VIVO EL PRESENTE



lista de paises que obliguen a sus ciudadanos a ponerse el bozal hasta para ir a plantar un pino como en españa



esto es una medida POLITICA mas que SANITARIA
Quien vive el presente y no se prepara para el futuro acaba dandose la ostia... o vive empufao hasta las trancas (cosa bastante tipica en este pais, por cierto)... o ambas.

diselo al psoe y podemos
Se lo diria, pero no me harian puto caso. Si eres de los que cree que simpatizo com el gobierno (hay unos cuantos por aqui) te equivocas. Estoy de acuerdo en que son una panda. Pero eso no cambia que las mascarillas son necesarias, tanto cuando el gobierno decia que no, como ahora.

Pues lo de las mascarillas al aire libre es de cajon incluso para profanos, ahora bien la asistencia médica a distancia es algo con mucho futuro, no valdrá para todos ni para todo y tendrá que mejorar mucho, pero será de gran utilidad, yo apostaria por su implantación, en unos paises de puta madre y en otros de puta pena pero con posibilidades constantes de mejora. Tambien entiendo que esto suene a ia y a muchos medicos no le haga gracia.

Estoy esperando las legiones de enfermos por usar mascarilla... esta todo colapasado... jajajajajajajajaja
Llevo una dermatitis atópica en la barbilla por llevar la mascarilla desde la imposición por la calle por descubrirme el rostro para respirar bien. Mi mujer con pequeñas rojeces en el cuello desde que lleva mascarilla, no solo para trabajar, trabaja en un centro médico privado si no por llevarla en la calle.

Su jefa se trata varias rojeces del cierre de la mascarilla con corticoide. Se le va a poner la cara chula.

Y esto es lo flojillo, fruto de la retención bacteriana In-frasier, lo bueno va a llegar a medio plazo.

Son necesarias en España, resto de Europa no evidentemente que listos somos.

Transmission of SARS-CoV-2

Note: A COVID-19 (SARS-CoV-2) particle is 0.125 micrometers (μm); influenza virus size is 0.08 – 0.12 μm; a human hair is about 150 μm.
*1 nm = 0.001 micron; 1000 nm = 1 micron; Micrometer (μm) is the preferred name for micron (an older term)
1 meter is = 1,000,000,000 nm or 1,000,000 microns
Droplets
Air currents
  • In air conditioned environment these large droplets may travel farther.​
  • However, ventilation — even the opening of an entrance door and a small window can dilute the number of small droplets to one half after 30 seconds. (This study looked at droplets from uninfected persons). This is clinically relevant because poorly ventilated and populated spaces, like public transport and nursing homes, have high SARS-CoV-2 disease transmission despite physical distancing. https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(20)30245-9/fulltext





