Koroaldaerekin ez galtzeko gida arina
Dibulgazio-oporretan banago ere, eta pandemiari buruz aritzetik distantzia pixka bat hartu nahi banuen ere, egoera zein den ikusita, ba zerbait arina kozinatzea otu zait. Baina ez aditu moduan (horrek dakartzan lanekin), baizik eta kafepintxo baten inguruan lagun bat

Airborne transmission by droplets and aerosols is important for the spread of viruses. Face masks are a well-established preventive measure, but their effectiveness for mitigating SARS-CoV-2 transmission is still under debate. We show that variations in mask efficacy can be explained by different regimes of virus abundance and related to population-average infection probability and reproduction number. For SARS-CoV-2, the viral load of infectious individuals can vary by orders of magnitude. We find that most environments and contacts are under conditions of low virus abundance (virus-limited) where surgical masks are effective at preventing virus spread. More advanced masks and other protective equipment are required in potentially virus-rich indoor environments including medical centers and hospitals. Masks are particularly effective in combination with other preventive measures like ventilation and distancing.
Intzidentziarik gabeko udalerria dugu egun Usurbil. Azken bi asteotan ez da covid19 kasu berririk izan. Eremu berdean gara duela 7 egunetik. Eta testuinguru honetan, 100.000 biztanleko 14 eguneko 0,0ko intzidentzia izatera heldu gara udalerri honetan. Bai Buruntzaldeko eta Gipuzkoa osoko 5.000 biztanletik gorako udalerrien artean tasa baxuena duen udalerria dugu egun. Bestela esanda, eremu berdean segitzen duen Usurbilek covid19ari lotutako intzidentziarik gabeko egoerara igaro da. Halere orain, egoera honi eusteko inoiz baino zorrotzago betetzen segi beharko dira ezarrita dauden prebentzio neurriak.
Ikertzaile berdinek antzeko emaitzak lortu zituzten Dublingo autobus batean egindako probetan ere.

Tranbia eta autobusen metalezko egiturek Bluetooth uhinak islatzen dituzte eta pertsonek absorbatu. Ondorioz, seinalearen indarraren eta distantziaren arteko korrelazioa ahula da.
Garraio publikoa #koronabirusaren zabalkundea detektatzeko aplikazioak erabilgarriak izan daitezkeen ingurune bat da, baina ikerketa hauetatik emaitzak oso kaskarrak direla ondorioztatzen da.
We report on the results of a Covid-19 contact tracing app measurement study carried out on a standard design of European commuter tram. Our measurements indicate that in the tram there is little correlation between Bluetooth received signal strength and distance between handsets. We applied the detection rules used by the Italian, Swiss and German apps to our measurement data and also characterised the impact on performance of changes in the parameters used in these detection rules. We find that the Swiss and German detection rules trigger no exposure notifications on our data, while the Italian detection rule generates a true positive rate of 50% and a false positive rate of 50%. Our analysis indicates that the performance of such detection rules is similar to that of triggering notifications by randomly selecting from the participants in our experiments, regardless of proximity.
