How flu is spread

Pubblicato il 13/02/2013Read time: 1 min

Avoiding close contacts with infected people could not be enough as a defense against flu. This is the conclusion of a recent study by scientists at the Wake Forest School of Medicine, published on the Journal of Infectious Diseases. The swab specimens of 94 subjects, admitted to the hospital with influenza-like illness, have been analyzed and their medical history recorded, revealing that 61 of them were actually positive for flu. Researchers then collected air samples from each patient, looking for infectious particles. This allowed to discover that 26 of them released virus particles into the air, with 5 being highly infectious, emitting up to 32 times more virus than others. Patients who reported severe illness and major interference with daily life also emitted more influenza virus.
These results thus seem to question the conventional wisdom that flu is mainly spread through close contact with others and by touching contaminated surfaces.

Approved the law for the restoration of European nature, but it's a half victory

On November 9, the European Council approved the Nature Restoration Law, a regulation for the restoration of ecosystems. A much-hoped-for victory that leaves a bitter taste: the adopted regulation emerges from more than a year of negotiations that have significantly weakened it in substance. The risk is that the objectives lose their concreteness in implementation.

On November 9, the European Council, the body defining the EU's policy directions, approved the Nature Restoration Law, one of the four main pillars of the European biodiversity strategy for 2030. A great achievement, yet leaving a bit of bitterness, considering the approved regulation was significantly weakened compared to the original.
