The European Commission has drafted plans to set an EU-wide minimum tax rate for polluting aviation fuels, as it seeks to meet more ambitious targets to fight climate change, a document seen by Reuters shows.
All viruses, including SARS-CoV-2, the virus that causes COVID-19, change over time. Most changes have little to no impact on the virus’ properties. However, some changes may affect the virus’s properties, such as how easily it spreads, the associated disease severity, or the performance of vaccines, therapeutic medicines, diagnostic tools, or other public health and social measures. WHO, in collaboration with partners, expert networks, national authorities, institutions and researchers have been monitoring and assessing the evolution of SARS-CoV-2 since January 2020. During late 2020, the emergence of variants that posed an increased risk to global public health prompted the characterisation of specific Variants of Interest (VOIs) and Variants of Concern (VOCs), in order to prioritise global monitoring and research, and ultimately to inform the ongoing response to the COVID-19 pandemic. WHO and its international networks of experts are monitoring changes to the virus so that if significant amino acid substitutions are identified, we can inform countries and the public about any changes that may be needed to respond to the variant, and prevent its spread. Globally, systems have been established and are being strengthened to detect “signals” of potential VOIs or VOCs and assess these based on the risk posed to global public health. National authorities may choose to designate other variants of local interest/concern. Reducing transmission through established and proven disease control methods/measures, as well as avoiding introductions into animal populations, are crucial aspects of the global strategy to reduce the occurrence of mutations that have negative public health implications.Current strategies and measures recommended by WHO continue to work against virus variants identified since the start of the pandemic. Evidence from multiple countries with extensive transmission of VOCs has indicated that public health and social measures (PHSM), including infection prevention and control (IPC) measures, have been effective in reducing COVID-19 cases, hospitalizations and deaths. National and local authorities are encouraged to continue strengthening existing PHSM and IPC measures. Authorities are also encouraged to strengthen surveillance and sequencing capacities and apply a systematic approach to provide a representative indication of the extent of transmission of SARS-CoV-2 variants based on the local context, and to detect unusual epidemiological events.
Ist Impfen ein moralisches Gebot? Für die Medizinethikerin Tanja Krones spricht vieles dafür. Doch sie fürchtet: Die unbeabsichtigten Folgen einer Impfpflicht würden die positiven Effekte zunichtemachen.
Gesprochen wird Latein heute kaum mehr, viele Schüler lernen die Sprache trotzdem. Wofür brauchen wir noch Lateinunterricht? Die Antwort gibt uns ausgerechnet ein Feldherr, der vor mehr als zweitausend Jahren gelebt hat.
Die Freiheit des Individuums ist zentral in der liberalen Staatstheorie. Doch ist die Gesellschaft als Ganzes in Gefahr, so wird deren Wohl prioritär. Denn ohne Schutz des Kollektivs können auch die Individualrechte nicht garantiert werden.
