Observational Study
COVID-19 in the California State Prison System: an Observational Study of Decarceration, Ongoing Risks, and Risk Factors.
Correctional institutions nationwide are seeking to mitigate COVID-19-related risks. ⋯ Despite reductions in room occupancy and mixing, California prisons still house many medically vulnerable residents in risky settings. Reducing risks further requires a combination of strategies, including rehousing, decarceration, and vaccination.

[Covid-19 and the animal world, from a still mysterious origin towards an always unpredictable future].
Although the emergence of Covid-19 in China has not been clearly elucidated, the hypothesis of an animal origin remains the most likely. It is supported by the presence of the horseshoe bat suspected to be the progenitor of SARS-CoV-2 and by the scarcity of pork, due to African swine fever, diverting consumers to exotic animals of breeding sold in the markets. During this pandemic, several animal species were affected by SARS-CoV-2. ⋯ The most significant human-to-animal transmission has occurred in mink farms, especially in the Netherlands and Denmark, requiring the euthanasia of several million animals, with mink in turn having contaminated men and stray or nomadic cats. The study of natural or experimental transmissions of SARS-CoV-2 has made it possible to identify the most receptive animal species: American minks and raccoon dogs, and to a lesser extent stray or nomadic cats, which could become an animal reservoir due to their sensitivity to this virus and their extending prolificacy. The European Commission decided on May 17, 2021 to strengthen the surveillance of SARS-CoV-2 infections in minks and other mustelids, as well as in raccoon dogs, highlighting stressing that the epidemiological assessment of the risk presented by the he appearance of SARS-CoV-2 in these susceptible species was a public health priority.

Quantitative SARS-CoV-2 anti-spike responses to Pfizer-BioNTech and Oxford-AstraZeneca vaccines by previous infection status.
We investigated determinants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) anti-spike IgG responses in healthcare workers (HCWs) following one or two doses of Pfizer-BioNTech or Oxford-AstraZeneca vaccines. ⋯ SARS-CoV-2 vaccination leads to detectable anti-spike antibodies in nearly all adult HCWs. Whether differences in response impact vaccine efficacy needs further study.

ReviewBiology of COVID-19 and related viruses: Epidemiology, signs, symptoms, diagnosis, and treatment.
Coronaviruses belong to the family Coronaviridae order Nidovirales and are known causes of respiratory and intestinal disease in various mammalian and avian species. Species of coronaviruses known to infect humans are referred to as human coronaviruses (HCoVs). While traditionally, HCoVs have been a significant cause of the common cold, more recently, emergent viruses, including severe acute respiratory syndrome coronavirus (SARS-CoV-2) has caused a global pandemic. Here, we discuss coronavirus disease (COVID-19) biology, pathology, epidemiology, signs and symptoms, diagnosis, treatment, and recent clinical trials involving promising treatments.