Objects and surfaces
  • Person to person touching​
  • The CDC’s most recent statement regarding contracting COVID-19 from touching surfaces: “Based on data from lab studies on Covid-19 and what we know about similar respiratory diseases, it may be possible that a person can get Covid-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose or possibly their eyes,” the agency wrote. “But this isn’t thought to be the main way the virus spreads. Coronavirus Disease 2019.​
  • Chinese study with data taken from swabs on surfaces around the hospital
    Aerosol and Surface Distribution of Severe Acute Respiratory Syndrome Coronavirus 2 in Hospital Wards, Wuhan, China, 2020
    • The surfaces where tested with the PCR (polymerase chain reaction) test, which greatly amplifies the viral genetic material if it is present. That material is detectable when a person is actively infected. This is thought to be the most reliable test.
      • Computer mouse (ICU 6/8, 75%; General ward (GW) 1/5, 20%)​
      • Trash cans (ICU 3/5, 60%; GW 0/8)​
      • Sickbed handrails (ICU 6/14, 42.9%; GW 0/12)​
      • Doorknobs (GW 1/12, 8.3%)​
      • 81.3% of the miscellaneous personal items were positive:
        • Exercise equipment​
        • Medical equipment (spirometer, pulse oximeter, nasal cannula)​
        • PC and iPads​
        • Reading glasses​
        • Cellular phones (83.3% positive for viral RNA)​
        • Remote controls for in-room TVs (64.7% percent positive)​
        • Toilets (81.0% positive)​
        • Room surfaces (80.4% of all sampled)​
        • Bedside tables and bed rails (75.0%)​
        • Window ledges (81.8%)​
        • Plastic: up to 2-3 days​
        • Stainless Steel: up to 2-3 days​
        • Cardboard: up to 1 day​
        • Copper: up to 4 hours​
        • Floor – gravity causes droplets to fall to the floor. Half of ICU workers all had virus on the bottoms of their shoes​
Filter Efficiency and Fit
*Data from a University of Illinois at Chicago review
COMMENTARY: Masks-for-all for COVID-19 not based on sound data
  • HEPA (high efficiency particulate air) filters – 99.97 – 100% efficient. HEPA filters are tested with particles that are 0.125 μm.​
  • Masks and respirators work by collecting particles through several physical mechanisms, including diffusion (small particles) and interception and impaction (large particles)​
  • N95 filtering facepiece respirators (FFRs) are constructed from electret (a dielectric material that has a quasi-permanent electric charge. An electret generates internal and external electric fields so the filter material has electrostatic attraction for additional collection of all particle sizes. As flow increases, particles will be collected less efficiently.​
  • N95 – A properly fitted N95 will block 95% of tiny air particles down to 0.3 μm from reaching the wearer’s face. N95 Masks Explained | Honeywell.
    • But even these have problems: many have exhalation valve for easier breathing and less moisture inside the mask.​
    • Surgical masks are designed to protect patients from a surgeon’s respiratory droplets, aren’t effective at blocking particles smaller than 100 μm. Respirators and Surgical Masks: A Comparison
    • Filter efficiency was measured across a wide range of small particle sizes (0.02 to 1 µm) at 33 and 99 L/min.
      • N95 respirators had efficiencies greater than 95% (as expected).​
      • T-shirts had 10% efficiency,​
      • Scarves 10% to 20%,​
      • Cloth masks 10% to 30%,​
      • Sweatshirts 20% to 40%, and​
      • Towels 40%.​
      • All of the cloth masks and materials had near zero efficiency at 0.3 µm, a particle size that easily penetrates into the lungs.​
      • Another study evaluated 44 masks, respirators, and other materials with similar methods and small aerosols (0.08 and 0.22 µm).
        • N95 FFR filter efficiency was greater than 95%.​
        • Medical masks – 55% efficiency​
        • General masks – 38% and​
        • Handkerchiefs – 2% (one layer) to 13% (four layers) efficiency.​
      • Conclusion: Wearing masks will not reduce SARS-CoV-2.
        • N95 masks protect health care workers, but are not recommended for source control transmission.​
        • Surgical masks are better than cloth but not very efficient at preventing emissions from infected patients.​
        • Cloth masks will be ineffective at preventing SARS-CoV-2 transmission, whether worn as source control or as personal protective equipment (PPE).​
“Masks may confuse that message and give people a false sense of security. If masks had been the solution in Asia, shouldn’t they have stopped the pandemic before it spread elsewhere?”
*The first randomized controlled trial of cloth masks. A cluster randomised trial of cloth masks compared with medical masks in healthcare workers | BMJ Open
  • Penetration of cloth masks by particles was 97% and medical masks 44%, 3M Vflex 9105 N95 (0.1%), 3M 9320 N95 (<0.01%).
    • Moisture retention, reuse of cloth masks and poor filtration may result in increased risk of infection.​
    • The virus may survive on the surface of the face- masks​
    • Self-contamination through repeated use and improper doffing is possible. A contaminated cloth mask may transfer pathogen from the mask to the bare hands of the wearer.​
    • Cloth masks should not be recommended for health care workers, particularly in high-risk situations, and guidelines need to be updated.​

En Corea se las puso to dios y ningun pais europeo iguala a corea en buenos resultados. Es la unica cosa que hacemos bien.Para algo que se hace bien en este puto pais vienen los magufos de burbuja a que no se haga...
