The Minister of Health, Carolina Darias, today announced that face masks will no longer be compulsory indoors after Easter. The measure will come into force on 20 April. It will continue to be compulsory in public transport, health centres and residences, but the final details of the new scenario are not yet known.
A study assesses the health impacts of the 2020 closures in three European cities that implemented different measures: Barcelona, Stockholm and Vienna. The researchers took data on changes in pollution, noise and physical activity at three different points in time. Their findings suggest that, while the reduction in noise and pollution may have been positive for health, the negative consequences of the lack of physical activity were generally greater.
The Public Health Commission has updated the Covid-19 Surveillance and Control Strategy, which will come into force on Monday 28 March. From then on, as long as indicators of healthcare utilisation are at low risk, diagnostic testing will focus on vulnerable individuals and settings and severe cases. Surveillance will focus on these groups.
The WHO recommends keeping an eye on the BA.2 variant of Omicron because it is spreading, but it does not appear to cause more serious disease or escape vaccination. Don't be fooled by its evocative nickname: it is perfectly detectable. The misconception that tests do not identify it was propagated by a headline that was corrected.
The terms "endemism" and "seasonality" are increasingly used to refer to the covid-19 pandemic. They are sometimes incorrectly associated with the severity of the disease or with the premature end of the pandemic. What do they mean? Does SARS-CoV-2 fit these definitions? Will it ever do so thanks to vaccines?
The first solid work on the ability of vaccines to stop infection with the omicron variant, which has just been published, reinforces the need for a third dose. Experts recall, however, that the aim of vaccines was never to stop infection, but to prevent severe disease. We summarize what is known so far about it.
"Equity in the distribution of vaccines is not a matter of charity; it benefits all countries," said Tedros Adhanom, director of the WHO. However, his data speak of a very unequal distribution: more than 80 % of the vaccines have gone to G20 countries, while poor countries, mostly African, have received only 0.6 %. Three Spanish experts analyze what went wrong.
The discovery of the Omicron variant has led to the cancellation of flights to several African countries, while many countries are beginning to detect cases among travellers from countries such as South Africa, but also Nigeria and Egypt. Spain has just announced the first detected case of Omicron, which corresponds to a traveller who had visited South Africa. What measures should be taken to stop the spread of this variant? Is it even possible?
The message that we must continue to protect ourselves with masks, distance, ventilation and hand washing has been repeated since the beginning of vaccination, but in the midst of the pandemic in Europe it is even more important. Several experts warn that the high vaccination coverage in Spain will mitigate the new wave but will not eliminate it: although vaccines prevent serious disease, they are not an insurmountable shield and must be complemented with behavioral measures.
European countries are implementing anti-covid strategies in the unvaccinated population. Austria will make vaccination mandatory after extending its confinement targeting the unvaccinated to the entire population. In Germany, the unimmunized have restricted access to restaurants and hotels, and must show a negative test on public transport. Slovakia has also imposed restrictions on those who have chosen not to be vaccinated. Sweden will introduce a covid passport at events of more than 100 people. What is the effect of these policies?
